Does Spray Foam Insulation Deter Pests?

Whether you’re a contractor or a homeowner, you likely want to know that your home improvement project is going to last, and do its job well. One common factor that can wreak havoc on any home project is pests, which can sometimes destroy a home. Insects like termites can bring in contaminates while weakening wooden structures, and rodent invaders can ruin a home’s electrical system by chewing through wires.

One common project that can be rendered useless by wild invaders is home insulation. When rodents, in particular, burrow into walls and chew through materials, the warmth-retaining and moisture-blocking properties of insulation can become ineffective.

However, spray foam insulation may be a better alternative to traditional insulation batting when it comes to deterring pests. Read on to learn how.

Spray Foam Creates an Air Seal

One major pest-preventing benefit of spray foam insulation is that, unlike other forms of insulation, it seals all cracks and gaps between other structural components. Spray foam is favored for its air sealing qualities; up to 40% of a building’s energy loss is caused by poor air filtration, but spray foam can seal unwanted air gaps to create a more intentional and efficient filtration system.

Spray foam closes gaps so small and so tightly that it blocks a significant amount of air from entering or exiting a house other than through windows and doors. If unwanted air can’t find a place to slip into a home, mice and insects will certainly face difficulty. Using spray foam insulation equipment to seal a house will deter pests by giving them fewer points of entry.

Spray Foam Chemicals Aren’t A Food Source

Spray foam chemicals, unlike other forms of insulation, do not resemble food to pests in any way. Mice won’t attempt to chew or eat the chemical-based foam. Many kinds of spray foam are treated with boric acid, which is a known pest deterrent that even insects dislike. Without a source of food, many pests won’t be interested in living in your walls to begin with.

Spray Foam Can Reach Small Corners

Finally, another benefit of spray insulation is that it can reach places other types of insulation simply can’t. There are some small areas in every home where humans cannot access, like crawl spaces and other nooks. Typically, these areas would be traditionally insulated to the best of an installer’s ability, but limited physical access means a not-so-tight insulation job. Spray foam, however, overcomes this problem. Spray foam guns can reach tiny areas, preventing the nooks and crannies in your attic from becoming poorly-insulated pest havens.

Pest like rodents and insects are more than a nuisance. If left unchecked, they can cause extensive and expensive damage. Luckily, spray foam chemicals can help. Use spray foam to lock in warmth while locking pests out.
