Well I found out what was eating my mint. I found three small caterpillars this morning. I wondered how big the bugger was bc not much was being eaten each day but I could tell something was nibbling on it. Out of spite I was cutting the mint totally back just so whatever it was wouldn't have anything to eat.....and I touched one with my bare hand by accident! At least it was a small one. I left two as an offering for the black widow. The last one for the birds. Didn't see the black widow last night. I bet she died already.
