Is this foam harmful to adults and kids?

Asked by: Anonymous
To the best of my understanding, it is toxic if ingested while wet and safe when dry. But this is true with many everyday household products as well.

16 oz. Pestblock Insulating Foam Sealant is rated 4.0 out of 5 by 111.
Rated 5 out of 5 by from Perfect for stopping mice We had a small mouse problem when we moved in and they were smart enough to avoid the traps. What worked? Great Stuff Pestblock Insulating Foam sprayed into all holes and gaps between your floor surface and baseboard. The foams fills the gaps perfectly and hardens overnight. So worth it. If you have exposed brick, you’ll also have holes and cracks in that. Fill them with the foam and cut away the excess after the foam has hardened. I got pretty OCD about finding every crack and hole in the (rather large) apartment and filling it, including in my laundry/utility room and all our closets. I have yet to see a mouse dropping for the last year, even though I can sometime hear them inside the brick party walls. These bottles are one-time use, so be sure to identify and clear all your holes and gaps before you start spraying. Also, this stuff is really sticky so be sure to avoid getting it on carpet and wear disposable rubber or latex gloves.

Rated 5 out of 5 by from great stuff for sure I have read the people who have had trouble with this or low expansion. This is not the largest expansion but I have had great luck with as it expands alot. I have filled holes way over the 1" that is recommended. If it comes out like silly string you either had it outside and it froze, or more likely you did not shake it enough. You have to very vigerously shake the can for about a minute to get best results. This also spreads the pest block material around more in the can to be more even. If you want a product that you can reuse the can get the pro stuff. You will be able to reuse the can and the nozzel if you clean it out after each use.

Rated 5 out of 5 by from Great stuff Worked well for me. I've used other products from this company before and was happy with it

Rated 4 out of 5 by from Works Great for Stopping Mice. My house has been invaded by mice. The exterminators (two different companies) came and laid down some traps. Zero captures for theme. I have exterminated 7. As for the foam, mice won't touch it. They get angry and move. The price is high. If you buy a case, a little discount would be nice. The foam is easy to remove from the floor or wall aft it drys but don't get it on your clothes or hands. It's a struggle to remove. Biggest complaint, the foam doesn't always stick to a vertical hole so I suggest checking all vertical cracks you fill. The application tube could also be longer.

Rated 5 out of 5 by from Learning curve, but great product There are a few things you should know before using this on a project. 1) Wear safety glasses. Do not skip this. If it gets in your eye it will be a huge disaster. 2) Wear disposable gloves. 3) 100% Prep all area that you want to use a can for. The maximum "rest" you get is about 3 minutes before it starts to harden in the spray portion of the application tube. Once it does harden, that can is done. 4) It initially expands to about double the sprayed area, but after an hour is about triple the initial spray. 5) So far bugs haven't come near the stuff. It has worked well. It doesn't smell (which you might expect from an anti-bug product). 6) If you are smart about how much you are using then one can would probably make it around the base of a two car garage.

Rated 5 out of 5 by from No question, the best stuff to close up holes made by rodents Worked great, use gloves for sure because this stuff is really sticky. Really happy that the house no longer has rodents!

Rated 3 out of 5 by from Confusing product I'm really not sure why this version of this product is any different than the regular other than its more expensive. Real the label, it looks like there isn't any insecticide. So why is they better than plain great stuff for keeping pests out? I have no idea. Also, check the expiration date on the bottom of the can. I purchased a can of great stuff that had expired and you could not get any foam out of the can!
