The Bonide 629 Stinger Hornet and Yellow Jacket Killer Foam is designed to envelop biting and stinging insects in an entrapping foam and drop them instantly. It also coats the nest for a complete kill, with residual action to eliminate insects returning to the nest. However, it’s not specifically formulated for use on vinyl siding. For vinyl siding, I recommend using a product explicitly labeled for that purpose to avoid any potential damage.
