They feed on grubs, earthworms, and other insects. Skunks are omnivorous, feeding on insects, small rodents, fruits, berries, corn and other garden vegetables, and garbage. Once their food supply is gone, moles and skunks will often leave the area to seek more abundance food supplies. They also become a nuisance by crawling onto walks, porches, walls, and into cellars and basements, leaving behind a thick slime trail that remains visible for many days. Working mostly at night, slugs and snails will return many times to the current best feeding area in your garden, using the slime trails they leave as a handy trail marker for each return trip.
Moisture is critical to their survival.
When conditions are dry they go dormant, becoming active again only when moisture is available. Although there are several hundred species of snails, only a few do major garden damage. The familiar and extremely destructive brown garden snail was brought here from Europe. The snail's shell is really an outside skeleton that grows as the snail grows. The head contains a tongue with 21,000 teeth used to saw plants into bits before devouring them.
