I think you just answered your own question, his house, his wasps, he can pay for the exterminator.:yeahdisregard, stupid dial up, got beaten again.^^^^) alternatively in our council area they will remove EUROPEAN wasp colonies for FREE! but only the european wasps.
That Mortein Surface Spray is some effective ****. I spray around my house once a year. It recommends that you do it every 6 months, but I am lazy and it still seems to work after 12 months. I often find dead bugs and insects that have wandered too close to window frames etc. Never get any cockroaches in my house either. I may die a slow painful death from inhaling these toxic fumes over time, but it does a good job
