I don't know what has been going on the last few years, but the yellow jackets and red wasps have been crazy. Every time I turn around they are making a new nest somewhere. I usually use plain old soapy water to kill them which does a good job. Last year, I used my boy's water gun with the soapy water and it works really nice. It usually has enough power to knock down the nest too.
It's one of those "super soaker" types. Just mix a bucket of some really soapy water and enjoy.
