Are Squirrels Dangerous? (PROTECTING Property, Children, Pets, and Garden)

Squirrels are incredibly fascinating creatures, known for their playful antics and remarkable acrobatics. However, beneath their adorable exterior lies a potential threat to your property. Are squirrels dangerous? While they usually don’t pose direct harm to humans, their chewing habits can wreak havoc on your home, garden, pets, and, in extremely rare cases, even children. In this blog post, we will explore the extent of the damage squirrels can cause and discuss effective strategies to protect yourself and your property from these critters.

The main danger posed by squirrels is towards your house and garden. Squirrels can pose a threat to property due to their natural instinct to chew. Their incessant gnawing can damage structures, including electrical wiring, and create potential fire hazards. While squirrels might not be directly dangerous to humans, their propensity for causing structural harm cannot be overlooked, making it essential for homeowners to take preventive measures to protect their property from these creatures.

Are Squirrels Dangerous?

Squirrels, being small creatures, are not typically dangerous to humans or larger animals. However, in certain circumstances, squirrels can pose some risks. Squirrels can potentially be dangerous for:

  • Other Squirrels: Squirrels can exhibit aggressive behavior towards each other, especially during territorial disputes or competition for resources like food and nesting sites. These conflicts can lead to bites, scratches, or injuries.
  • Young Children: Although rare, there have been instances where squirrels have bitten or scratched young children. This is usually a result of the child inadvertently startling or provoking the squirrel, such as trying to grab or chase it. Supervision around squirrels is advisable to prevent any potential harm.
  • Pets: Squirrels may alarm or annoy pets, particularly dogs or cats that have a strong prey drive. This can lead to high-energy chases or confrontations, which can result in scratches, bites, or other injuries. Additionally, squirrels may carry parasites that can be transmitted to pets.
  • Gardeners: Squirrels are known for their love of gardens, and their fondness for digging and foraging can cause damage to plants, flowers, and crops. They may also raid bird feeders or eat fruits and vegetables from gardens, which can be a nuisance for gardeners.
  • Homeowners: Squirrels can enter homes through small gaps or openings in roofs or walls, seeking shelter or nesting sites. Once inside, they may cause damage by chewing on electrical wires, insulation, or stored belongings. This can lead to potential fire hazards or costly repairs.
  • Aggressive Squirrels: In certain circumstances, squirrels may exhibit unusually aggressive behavior. This can happen if a squirrel is injured, sick, or feels extremely threatened. An aggressive squirrel may bite or scratch if it perceives humans or animals as a threat to its safety.
  • Vehicle Owners: Squirrels occasionally cause damage to vehicles by chewing on wiring or nesting in engine compartments. This can lead to vehicle malfunctions, resulting in costly repairs or inconvenience for the owners.

It is important to note that while some risks exist, cases of squirrels causing harm or actual danger are relatively rare. Taking preventive measures, practicing caution around squirrels, and avoiding situations that may provoke them can help minimize any potential issues.

Overview of Squirrel Behavior

Squirrels are known for their agile and playful nature. They are curious creatures that love to explore their surroundings. They are also exceptional climbers, thanks to their sharp claws and strong hind legs. Squirrels are most active during the day, and they thrive in wooded areas or places with ample food sources.

One of the key behaviors that make squirrels a potential threat to your property is their constant need to chew. Their teeth continue to grow throughout their lives, and chewing helps keep them in check. Unfortunately, this instinct can lead squirrels to wreak havoc on your home and possessions.

Potential Dangers Caused by Squirrels

Humans and pets

In everyday encounters, squirrels seldom pose a threat to humans or pets. They typically remain cautious in their interactions and tend to flee when approached. Often, they are more afraid of humans than vice versa. Squirrels are naturally curious and may approach humans in search of food if they have been habituated to human presence.

While squirrels themselves may not be dangerous, some situations can lead to potential harm. For instance, if a squirrel feels cornered, threatened, or provoked, it may attempt to defend itself by scratching or biting. This is a rare occurrence, but it can happen if a squirrel feels extremely threatened or is protecting its young.


