Pill bugs and Sow bugs, also known as rollie pollies, because of their ability to roll up in a tight ball, can be a real nuisance to homeowners. Both bugs feed on decaying plant material and unless very numerous will do very little damage. We will get calls from homeowners who say hundreds of these guys showed up almost overnight. There are few other insects that eat these guys due to a bad secretion from their glands that makes them very distasteful. We get more calls on Pill Bugs in very wet seasons, when it gets hot they take refuge in the soil to wait until the rains come back. A simple residual pesticide takes care of these guys.
