As an expert on squirrels, I have been observing and interacting with them for years. Sadly, I’ve seen how damaging their presence can be to trees in many cases. From stripping bark off of trunks to biting off twigs and living in holes, these cute rodents can harm trees beyond repair if not monitored carefully. In this blog post, let me explain why are squirrels harmful to trees and how to prevent damage and control infestations.

Squirrels can pose a threat to the health of our trees if they are overzealous in their activities. Stripping large amounts of bark off trees can leave them open to disease and attack from squirrels-eat-insects/”>insects, whilst gnawing twigs or building nests in trunk cavities can also cause irreparable harm. As such we must remain vigilant in scrutinizing the behavior of these critters around our greenspaces in order to protect them from undue damage.

Are Squirrels Harmful to Trees?

Squirrels are one of nature’s busiest creatures, but their curious nature and constant search for food can also leave a trail of destruction. Tree squirrels feed on flowers, fruits, seeds, cones, nuts and tree bark – they will even chew through plastic siding and vents to gain access into homes. While they usually don’t cause serious harm or permanent damage, over time these activities can reduce or eliminate their food sources, including bird feeders. They can also tear open young tree and shrub growing tips, reducing the chances of successful regrowth.

In addition to their physical damage, the presence of a large population of squirrels indicates an unbalanced ecosystem which can become a nuisance for property owners. If too many squirrels live near trees with developing nuts, they can strip off the bark and prevent the tree from receiving vital nutrients.

Overview of Damage Prevention and Control

Habitat Modification

The first step in preventing damage is to avoid creating habitats favourable to squirrels. This includes removing potential nesting sites such as tall grasses and low-growing bushes near structures. Any trees that have grown tall enough for squirrels to jump onto should be trimmed away from buildings. Installing sheet metal bands on isolated trees prevents them from stripping off bark and eating developing nuts.

Other actions include installing chimney caps and closing any external openings to buildings – however caution needs to be taken when attempting this as you don’t want to trap animals inside the home.

Exclusion

Frightening Devices

Frightening devices are another form of exclusion – these use sound or scent stimuli meant to scare away unwelcome wildlife. Specially designed plastic tubes that fit over non-electrical service wires may also hinder access to buildings by creating an extra barrier.

Repellents

Toxicants

Naphthalene is one toxicant that may discourage squirrels from entering attics or other enclosed spaces. This method requires caution due to its potential health risks – it should not be used in occupied buildings as it can cause severe distress in people.

If you’re looking to use a commercial repellent of any kind, you’ll need to get proper certification for its application as a pesticide.

Trapping and Shooting

Cage Traps

Cage traps of 5 x 5 x 18 inches in size or bigger are the best way to capture tree squirrels. These traps should use a 1/2 – 1 inch mesh, so that the critters don’t sustain any injury when they’re caught. For an even better setup, attach the cage to a tree trunk or position it atop a plywood shelf.

When placing cages for trapping squirrels, make sure that each one has about two to three inches area in front of the door needed for adequate standing room.

Body-gripping Traps

For trapping squirrels, body-gripping traps are a great choice. These traps can be discreetly placed over the entryway and secured through small drilled holes at both ends. Alternatively, tunnel traps can be used to enclose the squirrel without showing it to the public eye.

Foothold Traps

No. 0 or 1 foothold traps can trap squirrels, but they may pose a risk to non-target animals and raise questions about humaneness. This method is not recommended for capturing squirrels.

Shooting

In areas where firearms are legal, shooting is an effective way to remove squirrels from the area. A shotgun with No. 6 shot or .22 caliber rifle is suitable for this purpose, and pellet rifles (.177 caliber) can also be used in some circumstances. Make sure to check your local wildlife regulations before using this method, as it could be prohibited in some areas.

Handling of Trapped Squirrels

Relocation

If a squirrel has been trapped inside a chimney or basement, relocation is often a preferable solution instead of euthanasia. Releasing the animal on site is acceptable in these cases, provided the entrance has already been blocked off securely.

Translocation

Translocation refers to moving animals away from their original environment to another place more suitable for them. If done correctly, translocation can be beneficial for both humans and animals involved as it ensures no harm comes to either party. Before undertaking such an endeavor, it is vital to check local laws regarding sanctuary spaces or permits required for releasing animals back into nature.

Euthanasia

In certain cases, euthanasia may be necessary if injury or illness prevent a successful release of the animal in itsoriginal surroundings or if laws prohibit any other form of removal. Carbon dioxide gas environments provide quick expiration for tree squirrels in these scenarios.

Disposal

Once a squirrel has passed away due to euthanasia there must be disposal protocols followed in most areas. Depending on the jurisdiction, removing dead animals may involve contacting local authorities who can assist with burials and proper sanitation procedures.

Other Control Methods

Squirrels in Chimneys and Basements

When it comes to removing squirrels from chimneys or basements, the safest and most legal option is to call in a professional wildlife expert. It’s important to ensure the rescue site has been properly secured before releasing the animal on-site.

FAQ

What is the purpose of squirrels facing downward on trees?

Tree squirrels have the ability to descend headfirst by rotating their ankles 180 degrees. This allows them to grip the tree bark and keep from slipping on their way down. Additionally, this position helps them conserve energy when climbing and descending trees in order to survive.

What are the benefits of squirrels living in trees?

Tree squirrels are well-adapted to living in trees due to their agility and their ability to rotate their ankles. This lets them descend head-first, enabling them to better grip the tree trunk. Additionally, they can build nests in existing cover and wrap chicken wire around the base of the tree trunk, helping them insulate against cold winds during winter months. Therefore, tree squirrels are able to stay safe and warm while surviving the harsh weather conditions.

What can I do to prevent squirrels from damaging the bark of my tree?

You can protect your trees from bark stripping by squirrels by taking certain measures. These include:

Wrap chicken wire loosely around the base of the trunk.
Close external openings to buildings and other structures, so that they don’t have access.

What measures can be taken to prevent squirrels from harming trees?

Protecting trees from squirrel damage can be done by taking a few simple steps. These include:

Wrapping chicken wire around the base of the tree trunk to prevent ground squirrels from accessing the bark.
Closing external openings to buildings that squirrles may use as a means of entry.
Building nests in existing cover for the squirrels to insulate themselves during cold weather.

Conclusion

In conclusion, it is probable that squirrels can indeed be harmful to some trees. There are a variety of ways they can damage them, whether by stripping away bark, cutting off twigs, or living in tree trunks. It is important to be mindful of how squirrels interact with trees in order to prevent harm. Ultimately, the answer to the question “Are squirrels harmful to trees?” is yes.

By understanding their behavior and taking preventive measures against their potential damage, it is possible to keep your trees healthy and safe from any harm caused by squirrels. The key is to monitor for signs of activity and take action if any damage does occur. With a little effort and knowledge, you can protect your trees from any unwelcome visitors!
