Where you find stinging insects depends on the type of bee or wasp you have. Aerial wasps may build nests out of paper and hang them off awnings or tree branches on your property. Ground-nesting wasps like yellow jackets may set up shop in holes or hollow trees. Bees also prefer holes and hollows and may set up their nests anywhere from hollow trees to the loose siding of your house or even the eaves of places like garages and attics.
