How to Keep Squirrels Out of Cedar Siding

Squirrels often become a nuisance in residential areas because they damage building materials such as electrical wiring, siding and insulation. They also damage plants in the garden and frighten birds at bird feeders. Squirrels usually make their nests in natural openings in trees, in man-made squirrel boxes or in leaf nests. However, they can get into your house and build their nests in your attic. They usually forage for food fairly close to the site of their nests. Various methods can help you remove squirrels from your cedar siding.

Squirrels cause gnawing damage to cedar siding.
  1. Place peanut butter, orange, apple or nutmeats in a live trap or cage trap at least 9 inches by 9 inches by 24 inches. Place the trap about 6 inches off the ground in an area where you often see squirrels. This attracts squirrels hiding in your home when they go out to forage for food. When you catch a squirrel, release it outside.

  2. Install electric lights and scatter mothballs in areas where squirrels hide inside the home. This temporarily keeps squirrels away while you make the area inhospitable to squirrels.

  3. Apply a taste repellent containing thiram to make the cedar siding taste unpleasant to squirrels and reduce their gnawing. If you can't find such a repellent, replace it with a mixture of 1 pound of copper naphthenate and 2-1/2 quarts of mineral spirits, linseed oil or shingle stain.

  4. Repair the rotten or damaged areas in the cedar siding. Also cover other openings, such as the inside of attic vents, using 1/2-inch hardware cloth.

  5. Get plastic pipe sections, each about 2 to 3 inches in diameter and 2 feet in length. Slit the pipe lengthwise, spread it open, and lay it over wires that squirrels use to travel. When a squirrel steps on the wire, the pipe rotates, making the squirrel lose its balance.

  6. Remove tree branches that hang over your roof to prevent squirrels from jumping onto the building from them.
