While we were away this summer some unwanted squatters invaded our property and took up residence—paper wasps had nested beneath the back porch. I guess the carpenter bees must have invited them. They built their nest just outside the rear basement door. The same door that we use to wheel our bikes outside whenever we go biking. Both Anne and I have been stung by them. I got stung first, the day we arrived home. At the time, I was not sure if it was a sting or a bite, but the next day, Anne got stung too and she found the nest. I bought some spray, and we each sprayed them several times. The spray can claimed to have a 27′ range, but I always had to get to within a couple of feet of the nest for any accuracy.  When it felt safe enough, I chipped their nest off the bottom of the porch with a shovel and caught it in a trash can. The trash cans are by the curb now and garbage day is tomorrow.
