Pest Block Spray Foam - (2x12oz) 100% Odor-Free! Mouse - Rodent Repellent & Strong Polyurethane Mouse Blocker Foam Sealant Use Wall Foam Filler for Holes and Cracks, Over Paintable- 2 Pack

this stuff works and is easy to use. Make sure to use gloves

This stuff worked great, though I'd suggest wearing disposable gloves when applying it. It goes into crevices very, very gooey and sticky, but dries quite hard and firm. As it smells like mothballs, no creatures are keen to nibble at it to gain re-entry. Very, very effective!

Arrived undamaged and easy to use, but that first night mice came to chew it out.We had a duct that went through an exterior wall that had rodent evidence on the outside of the duct/inside of the wall. (Around the duct pipe?)Anyways, we removed the pipe, cleaned the wall out, and put a wad of paper-towels soaked in lemongrass, cedar, and citrus essential oils in the wall, then foamed around the new duct. Very little foam was exposed to the outside, most was in the wall, around the pipe. The next day the cover was going to get put on but we wanted to give the foam 24hr to fully expand and then trim up any excess. Over night, the mouse came back and tried to re-establish his home ownership, hah.The next day, we cut out the pipe, cut out foam, and repeated the full process and installed the steel cover installed that afternoon. No further issues.If this was as the only barrier against rodents, it would not have worked; I think it works well as foam, but doesn’t deter rodents as well as we had hoped.Ended up that it was all covered in our application and it was fine! So worked out.

I was having a bad year for mice getting into my basement so I sprayed this stuff into every crack, crevice, and area around any pipes, tubes, cables going into my house. I haven't had a single mouse since. This is the first winter I can say that in ages.

Not sure if the stuff works yet but I can say that the smell is so bad I threw the second can out without even using it. The foam dripped off everything as I sprayed it. I had to use the nozzle to try and move it around.

This product is easy to use and sets up strong; however, if you are planning to purchase this product but do not plan to use the entire can during the initial use, then be sure to purchase the hose cleaning system. Once the foam sets up in the tube it is not coming out easily. With the cleaning system you can use the same can repeatedly.

Don't expect much. I thought this was similar to other expanding foams. It is not. It does not expand much, nor does it fill in gaps well. There's hardly anything in the cans and it took me both canisters to barely fill in a 12x6 hole in my attic crawl space. Better off with regular expanding foam spray and a bar of Irish Spring soap or cayenne pepper to keep critters out.

Doesn't adhere well to the surfaces when spraying up...just plops back out
