I have wasp nest buried all around my backyard. Initially there were a few and they were farther back in my yard. My husband and I bought about 40 cans of spray
(raid) and we saturated these nest. Although the spray killed the wasps that were visible, it did nothing for the nest except cause them to mutiply. Now we are knee deep in nest and they have come all the way to my door. What can I do to make sure this doesn't happen next year?
