wasp nests in hedges

Question

I had nests in hedges last fall. I have tried to locate the nests with no luck, as the shrubs are very thick. It is now early May and I have sprayed the area with two cans but they are buzzing around. There is no way to find the nests, so what can I do?

Answer 1

If you are unable to get to them or find them you may have to call a pest control professional, such as Orkin.
