Are squirrels wreaking havoc in your home? It may be time to understand the risks associated with a squirrel infestation and how to effectively deal with them. Did you know that squirrels have four front teeth that never stop growing? These rodents were introduced to America between 1876 and 1929, coinciding with the decline of our native red squirrel. While they may look adorable running around your garden, cornering a squirrel in your loft can lead to aggression, biting, and scratching, causing potential infections like Lymes Disease, Leptospirosis, and Salmonella. However, it is important to handle the situation correctly, as it is illegal to use rat poison or rat traps for squirrels, and releasing a trapped squirrel back into the wild is also against the law. Don’t risk secondary poisoning or legal trouble – leave it to the professionals.

Section 1: Introduction to Squirrel Infestations
What are squirrels?
Squirrels are small rodents that are known for their bushy tails and agile climbing abilities. They have become a common sight in urban and suburban areas, often seen scurrying across power lines and darting up trees. With their cute appearance and playful behavior, squirrels may seem harmless, but they can actually cause numerous issues when they infest homes and properties.
The impact of squirrel introduction on native red squirrels
The introduction of non-native squirrel species, such as the grey squirrel, has had a negative impact on native red squirrels. Grey squirrels, originally from America, were brought to the United Kingdom between 1876 and 1929. Since then, the population of red squirrels has significantly declined. This decline is due to competition for resources and the transmission of diseases by grey squirrels. It is important to address squirrel infestations to protect the native red squirrel population.
Section 2: Risks Associated with Squirrel Infestations
Physical damage to property
Squirrel infestations can result in significant physical damage to properties. These rodents are known to chew through various materials, including wood, insulation, and electrical wiring. Gnawing on electrical wires increases the risk of electrical fires, posing a serious hazard to both property and personal safety.
Health risks associated with squirrel bites
Squirrels are wild animals, and when they feel threatened, they may bite or scratch in self-defense. These bites can introduce harmful bacteria into the human body, potentially causing infections. It is important to seek medical attention immediately if bitten by a squirrel.
Spread of diseases
Squirrels can carry various diseases that can be transmitted to humans. One example is Lyme disease, which is transmitted through ticks that squirrels carry. Other diseases associated with squirrels include leptospirosis and salmonella. It is crucial to take precautions to prevent the spread of these diseases.
Risk of secondary poisoning
Using poison to control squirrels can lead to the risk of secondary poisoning. This occurs when the poisoned squirrel is consumed by another animal. The poison can then affect other wildlife, pets, or even humans, resulting in severe consequences. It is essential to use alternative methods of squirrel control to avoid this risk.

Section 3: Identifying Squirrel Infestations
Signs of squirrel presence
There are several signs that can indicate a squirrel infestation. Look for chewed wood or wires, as well as gnaw marks on tree trunks and branches. Squirrels also leave behind droppings that resemble small pellets. Additionally, listen for distinctive scratching or running sounds in the attic or walls, as squirrels are active during the day.
Common areas where squirrels nest
Squirrels prefer to nest in sheltered areas that provide protection and warmth. Common nesting sites include attics, chimneys, and wall voids. Outside, they may build nests in trees or create burrows in the ground. It is important to identify these nesting areas to effectively address the infestation.
Recognizing squirrel droppings
Squirrel droppings are small, cylindrical pellets that are typically dark brown or black in color. They are often found near nest areas or along pathways squirrels frequently use. Identifying and removing these droppings is essential for maintaining a clean and safe environment.
Distinctive noises made by squirrels
When squirrels are active in your home, you may hear scratching, scampering, or chewing sounds. These noises are distinct and can help identify the presence of squirrels. Pay attention to sounds coming from the attic, walls, or other areas where squirrels may be nesting.
Section 4: Prevention Methods
Sealing entry points
To prevent squirrel infestations, it is crucial to seal all possible entry points. Inspect the exterior of your home for any gaps or holes that squirrels can use to access your property. Use materials like steel wool, caulk, or wire mesh to seal these entry points effectively.
Removing potential food sources
Squirrels are attracted to food sources such as bird feeders, pet food, and improperly stored garbage. Limit their access to these food sources by using squirrel-proof bird feeders, keeping pet food indoors, and securely storing garbage in tightly sealed containers.
Trimming tree branches near buildings
Trimming tree branches that are close to buildings can prevent squirrels from easily accessing rooftops and attics. This eliminates potential entry points and makes it more difficult for squirrels to reach your home.
Using deterrents like ultrasonic devices
Ultrasonic devices emit high-frequency sound waves that are unpleasant for squirrels and can deter them from nesting in your home. Place these devices in areas where squirrel activity is observed or suspected.
Installing squirrel-proof bird feeders
Squirrel-proof bird feeders are designed with mechanisms that prevent squirrels from accessing the birdseed. These feeders typically have weight-activated perches or cages that block squirrels while allowing birds to feed safely.

