20 Best Caulk For Mice (2022 Updated)

The chance to review this product couldn’t have come at a better time. A few months back, I opened my “glassware” cabinet and a circular cut crystal vase that belonged to my Mother, hit the floor. I didn’t see any damage so back in the cabinet it went.

Well. my wonderful husband bought me a “for no reason” (lol) bouquet of mixed flowers yesterday. I went right to this vase, filled it with water and put the flowers in. Yep, a steady stream of water was slowly dripping from the side of the vase.

I found that there was a hairline crack in the middle of one of the circular cut glass edges that was about an inch long. I hate those liquid glues that always make everything look messy and “fixed” so out came the Flex Tape.

This is a waterproof tape that feels kind of stretchy or rubbery. I had the clear variety so this was perfect. I cut a piece to cover the damaged part of the vase then put water in the vase to test it out.

Sure enough, NO LEAK!! In seconds, I had repaired a 50 year old vase with such an easy product to use. Because it was clear, unless you knew the damage was there, you wouldn’t see the tape, AND, I did it myself with no sticky glue mess.

I was thrilled that it worked so easily and quickly. The Flex Tape can be used on wet or dry objects and even underwater. (The pool liner). I highly recommend this product to everyone who wants a permanent repair for their projects.

It was important that the product be stainless steel, not steel wool, which most of them are. I used it as extruder in my garage door’s bottom seal. Was easy to work with.

Easy to cut & work with. Measure area to be used in accurately before purchasing. Then order more. Doesnt rust as quick as regular coarse steel wool.

Does not work. Put it in a hole in the soffit. The squirrel pulled it out and spit it on the ground.

Tomcat Rodent Block is an effective way to keep rodents out of buildings. Use on cracks and crevices in foundations or anywhere else around home. I used around pipes coming up through my floors under kitchen sink.

I also used in my crawl space under house. Product not only keeps out rodents, it helps insulate home sealing out drafts. I have used around my home any place pipes or wires have been run, This blocks places were rodents can get in the home.

I recommend following directions because product can be messy if you don’t follow directions.

I recently tried Tomcat – Tomcat® Rodent Block Expanding Foam Barrier on different areas of my garage i was having problems with rodents. This spray filled the gaps and cracks I had and it kept the mice from coming inside my home.

The expanding foam worked perfect for me to block the mice from coming inside my garage, It provided a long-lasting, airtight and water-resistant bond. As the product states this foam can be be trimmed, sanded, and painted if you so desire.

You can also use it on crevices inside and outside your home, including the garage, attic, basement, and foundation if you so wish. Since my problem was the garage I used it on that and I was glad I did.

The expanding foam barrier is pesticide-free and it worked perfect to keep the mice i had coming into my garage. I would definitely recommend the Tomcat® Rodent Block Expanding Foam Barrier to anyone that is having a rodent problem.

I wish i could give it more than 5 stars because this product is the best rodent blocker around.

I purchased a can at Lowe’s. Came home, read the instructions and immediately used the foam. There was a crack all the way down the straw and the foam went EVERYWHERE! All over the floors, cabinets, my hands, and my jacket.

What was supposed to be an easy fix turned into a disaster. I had to scrub for hours. Throw away my favorite jacket. Scrub my hands raw and still they were sticky. So I threw the rest of the can away bc its useless without the straw.

One squirt of the trigger was a disaster. I should have purchased regular spray foam that doesn’t require the straw.

Stays soft, peels up right away. Would not recommend. Was more expensive and lasted 1/2 as long. ………………………………………………………….

Having started using this more than several decades ago as a sealant when we manufactured custom log homes. I have always been very impressed as to the far superior flexibility coupled with adhesion to a wide range of surfaces under difficult conditions.

This is a good product as I had used it before. However, this tube I received was obviously old and it did not flow out of the tube and stick to my surface as did the previous tubes I had used.

I used Tomcat® Rodent Block Expanding Foam Barrier last week to seal a hole on the outside of my brick home. I was having a problem with field rodentsenting in my home and garage. This product works as advertised to seal.

The foam seals off cracks quickly in places that rodents can enter. I highly recommend for all home owners. Easy to use , the scent is ok, and it seals quick. Just follow directions for the effective use of the product.

I used it last week and it is still. sealed, no issues with rodents rating threw it. It appears it is holding up well.

