Made with oils of Citronella, Lemongrass and Rosemary Stay Away Spiders is as eco-friendly as it is high performance. Stay Away Spiders pouches disrupt a spider's sophisticated senses, keeping them out of treated areas with a scent pleasant to people, but offensive to spiders. Use one pouch anywhere webs or spiders are noticed, such as basements, closets, and attics, or other places you want to prevent spiders from entering. Increase number of pouches until desired results are obtained. Replace when scent has diminished (usually 30-60 days).
