# Bees

Managing bees well means understanding their biology first and intervening only when necessary. A colony managed as a living superorganism — not a honey machine — is more productive, more resilient, and less dependent on the beekeeper than a colony managed through constant manipulation. Your job is to read what the colony needs at each point in the season and respond proportionately.

The same farm chemistry choices that degrade soil biology degrade bee health. Systemic insecticides and fungicides that harm the soil food web accumulate in hive wax and impair queen fertility, navigation, and immune function. A commitment to reducing pesticide inputs for soil biology reasons is simultaneously a commitment to pollinator health — the connection runs in both directions.

**How this skill works:** Each sub-tool pauses at a **Checkpoint** to confirm the assumptions it is about to build on before producing output. A recommendation built on a wrong assumption wastes time and money — confirm the checkpoint before acting. Each sub-tool ends with **Next steps** — the skills worth running once you have acted on this one.

## Expert Lineage

*The thinkers whose frameworks underpin this skill — and what they specifically discovered that changes how you farm.*

**Thomas Seeley — Superorganism Biology**
Seeley's decades of research at Cornell established that a honeybee colony is best understood as a single organism, not a collection of individuals. His specific finding: wild colonies in tree cavities maintain a nest cavity of around 40 litres with 15mm entrance holes and significant distance between colonies — conditions almost never replicated in commercial Langstroth management. This matters because overcrowded, closely spaced colonies with large entrances are structurally predisposed to disease and swarm suppression failure. *Honeybee Democracy* documents the decision-making biology of swarms; understanding this changes how you read pre-swarm behaviour and design prevention.

**David Heaf — Bee-Centric Management**
Heaf's framework shifts the question from "how do I maximise the colony's output" to "what does the colony need to thrive." His specific contribution: conventional management that suppresses swarming, uses a single brood box, and relies on frequent inspection disrupts the colony's biological rhythms and selects for traits that suit the beekeeper rather than the bee. *The Bee-Friendly Beekeeper* documents management decisions that reduce beekeeper intervention while improving colony health and winter survival.

**Johann Thür — The Warré System**
Thür developed the Warré hive — a vertical top-bar system designed around the bee's preferred nest structure — as a minimal-intervention alternative to moveable-frame systems. His finding: colonies allowed to build natural comb from starter strips in Warré-sized boxes maintain better brood temperature, develop more consistent brood pathogen resistance, and swarm less problematically than colonies in flat-frame Langstroth hives. The practical implication: natural comb renewal (replacing old dark comb regularly through nadiring) removes accumulated chemical residues and pathogen loads without treatment.

**Phil Chandler — Accessible Natural Beekeeping**
Chandler's contribution is demonstrating that natural beekeeping — top-bar hives, minimal intervention, no synthetic treatments — is practically achievable without specialist expertise. His specific finding: colonies allowed to rear their own queens from local genetics, rather than being requeened with commercially produced stock, develop locally adapted traits within 3–5 seasons. *The Barefoot Beekeeper* documents this approach for beginners. Practical implication: buying queens is a short-term solution; developing your own stock is a long-term one.

**Elaine Ingham — Farm System Connection**
Ingham's soil food web framework connects to bee health through the farm's chemistry profile. Her documented finding: the same soil biology that collapses under systemic fungicide use is the foundation for the diverse forage ecology that sustains healthy bee populations. Farms with high fungicide use have impoverished forage ecology and produce pollen and nectar with compromised nutritional profiles. Before adding inputs — synthetic or organic — the beekeeper should ask whether they affect the forage landscape the bees depend on.

**Dave Goulson — Pollinator Ecology**
Goulson's research at Sussex established that foraging range, forage diversity, and pesticide exposure are the three primary drivers of colony health in the landscape. His specific finding: a colony within 3km of diverse, pesticide-light farmland with year-round forage can sustain itself without the supplementary feeding that has become normalised in managed beekeeping. *A Sting in the Tale* documents the evidence for landscape-level management as the most cost-effective pollinator intervention.