I purchased this a couple of weeks ago because I saw rats dropping on my roof next to my air conditioner and also noticed an exposed hole (no wonder I heard some noises in my attic) so I waited until the day light & cleaned the area by sweeping the dropping and used this product (proven to be later on a winner).

I was checking on daily bases and to my surprise no more dropping and the small hole is tight sealed. Tomcat rescued me from these ugly intruders. I recommend this product cause it’s proven to work.

I bought this stuff to block ant ingress to silverware drawers in my kitchen. But reading the instructions is virtually impossible due to the tiny font on the can, even with reading glasses. Attaching the wand was the really problematic part: was I supposed to push down on the nozzle to attach it? That created a mess, since the goo began to spray out.

Screwing it on seemed to work, but there was nothing I could read in the instructions that indicated that this was the preferred method. (Might have been there, but I can’t read font that is too small for the “Reading Center for Ants.

“) The foam itself sprays on in an amorphous mess, and god knows if it will stay in the half-inch mouse entryways above my drawers. We shall see. And now that I have use the stuff, will I be able to again? Or is the nozzle clogged and sealed? Finally, the spray process was so imprecise that I got the stuff on my pants, which are now in the washing machine; hope they aren’t ruined! There has to be a better way to design the can and spray nozzle.

I can’t use as I can’t read the label. It’s small print in yellow on a light lime green background. I really want to use it but must find a low vision person with a magnifier to read label.

Shipped quick . Great price for the product !

This was pretty simple to use and the results came out way better than I expected. I used this sealant to reseal around my bathtub. I’m glad that it came in white, so the final project looked wonderful.

Also, that its mold and mildew resistant was great as it’s being used in a wet environment. The precision of the applicator nozzle made it come out really smooth and precise. I did not need to paint, but it’s good to know that it could be painted in just 15 minutes time.

That’s pretty awesome. I’m looking forward to using this again for my next home project of sealing the windows.

I purchased this product because I did not want to cope with extended drying time on a kitchen counter. I may have underestimated the time that I needed to smooth each gap/line. I was frequently challenged to complete tasks before the product dried.

With a lot of rework, everything turned out great but next time, standard drying should be fine!.

Easy to apply and achieve professional results, looks great. My issue with this product is if you ever have to remove your trim. recently made a change to lower profile base and even when first scoring with a knife this stuff removes the layer of paint AND the drywall paper leaving a loose paper edge that is difficult to skim coat and sand level.

Good if you don’t plan to change your trim in the future.

I only use this NP1 product for any concrete joint sealant. A longtime professional friend recommended it to me many years ago and I’m always impressed on how well it sticks to the surface, smooths out, and how it lasts forever.

This is a very difficult product to find and was surprised when I recently found that I could get it online through Walmart. This is what the people “who knows what is best” use on their own projects.

Also, a hint, once the product starts to dry you can buy an aerosol can of window cleaner (no ammonia) and spray one it on sealant and then let your finger run down the seam for a nice smooth professional finish with NO mess or stickiness.

I’ve used this product for years but I have always purchased it from the local supplier this time I needed white and they didn’t have it so rather than wait for them to order some and pay more and pay shipping I purchased on line I’m sure glad I did the lubes are fresh and the product came out of the tubs with ease.

This stuff is the best, it sticks to surfaces and expands and contracts with wooden surfaces, when it seals it seals.

I have been using DeTour Gel for rodents for years. It is a great product in that it is applied easily and I use it in conjunction with pre-baited rodent traps. You have to know first what type of rodent you are dealing with because based on that you can set the right size snap trap.

As an example, you would not want to use a snap trap that is for mice to catch a rat and vice versa. It is waterproof, food grade quality, non-poisonous with its main ingredient of capsaicin and other proprietary ingredients and is not harmful to humans, pets, or plants.

DeTour Gel is easily applied and in conjunction with snap traps, it wil make it easier to catch rodents on your traps because you will have to place the snap traps and the DeTour Gel in the runways or pathways that the rodents are using.

As they get the DeTour Gel on their bodies, they will stop to groom and as a result ingest it causing a severe reaction that is similar to humans eating a very spicy salsa with chips. If you are not used to the potency of the spice, you will quickly be gasping for some sour cream or a glass of milk to calm the burning sensation the spicy salsa has in our mouths.

