) The Rescue! W-H-Y Reusable Trap is an all-in-one trap that targets wasps, hornets, and yellow jackets. Double chambered design is baited with attractant to lure pests in. Once inside, pests can't escape and will die. The W-H-Y Trap catches queens in early spring before they build nests, and catches foraging workers all season long. Attractant will not lure beneficial honeybees. Durable construction allows you to use the W-H-Y trap for multiple seasons. Includes a 2-week supply of attractant.