## Which tool fits

| You need to... | Tool |
|---|---|
| Know what to do in each season | seasonal-management |
| Inspect a hive and know what you are looking at | inspection |
| Identify or prevent a swarm | swarm-management |
| Manage Varroa mite load | varroa-management |
| Diagnose a disease or disorder | disease-diagnosis |
| Move toward lower-intervention beekeeping | natural-beekeeping |

## Routing Decision

- **New to bees or planning ahead for the season** → seasonal-management
- **Hive inspection underway or results to interpret** → inspection
- **Bees gathering on the outside of the hive, or clustered in a tree** → swarm-management
- **Mite count is high or you need a treatment plan** → varroa-management
- **Something looks wrong — larvae, brood, or adult bees** → disease-diagnosis
- **Want to reduce treatments, try top-bar or Warré, or develop local genetics** → natural-beekeeping
- **Unsure** → inspection first; most problems show up in a thorough hive inspection

---

## Seasonal Management

*Defines what to do in each season and why, so management is ahead of the colony rather than reactive.*

Bee management that stays ahead of the colony's biological cycle costs far less time than reactive management. The colony has predictable biological phases — build-up, peak population, swarm impulse, post-swarm recovery, winter preparation — and the beekeeper's job is to act in the right phase, not after the window has passed.

**The apiary calendar — temperate northern hemisphere baseline; adjust timing for latitude:**

### Winter (December – February)
The colony is in cluster — minimal disturbance required.

| Task | Timing | Purpose |
|---|---|---|
| Check heft (colony weight) | Monthly | Confirm adequate stores |
| Check entrance is clear | After snow | Prevent suffocation |
| Mouse guard check | Ongoing | Mice enter through large entrances |
| Records review | January | Plan the coming season |

Do not open the hive below 10°C — breaking the winter cluster forces the bees to re-form it at significant energy cost. A quick heft — lifting the back of the hive — is all that is needed to assess stores.

### Early Spring (March – April)
The colony begins brooding ahead of the first nectar flow. This is the highest-risk period — brood is expanding but foraging is limited, and stored reserves are running low.

| Task | Timing | Purpose |
|---|---|---|
| First inspection | When temperatures consistently reach 14°C | Assess winter survival, queen status, stores |
| Varroa count | First inspection | Set baseline before brood expands |
| Emergency feeding if needed | First inspection if stores are low | A colony at risk of starvation cannot wait |
| Remove mouse guard | When night frosts are passed | Allow full entrance opening for spring build-up |

### Late Spring (May – June)
Peak build-up. Queen laying at maximum rate. Swarming impulse peaks when the colony reaches approximately 80% of available comb capacity. This is the season where most colonies are lost to swarms.

| Task | Timing | Purpose |
|---|---|---|
| Weekly inspection | Every 7–10 days | Detect queen cells before swarming |
| Add supers | When bees are covering 80% of existing comb | Prevent congestion — the primary swarm trigger |
| Swarm prevention decision | On finding charged queen cells | See swarm-management |
| Varroa mid-season check | June | Assess mite build-up before peak honey flow |

### Summer (July – August)
Peak honey production. Colony population begins to decline after the summer solstice as the queen reduces laying ahead of winter.

| Task | Timing | Purpose |
|---|---|---|
| Harvest timing assessment | When cells are 80%+ capped | Moisture content stable below 18.5% once capped |
| Post-harvest Varroa treatment | After honey harvest, before new winter bees are laid | Most effective treatment window |
| Winter stores assessment | August | Colony needs 15–20kg stores for winter |
| Begin feeding if needed | Late August | Stimulate build-up of winter bees with winter bee larvae |

### Autumn (September – October)
Preparing for winter. The colony is rearing the long-lived winter bees that will carry it through to spring.

| Task | Timing | Purpose |
|---|---|---|
| Oxalic acid treatment | After broodless period (November in temperate climates) | Most effective Varroa treatment with no brood |
| Reduce entrance | October | Defence against wasps and robbing |
| Final stores check | October | Confirm 15–20kg total weight |
| Mouse guard | October | Before mice seek winter shelter |
| Remove supers | Before first frost | Consolidate heat into brood boxes |

**Checkpoint — confirm before finalising:**
- What climate zone and hemisphere are you in? All dates above are temperate northern hemisphere and shift significantly for southern hemisphere, subtropical, or high-altitude locations.
- What hive type — Langstroth, National (UK), Warré, top-bar? Task timing and methods differ by hive format.
- Are you managing one hive or an apiary of multiple colonies? Swarm and disease management decisions scale differently.

