Snakes are specialized animals and in general are beneficial animals, playing an important role in our environment. Most snakes are non-poisonous and help control rodent and insect populations. In Texas, only rattlesnakes, copperheads, cottonmouths, and coral snakes are poisonous and should be avoided.

That being said, if the snakes are too close for comfort, removing their shelter is one of the most effec­tive ways of discouraging them.  Eliminating rock piles, brush piles, tall grass, etc., which are inviting cover for snakes, will likely cause snakes to seek a more suitable habitat. Lumber, wood piles and other debris around the home should be stored at least 18 inches off the ground. Reducing or eliminating their food source (insects, rodents, etc.) is another way to encourage snakes to go elsewhere.

There are currently no toxicants or fumigants registered for the control of snakes. Registered commercial repellents are available for some spe­cies of snakes and should be used according to the label. None have been proven consistently effective.
