To effectively keep animals out of your yard with a fence, choose a fence that anchors to the ground to deter digging. Also, consider adding a barrier below the fence to prevent burrowing. 

To make your yard less desirable to animals, eliminate food sources like a vegetable garden, and ensure your garbage cans are sealed and tamper-proof. Installing motion-activated devices like lights or sprinklers will startle animal intruders. Also, a fence won’t work well if you forget to keep gates closed and secure. If you still face persistent animal intrusion issues, contact a wildlife control expert who can offer specialized solutions.

The cheapest fence to install is likely to be a wire fence, whether it’s hog wire or chicken wire. Closely following that is something repurposed that would be free to collect, like a DIY pallet fence. Most wire fences are available in large quantities at a low cost, so they’re great for homes with a tight budget.

If you only use your gate as a pedestrian, walking through without a vehicle, you’re fine to stick with a single fence gate. If your fence opening needs to accommodate vehicles of any kind, from cars to trucks to 4-wheelers, then a double fence gate will suit the space much better and give you more freedom. 

The best wood for fence posts are redwood, cedar, and pressure-treated pine. Wood posts made from these materials will typically lasts between 15 and 30 years, depending on the specific type you choose and your local climate. With proper care and maintenance, a fence post made of these materials can withstand most weather conditions.
