I have a jalapeno plant that had several peppers one day and only a few the next. Those few dwindled down to one lonely pepper.

I have an enclosed backyard so I don't think it's a hungry human neighbor but I can't imagine what animal would come back for seconds and leave nothing behind -- no discarded pepper, no broken plants, nothing.

I'm ok with a few less jalapenos but I'm worried about my bell peppers.

Has anyone been through this? Who could the culprit be?
