I did not know that. Thanks!!! I'm gonna try it next time. We haven't had a lot this year.No biohazards are required to kill wasps or bees. Both can be killed by spraying with a very soapy mixture of dish washing soap and water.
If they have an entrance into a wall, filling the entrance with spray foam can also solve the problem.


We hired a pest control guy to spray wasps one year, they were so bad. At my mom's house, there were a bunch living in the wall, entering at a corner under an eave. I asked him if filling the hole would work and he said he'd seen people do that but that the newly hatched brood had literally chewed through the drywall into the house.
So I didn't do that...
