A family of Tent Catterpillars have taken up residence in our apple tree. Apparently they will kill the entire tree if we don't deal with them. My summer began with a war on ants and apparently will end with a war on Catterpillars. Those apples are sour but I sure like them in a crisp! If you have had to deal with Tent Catterpillars before I would love to hear how you made them disappear.
