Will Rats Nest In Your Attic Fiberglass Insulation?
Rats love to burrow into warm and cozy places. So what place could be better for them than the nice and squashy insulation in your attic?
Once you discover a rat infestation in the attic, you’re in trouble as rats are known to cause some of the worst attic insulation damage when they burrow into the insulation. The insulation is easy to gnaw on, break into pieces, and move from one place to another for nests.
Besides building their nests, rats also occasionally eat the insulation and leave gaps behind. And that’s bad news when it comes to your home heating and cooling bills.
When they’re hanging out in your attic, it can also lead to serious safety and health hazards. These pests are going to leave their waste products behind, which in turn can affect the air quality in your home.
Where Do Rats Make Their Nests In Attic?
The location needs to be sheltered, dry, comfortable, quiet, and safe for raising their young, that’s why the attic is a perfect place for them, particularly for roof rats. The attic offers them plenty of such spots and corners to hide and lots of crawl spaces in which they can roam around.
There’s an abundance of materials these animals can use to build their nests. They will shred just about any available material with their sharp incisor teeth.
They will happily nest in the insulation but also in any scavenged pieces of cardboard boxes, newspapers, plastic items, cloths, or clothing found in the attic.
They might crawl between the insulation and the floorboards. This includes loose-fitting solutions like wires, nails, or packing straps. If the rat can get in there, it will snuggle and breed between the layers as it makes an appealing and cozy shelter where they can build a nest for their offspring.
A body of a rat is highly flexible, thus, these pests will squeeze through any small opening or hole without any problem. If the hole isn’t big enough at first, they’ll start chewing on its edges to make the hole big enough for them to eventually squeeze through.
Will Rats Nest In Attic Fiberglass Insulation?
Many types of insulation are very vulnerable to rats and provide them the perfect nesting ground as well as a great food source. Unfortunately, there is no such insulation that guarantees 100% protection against rats and other rodents. If these pests gain access to your attic insulation and choose to use it as it suits them, they will destroy it, no matter the material the insulation is made of.
Fiberglass is one of the most popular types of insulation. It is a lightweight, rot-resistant, durable, and strong material that offers high thermal insulation. It also has the ability to easily get molded into various shapes which makes it very convenient for rats to make nests, and fiberglass can be moved and reshaped as needed.
Fiberglass insulation is probably the best nesting material out there for rats, they just love the stuff to burrow and nest in. It’s easy to tunnel through low- or mid-density fiberglass. These scurrying critters either directly nest in fiberglass batts and panels, or they harvest the material and move it to a nearby location to build their nests.
Many homeowners prefer fiberglass batts for their attic insulation. Even though fiberglass batts are so popular, they are definitely not ideal if you want to keep rats away. Fiberglass batts come in thick, spongy, rolled-up sheets that are very inviting to rodents looking for a cozy place to nest and call home.
On the other hand, loose-fill fiberglass might be a better choice than fiberglass batts from a rodent perspective. This type of insulation is blown using a special machine and since it’s a loose material, it tends to fall in on itself. Thus, loose-fill fiberglass insulation is less appealing to rats and other rodents than other types of insulation.
Homeowners should take steps to keep rats away and ensure their attic insulation remains functional and intact for as long as possible.
So if you experience damage to your insulation due to rat infestation, you need to get it repaired or replaced as soon as you can. When doing that, it’s also important to investigate if there are any persistent rodents left that could cause additional damage in the future.
