hi mate, we do wasps, its worth doing the course tho, pest solutions ltd at Bury St Edmunds run a one day course, also it's not illegal to dust bees, there are a few extra dos and donts but if they become a pest or are damaging property and can't be safely removed then you can dust, the course does cover a lot of basics ie, loft surveys, bats, lagging the water tanks, biology of the wasp, hornet etc, the bloke who runs the busines is called Graham and used to be the training manager for Rentokill, they will also give you a good indicator of what equipment to carry and will also offer advice over the phone on any awkward situations.
Hope this helps
Graham
