Establish Baseline Mite Counts All Hives
2 hoursRun alcohol wash on every hive; record mites per 100 bees and map hot colonies exceeding seasonal threshold.

Workflow
Select Treatment Product and Rotation
1 hourChoose oxalic acid, formic pro, Apivar, or thymol based on temperature, honey status, and prior rotation history.
Apply Treatment and Verify Efficacy
1–3 weeksApply per label directions; retest mite count 2–3 weeks post-treatment to confirm knockdown below 1 per 100 bees.
Build Annual Monitoring Calendar
30 minutesSchedule monthly counts April–October plus mandatory fall treatment window; set phone reminders for each test date.
Tools Used

Treatment Options by SeasonTable
Product selection guide for common scenarios.
| Product | Temp Range | Honey Supers On? |
|---|---|---|
| Oxalic acid dribble | Any — broodless best | Remove supers |
| Formic Pro | 50–85°F | Remove supers |
| Apivar strips | Above 50°F | Remove supers |
| Thymol (Apiguard) | 60–105°F | Remove supers |
Treatment Efficacy CheckFormula
Retest 14–21 days post-treatment; success = mite count reduced to < 1 per 100 bees or > 95% knockdown.
Resistance RotationStandard
Alternate between amitraz, organic acids, and thymol classes annually — same class two years running accelerates resistance.
Test Don't Guess
Prophylactic treatment without counts wastes money and builds resistance — always test first.
August Is Critical
Fall mite load determines winter survival — never skip August count and treatment.
Label Compliance
Off-label chemical use is illegal and contaminates wax — follow product label exactly.
Safety Notes
- Formic acid and oxalic acid treatments require nitrile gloves and eye protection.
- Store mite treatments locked away from children and pets — many are toxic to mammals.
