Snakes, whether they are poisonous or not, are often unwelcome guests underneath homes and in crawlspaces. Snakes prefer dark, shady and moist areas, and these spots are ideal spots to find these reptiles. In addition, rodents, one of the main food sources of reptiles, can also be found in these same locations. While the vast majority of snakes are harmless, poisonous varieties may pose a health risk to residents. Snakes should be removed when found, and their points of entry should be closed to prevent them from coming back. While there is no "snake repellent," certain measures can be taken to discourage snakes from returning.
Things You'll Need
- Hardware mesh cloth
- Wire cutters
Remove all snakes from underneath the house. If you believe that you may have poisonous snakes underneath your home, call in a professional to have them removed. You don't want to go to work sealing your home, only to find that you have locked a few underneath the house.
Inspect the entire foundation and outside of the home. Look for small cracks, holes and any other place where a snake may enter. Keep in mind that even tiny entry points can still be used by snakes. Place a marker or a flag near all of these points.
Seal up small cracks and holes. Caulk is typically sufficient to seal off these entry points, so long as the crack is small. Pump the caulk into the crack or small hole and allow it at least 24 hours to dry. Sand it smooth if you prefer, or leave it as is.
Use mesh screen to block off larger areas. If you have larger holes, seal these these entrance points with a fine hardware mesh. You can purchase the mesh at local hardware stores. Find a mesh that has holes no larger than 1/4 inch around. Place the mesh over the hole and grout over the sides to secure it in place. Allow this at least 24 hours to dry.
Discourage snakes from investigating your home. Keep weeds and grass away from the side of your house and away from buildings in the yard. Avoid planting ground covering or dense plants near the side of your home. Snakes find this environment very inviting.
