Earlier this season, an invasion of ants came flooding into our mud room. They came in two by two, three by three, and eventually just in a big army. They set up shop in some gardening equipment I’d meant to put away but forgotten about. Most people’s first reaction would be to get ant killer from the store. Just a couple minutes of spraying would kill them and keep them from coming back.But spraying them wasn’t on my mind at all.Did you know that over 95% of the insects aren’t really pests? That means that the great majority of creepy crawlies we swat, squash and flush are actually beneficial.
