Wasps

[doc henderson]

spray when you can to get a few.  I do not think they go straight back to a nest but check any other buildings and equipment that may have a nest and spray them.  we had two in collapsed sun umbrellas this year, and one bird nest.

I have used Ortho Home Defense to spray around the house and on things such as deck railings. As a side benefit, apparently the wasps land on things such as railings and take that spray residue with them back to a nest. The result has been for several years, that I do not get the hanging wasp nests being built close by.
