As with all your wild urban neighbors, to discourage snakes you will need to address possible areas used for shelter and food sources.
- Shelter could be a wood/brush pile, stack of building materials, over grown landscaping, access under or through cracks in a deck or out building, compost/mulch. Modifications to prevent access of these potential shelters will make your yard less inviting.
- Inspect your home from the ground level around your foundation and any plumbing. Be sure all plumbing openings have been secured in your laundry room, bath room and kitchen.
- Removal of food sources for rodents and insects, such as bird feeders, uncontained garbage, pet food left out, or food items stored in a garage or out building, or waste in a compost pile.
- Embrace the benefits of some of your mammal wild neighbors such as the opossum and skunk. Both are immune to the venom of poisonous snakes and actively hunt and eat snakes. Remember keeping a balance of predator and prey keeps our environments balanced.
