Yellow Jacket Wasps don’t block them in

Its that time of year for yellow jackets to be observed nesting in you house.

DO NOT SEAL them IN. They will start to enter your living space and disperse on the inside of the structure trying to get outside. You will see them going to windows.

If you have sealed them in go back outside and unplug the area that you sealed them in and let them resume the original travel path they are familiar with.