Providing calendar advice without confirming hemisphere and hive type produces recommendations that are wrong by six months or incompatible with the hive format.

**Output:**
```

## Inspection

*How to open a hive, read what you find, and make the right call.*

A good inspection answers three questions: Is the queen present and laying well? Are stores adequate? Is there anything abnormal in brood, adults, or hive condition? Every other observation is secondary to these three.

**Before you open:**
- Temperature at least 14°C, ideally 16°C+. Avoid cold, wet, windy days.
- Wear appropriate PPE — veil as minimum. Gloves reduce dexterity but reduce stress for nervous beginners.
- Light smoker with cool white smoke — cool smoke is calmer than hot smoke.

**Smoke protocol:**
- 2–3 puffs at the entrance before opening.
- Wait 30 seconds.
- 1–2 puffs under the crown board before lifting.
- Smoke drives bees downward and away from the frame you are examining.
- Never smoke directly onto open brood — it stresses larvae.

**Working the hive:**
1. Remove and set aside the crown board or inner cover.
2. Remove the first frame from one end — this creates space to work without rolling bees.
3. Examine each frame in sequence, holding it vertically (prevents queen falling).
4. Return each frame to exactly its original position before moving to the next.
5. Work quickly and confidently — hesitation and fumbling disturbs bees more than speed.

**What to look for — frame by frame:**

| Observation | Healthy | Concern |
|---|---|---|
| Eggs | Upright, single egg per cell, glistening | Absent — queen issue; multiple per cell — laying workers |
| Young larvae | C-shaped, pearly white, lying in royal jelly | Brown, twisted, or dry — disease indicator |
| Capped brood | Even, slightly domed, consistent coffee-brown | Sunken, perforated, or dark — see disease-diagnosis |
| Queen | Present, elongated abdomen, deliberate movement | Absent — check for eggs; confirm before re-queening |
| Stores | Honey capped above and beside brood; pollen in arc around brood | Less than 2 frames of capped stores — feed |
| Queen cells | Cups present (normal); charged cells (peanut-shaped, raised wax, contains larva in royal jelly) | See swarm-management |
| Varroa | Occasional mite on bees is normal | White mite on larvae or many on adults — check count |
| Temper | Steady on comb, minimal following | Flying aggressively at face or following well beyond hive |

**Recording the inspection:**
Record every inspection. Minimum record: date, colony ID, queen status (seen/eggs/cells), brood quality, stores estimate, Varroa count if done, action taken.

A colony that was queenright three weeks ago and has no eggs now has been queenless for 3 weeks — known only if you have records.

**Checkpoint — confirm before finalising:**
- What hive type are you working with? Frame layout and what to expect varies by system.
- How experienced is the beekeeper — first-season or experienced? Guidance on what "normal" looks like needs calibration to experience level.
- What season is this inspection? Queen cells in late spring are a swarm signal; in late summer, they may be supersedure — the management response differs.

Recommending a swarm prevention response to supersedure cells, or vice versa, makes the wrong intervention at the wrong time.

**Output:**
```

## Swarm Management

*Reading swarm signs, deciding how to respond, catching a swarm that has already left.*

Swarming is reproduction at the colony level — it is healthy biology, not failure. A colony that swarms is a colony expressing a functional superorganism response to overcrowding. The beekeeper's role is to manage the impulse in a way that preserves productive colonies and prevents uncontrolled swarming that loses bees to inaccessible locations.

**Reading the colony — swarm progression:**

| Stage | Signs | Time to swarm |
|---|---|---|
| Pre-swarm build-up | Bees clustering outside hive ("bearding"), congestion in brood box | Weeks — not imminent |
| Queen cell cups | Empty or lightly waxed cup-shaped cells on bottom of frames | Not yet charged — 1–2 weeks |
| Charged queen cells | Peanut-shaped raised cells, royal jelly visible, larva inside | 7–10 days to swarm |
| Sealed queen cells | Cells capped — dark, ridged wax | 2–5 days to swarm — very close |
| Post-swarm | Swarm has departed; original colony has emerging queens | Swarm has happened |

**Prevention — the decision sequence:**

**Step 1: Prevent congestion.** Add supers before the bees run out of space. A congested colony swarms; a colony with room does not need to. This is the most cost-effective prevention.