Moreover, squirrels are known for their gnawing habits. They have sharp teeth that grow continuously throughout their lives, which they use to chew on various objects, including tree bark, nuts, and even electrical wires. This constant gnawing behavior can sometimes lead to damage to property, such as chewing through insulation, which may pose a fire risk.

In urban and suburban areas, squirrels may also get into attics or other parts of houses through small openings. While this can be a nuisance, they can potentially cause damage to structures or objects they encounter in their search for food or a suitable nesting place.

Damages to wooden structures

They frequently target wooden structures, including the eaves, fascia boards, and even the structure of your home. If left unchecked, squirrels can create openings that allow water to seep into your property, leading to costly repairs.

Damages to electrical wiring

Another major concern is their affinity for chewing through electrical wiring. This poses a serious fire hazard, as exposed wires can easily spark and ignite flammable materials. The risk of an electrical fire increases if the squirrels access crawl spaces, attics, or wall voids, where they can come into contact with wiring systems.


Squirrels can cause damage to gardens by digging up plants, flowers, and vegetables while foraging for food. They may also raid bird feeders or nibble on fruits and vegetables, leading to the loss of crops. Implementing protective measures like fencing or using squirrel-proof feeders can help mitigate garden damage.

Diseases Potentially Carried By Squirrels

It is worth mentioning that squirrels are carriers of certain diseases, including ticks, fleas, and sometimes even parasites. However, the risk of contracting these diseases from squirrels is relatively low, especially if you do not come into direct contact with them or their droppings.

Signs of Squirrel Presence

Identifying the signs of squirrel presence is crucial for taking timely action. Look out for chewed or gnawed areas, especially around rooflines, gutters, and wooden structures. Squirrels also leave behind droppings, which are usually small, cylindrical, and resemble pellets.

Another indicator of a squirrel infestation is the presence of nesting materials such as leaves, twigs, and shredded insulation. Additionally, squirrels are known for their chattering and scampering noises, so if you hear these sounds coming from the walls or attic, it’s a strong indication of their presence.

Prevention Methods

To safeguard your property from squirrel-inflicted harm, it is essential to employ preventive measures. Ensuring that the outer vicinity of your abode remains clear of trees, shrubs, and greenery is paramount, as they can act as conduits for squirrels to infiltrate your premises.

It is crucial to ensure that your home’s foundation remains intact by sealing any openings or cracks, as this will effectively deter squirrels from gaining entry. Additionally, it is of utmost importance to caulk any gaps surrounding the exterior windows and doors, while also firmly securing a well-fitting cap on your chimney. These precautionary measures aim to establish a formidable barrier, effectively discouraging the intrusion of squirrels into your dwelling.

Furthermore, if you have bird feeders on your property, make sure they are located at a safe distance from the exterior of your home. Squirrels are attracted to bird feeders, and having them too close to your house can increase the chances of squirrel activity near your property.

Now, let’s look more in detail to some of the most popular methods to deter squirrels!

  1. DIY approach – put on a squirrel-sized superhero cape and send them packing.
  2. Hire the squirrel whisperers – experts in all things squirrel-related.
  3. Bribe them with acorns to relocate to your neighbor’s yard.

When dealing with squirrels, it’s important to respect the legal regulations regarding wildlife control. In most areas, you are not allowed to harm or kill squirrels without the proper permits. Therefore, scaring squirrels away or using lethal methods is not recommended.

Instead, focus on peaceful coexistence and employing preventive measures to deter squirrels from your property. Ensure your actions align with local laws and regulations, promoting a harmonious balance between humans and wildlife.


So, are squirrels dangerous? Well, maybe not in the traditional sense of attacking humans or carrying deadly diseases. But, when it comes to wreaking havoc on your home, they can be quite the little troublemakers! With their constant gnawing and chewing, squirrels can cause significant damage to your property, potentially leading to fire hazards and expensive repairs. It’s important for homeowners to be aware of these mischievous creatures and take proactive steps to protect their beloved abode from squirrel-induced mayhem.

From sealing up potential entry points to implementing squirrel-proofing measures, there are numerous ways to safeguard your home against these furry troublemakers. So, don’t let those innocent-looking faces fool you! Take action and protect your property from the damaging effects of squirrels – after all, prevention is always better than a chewed-up electrical wire!
