Squirrel-Proof Your Home: A Guide to Identifying and Preventing Squirrel Infestations 

Are you hearing scratching in your attic or walls? Don’t be surprised if the culprit is a squirrel! While often seen as cute backyard visitors, squirrels can become serious pests, especially during winter. As their mating season begins, it’s crucial to identify any existing issues and take preventative steps now to avoid a full-blown infestation later. In New England, three species are common culprits: the Eastern Gray Squirrel, the Northern Red Squirrel, and the Northern Flying Squirrel. All three have been known to invade homes, causing damage and creating unsanitary conditions. 

Identifying the Culprits: Common Squirrel Species 

Let’s get to know the three main types of squirrels that might be eyeing your home as their new winter residence: 

Grey Squirrels 

Gray Squirrels: The most common squirrel in North America, these adaptable critters are just as comfortable in city parks as they are in your attic. You’ve likely seen them in your yard, showcasing their impressive acrobatics as they raid bird feeders. These same acrobatic skills, unfortunately, make them adept at finding their way into your home. They thrive in both urban and rural environments. They actively seek warmth and shelter in the winter, making soffits, chimneys, and attics prime targets. 

Red Squirrels 

Red Squirrels: Smaller than their gray cousins, red squirrels are a rusty red-orange color and typically prefer rural and suburban areas. While less common in urban settings, they won’t hesitate to take up residence in attics and wall voids. Their breeding habits are similar to gray squirrels, meaning they can multiply quickly. They measure around 11-14 inches and weigh up to a pound. 

Flying Squirrels 

Flying Squirrels: These nocturnal rodents are rarely seen but often heard. Reaching up to 15 inches long, they have large eyes for night vision and a light brown coat with a distinctive white underbelly. Don’t let the name fool you – they glide rather than fly, using a special membrane between their front and back feet to travel impressive distances (up to 80 feet!). They often make their homes in attics and between floors, where they use insulation as nesting material. Flying squirrels are active at night. If you hear activity after dark it may be flying squirrels. 

Though they do not hibernate during winter, they spend much of the cold months” huddling” with other flying squirrels to keep warm. If you find one flying squirrel in your home in Winter, there are likely many more. 

The Hidden Dangers of a Squirrel Invasion

Squirrels might seem harmless, but an infestation can lead to significant problems: 

  • Property Damage: Like all rodents, squirrels need to chew constantly to keep their teeth trimmed. This can lead to chewed wires (a fire hazard!), damaged insulation, and holes in your walls, roof, and soffits. They will also chew to widen existing holes, making it easier for other pests to enter. 
  • Health Risks: Squirrel droppings can carry diseases like leptospirosis, salmonellosis, and even hantavirus, posing a risk to your family’s health. 

Signs of a Squirrel Infestation 

Squirrels are sneaky, but they leave behind clues. Here’s what to watch for: 

  • Droppings: Squirrel droppings are typically about half an inch long, cylindrical, and dark brown when fresh. Red and gray squirrels scatter their droppings, while flying squirrels tend to create a designated “latrine” area. 
  • Noises: Gray and red squirrels are active during the day. Listen for scratching, scurrying, chirping, or barking sounds, especially in the attic or walls. Flying squirrels are nocturnal, so listen for activity at night. Their vocalizations are usually too high-pitched for humans to hear, but their movements can be surprisingly loud. 
  • Entry Points: Inspect your home’s exterior for holes, especially around the roofline, soffits, and foundation. Any hole larger than two inches is a potential entry point. Look for gnaw marks around these holes, indicating where squirrels have widened them. 

How to Squirrel-Proof Your Home: Prevention and Solutions 

Taking proactive steps can save you from the headache of a squirrel infestation: 

  • Seal Entry Points: Carefully inspect your home’s exterior and seal any holes larger than two inches with caulk, steel wool, or metal flashing. Pay close attention to areas around the roof, foundation, and where pipes or wires enter the house. 
  • Trim Tree Branches: Trim branches at least 6-8 feet away from your roofline to eliminate easy access points. 
  • Remove Food Sources: Securely store birdseed and other potential food sources. Clean up fallen seed regularly. Consider using squirrel-proof bird feeders. 
  • Make Your Home Uninviting: Motion-activated lights, loud noises, or even strategically placed ultrasonic devices can deter squirrels. 
  • Install a Chimney Cap: A properly fitted chimney cap will prevent squirrels from entering through this common access point.