**Step 2: Artificial swarm on finding charged cells.** Move the original queen and one frame of open brood with adhering bees to a new hive body on the original site. Leave the original hive in a new location with all the sealed brood and queen cells. The flying bees return to the original site with the queen; the nurse bees raise a new queen in the original hive. Result: effectively mimics a natural swarm without losing any bees.

*Artificial swarm method — step by step:*
1. Find the queen. Mark her if you can.
2. Set up a new hive body with foundation or drawn comb on the original stand.
3. Place the frame containing the queen (and eggs/young larvae) into the new hive body.
4. Fill remaining space with foundation or drawn comb.
5. Move the original hive to a new position at least 3 metres away.
6. Select the best single queen cell in the original hive — destroy all others to prevent multiple virgin queens and subsequent casts.
7. Seal both hives. Check original hive in 10 days for any emergency queen cells to remove.

**Step 3: Demaree method (less disruptive, keeps both hives together).** Move all frames with queen cells to a super above a queen excluder; leave the queen below. Flying bees return to the queen below; nurse bees continue rearing the queens above. Harvest or combine the above-board colony after the new queen has mated.

**Catching a swarm that has already left:**

Swarms are docile — they have no home to defend. A fresh swarm hanging in a cluster can be collected easily.

1. Position a hive box beneath the cluster.
2. Shake or brush the cluster firmly into the box in one motion — you need the queen to go in.
3. Watch for bees fanning at the entrance with Nasonov glands exposed — this means the queen is inside.
4. Leave the box until dusk; most flying bees will have entered.
5. Close the entrance and move to the apiary overnight.

If the swarm is in an inaccessible location (high in a tree, inside a wall): do not attempt to retrieve it without appropriate equipment. Wait — they may move on within 24 hours as they scout for a permanent site.

**Checkpoint — confirm before finalising:**
- What stage are the queen cells at? The response to cups is different from the response to sealed cells.
- Does the beekeeper have a spare hive body available for an artificial swarm? If not, the method needs adapting.
- Is this the first swarm impulse of the season, or has the colony already cast (sent a secondary swarm)? A cast swarm means a virgin queen is present, and a different response is needed.

Recommending an artificial swarm when the original queen has already left wastes the move — confirm queen presence before executing.

