DIY Under Deck Animal-Proofing: What to Use to Keep Critters Out

Discovering unwanted animal guests under your deck can be a frustrating experience. Not only do they cause damage, but they also pose health risks. Fortunately, there are several DIY methods to keep animals out, ensuring a peaceful and safe space beneath your deck. Let's explore some effective solutions to this common problem.

Before we delve into the DIY methods, it's crucial to understand the types of animals that might be invading your space. Common culprits include raccoons, squirrels, skunks, and rodents. Each of these animals has unique habits and preferences, which we'll consider when discussing repellent strategies.

Physical Barriers

One of the most effective ways to keep animals out is by creating a physical barrier that prevents them from entering in the first place. This approach is particularly useful for smaller animals like rodents and snakes.

To create an effective barrier, you'll need to seal off any potential entry points. This might involve installing hardware cloth or metal mesh along the bottom of your deck, ensuring that the gaps are small enough to prevent even the smallest animals from squeezing through.

Hardware Cloth

Hardware cloth is a durable, flexible material made of galvanized steel wire. It's an excellent choice for creating a barrier because it's strong enough to withstand the gnawing and scratching of even the most determined animals. Plus, it allows air and water to pass through, preventing moisture buildup beneath your deck.

To install hardware cloth, measure the area you need to cover and cut the cloth to size. Then, use staples or screws to attach it to the underside of your deck, ensuring that it's taut and secure. For added protection, you can also fold the bottom edge of the cloth outward and secure it with staples or screws, creating a lip that makes it even more difficult for animals to gain entry.

Metal Mesh

Metal mesh is another effective barrier material. It's similar to hardware cloth but has a more open weave, which can make it less durable than hardware cloth. However, it's still an excellent choice for keeping out smaller animals and is often more affordable than hardware cloth.

To install metal mesh, follow the same steps as you would for hardware cloth. Measure the area you need to cover, cut the mesh to size, and attach it to the underside of your deck using staples or screws. Again, consider folding the bottom edge outward for added protection.

Repellents and Deterrents

While physical barriers are an effective way to keep animals out, they're not always practical or aesthetically pleasing. In these cases, repellents and deterrents can be a useful alternative. These substances are designed to repel or deter animals by making the area beneath your deck less appealing.

It's essential to choose repellents and deterrents that are safe for both humans and pets. Always follow the manufacturer's instructions and reapply as directed to maintain effectiveness.

Natural Repellents

Many natural substances can be used to repel animals. These are often safer and more environmentally friendly than chemical repellents, making them an excellent choice for those who want to minimize their impact on the environment.

Some popular natural repellents include:

• Essential oils, such as peppermint, eucalyptus, and citrus, which can be diluted with water and sprayed around the perimeter of your deck.
• Garlic and hot peppers, which can be blended with water and sprayed beneath your deck or placed in strategic locations.
• Coffee grounds, which can be sprinkled around the area to deter animals like raccoons and skunks.
• Ultrasonic pest repellent devices, which emit high-pitched sounds that are inaudible to humans but repel many types of animals.

Chemical Repellents

Chemical repellents are designed to mimic the scents of predators or other animals' alarm pheromones, causing the target animals to avoid the area. These repellents are typically more potent than natural repellents and can be effective for a more extended period.

Some common chemical repellents include:

• Predator urine, such as coyote or fox urine, which can be sprayed around the perimeter of your deck.
• Capsaicin-based repellents, which use the active ingredient in hot peppers to deter animals.
• Sodium thiosulfate, a chemical that produces a scent similar to that of a predator's urine, which can be used to repel a wide range of animals.

Regularly inspecting the area beneath your deck and addressing any signs of animal activity promptly is crucial for maintaining a pest-free space. By combining physical barriers, repellents, and deterrents, you can create a multi-layered defense that keeps animals out and ensures a peaceful, safe environment beneath your deck.

Embracing a proactive approach to pest control not only protects your property but also helps maintain a harmonious relationship with the local wildlife. By understanding the habits and preferences of the animals in your area and choosing DIY methods that cater to their natural behaviors, you can create a win-win situation that keeps both you and the animals happy.
