Our Bait Station invites the Small Hive Beetle in, but keeps the Honey Bees out. The nasty little beetle heads in and munches on the tainted bait, gets a belly ache, and dies. Place these ready to go Bait Stations on the bottom of your hive or on top of your frames. We recommend replacing the stations about every 2-3 months. You know the station is out of commission when the bees have completely filled the grooves with propolis or you hold the station up and no longer see any bait left inside.
