Trap is reusable and catches 18 different species of wasps, hornets, and yellow jackets. Works without killing agents. The insects are lured by the attractant and die naturally inside the trap. The W-H-Y Trap catches insects in 2 chambers, with 2 separate entrances on the top and bottom of the trap. In the top (wet) chamber, they drown in the attractant/water mixture. In the bottom (dry) chamber, they eventually dehydrate. Attractant is included and lasts 2 weeks. Refer to Model No. WHYTA-DB16 (SKU 758796) for attractant bait refill. Does not attract honey bees.
