What is Pestblock Foam?
Pestblock foam is a type of polyurethane sealant that offers an effective barrier against pest infestation in buildings. It is designed to block tiny spaces, cracks, or gaps in a building structure. Pestblock foam effectively blocks access points for different pests such as bugs, mites, rodents, and insects.Â
Pestblock foam is an efficient DIY pest control mechanism for deterring pests in your space. They contain ingredients and pesticides that are unappealing to pests of all kinds. Pestblock foam expands to fill large and tiny holes in a building, preventing rats, ants, mice, cockroaches, wasps, mosquitoes, etc.
Pestblock Foam vs Regular Foam
Pestblock foam and regular spray foam serve different purposes. Unlike regular spray foam insulation, pestblock foam is specifically formulated with bitter-tasting ingredients to deter rodents and pests. This unique formulation makes it more effective at preventing pest infestations compared to standard expanding foams, which lack pest-repellent properties.
While both foams expand to seal gaps and cracks, Pestblock foam provides an added layer of protection as a pesticide barrier.
How Does Pestblock Foam Effectively Protect Against Pests?
Pestblock foam works by creating a barrier against pest infestation in buildings. It is a preventive pest control that offers physical and chemical barriers in walls, holes, foundations, and crawl spaces. When Pestblock foam, a rodent-resistant insulation, is applied, it expands and hardens to seal entry points, creating a dense barrier that effectively deters rodents.
PestBlock foam offers effective pest control in the following ways;Â
- Seals entry points for pests in a building.Â
- They are unchewable, making them unappealing to pests.
- Water-resistant.

Will Pestblock Foam Keep Mice Out?
Pestblock foam deters mice by sealing holes and spaces around a building. Expanding foam sealant for mice effectively creates an airtight blockade, making it impossible for mice to wriggle a way through. Furthermore, the dense nature of Pestblock foam offers a strong barrier against any persistent attempt to gnaw through. For added effectiveness, pestblock foam can be paired with materials like steel wool or metal mesh to further prevent pests from nesting around sealed areas.
Can Pests Enter Through Pestblock Foam?Â
Pestblock foam becomes hard and dense after curing, making it less likely for pests to pass through. It creates an impenetrable barrier that prevents pests from gaining access.Â
Why Choose Pestblock Foam for DIY Pest Control?
Pestblock foam is the ideal solution for do-it-yourself pest control measures for several reasons. Choosing pestblock foam offers a convenient and cheap way to prevent pest infestation.Â
Here are 5 reasons why Pestblock foam is the best DIY pest control measure;
- Easy To Use: Pestblock foam comes in easy-to-use spray cans and applicator, allowing you to quickly seal tiny crevices in your space without hiring a professional.Â
- Affordable: According to ForbesHomes, the average cost of extermination is $250 for one visit, but it can reach up to $8,000 in extreme cases.. Preventing pest infestation with pestblock foam is cheaper than paying for extermination costs.
- Saves Money: Pestblock foam saves money by improving energy efficiency in a building. This helps to improve indoor air quality and reduce energy consumption by 30%.
- Water Resistant: Pestblock foam offers a water-resistant barrier. This helps to improve durability and prevent mold growth. In addition, the water-resistant properties of Pestblock foam eliminate breeding grounds for insects like mosquitoes.
- Mess-free: Pestblock foam is not messy at all! It eliminates the possibility of handling or deposing dead insects or rodents. This reduces the risk of exposure to germs or viruses.
Why Use Pestblock Foam Instead of Traditional Traps for Mice?
Pestblock foam is a preventive approach, while traditional traps are curative. Unlike traps that catch individual pests, Pestblock foam seals entry points, preventing infestations altogether. This foam for mice creates a durable, airtight barrier that blocks rodents from entering your home.
Additionally, Pestblock foam eliminates the need for handling or disposing of dead pests, making it a more hygienic and convenient option.
Using pestblock foam as a mouse-proof insulation or a mouse shield foam ensures a long-term solution to rodent problems, whereas traditional traps offer only short-term results.

Is Pestblock Foam Safe for Pets and Children?
Pestblock foam becomes safe for pets and children once it fully cures, typically within 8 to 24 hours depending on the product. During application and curing, ensure proper ventilation to avoid exposure to volatile organic compounds (VOCs), which may be harmful if inhaled.
Where to Use Pestblock Foam?
Pest-blocking foam offers a secure and convenient way to protect your space against pest infestation. Pestblock foam provides the best pest prevention results in places with small or large holes.
Here are common places where you can use pestblock;
- Attics
- Crawl spaces
- Garages and basements
- Kitchen and pantry areas
- Plumbing penetrations
- Doors and windows
- HVAC ductworkÂ
- Food-Sourced operations like restaurants, cafes, food storage warehouses, etc.
- Food processing plants - grocery stores, farms, etc.

Where Not to Use Pestblock Foam?
Pestblock foam must be avoided in the following places;
- Close to Heat Sources: Uncured foam is flammable; applying pestblock foam around heat sources can ignite a fire. Common heat sources to avoid are stoves, fireplaces, furnaces, ovens, and hot pipes.
- Around Electrical Wiring: Do not apply pestblock foam directly on electrical wiring or fixtures.Â
-
Exposed Areas: Pestblock foam should not be applied to areas where children or pets will be exposed to it. Chewing pestblock foam causes health hazards for pets and infants.
How Do Pestblock and Spray Foam Complement Each Other?
Pestblock foam and spray foam complement each other by creating a comprehensive barrier that combines pest control and insulation. Pest Foam sealant is applied to tiny spaces where pests enter a building. On the other hand, spray foam seals walls, attics, and the entire building.Â
Together, they work in two key ways:
- Pest Control: Spray foam and Pestblock foam are both excellent pest-deterrent products. Pestblock foam and closed-cell spray foam are highly dense and impenetrable for pests. They are also unchewable for insects and rodents.
- Energy Saving: Pestblock foam is used in gap filling, while spray foam offers air sealing. The sealing abilities of pest spray foam help in reducing air infiltration in buildings. This helps to improve energy efficiency and indoor air quality.Â
What Are the Best DIY Solutions to Prevent Pests?
Pestblock foam is one of the many do-it-yourself pest solutions that can help prevent pests from entering your home.
Here are other popular DIY pest solutions to tackle pests;Â
