0 of four things confirmed
These are the four things we could check for a pest block can, and nothing else. Not a performance score: nothing on this page was applied or tested by us. How the pest block page is ordered.
- Brand data sheeta safety data sheet or a brand page is published, no technical data sheet found
- Claim checkableThis can claims no pesticide, so its claim is the barrier itself, and the figure that would make it checkable is the size of gap the wool and foam are meant to close. Neither the store nor the can states one. No data sheet or safety sheet is published for this foam; the store’s FAQ refers to "the SDS" and links none.
- Brand-channel sellerNo marketplace listing as of October 18, 2026. The kit is sold only on the BEEST store, so there is no marketplace seller to check.

Research summary, not a hands-on test. Product claims on this page are attributed to the sources and dates shown. Before use, read the exact product label, the current safety data sheet and the application instructions, and confirm ventilation, protective equipment, occupant isolation and re-entry or reoccupancy conditions. A surface-burning classification alone does not establish approval to leave foam exposed or to use it in a particular assembly.
Report a product error The claim What the documents state Documents Right of reply
The claim, in the seller's words
The can says "Pest-blocking foam barrier" and "Lock in protection. Lock out pests.", with "Blocks insects" and "Blocks mice" under its icons. The store sells it as "a two-material system for sealing rodent entry points," steel wool packed first and foam over the top, and says "Seal rodent entry points permanently." Where the line runs
Which side of the pesticide line this can's words fall on
The treated-article exemption at 40 CFR 152.25(a) covers a pesticide put into an article to protect that article, so a can with no pesticide in it sits outside that question. FIFRA asks a different one. A product can be a pesticide because of what it is represented to do, whatever is or is not inside the can, so what the reading turns on is the wording. The maker's own wording is below.
Says it has no pesticide
Lock in protection. Lock out pests. No pesticide is named or claimed anywhere, so no registration number applies: the barrier is the steel wool and the foam seals over it. "Blocks insects" on the can goes further than a seal does, the same shape of wording as Great Stuff PRO’s, and whether wording of that kind carries a regulatory consequence is a question for a regulatory specialist that this page does not decide.
This is a reading of the maker's own words and nothing else. We have not tested this can, no maker in this category names its active ingredient, and the exemption also turns on that ingredient being registered for this use, which is the part nobody publishes. So this does not say a can is unlawful and we are in no position to say so. Every pest can in our set, side by side.

Our reading
New on the BEEST store in late September 2026, and sold as a method rather than a can: steel wool to pack the gap, foam to seal over it, then scissors, a push tool and gloves in the same box. That is the order this page recommends for rodent work, where foam on its own gets gnawed. Against it, everything a buyer could check is missing so far: no data sheet or safety sheet for this foam, no gap size, a B3 line with no standard named, no marketplace listing, and not one review on its own store when we read it. The page also disagrees with itself on the kit sizes.
Still open
- No data sheet or safety sheet published for this foam; the store FAQ refers to "the SDS" and links none.
- No gap size stated, only an expansion of 2 to 3 times.
- Not on Amazon or Walmart as of October 18, 2026, and no reviews on the BEEST store yet.
- The listing does not say what the wool is made of, plain or stainless steel.
Documents on file
- PAGE BEEST store product page no date or revision printed read 2026-10-18 The size picker calls the 3-can kit a "whole-floor pass" and the 4-can kit "a few entry points"; the FAQ on the same page gives the 3-can kit to "a handful of gaps" and the 4-can kit to "a typical whole-floor pass."
Jobs where a can from this category is part of the answer
These pages name the category rather than this particular can. Each one sets out the constraint that decides the product for that assembly, the code section that applies, a worked quantity example, and where foam is the wrong answer.
- Crawl spaces As pest block foam. Crawl spaces are where pest claims are sold hardest; the page explains why foam alone is not a rodent barrier and what the pesticide claims do not publish.
- Sheds As pest block foam. Sheds get mice. The page explains what the pest claims do and do not publish, and why hardware cloth comes first.

A safety data sheet or a brand page is published, no technical data sheet found.

Can the pest block claim on this can be checked? From the records
This can claims no pesticide, so its claim is the barrier itself, and the figure that would make it checkable is the size of gap the wool and foam are meant to close.
