The shed is a radio tower. It has electronics but I want to bomb the place and then make sure no wasps or black widows ever return.
Demon WP is one of our most popular insecticides for the treatment of spiders and it is also labeled for wasps. You will mix two scoops (or two packs if purchasing the envelope) from the one pound jar to one gallon of water in a one gallon pump sprayer. It will have an outdoor residual for a month and an indoor residual for three months. It is important to treat outdoors so that they do not continue to enter the structure. Please click on the product label for specific instructions on application.
