In the autumn my window cleaner alerted me to a problem with wasps behind the hanging tiles of my house at 1st floor level. After research online I appointed Wynsdale to deal with matter. The operative who attended quickly identified multiple nests on each side of the 4 windows on the rear of my property. Within an hour the nest sites had been treated and after about 24 hours all wasp activity had ceased. This gentleman was totally professional. He was very polite, super efficient and extremely friendly. In short, I could not have wished for a better experience.
