Please also note that this is a ridged foam and using this foam around a window frame could bow the frame, if this is a concern please use the Window & Door foam.
Please keep in mind if this area is going to be exposed to UV light, even indirect sunlight, it will cause the foam to darken to an orange or reddish brown color in a matter of days or weeks. Constant exposure to direct sunlight will eventually cause the foam to break down and crumble apart. The foam must be painted or coated with a UV resistant coating if used outdoors. Read Less

Hello Alex, I’m Newf from the Home Depot’s how-to Community. Thank you for your question.
Yes sir. That is exactly what this product is designed to do. If the hole is actually in the glass, I would either use a clear silicone caulk instead or just replace the glass.
I hope this helps,
Newf.

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.

Answer: 
Until solid, you won't want anyone to ingest it , breathe it, or get it on your skin. It contains no pesticides, but you do need to allow 8 hours for the foam to set up and the vapors to go away. Keep the area well ventilated. Once solidified, it is safe.

Answer: 
GREAT STUFF™ Insulating Foam is non toxic once the foam has cured a full 8 hours. You will want to keep away from children during the curing stage and make sure to wear gloves, protect your skin, and also wear protective eyewear. This product is extremely sticky. When dispensing the product you will want to make sure there is air flow throughout the area.

I have sprayed this upside down and had success with it in short bursts. The can recommends you do this to clear the nozzle but it will work and put the foam where you want it if you limit the amount you use at one time.

Answer: 
Great stuff is meant to be sprayed with the can inverted(upside down). trying to spray it with the can up -right will cause the foam to spray erratically or not at all. There is great stuff Pro which can be used up- right. That requires you to purchase a reusable spray gun kit though at considerable expense.

Rated 4.0 out of 5 by 108 reviewers.
Rated 3.0 out of 5.0 by Carpenter bees Maybe it's good for ants or little spiders but not good for carpenter bees. I have some really annoying carpenter bees boring holes into my rake board. I called an exterminator and he wanted $600 to stuff the void with a mesh after spraying. It sounded like too much just to stuff, so I went with this. Not only did it not work but it ruined my siding. Now I have to spend money to have the rake boards replaced as well as some pieces of my siding. $600 doesn't sound too bad now. I guess I can recommend this for other types of pests. Can't if it would work for them. Good luck. June 1, 2016
Rated 5.0 out of 5.0 by 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! May 31, 2016
Rated 5.0 out of 5.0 by 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. September 14, 2016
