We used to have seriious issues with red wasps and those mean ass yellow jackets. Especially since our house is wood.
I subscribe to Mother Earth news and in one of the issues was a method of ridding wasp invasion.
I had an empty miracle grow sprayer you attach to the water hose. I filled it 1/3 full of Bromide and spent bath chips that desolved in water in another bottle. I strained the liquid soap and mixed it with the bromide and put it in the sprayer and literally painted my house with it. That where those bashtards were building their nests. (Under the eves) I've been doing this every year in early spring when I start seeing the first wasps searching for nesting areas, and again in mid Summer. They won't build a nest where I've sprayed this mix. You can very lightly spray your plants and lawn with it too and it won't harm them. I've had some pretty desent success with it so far. Two years in a row, no serious issues with those assholes. I still see a few fly around, but no nesting or swarms. Side note:I don't spray around my honey bee hives or my veggie plants when they are blooming.
Remember what Einstein said:
“I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.”
