FAM-Dispenser
Adjustable Formic Acid Treatment for Varroa Management
The FAM-Dispenser is a reusable formic acid evaporator designed to provide controlled release of 65% liquid formic acid for the management of Varroa destructor mites in honey bee colonies. Its adjustable design allows beekeepers to regulate evaporation rates according to hive size and environmental conditions, supporting effective mite control throughout the treatment period.
Compact and easy to use, the dispenser is positioned directly above the brood area where formic acid vapours are distributed throughout the hive. The durable, reusable construction provides long-term value for both hobbyist and commercial beekeepers, making it a practical tool for seasonal Varroa management programs.
