Backyard Beekeeper Varroa Mite Plan: Alcohol Wash Sampling, Mites per 100 Bees, Label Directed Treatment Choice by Season and Temperature, and a Hive Record Log
Build a season by season varroa plan for a few backyard hives: when and how to run an alcohol wash or sugar roll, how to convert the count to mites per 100 bees, which treatment fits the current brood status, temperature, and honey supers according to the product label, how to rotate modes of action, and a simple record log so every hive has a sample and treatment history.

Prompt
Act as a county beekeeping club mentor who teaches first and second year beekeepers to monitor varroa mites and choose treatments by reading the label, not by copying what a neighbor used. Inputs: - Hives: count, hive type, colony strength, and queen status for each: [HiveList] - Location and the typical daytime highs and lows for the coming weeks: [ClimateWindow] - Current season and brood status (heavy brood, reduced, broodless or nearly broodless): [BroodStatus] - Honey supers on or off, and when the next harvest is planned: [HoneySupers] - Recent mite counts with the method used (alcohol wash, sugar roll, sticky board) and number of bees sampled: [MiteCounts] - Treatments the beekeeper owns or is willing to buy, and any used in the past year: [TreatmentOptions] - The action threshold the beekeeper follows and where it comes from (club guidance, extension service, a published varroa guide): [ActionThreshold] - Output format: [Format] Generate: 1. Sampling method: step by step alcohol wash or sugar roll with about half a cup of nurse bees from a brood frame, never the queen, and how to count and convert to mites per 100 bees. Show the math on each MiteCounts entry. 2. Hive by hive status: compare each converted count with ActionThreshold and label each hive monitor, treat soon, or treat now. 3. Treatment fit table for the hives that need action: for each product in TreatmentOptions, whether it fits BroodStatus, ClimateWindow temperatures, and HoneySupers based on its label, with every specific temperature range, duration, and supers rule marked READ THE LABEL so the beekeeper confirms it on the package in hand. 4. Rotation note: group TreatmentOptions by active ingredient and recommend not relying on the same mode of action back to back. 5. A dated plan for the next eight weeks: sample dates, treatment start and end, post treatment wash to confirm it worked, and when supers can go back on per the label. 6. Safety and equipment list: protective gear the label requires (for example gloves and a respirator for oxalic acid vaporization), and storage of treatments. 7. A hive record log template with columns for date, hive, method, bees sampled, mites counted, mites per 100, action, product, lot number, and notes. Constraints: - The label is the law for pesticide use. Never recommend off label doses, homemade mixes, or treating with supers on unless the label allows it. - Do not invent thresholds; use ActionThreshold. No em dashes.

Example Input
HiveList: three Langstroth hives in Asheville area; Hive A strong double deep, Hive B medium strength, Hive C split from May with a new mated queen ClimateWindow: early September, highs in the low 80s F dropping into the 70s, lows in the 50s BroodStatus: brood still present in all three, starting to shrink HoneySupers: supers came off August 30, no more harvest this year MiteCounts: alcohol wash on September 3; A 9 mites, B 4 mites, C 2 mites; about 300 bees each TreatmentOptions: Apivar strips on hand; Formic Pro; oxalic acid vaporizer; used Apivar last fall ActionThreshold: 3 mites per 100 bees in late summer, from our club handout Format: status, fit table, eight week plan, log
Example Output
1. Sampling and math Shake bees from an uncapped brood frame into a tub, scoop about half a cup (roughly 300 bees), confirm the queen is not in the scoop, and wash in alcohol for a minute of swirling. Count mites through the mesh. - Hive A: 9 / 300 x 100 = 3.0 mites per 100 bees - Hive B: 4 / 300 x 100 = 1.3 - Hive C: 2 / 300 x 100 = 0.7 2. Status against your 3 per 100 threshold Hive A: treat now. Hive B: monitor, retest in two weeks. Hive C: monitor; the May split had a brood break, which helps. 3. Treatment fit (Hive A, brood present, supers off, highs in the 70s and 80s) | Product | Active ingredient | Brood present | Temperature | Supers | Fit | | Formic Pro | Formic acid | Works through cappings | Daytime high range on label, READ THE LABEL; low 80s may be near the top | Label rules on supers, READ THE LABEL | Good fit now if the forecast stays in range | | Apivar | Amitraz | Yes | Less temperature sensitive | Supers off for the treatment period, READ THE LABEL | Used last fall; rotate away | | Oxalic acid vapor | Oxalic acid | Reaches phoretic mites only | Wide range | READ THE LABEL | Better saved for the broodless window in late fall | 4. Rotation Apivar was your last mode of action. Use Formic Pro now and keep oxalic acid for the winter broodless treatment. 5. Eight week plan - Week 1 (Sep 7): Formic Pro in Hive A per label dose for a strong double deep. Check forecast first. - Week 2: remove pads at the label end date. Retest Hive B. - Week 3: post treatment alcohol wash in Hive A to confirm the count dropped. - Week 5: wash all three hives. Any hive at or above 3 per 100 gets a label directed treatment from a different class. - Weeks 6 to 8: reduce entrances, feed if light, and plan oxalic acid vapor once brood is gone. 6. Safety Formic Pro: acid resistant gloves, eye protection, open the pail outdoors. Oxalic acid vapor: organic vapor respirator with acid gas cartridges, goggles, gloves, stand upwind. Store treatments sealed and away from children and feed. 7. Log | Date | Hive | Method | Bees | Mites | Per 100 | Action | Product | Lot | Notes | | 2026-09-03 | A | Alcohol wash | 300 | 9 | 3.0 | Treat | Formic Pro | [lot] | Strong, brood shrinking |
