Mortein PowerGard Crawling Insect Spray Barrier Outdoor 350g is our outdoor barrier spray that protects your family home for up to 9 months by creating a barrier against spiders and crawling insects outside, before they get inside. To provide the best barrier protection, simply spray on non-porous surfaces around the house perimeter, under eaves, around foundations, under window frames, behind downpipes and the underside of guttering, under the house, around sheds in sheltered areas to deter spiders and crawling insects on contact and flush them out from where they hide.
