## 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.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Seems to work quite well.
  

*by R***E on Reviewed in the United States on November 2, 2019*

The ratings ask about flavor?  Seriously?Anyway, this should be combined with some copper mesh because a rodent that has been coming in through a hole will dig out soft foam to re-open the hole.  If it hits sharp copper mesh that is stuck in place, that should stop the rodent.  For rodents new to the neighborhood, foam that expands to stop air flow and the aroma of food from coming out the hole should keep them from being attracted.I poked copper mesh in to the center of the wall, then sprayed foam in from both sides.This stuff continues to expand for about 10 minutes after application.  It is easier to trim back flush with the wall while it is still soft, but that is a bit of a gooey mess.  Bring paper towels.Be ready to do all your holes in one session because the nozzle will plug up when it dries.

    Works nicely once you figure out how much to (not) spray
  

*by P***R on Reviewed in the United States on July 17, 2019*

Spray foam is tricky if you have never used it. I got it all over the place, didn't get enough some places, and got too much other places. But this product was consistent, curing into solid and tight material. I used it with light copper mesh. I was able to spray through the mesh and then spray over the mesh. Take that, Roof Rats!By the way, I used the one can in three separate sessions by immediately cleaning the straw with about 1/4 cup of acetone (from the hardware store) in a gallon plastic bag (seal the bag tightly.) You also need to pour a teaspoon or so into the top of the can after removing the straw.

    Dealing with rodents
  

*by A***R on Reviewed in the United States 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.
