Paper wasps, I leave alone, but yellow jackets, I kill. Nasty little
buggers and you never know when one will sting you. One sent me to
doctor with swollen hand from single sting on a finger.
Sealing the opening before or after you spray the nest will get rid of
them as the trapped ones will die off. I've had a lot of problems with
yellow jackets nesting in house through smallest crevices and have had
to seal off outside house lights as they were getting under the fixture
and getting in the wall through the conduit opening. One on front
****ch, I sealed openings and could hear buzzing in wall which eventually
stopped.
For spray, get one of those wasp and hornet sprays that reach 25 feet.
If you get in nest opening you will kill nest. When they nest in lawn,
I'll dump a gallon of pesticide solution in opening.
