Attic Insulation That Repels Rodents
When mice or rats invade the attic, insulation is usually the first thing that gets chewed up and destroyed by the vermin. Then, instead of existing as the energy-saving product that it was designed to be, it becomes a popular home and breeding ground for rodents. Unfortunately, rats and mice love insulation for a variety of reasons. It’s warm, provides excellent material for building nests, and is often an enjoyable thing to chew, sometimes even consume.
It’s usually a miserable time for homeowners when insulation gets destroyed because it’s not exactly cheap to reinstall. It’s also extremely inconvenient to replace on your own if you don’t know what you’re doing, and it’s relatively dangerous to handle without professional experience. It’s no secret that rats and mice carry harmful diseases. They leave these atrocities behind in their saliva, droppings, and urine, all of which becomes infested within the insulation, making it impossible to restore!
However, you can make it easier on yourself in the future by installing a type of insulation that won’t succumb to the teeth and claws of rodents so easily. In fact, there are certain kinds of rodent proof insulations that make it difficult for rats and mice to even enter your home in the first place. Of course, without properly rodent proofing your attic, the vermin are bound to find a way into your home, regardless, which is why rodent proofing measures should still be met.
What Kinds of Insulation Do Rats and Mice Like the Most?
This answer will vary from home to home, but common types that you typically see becoming infested are traditional fiberglass and cellulose. Of course, these are very effective types of insulation, but they ultimately fail when it comes repelling rodents because of a few main factors.
- A loose-fill fiberglass application, and any application that involves paneling, will typically leave gaps in the walls, around the floorboards, and behind the insulation, providing enough room for rodents to chew their way into your home through pipes and walls etc… Remember, they only need ¼ of an inch to gain entry!
- Cellulose insulations are made of recycled materials like newspaper that naturally attract the rodents’ nesting instincts. When insulations are installed without taking proper, rodent proofing measures first, the trapped heat can easily attract critters looking for a warm place to sleep.
Luckily, there’s a solution to keeping your sanity and your insulation lasting a little longer! Check out these two kinds of rodent proof insulations that you may want to consider.
1. Polyester Insulation
All insulations are rated by an R-value system, which is a material’s resistance to conductive heat flow. According to this system, polyester insulation rivals some of the best materials out there, like that of the popular fiberglass insulation. What makes polyester unique though, is that unlike typical fiberglass, it doesn’t produce an itch, is dust free, and has almost a no-tool installation, making it a much greener and convenient product to produce commercially and install in the home.
What makes polyester a suitable combat to rodents, is its special heat-bonded material. The fibers are fused together with heat, which not only ensures its resistance to smoking and burning, but the product is also immune to the scratching and gnawing of rodents. The tiny critters can’t so much as make a tear in the insulation, which forces them to give-up their fight and scavenge elsewhere. Even if one is persistent enough to keep trying, its claws will only catch in the product, discouraging it from continuing, lest it becomes trapped.
Although a more expensive approach to attic insulation, polyester could end up saving you time and money in the long-haul, making it one less thing to worry about in case a rat or mouse infestation were to arise.
2. Spray Foam Insulation
This is by far the most effective insulation that repels rodents. Spray foam insulation is water-blown, formulated to withstand humidity, mold, and dust, and it will not degrade over time like other traditional insulations. Mice and rats are not attracted to the product as a food source, and because of its foam-like texture, it’s also an unideal place for the rodents to burrow and build their nests. With Spray foam insulation, you never have to worry about gaps in the walls or floorboards because of the expanding nature of the product, which can expand up to 100 times its size! Since it is such an exceptional sealer, spray foam is extremely effective for rodent proofing and can be used to fill existing gaps and holes in the attic walls.
Water-blown spray foam is open-celled, which means it’s lighter and less dense than its closed-cell counterpart and will allow moisture to drain out of it flawlessly, leaving behind no residue. Some more modern spray foam insulations are made with no harmful ingredients, resulting in an appropriate choice for those looking for a greener and more effective solution to other products on the market. It’s a worthy investment that excels at keeping rodents out of your attic while preserving your warmth and comfort as any great insulation should.
How to Make Your Existing Insulation Rodent Proof
Sometimes, the most effective rodent proof insulations are simply located in a rodent-proof attic. Let’s face it. Our budgets aren’t always able to hold up to our great expectations. Buying all new spray foam or polyester insulation could become an amazing investment, but it’s not always a realistic one. Thankfully, there’s a way to keep your existing insulation lasting longer, and your attic free from rodents. Once you understand what drives rats and mice into your attic, you can take simple measures to counteract their behavior. Make your attic a place they won’t want to visit, and they’ll be out of your insulation too. Here are some basic tips to follow.
1. Seal Up All Entry Points
Rodents invade the attic through any means they can find. Piping, ventilation, roofing, you name it! Find and seal up any holes and crevices you can find, especially around pipes and insulation. Wire mesh applied with a quick-drying concrete or caulking is the best way to stop a mouse from chewing its way back into your home.
2. Maintain Trees
Roof rats commonly use tree branches to gain access into your attic. Always be sure to trim back trees and nearby foliage so they’re at least 18 inches away from your house. Rats can still jump onto your roof if they’re too close.
3. Tidy Up
Rats and mice love a messy environment. It makes it easy for them to hide and keep away from predators. Attics also provide lots of warmth and shelter for their nests, and they don’t have to go far to search for food. Having a nice clean and organized attic will greatly reduce their attraction to the space, as it minimizes their hiding places. Organize and declutter as much as possible! Lived-in attics with added windows and lights almost never see the likes of pesky trespassers.
