I have successfully stopped my slug problem on my beautiful hosta garden!! A heavy load of sweet gum balls as mulch. But now I have these uninvited guests consuming the leaves. Can they be sprayed or dusted now?
From the photo it appears they are lady bugs and lady bug larvae--that is the small alligator looking creature in the picture you sent. They should not be cutting holes in the leaves, but feeding on aphids that may be present. Lady bugs are beneficial insects in all stages, and don't harm plants. Look closely to make sure you have no slugs hiding or possibly caterpillars feeding. There are numerous insects that can feed on hostas, but the lady bugs aren’t the culprit.
