Treating for Varroa

Now is the time to treat for Varroa. Always follow the instructions on the label. There are several products that can be used:
ApiGuard: Thymol Gel, package treats 5 colonies, shelf life is more than a year. Tin of thymol gel. The tin is placed on the top bars of the brood box. Honey must be removed before application. A 1-1/2" shim must be placed on top to raise the roof. Bees need to be able to get to the thymol gel and need the raised space to get the gel. Very safe easy to apply. Temperature critical. If it is to cool this will not work properly. Temperatures should be in the 70's and 80's. Treatment, one tin for two weeks then add another tin. leave both tins on for six weeks. The slide should be in on any screened bottom boards, all holes plugged and the main entrance left wide open.
