Earth’s Ally Bug Barrier™ kills and repels common household crawling insects such as ants, roaches and spiders. Formulated with encapsulated essential oils, it delivers long-lasting insect repellency for up to 90 days after application. With a fresh, peppermint scent, the non-staining formula can be applied on hard, non-porous surfaces where crawling insects may enter or hide, such as window and door frames, in basements and near sinks and appliances.
