TopBait Plus bait helps control Small Hive Beetles in bee hive.
Middle slot of Apis Traps needs to be filled with Topbait Gel(do not put gel directly into hive box, used in traps only).
Our recommendations is keep cleaning and filling gel in Apis traps every month in Summer and Spring. In winter, 3-months should be more than enough.
Take care the trap does not become wet.
