Will Demon WP work on wasps and yellow jackets?
Demon WP will kill wasps and yellow jackets as long as you apply it to a place where they will come into contact with it. If you know where they are going in and out of their nest, you can treat that area directly in the early morning or late evening when they are not active. If you do not know where the nest is then they can only be affected if they land on a surface that you treat.
