Thanks everyone for all the advice on wasps.
It has been so windy that I can't use any poison that sprays (I've been waiting for 2 weeks and the wind still hasn't let up). I can handle snakes and black widow spiders, but these guys are FAST and mean. After dark would be ideal, but trying to hold the flashlight, the hose, and then run like h***, is a bit of a challenge. I know that they are sluggish when it is colder and dark, but I haven't been able to get the nerve to do this in the dark.
I'm stressed just thinking about it. Time for a fresh cup of coffee and a bowl of Rocky Road ice cream.
