The importance of tracking varroa mite populations during the mid-summer months to protect honey bee colonies and ensure a successful harvest. Because mite growth accelerates alongside healthy brood and honey production, beekeepers must regularly assess infestation levels to make informed management decisions. The author outlines four distinct monitoring techniques, including the alcohol wash, ether roll, sugar dusting, and the use of sticky boards. Three of these methods involve sampling 300 bees from the brood area, while the fourth uses a passive collection method to measure daily mite drop. By calculating the number of mites per 100 bees, beekeepers can compare their findings against established thresholds for spring and late summer. Ultimately, consistent monthly observation prevents unexpectedly high mite loads from jeopardizing the health of bees preparing for the winter season.
