Raid® Disposable Yellow Jacket Trap solves a difficult problem posed by yellow jackets, a type of wasp. Unlike other types of wasps that nest in eaves and trees, yellow jackets nest underground or behind walls, making it hard to kill them where they live. But because they are aggressive foragers, they will be lured by the trap's specially formulated non-toxic attractant. Use the trap in spring to catch yellow jacket queens and to reduce the overall population before it grows. In the summer and fall, put out more traps to catch the workers foraging for sugars. The trap comes with a twist-tie so you can easily hang it in a tree or bush or even put it on a flat surface. With its unique lantern design, the trap easily blends into your yard and its decor. For best results, use one trap for each 20 feet x 20 feet area.