**Output:**
```

**Next steps:**
- Run **inspection** (within this skill) at 10-day intervals after an artificial swarm to confirm the new queen has mated and is laying.
- Run **natural-beekeeping** (within this skill) if frequent swarming suggests that developing locally adapted swarmy genetics is preferable to constant suppression.
- `/s4ag-biodiversity` — a colony that swarms into an unmanaged location is a pollinator resource; ensure habitat is available within the farm landscape.

## Varroa Management

*Assessing Varroa mite load and choosing a proportionate, effective response.*

Varroa destructor is the most significant health threat facing managed colonies in most of the world. An untreated colony will die from Varroa-related virus amplification, typically within 2–4 years of the mite arriving. Integrated Varroa management (IVM) uses monitoring to time interventions, combines cultural and chemical tools, and reduces synthetic treatment frequency to minimum necessary.

**Step 1: Count before treating.**

Never treat without a count — counts determine whether treatment is needed, and when to treat again.

*Alcohol wash method (most accurate):*
1. Collect 300 adult bees from a frame adjacent to brood (not the queen frame).
2. Place in a jar with 70% alcohol.
3. Shake for 1 minute; count mites in the alcohol.
4. Mite load = (mites counted / 300) × 100 = mites per 100 bees.

*Sugar roll (live bees, slightly less accurate):*
Same method with icing sugar instead of alcohol; bees survive. Underestimates by 20–30% compared to alcohol wash.

*Sticky board (simplest, least accurate):*
Place a greased board below the hive for 24 hours. Count mites. Divide by a correction factor for season (12 in winter, 6 in summer) to estimate mites per 100 bees.

**Threshold guide:**

| Mite count (per 100 bees) | Season | Action |
|---|---|---|
| Below 2% | Any | Monitor; no treatment needed |
| 2–3% | Spring/summer | Treatment recommended |
| Above 3% | Any | Treat promptly |
| Below 1% with no brood | Winter/broodless period | Oxalic acid highly effective |

**Treatment options — decision table:**

| Treatment | Active | Brood penetration | Season | Notes |
|---|---|---|---|---|
| Oxalic acid (dribble/sublimation) | Organic | No — broodless only | Broodless winter period | Most effective treatment; accepted in organic systems |
| Oxalic acid (extended-release strips) | Organic | Yes — partial | Any brood stage | Less effective than broodless treatment; useful mid-season |
| Thymol (Apiguard, ApiLifeVar) | Organic — essential oil | Yes | Late summer (above 15°C) | Temperature-dependent; do not use during honey flow |
| Formic acid (MAQS, Formic Pro) | Organic | Yes | Summer (above 10°C) | Penetrates capped brood; good mid-season option; some queen risk |
| Amitraz (Apivar strips) | Synthetic | Yes | Post-harvest | Highly effective; 6–8 week exposure; wax contamination accumulates |
| Fluvalinate (Apistan) | Synthetic | Yes | Post-harvest | Resistance widespread — test efficacy before relying on it |

**The integrated approach:**

1. **Post-harvest treatment** (August–September): Apply thymol or formic acid immediately after honey harvest before winter bees are being reared.
2. **Broodless winter treatment** (November–January): Apply oxalic acid by sublimation or dribble when colony is fully broodless. This single treatment can reduce mite load by 90%+ and is the most cost-effective intervention.
3. **Emergency summer treatment** (if count exceeds 3% mid-season): Formic acid or extended-release oxalic acid.

**Cultural controls that reduce Varroa burden:**

| Control | Mechanism | Ease |
|---|---|---|
| Brood break (queen removal for 21 days) | No brood = no reproductive cycle for mites; all mites exposed | Moderate |
| Drone comb removal | Varroa preferentially infests drone brood; remove sealed drone frames | Easy |
| Nucleus colony splits | Forced brood break across the year | Easy |
| Small cell comb | Contested; some evidence of reduced mite reproduction | Difficult to establish |

**Soil food web note:** Systemic pesticides — particularly neonicotinoids — impair queen fertility, navigation, and immune function in bees at sub-lethal doses. The same farm inputs that damage soil biology accumulate in hive wax and amplify Varroa-associated virus transmission. Reducing farm chemistry is a Varroa resilience strategy as well as a soil health strategy.

**Checkpoint — confirm before finalising:**
- Has a mite count been done? Never recommend treatment without a count.
- Is it the post-harvest treatment window, a broodless winter window, or an emergency mid-season situation? Each calls for different products.
- Is the beekeeper organic or conventional, and are there honey supers on the hive? Several treatments cannot be used during honey flow.

Recommending treatment without knowing whether honey supers are on risks contaminating harvestable honey.

**Output:**
```

- `/s4ag-pests` — the farm-wide IPM approach; connect bee health decisions to the broader pest management strategy.

## Disease Diagnosis

*Identifying what is wrong with the colony and deciding on an appropriate response.*

Most brood problems are diagnosed visually. Adult bee problems require more inference. The critical first step is always to identify what you are dealing with before acting — treating AFB as chalkbrood, or vice versa, wastes time and harms the colony.

**Work through this decision sequence before concluding:**

1. Is the problem in the brood, adults, or whole-colony behaviour?
2. What does the affected material look, smell, and feel like?
3. Is the problem spreading rapidly or localised?

