Put the worst tasting beer you can find in this trap and let the slugs and even snails come. Top lifts off to easily clean out after use. You may be able to use it for rolly polly control. Add some diatomaceous earth to the tray and then put fruit on top of that (orange slices and strawberries work well). The cover is helps to keep flying insects out and rain from diluting your solution you add to the trap.
