Why Most Gap Sealing Fails
Foam on its own gets chewed through
It seals the gap and looks finished, but it is a soft barrier. Nothing about cured foam stops a determined rodent from working back through it.
Steel wool on its own doesn't hold
Wool packed into a gap mats down and compresses over time, especially in wider openings. The gap quietly reopens and nobody notices until something gets in again.
So the same hole gets sealed twice
Most kits in this category hand you one material or the other. FullStop Pest Block ships both, as the method, not as an add-on.
Where Rodents Actually Get In
The 3-Step BEEST Method
The wool is the barrier, the foam is the seal. The order is what makes both of them work.
Seal
Pack steel wool into the gap, then spray foam over it. Don't overpack, the foam needs room to expand.
Trim
Wait an hour, then cut it back flush with the scissors in the kit. Cutting earlier tears the surface.
Paint
Only if the seal gets direct sun. Wait for full cure at twenty-four hours, then use an oil-based topcoat.
Before You Start
Prep the surface
Clean and dry the area so the foam bonds properly. Size up the gap and cut enough wool before you open the can.
Mind the temperature
Shake the can and keep it between 68–77°F. Ambient needs to be 41–86°F.
Protect what's around it
Cured foam only comes off mechanically. Mask surrounding surfaces and wear the gloves.
Don't rush the trim
Wait for the one-hour mark. Cutting earlier tears the surface. Don't force a clogged nozzle either.
Walk the whole area
There is rarely just one entry point. Check pipes, vents, cable runs, baseboards, garages, attics, basements and under sinks.
Two Materials, One Method
Cures Rigid & Trimmable
Fills Multi-Surface Gaps
What's In The Box
Pest Block expanding foam
12 oz cans with their own applicator nozzle. No caulk gun needed.
Not Your Average Steel Wool
Heavy-duty interlocking fibers create a tougher, more secure fill for gaps and openings.
Micro-serrated shears
Sharp enough to cut steel wool cleanly. The scissors bundled into kits in this category usually aren't, which is a complaint worth not earning.
Wooden push tool
For packing wool into gaps too tight or too deep for fingers.
Work gloves
Steel wool splinters and cured foam doesn't wash off. Wear them.
Professional-Grade Pest Block Kits
Everything you need to seal rodent entry points properly, without a service call or a second attempt at the same gap.
Which size do I need?
Match it to entry points, not square footage. 3 Cans + 6 Rolls for a handful of gaps. 4 Cans + 6 Rolls for a typical whole-floor pass. 6 Cans + 9 Rolls for a full-house sweep.
Can I use the foam or the wool on its own?
No. Use them together, wool first and foam over the top. Each material is doing a job the other one cannot.
Can I paint over it?
Yes, once fully cured at 24 hours. Recommended for anything sun-exposed: use an oil-based topcoat.
Is it waterproof or UV resistant?
No. It hasn't been tested for waterproofing, and it isn't UV stable. Paint sun-exposed seals with an oil-based topcoat.
Is it flammable?
The foam is rated B3. Keep it away from open flame and heat sources during application and until fully cured.
How do I clean up?
While wet, wipe with acetone or a similar solvent. Once cured, remove it mechanically. See the SDS for the official procedure.
What if the nozzle clogs?
Check that it's shaken and in the right temperature range first. If it arrives clogged or defective, that's a quality issue: contact support for a replacement or refund.
