Kills ants, roaches, spiders and other pests and to help keep new ones from entering your home. This product features a sprayer for application of the fast-drying, non-staining formula.
I use this product with confidence. We get a lot of black widow spiders and by using this it tends to keep them away or it kills them. I use it inside and out. I always recommend this product to people who inquire on a good insect killer.
