    Frequently Asked Questions

    What temperature range do Formic Pro strips work in?

    Formic Pro strips are effective between 50-85°F (10-29°C). Avoid use above 85°F as it can stress bees and reduce efficacy.

    Leave strips in for exactly 14 days for optimal varroa mite kill rates. Remove after 14 days to prevent bee stress.

    Can I use Formic Pro strips with honey supers on?

    No, remove all honey supers before treatment. Formic acid can contaminate honey and affect flavor.

    When is the best time to apply Formic Pro strips?

    Late summer (August-September) is ideal timing, after honey harvest and before winter cluster formation begins.

    How effective are Formic Pro strips against varroa mites?

    Clinical studies show 85-95% varroa mite kill rate when used correctly in appropriate temperature conditions.

    Do I need to open the hive during Formic Pro treatment?

    No, avoid opening the hive during the 14-day treatment period to maintain proper formic acid concentration levels.

    Can weak colonies handle Formic Pro treatment?
