If you're a homeowner with a deck, you're likely aware of the potential for unwanted animal visitors. From raccoons to squirrels, animals can cause damage and create unsanitary conditions. Fortunately, there are several DIY methods to keep animals out from under your deck. Let's explore some effective and eco-friendly solutions.

Before we dive into the DIY methods, it's essential to understand why animals are attracted to your deck. Animals seek shelter, food, and nesting sites. Your deck might be providing one or more of these, making it an attractive spot for them. By addressing these factors, you can effectively animal-proof your deck.

Exclusion Methods
Exclusion methods involve creating barriers to prevent animals from accessing your deck in the first place. These are usually the most effective and humane ways to keep animals out.

Exclusion methods require a good understanding of the animals you're trying to keep out. Different animals have different behaviors and physical abilities, so your strategy should be tailored to the specific critters you're dealing with.
Sealing Entry Points

Animals can squeeze through incredibly small spaces. To keep them out, you need to seal all potential entry points under your deck. This includes gaps between the deck and the house, spaces between boards, and holes created by previous animal inhabitants.
Use hardware cloth, metal flashing, or foam sealant to close these gaps. Hardware cloth is a durable, animal-proof option, but it's more expensive and time-consuming to install. Metal flashing is cheaper and easier to install, but it may not be as durable. Foam sealant is the easiest to apply but may not last as long and can be less effective against determined animals.
Installing Motion-Activated Lighting and Sound Devices

Many animals, such as raccoons and opossums, are nocturnal and prefer to avoid human activity. Motion-activated lighting and sound devices can deter them by creating a disturbance in their environment.
These devices are easy to install and can be found at most hardware stores. However, they may not be effective against all animals. Some, like squirrels and birds, are less sensitive to light and noise and may still attempt to access your deck.
Deterrent Methods

Deterrent methods aim to make your deck less attractive to animals by creating an unpleasant environment for them. While these methods can be effective, they may not be as reliable as exclusion methods and may need to be reapplied regularly.
Deterrent methods are typically easier to implement than exclusion methods, but they require more maintenance to ensure their effectiveness.




















Using Natural Repellents
Natural repellents can be an effective and eco-friendly way to deter animals from your deck. These repellents work by creating an unpleasant scent or taste that animals associate with your deck.
Some common natural repellents include garlic, hot peppers, and predator urine. You can create a repellent spray by mixing these ingredients with water and spraying it around the perimeter of your deck. However, keep in mind that natural repellents may not be as effective as commercial ones and may need to be reapplied more frequently.
Installing Physical Barriers
Physical barriers can deter animals by making it difficult or impossible for them to access your deck. These barriers can be as simple as placing hardware cloth over the space under your deck or as complex as installing a fence around your entire yard.
Physical barriers are typically more effective than other deterrent methods, but they can also be more expensive and time-consuming to install. They may also affect the appearance of your yard, so it's essential to choose a barrier that fits with your landscaping.
In conclusion, keeping animals out from under your deck requires a combination of exclusion and deterrent methods. By sealing entry points, using natural repellents, and installing physical barriers, you can create an unwelcoming environment for animals. Regular maintenance and a proactive approach are key to keeping your deck animal-free. So, don't wait, start animal-proofing your deck today and enjoy your outdoor space without unwanted visitors!
