Mixing with various ingredients makes it a colony killer. Be it wasps, hornets or ants. Here's the recipe I use: 4 egg yolks, 1/2 sugar, 1/2 boric acid. It turns out a putty-like substance that can be placed anywhere. Follow these proportions and you will be happy. Too much boric acid and they won't eat it. Reduce or increase the entire recipe as needed.
