At Armored Insulation, we’ve seen it all homeowners battling unwelcome pests sneaking into crawlspaces, attics, and wall cavities. It’s frustrating, invasive, and can lead to costly damage. Many in Benton, KY are turning to a lesser-known yet highly effective solution: spray foam insulation. But does it actually help with pest control? That’s the question we hear time and again.
Here’s what we know: when installed correctly, spray foam does more than just keep your home warm in winter and cool in summer. It can play a major role in sealing out pests. In this guide, we’ll explain how it works, why it matters in our region, and what makes our approach at Armored Insulation so effective.
By the end, you’ll understand exactly how spray foam insulation can reduce pest intrusion in your Benton home and how we make it happen with precision, care, and local know-how.
Most pests don’t barge in through the front door. They squeeze through gaps, cracks, and vulnerable seams often ones you never see. Spray foam insulation fills those tiny pathways before insects and rodents ever find them.
Spray foam expands into hard-to-reach places, sealing corners, sill plates, and framing connections that fiberglass batts or cellulose leave exposed. Unlike traditional insulation, spray foam forms a continuous barrier. That matters in Benton, where high humidity and older homes increase the risk of small entry points around foundations, eaves, and utility penetrations.
We’ve insulated homes where mice entered through cracks as narrow as a pencil. After installing closed-cell spray foam along the rim joists and attic floor, the problem stopped cold.
Our region’s seasonal shifts especially humid summers and chilly winters cause building materials to expand and contract. Over time, that creates small openings where pests can get in. Benton homes, particularly older builds, often have gaps around pipes, vents, and soffits.
Spray foam insulation addresses this by forming an airtight seal that flexes with the structure. No shrinking, sagging, or gaps reopening over time. Once installed, it continues protecting year after year without degrading like other materials.
Our technicians don’t just spray and walk away. We inspect every square inch of your home’s structure, looking for places pests exploit. Our process is meticulous tight foam application in rim joists, wall cavities, behind electrical boxes, and along foundation lines. This isn’t just insulation. It’s proactive protection.
Spray foam doesn’t just block entry. It alters the environment that pests find attractive inside your walls and attic. That’s a major reason why homeowners notice a drop in activity post-installation.
Pests like rodents and insects seek out soft nesting areas loose fiberglass, cellulose, cardboard, insulation scraps. Spray foam offers no such refuge. It hardens into a solid, non-absorbent surface that doesn’t retain moisture, offer bedding, or encourage burrowing.
Rodents and bugs thrive in dark, moist spaces with loose fibers to build nests. Fiberglass insulation becomes a five-star hotel. But spray foam? It changes the script.
Once the foam is cured, it leaves behind no loose material to shred and no damp pockets to burrow into. Closed-cell foam in particular is water-resistant, making the space less hospitable to insects like ants or silverfish, which are drawn to moisture.
Our area has a high water table and frequent seasonal rains. That moisture can sneak into crawlspaces and wall voids. Where there’s dampness and organic material, pests follow.
We’ve worked on homes where roaches and ants had colonized damp fiberglass under the kitchen floor. After removing it and installing closed-cell spray foam, the pests disappeared without needing repeat treatments.
Let’s be clear spray foam isn’t a pesticide. It doesn’t kill pests. What it does is make your home less attractive to them and far more difficult to enter. That makes it a powerful partner to professional pest control.
Many pest control companies in Benton recommend sealing up homes as part of integrated pest management. Spray foam is one of the most effective ways to do that. It closes the gaps that bait traps and sprays can’t reach.
We frequently coordinate with pest control specialists before and after insulation jobs. If you’re dealing with an infestation, it’s best to treat the issue first then let us come in and seal things up to prevent future problems.
Our team can also spot signs of current or past pest activity during your insulation consultation, helping you know what to address.
Homeowners sometimes attempt caulking gaps or stuffing steel wool around pipes. It helps, but it’s rarely enough. Spray foam creates a more complete, lasting seal across every vulnerable surface not just the obvious ones. We’ve seen DIY fixes leave attic bypasses wide open to bats and mice. Our foam solutions don’t miss a spot.
Fiberglass and cellulose have their place, but when it comes to pest control, they fall short. Spray foam simply provides a higher level of protection.
Where other materials sag, compress, or shift over time opening new paths for pests spray foam stays firmly in place. And unlike fiberglass, it doesn’t invite nesting.
If pest resistance is a top priority, closed-cell spray foam delivers the highest performance. It’s dense, moisture-resistant, and adds structural integrity to the surfaces it bonds with. That extra rigidity means pests have a harder time chewing through it, too.
Open-cell foam still seals air leaks effectively, but it’s softer and more vapor-permeable. For basements, crawlspaces, and attic rims areas prone to pest intrusion we recommend closed-cell almost every time.
We use high-quality foam, installed by seasoned professionals. That matters. A poorly applied foam job won’t bond properly, won’t expand fully, and won’t give you the pest-blocking benefits you need. We inspect every detail, making sure the insulation protects not just against heat and cold but against the pests that come with them.
You don’t need to accept pests as a fact of life. With the right insulation, you can reduce the risk and take back control of your space.

No. It blocks new pests from entering and discourages nesting, but it doesn’t eliminate current infestations. We recommend addressing active pest problems before foam installation.
It’s rare, especially with closed-cell foam. The hardened surface deters most pests, but extremely persistent rodents may still try. The key is eliminating attractants and entry points.
When installed correctly, spray foam can last 20+ years without degrading, sagging, or losing its seal.
Yes. Our team applies it carefully around electrical boxes, wires, and pipes without risk of damage or obstruction.
Absolutely. In fact, many pest control strategies are more effective when combined with proper air sealing via foam insulation.
Yes, we regularly coordinate with local pest control providers to create comprehensive protection plans for our clients.
It costs more upfront but often saves homeowners money over time by reducing energy bills and pestissues.
Yes. By sealing off entry points and eliminating moist nesting areas, spray foam makes it harder for insects to establish colonies.
Any odor during installation dissipates quickly. We use low-emission foam that’s safe and stable once cured.
We’ll assess your space and recommend the right product for your needs. Closed-cell for moisture-prone or vulnerable areas, open-cell for interior walls and less critical zones.