Section 5: Non-lethal Removal Techniques
Using one-way exit traps
One-way exit traps are a humane method of removing squirrels from a specific area. These traps allow squirrels to exit but prevent re-entry. Once all squirrels have left, the entry point can be sealed to prevent future infestations.
Humanely evicting squirrels
Humane eviction involves creating an environment that makes it uncomfortable or unsuitable for squirrels to remain in the area. This can be achieved through tactics such as bright lights, loud noises, or the use of repellents specifically designed for squirrels.
Calling professional wildlife removal services
If squirrel infestations persist or are too large to handle on your own, it is best to call professional wildlife removal services. These experts have the knowledge, experience, and tools necessary to safely and effectively remove squirrels from your property.
Section 6: Dealing with Squirrel Nests
Identifying squirrel nests
Squirrel nests, also known as dreys, are typically constructed using leaves, twigs, and other materials. They are often found in tree branches, attic spaces, or other secluded areas. Identifying these nests is crucial for effective removal and prevention of further nesting.
Safely removing nests
When removing squirrel nests, it is important to take precautions to ensure your safety and prevent the spread of parasites or diseases. Use gloves and a mask when handling nests, and dispose of them properly following local regulations.
Preventing nest reconstruction
To prevent squirrels from rebuilding nests in previously infested areas, it is essential to thoroughly clean and disinfect the area. Additionally, implement preventive measures such as sealing entry points and removing potential nesting materials.
Section 7: Health Risks and Diseases
Lyme Disease
Squirrels can carry ticks that transmit Lyme disease to humans. This bacterial infection can cause symptoms such as fever, fatigue, and joint pain. Taking precautions such as wearing long sleeves and pants, using tick repellents, and regularly checking for ticks can help prevent Lyme disease.
Leptospirosis
Leptospirosis is a bacterial infection that can be transmitted through contact with squirrel urine or contaminated water. Symptoms include high fever, headache, muscle pain, and vomiting. Proper hygiene and avoiding contact with squirrel urine or contaminated areas can help prevent leptospirosis.
Salmonella
Squirrels can carry Salmonella bacteria, which can be transmitted through contact with their feces or by consuming contaminated food or water. Salmonella infection can cause symptoms such as diarrhea, abdominal pain, and fever. Practicing good hygiene and properly cleaning areas contaminated with squirrel droppings is crucial to prevent Salmonella.
Section 8: Legal Considerations
Illegal use of rat poison or rat traps
It is illegal to use rat poison or rat traps for squirrel control. These methods are not effective and can potentially harm other wildlife or domestic animals. Always use legal and humane methods when dealing with squirrel infestations.
Illegal release of trapped squirrels
Once squirrels have been trapped, it is illegal to release them back into the wild. Releasing trapped squirrels can spread diseases and disrupt ecosystems. Contact professional wildlife removal services to ensure proper handling and relocation of trapped squirrels.
Protection of bats in lofts
Bats are protected species in many countries, including the United Kingdom. If you suspect bat activity in your loft, it is important to handle the situation with care. Working with professionals who are knowledgeable about bat conservation and removal is crucial to avoid legal consequences.
