Why Standard Materials Don't Hold Up
The most common reason homeowners call us for a repeat wildlife problem is that someone — often a previous contractor or the homeowner themselves — sealed an entry point with materials that aren't rated for animal resistance. Expanding foam, standard caulk, lightweight aluminum screening, and thin plastic vent covers can all be breached by squirrels, raccoons, rats, and mice with minimal effort.
Animals that have used an entry point before know exactly where it is and will work persistently to reopen it. The material sealing that gap needs to be tough enough to withstand gnawing, scratching, and pushing from animals that are highly motivated to get back in.
Where We Use Pest-Blok
Pest-Blok is versatile and can be applied in areas where materials like metal flashing or hardware cloth aren't practical. Common applications include:
- Under metal roofing ridge caps
- Foundation vent guards
- Irregular gaps in foundations and masonry
- Spaces around vents and exhaust fans
- Cracks and openings in siding where traditional repair materials won't breathe properly or allow drainage
- Entry points where a durable, animal-resistant seal is needed
Part of a Complete Exclusion Solution
Pest-Blok isn't a standalone product you apply and hope for the best. It's part of a professional exclusion strategy that starts with a thorough inspection, identifies every entry point and vulnerability on your home, and addresses each one with the appropriate material and method. The right material in the wrong location won't hold. The right material in the right location, installed by someone who understands how animals access structures, will.
Pest-Blok is just one tool in our exclusion toolkit. For some openings, we may use heavy-gauge screening, commercial-grade coated sheet metal, hardware cloth, and structural repairs as part of our comprehensive animal proofing and exclusion services. Our exclusion and repair services combine Pest-Blok products with structural repair, reinforced metal, and professional installation to create a complete barrier that holds up over time.
How We Apply Pest-Blok
Full Inspection
We walk your entire property exterior to identify every current and potential entry point — including the ones that aren't obvious from the ground. Knowing where animals access the structure is the foundation of any effective exclusion plan.
Material Selection
Not every gap calls for the same solution. We determine which material is most appropriate for each opening — Pest-Blok, hardware cloth, metal flashing, or structural repair — based on the location, size, and species pressure involved.
Professional Installation
Pest-Blok is installed to manufacturer specifications and backed by our workmanship. Proper installation is what makes the difference between a seal that holds and one that fails within a season.
Documentation
We provide a record of every entry point sealed and the material used, along with any recommendations for areas that may need attention down the road.
