Cockroach bait is used to help control the beetle in a hive.
It is used to kill the beetle as well as attract them to the bait.

Place the bait into a trap.
Use only a small amount.
The most effective place to put your trap is in the hive in the bottom box on the base. (Underneath the frames)
Check your trap everytime you do a brood inspection.
Replenish the trap with more bait approximately every 3 months.
