Homemade Squirrel Repellent for Trees


Although watching squirrels frolic in your yard and climb trees can be pleasurable, these innocent-looking furry animals can wreak havoc within days. Not only can they strip the bark off trees, squirrels use higher branches to gain access to attics where they nest young ones. Although various types of repellents are available to deter squirrels, make one at home using hot peppers. Capsaicin in the peppers irritates the squirrels, driving them away from your property without harming them.

Step 1

Pour a gallon of water in a large metal container. Replace the lid on the container and bring it to a boil on the stove. Allow it to simmer while you prepare the garlic.

Step 2

Separate a garlic bulb into cloves and place on a table. Peel cloves and finely chop or mince before adding them into a small bowl. Add the chopped garlic to the water, put the lid back on and stir gently. Continue to simmer for another 10 minutes.

Step 3

Add 2 tbsps. of ground cayenne pepper to the water and stir gently. Scrape the sides of the container to prevent the pepper from sticking. Turn off the heat after a few minutes.

Step 4

Add 2 tbsps. of habanero pepper sauce and 2 tbsps. of Tabasco pepper sauce to the container. Mix well with a wooden spoon. Cover the container and keep aside to cool the mixture. Stir occasionally.

Step 5

Add 2 tbsp. mild dishwashing liquid to the cooled mixture and stir gently. Avoid vigorous stirring that could cause the liquid to froth.

Step 6

Line a fine mesh sieve with a 12-by-12-inch square piece of cheesecloth. Rest it directly over the opening of another clean gallon container. Carefully lift and tilt the container containing the mixture and pour through the sieve. Unsaturated cayenne or garlic will collect in the sieve.

Step 7

Pour the mixture into a spray bottle. Replace the lid tightly and spray liberally over flowerbeds, around bird feeders and over tree trunks to deter squirrels. Store the spray bottle in a cool, dry place until needed.
