Pest-Proofing the Attic Before Cooler Weather Comes

There are certain signs of fall we all look forward to: cooler nights, the first leaves changing, apple cider, and football on the weekends. And then there are the signs you’d rather not encounter, like scratching, scurrying or thumping coming from somewhere above your ceiling.

Once the weather starts getting colder, we’re not the only ones thinking about staying warm. Mice, squirrels, bats and other critters start looking for protected places to spend the colder months, and a warm, dry attic can be pretty appealing.

I’m certainly not an exterminator, but as a roofer, I spend a fair amount of time in attics. Over the years, I’ve seen firsthand the mess animals can make once they get inside. They can tear up and nest in insulation, chew on wood and wiring, leave behind droppings, and create some pretty unpleasant odors. Squirrels and other animals can also damage vents, soffits and other parts of the roof while getting in and out. A small entry point can eventually turn into a much bigger home repair. That’s why this is a good time of year to do a little prevention.

Start outside, but don’t expect to find every tiny opening an animal could squeeze through. From the ground, you’re really looking for the more obvious trouble spots: damaged or missing soffit, loose fascia, broken vent covers, damaged siding or anything along the roofline that looks like it has shifted or deteriorated.

Tree branches are worth a look, too. If they’re hanging directly over or touching your roof, they can give squirrels and other animals a pretty convenient route onto the house.

Then, if you can safely access your attic, take a look around inside. One of the easiest things to spot is daylight coming through somewhere it shouldn’t. You can also look for disturbed insulation, droppings, nesting materials, or evidence that something has been chewing. Pay attention to the areas around vents, pipes, wiring and other places where something passes through the roof or an exterior wall.

Your garage and basement deserve a look as well. Check weatherstripping around doors and look around pipes, cables and utility lines for gaps.

The important thing to remember is that animals don’t need a wide-open door. Some can get through surprisingly small spaces. So you’re probably not going to walk around your yard and identify every possible mouse-sized opening in your house. The goal is to find damaged or vulnerable areas and take care of them before something else takes advantage.

Some fixes are simple DIY projects. Replace worn weatherstripping. Secure a loose vent cover. Keep garage doors closed when you aren’t using them. Store firewood away from the house, clean up spilled birdseed, and avoid leaving pet food outside overnight.

Other repairs, particularly anything involving the roof, high soffits or fascia,  are better left to someone who can safely reach them and knows what they’re looking at.

If you already suspect you have an animal living in the attic, that’s when I’d call a wildlife or pest professional rather than simply plugging the hole. You don’t want to trap an animal inside, and you definitely don’t want to seal young animals inside while their mother is outside.

Remember, once we get our first stretch of genuinely cold weather, animal professionals get a whole lot busier. If you’ve been hearing noises or seeing signs that something has moved in, or you’ve had problems in the past, don’t wait until November to deal with it.

Fall home maintenance is mostly about staying one step ahead of winter. Clean the gutters. Check the roof. Put away the hoses. And while you’re at it, make sure you’re not unknowingly offering free winter accommodations to the neighborhood wildlife.

A Spring Roof and Gutter Check

Spring is the ideal time to check in on your roof and gutters. With better weather and clear visibility, it’s easier to catch small issues early, before they turn into expensive repairs.

1. Start with Safety

Before anything else, set yourself up safely. Use a sturdy ladder on level ground, wear shoes with good grip, and avoid working alone. If your roof is steep or hard to access, this is your cue to call in a professional.

2. Do a Walkaround First

Stay on the ground and take a slow lap around your home. Look for missing shingles, uneven rooflines, or piles of debris left behind from winter storms. Binoculars can help you get a closer look without climbing up.

3. Take a Closer Look at the Roof

If conditions are safe, get up there for a better inspection. Freeze-thaw cycles can loosen shingles and weaken vulnerable areas. Pay extra attention to spots like roof valleys, chimneys, and skylights.

4. Check Flashing and Seals

Flashing around vents, chimneys, and joints can crack or shift during the winter. Look for rust, gaps, or worn sealant. These small issues are often where leaks begin.

5. Clear the Gutters

Gutters tend to collect everything winter throws at them like leaves, twigs, and shingle grit. Clean them out thoroughly and make sure downspouts are draining properly. If water can’t move away from your home, it will find somewhere else to go, like your foundation.

6. Make Sure Gutters Are Sloped Correctly

Water should flow easily toward your downspouts. If you notice standing water or overflow, check the pitch and adjust the hangers if needed. A slight slope makes a big difference.

7. Inspect Fascia and Soffits

These areas often show early signs of trouble. Look for peeling paint, soft spots, or signs of pests. Moisture damage here can quietly spread if left unchecked.

8. Check the Attic

Head inside and look up. Water stains, mold, or a musty smell are red flags. While you’re there, make sure vents are clear so your attic can breathe. Trapped moisture is never your friend.

9. Document What You See

Take photos of anything that looks off. It makes it easier to track changes, explain issues to a contractor, or support an insurance claim if needed.

10. Bring in a Pro

A yearly professional inspection is worth it. Contractors know where problems like to hide and can catch issues early, before they turn into major repairs.

Spring is all about resetting and your home deserves the same treatment. Your roof put in a long shift this winter. Give it a once-over now so it’s ready for everything the next season brings. A little attention today beats a big repair bill tomorrow.

Unwanted Holiday Houseguests

As winter 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.
