Termidor FOAM

Termidor FOAM contains Fipronil, the same active ingredient as Termidor SC, in a RTU (ready-to-use) foam that is labeled for termites and ants. Perfect for spot treatments, Termidor FOAM expands rapidly creating a dry foam that can be applied in the voids, harborages, galleries, and nests where insects are found. The foam generated has an expansion ratio of 30:1. In about 5 seconds 1 oz. of product becomes approximately 1 quart of foam.

Termidor FOAM can be applied in and around residential and commercial structures; structural and non-structural elements that are prone to insect attack (such as fences, utility poles, landscape timbers, bridges, or under slabs); or insect harborages. This product can be applied from the interior and/or the exterior according to label directions. To access some harborages the drilling of holes may be required.

Termidor FOAM helps to fulifill the Localized Interior (LI) component of a Exterior Perimeter/Localized Interior (EP/LI) treatment (also known as PerimeterPLUS).

Termidor product features:

Advanced undetectable technology
Termidor is made from a revolutionary new nonrepellent or "undetectable" chemical technology treatment. That means termites cannot see, smell, taste, or avoid Termidor. Instead they contact, ingest, and share it with their nestmates. This is in sharp contrast to older liquid termite controls, which rely on repellent barriers that termites can find breaks in or avoid completely.

The "Transfer Effect"
Termites who contact Termidor transfer it to every other termite they in turn contact, in a unique process called the "Transfer Effect." And because Termidor is engineered to be slow-acting, termites have ample time to spread it throughout their entire termite population.

Better than bait... without the wait
Baits can take years to control a termite colony. Termidor begins working immediately to wipe out termites inside and immediately surrounding your home. Termidor is the most effective and fastest at completely eliminating termite populations--up to six-times faster than bait.

    5 of 5 stars  TERMIDOR FOAM
    By Roscoe in TIMMONSVILLE, SC on 03/02/2013
    Verified Purchase

    I had never heard of termidor foam and had reservations as to it's value. Folks, it works. We made a small hole in the driwall between each wall stud and pierced a hole in the insulation so that I could spray the foam into the airspace. Then inserted the tube through the hole and gave it a squirt. The foam expanded and the termites that I could see began dying. After a couple days, there was no more signs of infestation.

    I found their pencil hole entry and drilled it bigger. Then I put on gloves and put the foam in. It was easy and no more coffee grounds! A week later I found another area nearby with drywood termites. I did the same thing. It has been a few weeks and no more coffee grounds anywhere. This works!

    5 of 5 stars  Amazing product!!!
    By Diane in CT on 06/18/2014
    Verified Purchase

    I had a localized carpenter ant nest in a fully enclosed wall. The nest activity spanned a 4x5 foot area. After freaking out and receiving ridiculous exterminator quotes, I did some online research. I learned that the active ingredient in Termidor Foam, fipronil, is a safe and extremely effective chemical that works by direct and indirect contact. Even though the walls had fiberglass insulation, I was able to drill near the studs, and insert this foam into the voids. I only used one can for the the job. I saw results within 12 hours, and the problem was fully resolved within three days. I am thrilled with the effectiveness of this product, and am pretty excited that I was able to save $450+ by tacking this project on my own. Thank you for offering pro-quality pest control products to homeowners at very reasonable prices.

    This product works great . I used it just as spring was approching the end of February to spot treat troubled infested areas from the past YEARS and in two weeks the termites began to appear . Only this time they were approximately less than 1/10 the amount flying out as there were last year I was extremely pleased!!!! You have no idea what a relief that was now I will treat the barrier around my home. And hope it works the rest of the way to destroy those annoying chewers thanks!

    By Joann in Sebastian on 11/21/2016

    Someone mentioned I needed an actuator? It foamed up then turned to liquid and dissapeared. I thought it was supposed to dry as a hard foam. Not sure if I'll by this again. Don't know if this worked or not.

    Expert Response   Expert response:
    Thank you for your comments! The Termidor Foam can comes with the actuator; you do not need any additional tools to dispense the product. The product is an insecticide with a foaming agent, so it is designed to expand to fill voids and then dry clear, similar to products like hair mousse. Please let us know if you have additional questions or concerns.

