Can the Right Insulation Stop a Rat Problem?

Can the Right Insulation Stop a Rat Problem?

Rat in Attic

There are several insulation brands that claim to be rodent-resistant. Both foam insulations and cellulose insulation both say that they are rat-proof, but sadly it isn't so. There is no such thing as an insulation which actively repels or prevents rats.

Even insulation that contains boric acid just can't get the job done. The poison in these insulations just isn't potent enough to actually kill rats...and poisoning a rat population comes with its own problems. Ask anyone who has ever had a dead animal of any kind trapped behind their walls. The smell eventually turns a home unlivable!

The fact is that your attic is an ideal place for rats. It's warm. It's dry. Insulation makes ideal nesting materials. 

Decent Insulation Choices

Obviously you've got to insulate your attic with something, and there's absolutely nothing wrong with choosing an insulation that doesn't make rats quite as happy as the pink stuff. They love the pink stuff (fiberglass insulation). 

Instead, consider loose-fill cellulose insulation. Thick, dense, clumpy, and dry, it packs small areas tight. Cellulose is made of wood. Rats can certainly chew it, but it's not that useful for them to chew. It does not make for a sturdy, warm nest which means rats tend to ignore it.

If you want an insulation that rats don't particularly like the smell of, hemp insulation works. While it takes a license for Texas growers to plant and harvest industrial hemp, it is legal to build with in our state. Hemp insulation is eco-friendly, effective, and moisture-resistant. The taste is a little bit bitter for them, they don't like the smell, and it's often just more trouble for them than its worth.

We certainly wouldn't dissuade you from choosing an insulation that is less attractive to rats and less likely to be damaged by them. We just want to reiterate that there's no insulation choice you can make that will keep rats out of your attic. For that, other steps need to be taken.

What's Truly Effective at Deterring Rats and Mice?

The first step that's effective is seeing to sanitation around your home. Feed your pets at a specific time and take up their food when they're done. Make sure trash cans around your property are properly sealed off and secured. If you feed birds, use a feeder basket and reduce the amount of food you're using. You're aiming to get just enough food to feed the birds during the day. If any food is left over at night, you're overfilling those feeders.

Clean up "hidden" areas where food tends to congregate too, such as beneath refrigerators or behind stoves.

Keeping your lawn mowed, trimmed, and raked can really help too, since this provides rats with fewer places to hide. 

If you already have rodents in your house we need to find and block off all their entry points, then trap them to get the ones that are in your house out of your house for good. If you've been lucky enough to avoid them thus far, getting a pest control specialist to seal up entry points now can keep you lucky in the future.
