Did an alcohol wash or sugar roll on one hive? Enter what you counted and get mites per 100 bees. Everything runs in this page.
| Mites per 100 bees | What many guides say |
|---|---|
| Under 2 | Low. Keep monitoring on a regular schedule. |
| 2 to 3 | Many extension guides treat this range as the point to plan a response. |
| Above 3 | High. Follow your local extension or bee inspector guidance and the product label. |
Thresholds vary by region and season. Check your local extension service or bee inspector; this page only does arithmetic.
Mites per 100 bees = mites counted divided by bees sampled, times 100. A level half cup of bees is commonly taken as about 300 bees, so 6 mites in half a cup is 2 per 100. Count from brood-nest frames and avoid the queen.
Log the date, hive, mite count and what you did next. The Backyard Beekeeping Record Book ($7, printable) has inspection sheets, a mite count log, feeding and harvest pages for 1 to 10 hives. Also try the sugar syrup calculator.