  • 5 of 5 stars  Termidor foam in a beam
    By John in State College, PA on 11/05/2016

    A few years ago I noticed bits of gritty dust on our piano just under a ceiling beam. I sprayed a couple of times, but it kept happening. Then, last summer we were away and I returned to find about a teaspoon of dust on the piano. Tapping the beam gave a hollow sound along a six foot stretch, so I figured this was pretty serious. I acquired a tube of Termidore foam ($28.31) and, after drilling 13 holes (3/8 inch) horizontally and two upward holes into the beam section, I injected 7 ounces of fluid, which presumably foamed to 7 quarts of foam. After each injection, I held the nozzle in the hole for about ten seconds to force it to expand into the beam. 7 quarts turns out to be about 20% of the volume of the beam section, so yes, it was serious. There was no immediate visible result, but the next morning I found three dead adult carpenter ants and about 50 larvae on the piano. Over the next week, more dying ants emerged for a grand total of 33 adults and 70 larvae. I imagine there are many more corpses lying up there in the CORRIDORS OF DEATH. I still have 2/3rds of my Termidor in reserve to use if I see future activity. So far, I am 100% pleased. I have two suggestions for the provider: First, mention in the directions that you can clean up with water. Second, include a printed page containing the information that is on tube. The print on the tube is very small and was hard for my 80 year old eyes to read without a magnifying glass.

    I have been using this foam termiticide for several years now both in Ohio and Florida with very good results. It is very easy to treat the tunnels by drilling a small hole into the wood and applying the foam. It appears to be very effective.

    1 of 5 stars  Not for Upward Applications
    By N in Ocala, FL on 07/11/2016

    One of the base beams of my house had termite activity. Only the bottom part of the beam was accessible from the crawl space. I wanted to buy a D-Force HPX can and inject termicide in the holes, but I had concerns, because the spec says that can has to remain upward, so this means no spraying upward. Customer service recommended Termidor Foam, which has a flexible applicator. The problem is that foam is barely pressurized; it will not go upward. This was a total waste. That product is only good to spray downward inside a wall cavity.

QCan you help with the math for my Termidor FOAM application?
Interior wall, no insulation, 3” studs spaced 16” apart. So 1 oz. makes approximately 1 quart of foam. 1 quart of foam would fill how many cubic inches? In other words, how many quarts of foam would it take to treat a 12”H x 16”W x 3”D wall void? Do I need to fill an entire wall void from floor to ceiling if I’m just seeing carpenter ant activity at the bottom of the wall? Thank you for your input.


If there is no insulation in the wall then there's not many reasons for them to be in that wall void as the insulation would provide an area to nest. They may travel behind the wall voids but the main nest will not be behind it. They will most likely be using the studs as a food source and traveling up the sides of the studs. You will not foam the entire void, rather you will drill a hole close to the top of the ceiling/stud on either side of the stud. Once the holes are in place on each side, inject the foam into each hole for 5-10 seconds, allowing the foam to expand but slide down the sides of the studs where they would travel. If you are seeing them along the baseboard areas, drill holes every 8-10 inches apart across the area between studs, about an inch or 2 above the baseboard. Use the same injection rate for each hole and let dry. The Termidor Foam has some residual for about a month after it dissipates so if any are missed in the initial application the rest of the colony should be affected.

QHow long will the effects of the Termidor foam remains active if I inject the foam into the exterior walls?
I have the base boards removed and see the remnants of the subterianian termites. I plan on drilling holes into the drywall before I replace the base boards and have had a professional company treat the perimiter of my home with termidor. They explained to me that treating the perimiter of the house will also kill the ones that have already entered my home. I really don't belive that and haven't found that info anywhere on the internet.

ATermidor Foam will remain active for about 6 weeks when injected into the walls. Termidor Sc placed in a barrier around a home will kill foraging termites as they return to the colony....if the colony is not under the home (in most cases the colony will be out in the yard so this method does usually work). It is recommended that if you know where the termites are active in the wall void that you treat the area with a product like the Termidor foam just in case the main colony is under the house.

