See, this is why I have to stay in the safety of this forum. When the first answer to caterpillars is pesticide, I cringe.
But I'm glad so many other members jumped in and said, "Wait! Get an ID first!"
I'm not totally organic or anything. I have wasp spray for the paper wasps and I have fire ant killer because those things freaking hurt! But I know what they are before I kill them. Moderation, folks. It does us well in most areas of life.
I'll have some pictures later, but it's been a rainy day here and nap time is calling. Thunder woke me up several times last night so Mother Nature owes me.
