Place pouches to disrupt a spider’s sophisticated senses, keeping them out of treated areas with a scent pleasant to humans, but offensive to spiders. Spider legs contain the organs for hearing, touch, and smell. All of these senses are highly developed and very sensitive. Our proven blend of citronella, lemongrass, and rosemary interferes with spiders’ ability to sense their prey, as well as helps to repel various types of prey from the treated area, (citronella & lemongrass commonly repels flies and small winged insects) causing spiders to stay away. Use one pouch per entryway, dormer; two pouches per small room. Increase the number of pouches as needed until desired results are obtained and replace when the scent has diminished (usually 30-60 days).
