Snakes

Snakes are reptiles. It's true that some species are venomous, but the fact is that the majority are not. However, many people are uncomfortable around, or even have a phobia of, snakes. Because snakes are so thin, they often enter buildings and homes. Sometimes they can smell the cooler air inside, and are looking for a nice place to live. Sometimes they even smell rats in an attic, and climb up and in during a search for food.
