If it's honey bees then call a bee guy, if it's mudwasps, indicated by the mud larvae nests they build, or paper wasps, they build the hives, a wasp spray can be used in the evening, after dark, the spray cans spray up to 18 feet or something. you'll need a flashlight to zero in on the opening of the hive. If it's mud wasps just aim , at night, and soak the larvae nests, usually clumped together with many others. The paper wasps I believe have a queen and therefore if it is displaced or terminated then your prob. will go away, but if it's mudwasps they'll keep coming back in one way or another. You can't get rid of them totally but you can cause them to move and slow them down.
