When sprayed into cracks and crevices any bugs there will come out immediately and not go back. Spray bugs directly on stream setting to kill. Very effective outdoor perimeter spray, use a pump up garden sprayer on stream and spray into the crack where the siding / stucco meets the foundation. This keeps crawling insects out of your walls which means they are not in your house. Another way bugs may enter is on the drain pipe in bathrooms and kitchens.
Orange Guard works by dissolving the waxy coating on an insects exoskeleton clogging how they breathe, resulting in suffocation.
Be careful when using Orange Guard on slick floors, it will be slippery so always treat Orange Guard like a strong cleaner and wipe up with a warm damp rag. It will clean things you didn’t even know were dirty.
