I have lots of paper wasps and red wasps nesting around my house and on the inside and outside of several outbuildings. They do a great job managing the fly population around here. If you have a problem with wasps trying to nest under porches at your exterior doors you should paint the underside of the porches sky blue. This will discourage nesting by making the wasps feel like the site is exposed to the weather.