---

**Brood diseases — identification guide:**

| Condition | Larvae/pupae appearance | Smell | Capping | What to do |
|---|---|---|---|---|
| American Foulbrood (AFB) | Brown-black, sunken, ropy (stretches 2cm on matchstick) | Rotting-fish smell | Perforated, sunken | NOTIFIABLE — contact your local bee inspector immediately. Do not move hive or equipment |
| European Foulbrood (EFB) | Yellow-brown, twisted, non-ropy | Sour/vinegary | Normal capping (uncapped larvae affected) | Notifiable in UK; improve nutrition and consider requeening with resistant stock |
| Sacbrood | Brown-black, head turned upward, sac of fluid under cuticle | Mild | Normal or perforated | Usually self-limiting; requeen if persistent |
| Chalkbrood | White chalky mummies, sometimes with black patches | None | Bees remove mummies — seen on bottom board | Improve ventilation; requeen if severe |
| Varroa | Deformed wing, stunted bees, white mites visible | None | Sunken or normal | See varroa-management |

**Critical rule on AFB:** If you see ropy brood with a rotting smell, stop the inspection and do not move any equipment between hives. AFB spores survive in wooden equipment for over 70 years and contaminate every hive the equipment touches. This is a notifiable disease in most jurisdictions — contact your national or regional bee health authority before taking any other action.

---

**Adult bee problems — identification guide:**

| Condition | Signs | Cause | Action |
|---|---|---|---|
| Nosema | Dysentery trails on front of hive; weak spring build-up; dead bees crawling | Nosema apis or ceranae (fungal gut pathogen) | Fumagillin (where licensed); improve ventilation; ensure adequate winter stores |
| Chronic Bee Paralysis Virus (CBPV) | Shiny, hairless, black bees; trembling; piles of dead bees outside hive | Virus, spread by crowding | Requeen; reduce colony density in apiary |
| Deformed Wing Virus (DWV) | Small bees with crumpled, deformed wings; unable to fly | Varroa vector | See varroa-management — DWV is a Varroa symptom |
| Starvation | Bees head-down in cells; sudden population collapse in cold weather | Inadequate stores | Emergency feeding immediately — fondant or syrup |
| Pesticide poisoning | Sudden mass die-off; dead bees in large numbers at entrance; normal brood | Acute pesticide exposure | Document evidence; report to authorities if suspicious; cannot reverse acute poisoning |

---

**When to call a bee inspector:**
- Any suspected AFB or EFB — these are notifiable diseases in most countries.
- A sudden die-off that might be acute pesticide poisoning — especially if neighbouring farms have recently sprayed.
- Any situation where you are unsure and the colony is declining rapidly.

**Soil food web note:** Chronic pesticide exposure at sub-lethal doses (neonicotinoids, fungicides) significantly impairs the immune system of individual bees, making colonies more susceptible to Nosema, viruses, and Varroa-vectored pathogens. A colony experiencing recurrent disease that has no obvious management explanation should be assessed in the context of the farm's pesticide use and surrounding landscape.

**Checkpoint — confirm before finalising:**
- Is the problem in brood, adults, or whole-colony behaviour? The diagnostic pathway diverges immediately.
- What does the affected material smell like? AFB has a distinctive rotting-fish smell that distinguishes it from other brood diseases before any visual ID is certain.
- Has the ropy test been done? Pull a discoloured larva with a matchstick — if it stretches more than 1cm in a continuous thread, stop and call the bee inspector.

Skipping the ropy test on suspect brood risks missing AFB and spreading the most destructive hive disease in beekeeping.

