Q:I have an approximately 1-1/2" hole in a shingle and plywood on the exterior of the second-story of my home, and wasps have built a nest in the void between the interior and exterior wall and access my basement from the void. Will this product work?
by|Sep 23, 2023
1 Answer
Answer This Question

A:  Hello BillyBob - It would be difficult to use to this application. It would be better to repair the the plywood and the shingle instead of using the Great Stuff™ Insulating Foam Sealant. Holes in walls are difficult to repair with Great Stuff™ Insulating Foam Sealant difficult because the foam tends to just fall into the void in the wall.

    Q:Can you use it with vinyl

    Answer This Question

    A:  Hello Red - If you are talking about repairing vinyl siding, there are better products for this then the Great Stuff™ Insulating Foam Sealant. We would not recommend the use of the Great Stuff™ Insulating Foam Sealant for this.

      Q:How do you remove the smart dispenser part if you don't want to use the entire can at once? I got one & it wouldn't come off and kept spraying everywhere anytime it got bumped. Doesn't seem to be a way to lock it to stop it from spraying. Made a huge mess

      1 Answer
      Answer This Question

      A:  Hello ZJDiy - The Smart Dispenser™ is designed to lock on to the valve of the can. If the Smart Dispenser™ doesn't, it can "helicopter" off releasing the foam in the dispenser. The Smart Dispenser™ should only release foam when the trigger is pulled, that is what opens the orifice allowing teh foam to exit the dispenser. Bumping of the can or even the dispenser, should be causing the foam to come out.

        Q:Can bees chew through this product
        by|Sep 11, 2023

        Answer This Question

        A:  Hello Timm - Yes, if any insect, rodent or other pest is determined enough they can get through it. The Pestblock product is more resistant to this than the other Great Stuff™ Insulating Foam Sealant formulations.

          Warning: Picture on front wrong!
          Great Stuff is GREAT STUFF! And I like that the 'Bug Version' has a sealing dispensing straw - so the can does not 'brick' itself quickly -- you can use the one can all day (and maybe even the second day). However, I do use acetone to keep the spout clean. ONE CAVEAT: The picture on the front is misleading. It makes it look like you can hold the can upright and dispense the foam. WRONG! This will cause *ALL* the gas to escape and leave you with a useless can. ALWAYS HOLD THE CAN UPSIDE-DOWN!

            "Smart Dispenser" failed almost immediately
            New can with a 2024 expiry date. Nice and warm, well shaken for more than 2 minutes. Installed Smart Dispenser to a snug fit. Upside down, start with slow press and foam comes out as expected for 3-4 seconds before I stopped to adjust. Smart Dispenser seems loose. I tighten it, and get a second run of a few seconds out of it. Smart Dispenser is loose again and foam is coming out around the base. Now nothing comes out. Returning tomorrow for a product that does not include a Smart Dispenser.

              Not for mice!
              Definitely not intended for larger pests as they can chew right through it. Bought because two workers recommended when they saw me looking at mice products. Very disappointed.

              Hello Freya,

              We are sorry to hear that our products did not work according to your expectations. 

              Great Stuff™ Pestblock Insulating Foam Sealant is a barrier to stop pests from having immediate access. 

              The following steps may further assist in creating that barrier:

              1. Fill the gap with Great Stuff™ Pestblock
              2. Apply a small screen or steel wool over the uncured Great Stuff™ Pestblock
              3. Once the first layer is cured, apply another layer of Great Stuff™ Pestblock DOW

                Just use newspapers instead
                Couldn’t get it to come out of the can. Almost no pressure, and what little bit did ooze out was almost entirely around the base of the nozzle (and yes, it was throughly shaken before use). Also, you will literally need a magnifying glass to read the instructions which are printed in tiny white letters on a light green background. Save your money and use something else.

                Hello Squirrelslaughing - We are sorry to hear that our products did not work according to your expectations. Best if Used By/Expiration date information can be found on the bottom of the can. As with all items sold through retailers, product should be returned to the place of purchase for exchange or refund.
                Sound like either an expired can of product or defective. DOW

                  Keeps Pests Out!!
                  [This review was collected as part of a promotion.] I am loving Great Stuff Smart Dispenser Pestblock.. 1 12ounce can equals 19 tubes of caulk..It can be used indoors or outdoors and is sandable and paintable..It keeps insects out and contains no pesticides but has a bittering agent..The dispenser is very precise and no worries about drips..Great Stuff Smart Dispenser Pestblock Gray dries in 10 to 15 minutes and is ready to trim in an hour..It also has all direction dispensing which made applying it so easy and fast.. Great Stuff Smart Dispenser Pestblock works and I so recommend this.

                    Easy to use
                    [This review was collected as part of a promotion.] This pest block work very well. I used it to keep bugs out of my shed and there has been a huge improvement. All you need to do is shake the bottle and aim in the designated gaps. The can shoots out a foam and slowly starts to expand till it hardens up and drys. Overall I would this product works very well.

                      Pest block works!
                      [This review was collected as part of a promotion.] We have had an ant problem in my den every year this time of year. I decided to use this pest block on the outside perimeter base to see if it would prevent them from entering since I was not sure how they were getting in. Since adding this barrier, I haven’t seen the ants. Please be sure to wear gloves when applying. It is very sticky! Easy to apply, but it does foam you a bit after application. But does exactly what it says.

                        Fills in the gaps perfect!
                        [This review was collected as part of a promotion.] I used Great Stuff Smart Dispenser Pestblock on the exterior of my home where i had a few gaps that i needed filled. I would get spiders, earwigs and other bugs in the house & I knew where I had some openings. I went around the exterior of my house and found possible openings and used this foam. The can & nozzle were easy to handle and it foamed up quickly trouble free. I had a rag on hand to wipe up any excess foam, but there wasn't much. The straw on the dispenser is tapered at the end nicely, so you can fit it in tight areas. I used it behind a dryer vent that wasn't flush to the stucco and it filled in the gaps very well. I would recommend this, and I would get this again to do areas on the inside of my home!

                          Great product
                          [This review was collected as part of a promotion.] My fiancé was very excited to try this. We live in the woods for the most part and have bugs, animals and mice lately. This was such a help plugging up all those spaces you don’t want to go overboard with trying to fill with other products. We also don’t like to kill the animals. So it’s awesome for all involved. Ty!

                            Definitely "Great Stuff"
                            [This review was collected as part of a promotion.] I got the Great Stuff smart dispenser Pestblock..I sprayed around my foundation where the siding connects to the foundation block. My flowers has little ants on them so this really helped with keeping them outside and not coming inside. Really easy to spray and control the amount. Highly recommended by me.
