Hi Peter, Hi All, Last summer I had the chance to use Apiguard. I wanted to test if my bees become resistant to our drug used to fight against Varroa Distructor. The Apiguard is a slow release gel and the active ingredient is thymol. The drug extremely easy to use placing the opened tray with gel face upwards in the top of brood frames. The bees will do the distribution within the bee colony is assured by vapour release and also by the bees social behavior (feeding exchange and cleaning activities). The efficacy against three types of hive pest makes this drug a very good product (Varroa, tracheal mite and chalkbrood.). My observation. I think that the bees with high Hyg test will clean faster the Apiguard.. So when you treat with Apiguard you see if your bees have high Hyg behaviour. The efficacy to 10 colonies treated with Apiguard was about 93-95%.
