Squirrels look cute and playful, but they can be a big problem. They chew on things and can cause a lot of damage to your home. You might be wondering how to stop them from using your house as their personal snack bar. This guide will teach you how to keep squirrels away and protect your home.

Introduction to Squirrel Chewing Behavior

Squirrels often chew to keep their teeth sharp. They'll gnaw on wood, plastic, and even wires. Especially, they target areas around homes like siding and attic vents. This habit helps them find nesting materials and explore their world.

Squirrel chewing can lead to big problems. It can cause damage to houses, let in water, and start fires. Knowing why squirrels chew helps us stop them from damaging our homes.

Why do Squirrels Chew

Squirrels chew a lot to maintain their teeth's sharpness. Their teeth always grow. Chewing wears their teeth down, making them good for finding food and surviving. They chew on wood, plastic, and wires because of this need.

  • Wood: Siding, fascia boards, and attic vents are common targets for squirrels.
  • Plastic: You'll find squirrels chewing on plastic furniture and containers too.
  • Electrical Wires: This can be dangerous, leading to fire risks and expensive fixes.

Chewing is not just about teeth for squirrels. They also chew to gather nesting materials. These are used for their dens and to stay warm.

Types of Squirrel Damage

Squirrel chewing can cause many problems, some very costly. It can lead to structural, water, and electrical issues as well as health concerns. This can make daily life difficult for homeowners.

  1. Structural damage: Homes can be seriously affected by squirrel chewing on wood.
  2. Water damage: Entry points created by squirrels can let in water, causing more problems.
  3. Electrical hazards: Chewed wires are a fire risk and need professional attention.
  4. Contamination: Squirrels may spread diseases that affect people and pets.
  5. Nuisance: Chewing on outdoor items and furniture can be a major annoyance for homeowners.

How to Keep Squirrels from Chewing on House

Keeping squirrels away from your house can be tough. Yet, you can do it with the right methods. To start, make your home less inviting and hard to get into. Cut branches that squirrels could use to climb onto your roof or walls.

It's also important to close up any spots where squirrels might sneak in. Cover gaps and openings with strong wire mesh. Since squirrels are smart, you need to check carefully and seal every possible entry.

  • Trim tree branches that are within 6-8 feet of your home to eliminate easy access points.
  • Use hardware cloth or other durable mesh to seal off gaps, vents, and holes that could allow squirrels to enter.
  • Pay close attention to potential entry points, as squirrels can fit through holes as small as a quarter.

To keep squirrels away, your yard's setup matters too. Keep plants and bushes near your home neat. Get rid of any spots where squirrels could hide. Also, plant flowers and herbs like geraniums, mint, and rosemary. These can help keep squirrels off.

By using these tips, you can stop squirrels from damaging your home. Be smart and prevent squirrels before they become a problem.

Using Taste Repellents to Deter Squirrels

One good way to keep squirrels away is by using taste repellents. They usually have capsaicin - the spicy part in chili peppers. You can put these on things that squirrels might chew, like wood or wires. Their strong taste makes the squirrels not want to chew there anymore. It's friendly to the environment too.

These repellents make squirrels avoid places by making those spots taste bad. The capsaicin makes the areas unappealing to squirrels. So, they won't chew on your wooden decks or wires. It's a safe choice for people wanting to protect their homes without hurting the squirrels.

It's key to keep reapplying the repellent. This is important after it rains. Doing this consistently keeps squirrel problems away from your home. Squirrel repellent can stay useful for a long time with the right care.

Besides capsaicin-based options, there are other things that work too. For example, hot sauce, garlic, or predator urine. These can also stop squirrels from causing damage. They offer more ways to keep your place safe from chew marks and other harm.

Using taste repellents and these other methods together is a good plan. It helps protect your home from squirrels. Just remember, keep checking and reapplying as necessary. This will keep your home and yard safe and pleasant.

Applying Physical Barriers and Traps

Instead of taste repellents, you can use physical barriers and traps to keep squirrels away. A sticky substance on surfaces stops squirrels from climbing. You can put up live traps to catch problem squirrels, which is part of a bigger strategy to keep them out.

Many people use wire mesh to cover gardens and stop squirrels. It's a fence that makes it hard for them to get in. This type of fencing costs between $10 and $45 based on its size and quality.

Putting metal flashing or aluminum sheeting at the base of trees or structures helps too. Squirrels can't easily climb this slippery stuff. These materials are priced around $5 to $30, depending on what you need.

Combining barriers, traps, and taste repellents makes a strong defense. This strategy physically blocks squirrels. It helps keep your home and garden safe from these bothersome animals.


Squirrels can cause a lot of trouble and damage. But, there are many ways to keep them away from our homes. Homeowners can use different strategies to scare off squirrels and protect their homes from harm.

To prevent squirrel chewing, it's important to cut back tree branches and seal off any ways they can get in. You can also use things they don't like to taste and set up barriers. These methods, along with using scent and traps, are effective in keeping squirrels out.

Being ready to handle squirrels can save homeowners a lot of time, money, and stress. With the right steps, we can make sure our homes are safe from these pests. This way, we can all live happily without worrying about our property.
