As the weather cools during the shift from summer to autumn, some reptiles may begin to approach homes, according to researchers at the University of Virginia. Once inside, these animals often look for warm, dark, and rarely visited areas. This is why people may occasionally find a snake behind a refrigerator, where the motor generates consistent heat and where small prey also tend to move around. Snakes are ectothermic, meaning they do not generate their own body heat. As temperatures drop, their bodies slow down, and they naturally seek out warmer areas to stay active. The back of a refrigerator meets several of these needs. The compressor continuously emits heat, while the area near the wall remains dark, narrow, and rarely disturbed. This location can also provide food. Mice often use the same hidden spaces behind furniture and appliances. Therefore, the combination of heat, quiet, and the possibility of prey makes this part of the kitchen an appealing hiding spot for a snake. Most of the time, the snake is simply looking for a place to hide. Snakes typically do not attack humans without reason and prefer to escape when possible. However, identifying the snake is important to assess any risk of a bite, which can be difficult when it curls up in the shadows of an appliance, coiled and still. When in doubt, it is best to treat any snake as potentially dangerous and keep a safe distance. For safety, it is never advisable to blindly reach behind a refrigerator. The American Centers for Disease Control and Prevention, or CDC, recommend not attempting to catch the snake yourself and instead contacting a trained professional. Using a remote-controlled light can help spot the snake without getting too close or cornering it, as a cornered snake may become defensive. First, move children and pets away from the room, then provide the snake with a clear path to escape. To prevent it from returning, seal cracks in the foundation, pipe openings, ventilation grates, and the bottom of doors. An opening as small as a few millimeters can be enough for a snake to enter. Outside, clearing wood piles, dead leaves, and debris removes nearby shelters and the rodents that snakes feed on. Keeping the lawn short also eliminates tall grass where snakes might hide along walls. The next time temperatures drop, the snake will find fewer welcoming spots around the house, reducing its chances of entering.
