## Description

Great Stuff 11000714 Stuff Pestblock 12 oz Insulating Foam Sealant, 1 12 Ounce, Grey

Review: It seems to be true that rats don't like chewing this stuff. - Works freat. Really sticky. If you get this stuff on something, it ain't coming off without a fight. Supposedly, it has a bitter taste rodents don't like. I have never tasted it. I'll take their word for it. All I know is, I installed it 2 months ago, and none of it has been chewed. The only downside is, once you install the spray tube, and start using the foam, you have to use up the whole can. If you let it sit over night, you will not get any more out in the morning.
Review: Great at filling cracks - This stuff works great, and I plugged many holes in my rental property. I have no idea why desertcart asks for the flavor in the reviews, no one should ever taste this. One thing everyone needs to know about great stuff, is that it gets on everything, so always use gloves with this. Also I always use a full can at once cuz I've never been fully successful at using it later, it always seems to harden at the can.

## Questions & Answers

**Q: Whats the difference between Pestblock foam gap filler and regular Greatstuff foam gap filler?**
A: Pestblock has a non-toxic bitterant in the foam so the rats don't like to chew through it. Regular foam is soft and tasteless so rats can easily chew through it to get into your house or basement.

**Q: Can you buy replacement straws?**
A: I saw straw cleaner at Home depot (11/5/15).  They claim it's for their professional line, but I bet it will work.

**Q: does this expand as much as other products?**
A: Yes, it expands just about the same as the other foam products.

**Q: What about its odor? I'd hate to be driven out of my home by an unpleasant and  lingering odor. It would be murder to remove.**
A: I have used it in my garage which I shut permanent to keep the rats out.  I have smell anything except a slight musky odor of rat.

### ⭐⭐⭐⭐ Dealing with rodents
*by A***R on March 10, 2015*

Definitely easier to use than steel wool or copper mesh for blocking small (less than 1 inch) mouse holes. That being said, DO NOT ASSUME blocking the holes will resolve an infestation, or you'll be reporting what a lot of people here are -- determined mice ate through it in no time. Here's what you do to put an end to the problem once and for all; (1) Don't clean up mouse droppings. These are "hotspots" and the mice will return to them if they're left untouched. (2) Get some poison blocks (I like "Havoc XT") and three inch wood screws (you might need some washers). (3) Put three Havoc XT cubes on a woodscrew and secure it in to the floor/wall (whatever) where the dropping are. (4) Replace the cubes once a week until the mice stop feeding; it may take up to a month. In bad spots, you might need to put 2x or 3x poison. (5) Search the area around your hotspots for entry points... plumbing pipes/drains are a major culprit, but I've seen bad/amateur electrical work on exterior walls that punched right in to the vent space. (6) Fill holes/gaps *generously* (push the applicator straw in to the hole, spray for 2-3s, then continue spraying while slowly withdrawing. The can is single use, so go ahead and use it all. You'll want to wear gloves and safety glasses. as the stuff is impossible to get off your skin. If the mice never stop feeding, you're likely killing the neighbor(s)' mice as well, and you'll have to look at more drastic barrier methods (rodent control wire mesh). If the "hotspots" are on an interior wall (usually the wet wall where the drain stack is) the mice are coming up from the basement (or other apartments). If the hotspots are along the exterior walls, you're more likely to have mice coming in from outside.