This same or similar reaction is experienced by the rodents and since you have your snap traps nearby armed and ready to kill, you wil be able to catch the rodents on your traps that much quicker. The advantage of DeTour Gel is that it also acts like a repellent and rodents will not cross the path of where you have applied the DeTour Gel.

This also has an effect on rodent control as you also must seal off all entry points to deny entry access into the building. As always, you can contact your local pest management professional to help you with your rodent management.

As a final thought, you have to apply DeTour Gel in a non-porous surface, otherwise it will be absolved by the surface you are applying the Gel to and it will not work. It does last on the surface applied for many years undisturbed.

Therefore you must follow up on those areas you have applied it to ensure that the product is still there where you intended it to be.

I used the Detour Gel as part of an integrated program that I created to resolve a decades-long mouse infestation in a mountain cabin at a cow camp. Detour Gel has the same active ingredient as bear and pepper spray, but at lower concentrations.

It does sting if it gets on the skin, so I assume it would bother a mouse or rat pretty significantly. It is food grade, EPA approved and FDA approved. The house is a 70 year old log cabin that has had decades of neglect.

The logs and chinking have dried out, leaving many entrances for the mice to come in. It is only used a few months during the summer, giving the mice ample opportunity to take over during the winter.

Each summer, someone would bring up a big bucket of poison bait and toss it all over, including under the cabin, but the mice were reproducing too fast to have much of a difference. The classic rebound effect.

It was so bad that no one wanted to go up there anymore. The bait and trap solution was clearly not working. Until I found all the entrances and drove them out and sealed them up, there would always be a problem.

I wanted a solution that would allow me to a) drive all the mice out; b) identify and seal up all entrances; c) create a “permanent” solution; and d) reclaim the cabin for human habitation. People told me it was impossible to get all mice out of an old house like that because there were so many cracks that we can’t detect that the mice can.

But I was undaunted. My first step was to use rodent tracking powder to find the entrances, where the mice were going once inside, and where they might have nests inside. I discovered about 40 nests inside the living areas – more in the crawl space and attic.

The second step was Detour Gel. I didn’t want to remove a mother and leave behind a nest of babies to die and decay someplace I could not detect or reach and create a smell. I also didn’t see the need to kill them, just move them out into nature.

I hoped the Detour Gel would create a strong enough deterrent that they would choose to move out of the building, but not such a strong deterrent that they would not go back inside to grab their babies and depart.

I don’t know if that strategy worked or not in terms of them bringing their babies with them when they left, but I didn’t find any evidence – physical or odor-wise — of babies left behind. The third step was to seal off the entrances.

Then repeat until there is no more evidence of mice coming into new entrances. More specifically, this was my process and how I used the Detour Gel: 1) When I first put down the rodent tracking powder, I discovered tracks leading to a crack in the corner of the living room where the fireplace met the wall, in the opposite corner, in the bathroom, and in one of the two bedrooms.

2) I used a cheap sponge paintbrush to “paint” Detour Gel around each crack/gap/hole so that the mice would need to come into contact with the gel to get in or out of the hole. 3) I used some cheap floor tiles from a home improvement store to draw a 2 inch by 6-inch rectangle on the edge of one side of each floor tile.

If I were trying to get rid of rats, it would be about 3 or 4 inches by 12 inches according to Rentokil, which is a large pest control operator that private-labels this product. I assume Rentokil suggests the rectangle because once the rat or mouse runs across the gel and is inside, they have to run across one more line to get out, so they get a double dose.

The company recommends a zig-zag. I assume either would work. 4) I placed a number of these floor tiles all along the wall where the tracking powder indicated the mice were running. If the tracking powder indicated they were not running near the wall, I placed the gel-covered tile over the path identified by the tracking powder.

These were placed about every 10 feet, although Rentokil recommends 5 feet for mice and 10 feet for rats. I didn’t have enough product for every 5 feet because I was placing it around a 900 square foot cabin.

5) I found rodent tracking powder leading into the back of a vintage propane fridge, some recliner chairs, the back of the stove, the kitchen cabinets, box springs and mattresses, and some other places, indicating nests.

In order to get them to vacate the nests, I ran double circles around the base of the fridge and chairs and vacuumed up the nests in the cabinets, painted the back of the stove with gel, etc. I wanted to make sure the mice would have to come into contact with the gel if they wanted to return to their nests.

