APIS Small Hive Beetle Trap has been specifically designed to retain the specially formulated Small Hive Beetle Topbait Plus bait and does not leach into the hive.
Honey bees push the beetles upwards and into the traps. The 2mm slots in the traps allow the beetle to enter, however, the bees are excluded.
Honey bees are known to partially or fully propolise trap slots. A lid inspection and a quick clean out of the propolise slots with a hive tool is recommended regularly.
