This might be called the year of the wasp....I had to knock down/spray to kill two nests in and on my pickup truck. One was inside the tail gate and another was in a small nook made by the tool chest and side of the truck...now when I go out to drive the truck I have to make a circuit to see I they have found another place to build their nest. These are paper wasps and I have discovered they can build a nest in very short time. Clever buggers, but I have been stung and it is not nice; so with respect I have a can of death that will spray up to a ten foot distance. Good by and go nest elsewhere....though not in the house thank you very much.
