Rattlesnakes in or Under the House

Do Rattlesnakes Den under Houses?

Whether searching for prey or looking for an escape from the heat, a rattlesnake will hunt or den in any quiet, shady spot. This includes areas under decks and porches as well as basements and crawl spaces. Properties with rodent infestations are far more likely to have rattlesnakes under the house.

How Do Rattlesnakes Get in Houses?

Unlike most pests, a rattlesnake in the house doesn't gain entry by climbing or digging. Snakes get inside homes through holes in the foundation near the ground. Baby rattlers are often small enough to slip through the gaps under a door.

Prevention & Exclusion

Rodents and other small prey are the main reasons why rattlesnakes go under homes. Residents should make sure to keep properties clear of rats and mice that lure rattlesnakes under the house.

Repairing ground-level foundation cracks will help prevent rattlesnakes from entering a home. Trimming tall weeds and grass on a regular basis, in addition to clearing out debris from under porches and decks, will also remove hiding places for both snakes and their prey.

Control & Removal

Residents should never attempt to handle or catch rattlesnakes in the home. These reptiles bite quickly, and their venom can be fatal, especially for those who have an allergic reaction.

Upon finding a rattlesnake in the house, immediately move all children and pets away from the area. If possible, close off the room where the snake is located. Call the wildlife experts at Critter Control for rattlesnake removal.
