Yea I have these stupid little grasshopper looking things that love to sit up there and munch on them in the evening time.
It's the only bug I have any dealing with because they can hop onto it since I use bug killer grains on my soil once a pot(always have in my garden plants, and not toxic either since it doesn't get absorbed by roots but can't use on things such as peas or cabbage when sprouting) and sven dust around the base to prevent anything from crawling on it. But just little grasshopper type things and I have noticed they are leaving little slug type spots, but not slugs.
