What Does a Squirrel Chewing Look Like? 
If you’re looking for a tree to chew on, you’ll want to know what to look for when you notice a hole. You’ll often notice strips of bark and scales, shingles or decking, and in some cases, even holes. If you find holes, you’re probably a victim of squirrel heart rot, a condition where the heart of the tree becomes soft and crumbly.

Stripped tree bark
In some cases, the stripping of tree bark occurs in conjunction with the female squirrel giving birth. This is often a painful and stressful time for the female, but it is also an opportunity to find good nesting material for the young. The cambium layer is rich in nutrients and may serve as an attractive choice. If the squirrel’s behavior is consistent, the tree will survive. Branches may fall off, and the tree may eventually fall over.
Stripped tree scales
Studies have shown that the calcium levels in trees are higher in branches than in trunks. This may explain why some tree species are more susceptible to squirrel chewing. Squirrels are also known to consume the tree bark, which is made up of calcium oxalate. They can then use the calcium to build their bones. This calcium hypothesis has been put to the test by observing squirrels chewing on the bark of coniferous trees.
Stripped shingles
Squirrels are a common pest in Salt Lake City. They will destroy your garden crops, nuts, fruits, grains, bark and leaves, and will spend most of their winter time collecting food. In addition to tearing off the shingles on your roof, they will chew through the soffit, fascia and gutters of your home, and they can also chew electrical wires and insulation to create their own dens. Even worse, they can cause a fire hazard by chewing on stored items.
Stripped decking
In addition to chewing up your decking, squirrels can also cause significant damage to building structures, including your attic. Squirrels can chew through electrical lines and create a fire hazard. They will also gnaw on wooden window frames and siding. They can even uproot your plants. If you suspect squirrels are chewing on your decking, look for chew marks.
Stripped baseboards
What does a squirrel chewing look like? If you’ve noticed squirrels chewing on your baseboards, you’re probably wondering what they’re doing. If you’re not sure, they might be chewing on bark, which contains a high amount of nutrients. Or they could be chewing on wire, which may cause a fire hazard if the squirrels are using the baseboards as nesting material.
Stripped tree limbs
There are two ways for squirrels to damage trees: by stripping off the bark, or by debarking and chewing on the twig tips. Usually, twig pruning is harmless and improves canopy density. But destructive debarking can girdle a tree and cause considerable damage. In the United Kingdom, gray squirrels are now considered an invasive pest. If you notice any of these signs, contact a tree care professional to prevent further damage to your tree.
Stripped cables
When a squirrel gnaws on your cables, they can cause a lot of problems for you. Wiring in your attic is often exposed wiring can be chewed, ran across, or pawed loose. This could lead to dead circuits or a fire hazard if a live wire is chewed. Here are some ways to deal with this problem. First, cut the chewed portion off of the cord. Then, splice two cords together. Replace the damaged cord.
