Effective Deck Animal Barriers: What to Use at the Bottom

By Amanda LewisApril 19, 2026

Are you tired of uninvited guests like raccoons, skunks, or even deer invading your deck space? While fencing might be the first solution that comes to mind, it's not always the most practical or aesthetically pleasing option. So, what can you put around the bottom of your deck to keep animals out? Let's explore some effective, eco-friendly, and visually appealing solutions.

Before we dive into the methods, it's crucial to understand that each animal has unique behaviors and preferences. Therefore, a one-size-fits-all solution may not exist. However, by combining a few strategies, you can create a robust barrier that respects your deck's surroundings while keeping unwanted visitors at bay.

Natural Repellents and Deterrents

One of the gentlest ways to keep animals away is by using natural repellents and deterrents. These solutions leverage plants, scents, or sounds that animals naturally avoid.

For instance, certain plants like lavender, mint, and lemongrass are known to repel pests. You can plant them in pots around your deck or create a living barrier along the perimeter. Similarly, strong-smelling substances like garlic, hot peppers, and even human hair can deter animals. Just remember to replace these repellents regularly, as their effectiveness fades over time.

Ultrasonic Pest Repellers

Ultrasonic pest repellers emit high-frequency sounds inaudible to humans but unpleasant to animals. These devices can be solar-powered or plugged into an outlet, making them an eco-friendly and low-maintenance option. However, their effectiveness can be limited by factors like weather conditions and the specific animals you're targeting.

Moreover, some animals may eventually get used to the sound, reducing its deterrent effect over time. To mitigate this, consider using repellers that emit varying frequencies and sounds, or combine them with other methods for better results.

Physical Barriers

When dealing with larger animals or persistent intruders, natural repellents might not suffice. In such cases, installing physical barriers can provide a more reliable solution. These barriers can be discreet, blending seamlessly with your deck's design while keeping animals out.

One option is to install a low fence or a lattice around the deck's perimeter. You can choose materials that complement your deck's aesthetics, such as wood, vinyl, or composite. Alternatively, you can use hardware cloth or chicken wire to create a sturdy barrier that's less visible. Ensure the barrier extends at least a foot underground to prevent burrowing animals from sneaking underneath.

Motion-Activated Devices

Motion-activated devices can provide an extra layer of protection, especially when used in conjunction with other methods. These devices can be solar-powered or plugged into an outlet, making them an eco-friendly and low-maintenance option.

Motion-activated sprinklers, for example, can startle and deter animals by spraying them with water when they approach your deck. Similarly, motion-activated lights can illuminate the area, making it less appealing to nocturnal creatures. You can also combine these devices with ultrasonic repellers for added effectiveness.

Decks with Built-in Animal-Proofing

If you're planning to build a new deck or replace an existing one, consider incorporating animal-proofing features into the design. For instance, you can install a solid skirting around the deck's perimeter, preventing animals from accessing the underneath area. Alternatively, you can build a deck with a raised foundation, making it difficult for animals to climb underneath.

Additionally, you can opt for materials that are resistant to animal damage, such as composite or vinyl. These materials are not only durable but also require minimal maintenance, making them a practical choice for decks in areas with high animal activity.

In conclusion, keeping animals out of your deck space requires a multi-faceted approach. By combining natural repellents, physical barriers, and motion-activated devices, you can create an effective and eco-friendly deterrent system. Always remember that the best solution depends on your specific situation, so don't hesitate to experiment with different methods until you find the perfect combination. Happy decking!
