Squirrels are often seen as cute, harmless creatures that scurry around parks and backyards. However, some people believe these critters are evil and threaten humans and other wildlife. While this may seem like an extreme view, there are several reasons why squirrels have earned this reputation.

For starters, squirrels are notorious for raiding bird feeders and gardens, causing damage, and stealing food. They also chew through electrical wires, leading to power outages and even house fires.

In addition, squirrels can carry diseases such as Lyme disease and salmonella, which can be transmitted to humans and pets.

Despite their seemingly harmless appearance, squirrels can also be aggressive and territorial. They have been known to attack humans and other animals, especially during mating season or when they feel threatened.

These attacks can result in serious injuries, mainly if the squirrel carries a disease.


Squirrels Carry Diseases


Squirrels have been known to carry a variety of diseases that can be harmful to humans. One of the most well-known diseases squirrels carries is the bubonic plague, transmitted by fleas that infest the rodents. While the bubonic plague is rare in the United States, cases have been reported in recent years.

Squirrels can also carry other diseases, such as Lyme disease, salmonella, and tularemia. Lyme disease is transmitted by ticks that feed on infected squirrels, while salmonella and tularemia are bacterial infections that can be contracted by handling or consuming contaminated squirrel meat.

Additionally, squirrels can carry mites and other parasites that can cause skin irritation and other health problems.

Taking precautions when dealing with squirrels is essential to avoid contracting any of these diseases. This includes avoiding contact with sick or dead squirrels, wearing gloves when handling squirrels or their droppings, and thoroughly cooking any squirrel meat before consuming it.


Squirrels Cause Property Damage


Squirrels may look cute and harmless but can cause significant property damage. This section will explore two ways squirrels can cause property damage: chewing on wires and wood and stealing bird feed.


Chewing on Wires and Wood


Squirrels have the instinct to chew on things, and unfortunately, this can lead to costly damage to homes and other structures. One of the most common things that squirrel chew on is wires.

This can be dangerous, as it can cause electrical shorts and even fires. In addition, squirrels have been known to chew through the insulation on wires, exposing the metal underneath. This can result in a short circuit, which can cause a fire.

In addition to wires, squirrels also like to chew on wood. This can be a problem if they start chewing on the wood of your home or other structures on your property. Over time, this can weaken the wood and cause structural damage.

Squirrels have been known to chew through siding, trim, and even the wooden supports of porches and decks.


Stealing Bird Feed


Another way that squirrels can cause property damage is by stealing bird feed. Many enjoy feeding birds in their yards, but squirrels can quickly become problematic. Squirrels are notorious for raiding bird feeders, which can cause damage.

They may chew through the plastic or metal of the feeder, causing it to break or become unusable. They may also spill seeds all over the ground, attracting other pests like mice and rats.

Though squirrels may seem harmless, they can cause significant property damage. Homeowners should prevent squirrels from chewing on wires and wood and stealing bird feed.

This may include using squirrel-proof bird feeders, sealing up any holes or gaps in the home’s exterior, and trimming back any branches that may be providing squirrels access to the roof or other areas of the home.


Squirrels are Aggressive


Squirrels are often seen as cute and harmless animals but can be surprisingly aggressive. This section will explore two ways squirrels can be fierce: attacking humans and pets and competing with native species.


Attacking Humans and Pets


While it is rare for squirrels to attack humans, it does happen. Squirrels can become aggressive when they feel threatened or cornered. They may also attack if they are defending their young or their territory. In some cases, squirrels have been known to attack pets, such as dogs and cats.

When a squirrel attacks, it may bite or scratch its victim. In addition, squirrels can carry diseases like rabies and tularemia, so it is essential to seek medical attention if you are bitten or scratched by a squirrel.

To avoid being attacked by a squirrel, keeping your distance and avoiding approaching or cornering them is best.


Competing with Native Species


Squirrels are not native to all parts of the world; in some areas, they can compete with native species for resources.

For example, in the United States, gray squirrels have been introduced to areas where they did not exist. As a result, these squirrels can outcompete native species like the red squirrel for food and habitat.

Additionally, squirrels can damage trees by chewing on bark and branches. This can harm the trees and make them more vulnerable to disease and insect infestations. In some cases, squirrels have even caused power outages by chewing on electrical wires.

Overall, while squirrels may seem harmless, they can be surprisingly aggressive and can cause damage to both humans and native species. Therefore, it is essential to be aware of these risks and avoid conflicts with squirrels.




While squirrels may seem like cute and harmless creatures, the evidence presented in this article suggests otherwise; through their destructive behavior, the spread of diseases, and the disruption of ecosystems, squirrels have proven to be a menace to humans and wildlife alike.

It is essential to protect oneself and property from these furry friends, such as sealing up entry points and using squirrel-proof bird feeders. Additionally, efforts should be made to control squirrel populations in areas where they pose a threat to native species and habitats.

Despite their negative impact, it is essential to remember that squirrels are still a part of the natural world and have a role in the ecosystem. However, it is up to humans to find a balance between coexisting with these creatures and protecting ourselves and our environment from their harmful effects.
