Critter-Proof Your House Before Winter Sets In

As nights and early mornings finally settle into a below-freezing pattern, you might find yourself sharing your home with an unwanted critter or two. The first sign of an animal intrusion is likely the noise. Late at night when all should be quiet, you might be woken up to squeaking, rustling, or even hissing somewhere above your head. As winter sets in, mice, raccoons, possums, and other small animals start looking for warmer shelter, and attics are a popular place for them to reside. What’s important is to take action quickly, before they start to get too settled and begin to nest where they shouldn’t. 

Generally, the noise that the animal makes will tell you what you’re dealing with. Squeaking or chewing sounds are likely rats, scurrying is probably a squirrel or mouse, and snarls or hissing is usually a raccoon. While some of these animals are looking for a place to call home, others may have ended up in your attic by accident and are looking for a way out. It’s a good idea to know the difference. 

Almost all animals are likely to chew through wiring and bigger ones like raccoons or possums can tear apart insulation and ruin ductwork. Even small mice can make unwanted nests and leave an awful smell from their excrement. Although dealing with animal removal is a pretty awful job, leaving an unwanted visitor alone will end up costing you a lot more than sleep. If removing pests isn’t on your resume, call in an exterminator to take care of the problem. 

If you have mice or rats, they have likely moved in because there is a water source. Simple bait traps will help get the ones that are already there, but a mouse can fit through a hole the size of a dime, so rodent proofing is essential. You’ll also want to inspect for any roof leaks as part of the job.

Squirrels are one of the animals I mentioned that might have come in accidentally. They usually prefer it outside and will be looking for a way to leave your home. Soffits and vents are likely places for squirrels to be able to get in so your best bet is to install an exclusion door that lets the rodents out so they can’t get back in. 

A one-way door will also work for raccoons, who don’t mind sticking around if they find a warm, dark, and comfy place to live. However, since raccoons are nocturnal, you can make your attic less accommodating by leaving the lights on and even playing music. They’ll soon look for somewhere else to live. 

Bats are elusive in that they are very quiet and you might not even hear them unless there is a decent size colony making their home in yours. Removal is key and should only be done by a registered DEEP specialist as bats can be diseased. 

Finally, there are possums which, similar to raccoons, won’t want to leave. These guys are pretty resilient and they go to the bathroom everywhere, leaving a huge, smelly mess behind. The best method to get rid of a possum is to have it trapped and removed by a professional.

Solar Panels Make Great Homes for Unwanted Guests

I recently had a call from a reader for a roof repair. With all the rain we’ve had recently, it has been a very busy summer for remodeling professionals but this call was a bit different than your average leak. The reader had solar panels installed a few years ago and not long after, she had noticed debris peeking from underneath. Fast forward to this summer’s deluge of rain and the leaks began. 

When I got to the house, I knew immediately what had happened. Solar panels not only attract heat but also create shelter, offering two incentives for critters to build nests. Birds are one thing but small animals such as squirrels will actually chew right through the solar panel wiring as well as the roof’s shingles. In this reader’s case, the squirrels had indeed made a meal of the roof itself, causing water to get right through the plywood and into the attic. The repair entailed removing the solar panels and patching the roof to ensure it wouldn’t be susceptible to more leaks come winter. 

If you’re wondering how common this problem is, the answer is very. A solar panel makes the perfect home for an unwanted guest. It offers shelter, warmth, and easy access to food and nest-building materials. Once an animal has built a nest, it’s almost guaranteed that they are going to cause some damage unless their home is removed. 

So what’s to stop the critters from coming back? If you’ve invested in solar panels, it’s worth also protecting them from potential damage. Most solar panel companies offer a guard that works just the same as a garden fence - it protects the solar panel and underlying roof from nesting birds and animals. Nests themselves reduce the airflow underneath a solar panel, causing the area to heat up and lessen the efficiency of the system. Animals like squirrels love to chew and wiring is just plain fun to chomp right through, so you need to stop them in their tracks. 

If you’re just considering solar, don’t forget to ask your provider for an animal control solution. For those of you who have panels that aren’t protected, there are plenty of options available. To prevent unwanted guests, it’s simple to use wire mesh, but the key is to make sure there are no gaps as rodents can push themselves through tiny, seemingly impossible spaces. As with any roof work, don’t try to install a DIY solution yourself unless you are very comfortable on a ladder and have the proper safety equipment. A roofing contractor or your solar panel installer will be able to help you do the job safely.
