When I water hose down the outside, :) an inner nest is revealed that looks like a large wasp's nest. :) The little bugger themselves like to enter the nest through a small :) hole in the bottom. They look like a house fly only twice as :) long and half as wide. :) :) -T :) Sounds like bald faced hornet, which is actually not a hornet, but a type of yellow jacket. You probably can get them to move by just constantly spraying them away with water hose, as long as it is not a large nest, but they might just move to a more undesirable place than where they are, or they may move, never to be seen again. Proper treatment would probably put you in harms way if you have to get on a ladder, and bald faced hornets are a night flyers, so a night attack is not guaranteeing safety..the pros will have the equipment to get rid of them , but it bites paying $50+ for a guy to spend 30 seconds on the job. Also, people definitely can have sensitivities to chemicals (not just pesticides), but in 18 years, even when after I finish doing a treatment on a home the home owner comes up with , "I'm very sensitive to chemicals, will I be OK?", I have yet to have someone call back stating they had problems.
