Winter’s Unwanted Houseguests: Animals in Your Home

As colder weather finally settles in, you might find yourself sharing your home with some unexpected guests. Mice, raccoons, squirrels, and even possums often look for warmer places to stay as the weather grows colder. Attics make an ideal retreat, providing shelter from the elements. If you’re hearing strange noises—such as squeaks, scurrying, or even hissing—especially late at night, it’s likely that a critter has moved in.

If an animal has taken up residence, it’s important to act quickly before they get too comfortable. Once settled, they may start nesting, which can lead to further damage. Most animals leave clues that help identify them. High-pitched squeaks or chewing sounds usually mean rats or mice, while fast scurrying is often a sign of a squirrel or a mouse. Raccoons, known for their snarling and hissing, tend to make more aggressive noises. While some animals move into your attic on purpose, others may be there by accident and are simply trying to find a way back outside. Understanding what you’re dealing with can help you determine the best course of action.

Animals in your attic aren’t just a nuisance; they pose serious risks to your home. Most will gnaw on anything they encounter, especially mice and rats, which chew through wiring, creating fire hazards. Larger animals like raccoons and possums can tear apart insulation and ruin ductwork, leading to costly repairs. Their droppings and urine can also create unpleasant odors and unsanitary conditions.

If your problem is mice or rats, they likely came in looking for warmth and water. These small animals can squeeze through holes as tiny as a dime, so sealing any potential entry points and fixing leaks is essential. Setting bait traps can catch some of the rodents already inside, but long-term solutions require securing all access points to prevent re-entry.

Squirrels, on the other hand, usually prefer the outdoors and may have come into the attic by mistake. They often get in through soffits or vents. One of the best ways to help them leave is by installing an exclusion door—a one-way exit that allows them to leave but not return.

Raccoons are more determined and will stay put if they find a warm, dark spot. Since they’re nocturnal, try leaving lights on in the attic and playing music to encourage them to find somewhere quieter to rest.

Bats are trickier, as they’re usually very quiet unless there’s a large colony present. Due to potential health risks, bat removal should only be performed by a certified DEEP specialist.

Finally, possums, much like raccoons, are resilient squatters that often refuse to leave. Their droppings can quickly accumulate, leaving a huge mess and a foul odor. The best way to handle a possum is to call a professional for humane trapping and removal.

Ultimately, dealing with unwanted animal visitors is best left to professionals. Ignoring the problem can result in more than a few sleepless nights—it can lead to extensive and costly repairs.

What to Know About Ice Dams

This winter has been fairly mild but the season is still in full swing and it won’t be long until we get another storm to remind us that we live in New England. Before that happens, I always like to talk about the dangers of ice dams and the reason why so many homes in our area get damaged by them. 

An ice dam is a solid mass that forms when heavy snow blankets the roof, creating an extra layer of unwanted insulation. As warm air rises from your house and up through your attic, it causes the snow to melt and the water to slide down into the gutters. This would typically be just fine, but because so many homes in our area aren’t properly insulated, the melting ice will often make contact with the cold eaves of the roof and freeze again instead of draining off through the gutters. This forms a large ice mass at the gutter line, which will grow if not taken care of.

Solid ice is heavy and can easily pull gutters loose. The dam can even get strong enough to lift up your roof shingles, creating gaps that let the water through and into the attic. This is when people start to see leaks in their ceilings and walls. 

The only way to prevent ice dams from forming is to have your home properly insulated and ventilated. More than 75% of homes in our area are under-insulated which causes the heat from your home to shoot right through the roof. Because insulation and ventilation weren’t regulated when most of the homes were built in this area, a lot of us have houses that are better suited for Florida winters than our cold Connecticut climate. 

Having appropriate insulation and ventilation will not only keep your home free from ice dams but will also keep you much more comfortable in both the winter and the summer. You’ll feel the difference immediately, and you’ll see the benefit in your energy bills too. A house that can breathe and can properly regulate its own temperature will also be less like to accumulate mold and mildew which is not only damaging to your house but also to your health. It’s a simple solution to keep your family, your home, and your wallet healthy.

Safeguard Your Pipes in Freezing Weather

As chilly temperatures settle in for the week, it's crucial to ensure the well-being of your pipes. Dealing with a burst water pipe during winter is not only a common inconvenience but also an expensive hassle. Here's a guide to help you minimize the risk of such issues.

Protect Outdoor Water Sources

If you have outdoor water sources like a pool or sprinklers, take preventive measures. Drain them to avoid standing water freezing and expanding when temperatures drop. Anything in an unheated area is vulnerable.

Secure Outdoor Hoses

Remove and drain all outdoor hoses, storing them away for the season. Close the valves to prevent seepage and ensure they are in good condition for future use.

Insulate Your Attic

Install an insulated box above your attic hatchway to retain heat in your house. An underinsulated attic is a potential risk, being the coldest part of the house.

Insulate Water Supply Lines

Identify water supply lines in your home and insulate both hot and cold water pipes. Inexpensive options like pipe sleeves and heat tape can enhance heat retention and prevent freezing.

Seal Unheated Areas

Keep unheated areas such as garages closed to prevent freezing. Garages often have water lines that can easily freeze when temperatures plummet.

Adjust Thermostat When Away

If you plan to be away and want to save energy costs, don't set the thermostat lower than 55 degrees. This prevents freezing issues while keeping energy usage efficient.

If a pipe is already frozen, consider these steps:

• Leave faucets slightly open to encourage water flow and melt partially frozen pipes.

• Use a hair dryer, space heater, or heating pad to circulate water in the frozen section.

• Check all water sources if one pipe is frozen, as others could be affected.

• If unsure, call a plumber to prevent serious and expensive damage.

• Shut off the main water valve while keeping faucets open.

A burst pipe can lead to serious flooding and long-term problems like mold and mildew, affecting your family's health. Don't wait to protect your home—act now, especially during the colder winter months.
