Turned up as arranged. Wasps were emerging in bathroom of our thatched cottage with no obvious point of entry. The operator was at a loss as to what to do. I suggested he spray the hot water cupboard in the bathroom and he suggested spraying the tiny attic. I climbed up and pulled hatch back. Provided him with a DECENT torch. but he was reluctant to stick his head into attic. When he did so, he immediately came down, brushing his head in panic thinking wasp was in his hair. It was cobweb. I was not impressed, having myself braved bathroom (suitably dressed) where window had been covered in wasps previous week, and released them. I'm 72 years old. I was not impressed by the operator's lack of know-how and anxiety. Paid the fee.y husband complained. Operator returned. Sprayed outside of bathroom window then left. The Wasps kept appearing for next 4 to 5 months then gradually stopped. Would not recommend.
