Spring is around the corner. No more snow, ice and frozen shingles to prevent roof inspection. For those inspectors who walk the roofs and allergic to and get severe reactions from yellow jacket and similar insect stings should carry some topical insect anesthetic such as Sting-KIll and Benadryl - an over the counter antihistamine drug in their inspection tool kit as a precautionary measure.
Anybody subject to severe allergic reaction should carry injectable anti-venum ampoules.
Contact your family doctor / health care provider for proper guidance.
