  • Perfect
Size: Pest Block 13.52 oz Color: Pack Number of Items: 2
I didn't get to use it right away so once everything was ready this sealant was used in more than 10 suspected holes. Haven't seen any mice for a couple of weeks now.

I started spraying this stuff and came back and when I did it was like an explosion of petroleum-chemicals in my wall. Did the job but not a good idea during food prep.

  • Seems effective
Size: Pest Block 13.52 oz Color: Pack Number of Items: 12
Any spray foam is going to be messy but this performed as well as any of the spray foam barriers that I have used. It does smell like moth balls, so I would only use it for exterior purposes. One can seems to go a lot further than other well known brands.

  • Works well
I used this to air seal my crawl space. Works very well. I payed $69 for 6 cans, and I just checked and it's almost $100 for 6 cans now. Inconsistent pricing.

  • Defective product
4 of the 12 cans sent are defective, and will not release any foam whatsoever. But Amazon would not replace the item due to the order being at the end of august. I was waiting for my new building construction to be completed. So basically there saying. You just use all 12 cans within 30 days to have any type of warranty replacement. In the past 5 years I’ve spent over $25,000 with Amazon. So they are losing a loyal customer over a $40 product warranty ... show more

  • Absolutely unbelievable expansion!
Size: Gap Filler 25.3 oz Color: Pack Number of Items: 2
Let me just say this… if you are used to the old school spray foam from even a decade ago… this stuff is 25x better and a little goes a LONG way. It’s easy to apply, but do not think this stuff doesn’t expand, because 30 minutes later you will see what it can do! I side this to fill various gaps ranging from 2-8 inches and it works fantastic. I will definitely purchase this again. ... show more

  • What a mess
Size: Pest Block 13.52 oz Color: Pack Number of Items: 3
So yeah it works. It’s just not the best concept for a trigger nozzle. It’s runny enough to plop out/off anything you apply it to, and so sticky you wanna kill yourself after you get it on your hands. It turns a nasty color over time, but once hardened it does keep a barrier for insects.
