ApiGuard gel pack on top bars
1-1/2" Shim raises the roof so the bees can get to the gel.
All holes are corked, shim is under inner cover, we need to put on the telescoping cover.
ApiGuard is a Thymol gel. Easy and safe to use.
Close all cork holes, leave the main entrance open. Put a 1-1/2" Shim on top of the hive to raise the inner cover and Telescoping cover, to make room for the gel pack. One gel pack on the top hive body for two weeks, then a second gel pack for two weeks.
The warmer it is the better it works.
ApiGuard is used only in the fall.
The manufacturers literature says it is for treating Varroa mites, and has an effect on Tracheal mites and Chalkbrood.