6) Leave it for a few days then seal up the entrances. Rentokil states you will see enhanced activity for the next few days. What they do is put traps down, but I didn’t want to risk killing a mother mouse and leaving her babies behind.

7) Put more rodent tracking powder down to find out the new entrances. 8) Pick up the floor tiles with the Detour Gel as appropriate and move them to be in the path identified by the new tracking powder trails and paint more Detour Gel on the entrance.

Where you think it is appropriate, you can even use the Detour Gel to seal up an entrance. But a mouse will not leave through a completely sealed entrance and I knew they were living inside and I did not want to entomb any if I could help it.

Detour Gel will also only last a certain period of time if the entrance is a non-porous surface. It can last over 5 years if inside on a porous surface. 9) Wait a few days to retrain them so that they understand coming into your space from this point forward is going to be an unpleasant experience.

10) Use a permanent seal to seal up the new entrances you discovered. 11) Put down more tracking powder and repeat until the tracking powder shows either a) no new activity, meaning they are all gone or b) the tracking powder shows them going to a nest inside the house, but not to any new entrances.

If a, you are done, son! At least for now. You need to stay on alert, because if they are aggressive, they will search the outside of the house looking for new entrances. So keep the tracking powder down to alert you to any new breaches of your fortress so you can get on top of it and nip that problem in the bud! 12) If the tracking powder shows them going to a nest inside the house but all entrances are blocked, then the remaining mice are probably entombed and you don’t want them dying in there.

This happened to me in the crawl space at the end. In this case, I put down a humane aluminum Live Catch trap with some nuts and seeds, trapped the remaining mice, and re-homed them a few miles away in nature.

It took me about 3 or 4 days to catch the remaining 11 mice – all of whom were now in the crawl space and not in the living areas — and rehome them. I might have been able to get all of them out without entombing them if I had paid more attention to the crawl space at the beginning.

Through this process, I found and sealed over 20 entrances into the crawl space, 14 into the living areas, and found over 40 nests in the living areas alone. There were many more in the crawl space below and the attic above.

I did find that they would look for ways around the gel. If I saw tracks in the gel, I never saw the second set of tracks, leading me to believe that it only took one crossing to convince them not to go near it.

There were times when I scraped used gel off of sealed-up entrances and reused it on newly discovered entrances because I was low on product and it was more economical. If you have a place where you cannot physically exclude them due to time, money, materials, labor or just the physical space, if you can create a gel barrier that they have to cross, you can create an effective block that they won’t cross that will protect your space.

If you have a porous material, like cement or wood, the product is good for a couple of weeks before it will dry out as the mineral oil seeps into the porous material. What you can do is paint some silicone caulk on the surface, let it dry for 30 minutes, then paint or spread some of the gel on top of the silicon.

I recently discovered I could have used silicone spray. That would have sped the process up for me and I could have done more permanent/5 year plus exclusion in the crawl space. Because when it’s on a non-porous material, like a floor tile or metal or silicone, it can last over 5 years in an indoor setting.

You can do this on places they like to travel, like support beams. You can also paint it on electrical wiring so they won’t chew, or plumbing pipes. One final comment on exclusion: they can smell-through and will push steel wool, copper mesh, and similar products out of the way.

They can smell through and chew through any expanding foam, including the ones for “pests. ” One solution is to use silicon caulk that they can’t smell through and copper mesh, which they don’t want to chew through and use the combination to fill cracks.

This will “glue” the copper mesh etc into place so they can’t push it out of the way. Is my problem solved forever? Until I can refinish the outside of the cabin and rechink it, my guess is they may find some extra vulnerabilities.

But with this solution, the game is now handicapped in my favor to find entrances quickly, drive them out and exclude. The cabin has officially been reclaimed for human habitation. Good luck!.

I highly recommend this product. I don’t know of a repellent for rodents, skunks, birds, ants that works as well and lasts as long. You can even put it on your hoses under the hood of your car! 100% food grade and FDA approved too.

I lather this stuff around a pile of bait and the rodents track it all over the usual hangout spots and contaminates them so they have to leave. Honestly, if you can’t fix your problem with this gel you are doing something wrong.

I bet my bank account that a rat exposed to this gel won’t cross over it again.
