We don't know where you are to know what kind of weather you might be experiencing - might help in identifying your problem. Can you add your zone, state to your sign in line?

If you don't find any thing checking in the daytime, go back out at night with a flashlight and check again for the night feeders. Begin shortly after dusk, return a second time if you don't find anything then. It's amazing what's going on in our gardens after dark. Very few things other than occasional deer will be found in my garden in daylight hours, while slugs, snails, climbing cutworms, earwigs. adult weevils, show up much later :)