**Output:**
```

## Natural Beekeeping

*Lower-intervention beekeeping — reducing treatments, developing local genetics, choosing hive systems that work with the bee's biology.*

Natural beekeeping is not an absence of management — it is a different management philosophy that prioritises the colony's biological autonomy over the beekeeper's control. The goal is colonies that are locally adapted, resilient, and less dependent on the beekeeper's intervention than conventionally managed colonies.

This sub-tool documents three areas: hive type choice, treatment reduction strategy, and genetics development.

---

### Hive type comparison

| Hive Type | Description | For who | Limitation |
|---|---|---|---|
| Langstroth | Standard moveable-frame; dominant commercial hive worldwide | Any beekeeper; best for honey production | Requires regular frame inspection; designed for maximum extraction |
| National (UK) | Smaller moveable-frame; standard in UK beekeeping | UK beekeepers; easy to source equipment | Same frame-management requirements as Langstroth |
| Warré | Vertical top-bar; nadired from below as colony grows; minimal inspection | Beekeepers wanting low-intervention | Lower honey yield; less familiar to conventional beekeeping services |
| Top-bar horizontal | Single horizontal bar system; no frames; natural comb | Low-cost entry; warmer climates | Cannot use standard queen excluders or supers; honey extraction more involved |

**Choosing a hive system:**
If you are new to beekeeping and want to eventually manage naturally, start with a Langstroth or National and develop the skills to read colonies before removing the intervention tools. Switching to a top-bar or Warré system without inspection skills first makes it difficult to diagnose problems that require intervention.

---

### Treatment reduction pathway

**Stage 1: Monitor rather than treat on calendar.**
Replace calendar-based Varroa treatment with count-triggered treatment. Many beekeepers treating preventively are treating colonies that do not need it — and selecting for Varroa resistance is impossible if you are constantly intervening before mite loads build.

**Stage 2: Shift to organic treatments only.**
Replace synthetic amitraz and fluvalinate treatments with organic oxalic acid and thymol. Organic treatments do not accumulate in wax, and colonies treated organically maintain a cleaner hive environment. The treatment-free community's objection to synthetic treatments is primarily about wax contamination and its long-term effects on colony health.

**Stage 3: Extend the treatment interval.**
Once mite monitoring is established and counts are consistently low, extend treatment intervals. Some colonies maintain low mite loads without annual treatment — these are candidates for the genetics development stage.

**Stage 4: Develop locally adapted genetics.**
Allow your best-performing, lowest-mite colonies to raise queen cells and mate with local drones. Over 3–5 seasons, this develops stock adapted to your local forage, climate, and Varroa pressure. This is the natural beekeeping community's long-term Varroa management strategy — locally adapted hygienic behaviour rather than chemical management.

*This is not treatment-free beekeeping — it is the pathway toward it. Removing all treatments before local genetics are established kills colonies.*

### Treatment-free beekeeping — what it requires

Treatment-free beekeeping is achievable but requires:
- Locally adapted genetics with documented hygienic behaviour (VSH — Varroa-Sensitive Hygiene trait)
- Rigorous mite monitoring to catch colonies in decline before they collapse and spread mites to neighbours
- Willingness to lose colonies that cannot maintain themselves — and to learn from them
- A management philosophy that accepts swarming as part of the biological cycle rather than a failure

The trap: declaring a hive "treatment-free" and watching it die while not treating is not natural beekeeping — it is neglect. Treatment-free beekeeping requires more monitoring and more decisive action on failing colonies than conventional beekeeping does.

### Forage and landscape

A colony in good forage is more resilient than a colony in poor forage — regardless of management approach. Year-round forage in a diverse, pesticide-light landscape is the foundation of natural beekeeping:

| Season | Key forage species | Notes |
|---|---|---|
| Early spring | Willow, hazel, crocus, blackthorn | Pollen essential for brood build-up; provide before first inspection |
| Late spring | Fruit blossom, dandelion, clover | Peak protein season; maximise with unmown areas |
| Summer | Lime tree, borage, phacelia, bramble | Nectar flow; main honey crop |
| Autumn | Ivy, Michaelmas daisy, heather (moorland) | Critical late stores |
| Year-round | Diverse hedgerow and wildflower species | Continuous low-volume forage keeps colonies in condition |

**Checkpoint — confirm before finalising:**
- What is the beekeeper's experience level? A first-year beekeeper considering a Warré hive or treatment-free approach needs different guidance than an experienced beekeeper planning a transition.
- What is the current Varroa management history? Colonies that have been treated conventionally are not ready to go treatment-free immediately.
- What does the surrounding landscape look like for forage? A colony in poor forage landscape cannot compensate through management alone.

Recommending a treatment-free approach to someone in a low-forage, high-pesticide landscape sets them up for failure.

**Next steps:**
- `/s4ag-biodiversity` — design year-round forage habitat; natural beekeeping depends on landscape more than any other management factor.
- Run **varroa-management** (within this skill) with a focus on monitoring and organic-only treatments as the bridge toward treatment reduction.
- `/s4ag-regenerative` — the farm-wide pesticide reduction that makes natural beekeeping viable operates at the whole-farm level.