QHow do I get rid of termites in my kitchen cabinets
I have an infestation in custom kitchen cabinets that are only 2 years old. There are no signs of entry from outside the house. I believe they were in the cabinets when they arrived from the manufacturer. I contacted my insurance company and although not listed under exclusions, insects are not covered. My boyfriend is a custom home builder who can take the face boards off those that are still intact. I was away from my home for months returning to find thousands of dollars of destruction and I am at a loss on what to do. I read your reviews on the Termidor foam and saw one review saying it is not for use in kitchen cabinets. Please let me know if there are any options you can recommend?


 The Termidor Foam is definitely an amazing product and does well to transfer. That being said,  you would have to drill holes into the cabinets to inject it into the galleries the termites have created for it to expand through their tunnels and reach them. Honestly, we have many customers in the Bahamas that use our products (they have them shipped through freight forwarders) and its very common for you to have a variety of termites in your area that could have flown in from the outside and infested the cabinets. The only downside to the cabinets themselves is if they weren't pretreated before being assembled/stained from the people you purchased them from. If there were termites in them when they came from the manufacturer, the likely hood of them being in there this whole time with no signs of damage or kick out holes and dust until 2 years out is extremely slim. Cabinets aren't that thick compared to beams and supports of the structures of homes which can cause finding termite damage and activity signs to be less noticeable for longer. Normally activity would show up not long after you received the cabinets if they came infested. Now, if it's powder post beetles they could have been in the raw wood without you or even the cabinet company knowing they were there. Powder post beetle larvae can stay dormant up to 20 years sometimes in the wood and then emerge. If that is what you have, your best mode of action would be to have your home tented/fumigated to kill them all at once. Termidor Foam won't work for you in that case and the products we have that would work would require you sand your custom cabinets down to raw wood and then apply them. This is a tough situation for you but fumigation is almost your only option.

QTermidor Foam vs Termidor SC?
What is the advantage of the foam vs the liquid termidor? Wouldn't spraying liquid termidor into a wall void at the top of the wall be essentially the same? If not better? Liquid termidor has a 6 month residual. Foam supposedly is good for only a few weeks. If you insert a spray nozzle into your wall and pull the trigger, all that liquid will saturate the wall and drip down covering the studs, insulation, drywall, whatever.... In fact I would think that liquid would be able to penetrate cracks and crevices better than any expanding foam.... So the drywall gets wet, big deal it will dry ... What say you?

ATermidor Foam is the preferred option over Termidor SC when treating an active infestation of termites behind a wall. When performing a spot treatment behind a wall it is very important to drill directly into the affected stud and foam into the termite galleries as well as the void on either side of the stud. You will not foam the entire void with Termidor Foam, rather you will drill a hole close to the top of the ceiling/stud on either side of the stud. Once the holes are in place on each side, inject the foam into each hole for 5-10 seconds, allowing the foam to expand but slide down the sides of the studs where they would travel. Foam is preferred because it has the ability to expand and travel deep into the termite galleries, cracks and crevices, and wall void much better, which does provide better coverage than liquids.

Termidor FOAM  and Termidor SC when accompanied by a foaming agent would be the same application. However, the Termidor SC with a foamin agent would cover more area, and certainly be more economical if you had larger areas or more than one area to treat.

QCan I rub Termidor Foam on antique furniture? Will it harm cats or myself?
I am moving antique furniture, but want to be rid of termites. I also have many cats. What are the dangers? I have read Termidor is for outside use.


No, Termidor SC should only be used indoors if you are treating an active termite infestation and you know where the pests are. We would not recommend applying this product while pets and/or children are indoors. Once the product has dried completely, it is safe for pets to return to the area.

QWhat if I'm only treating part of a termite infestation with Termidor Foam?
I know there are termites in one area of a wall. I can't see where else they are, but no doubt they are also in other cavities. If I treat with foam in one area, but miss a bunch of other areas that they are in, am I going to disrupt the group and make them move to a new spot...something I DON'T want to do. I am doing the ground treatment, but I'm suspicious that they may have a satellite nest in a damp area of wall. Renovation of that wall will not start for 6-8 weeks and I'd like to treat before opening it up. I don't want them moving house to a new spot if I disrupt them with foam but don't foam most of them. Thoughts?


Termidor Foam, just like the liquid Termidor SC, is a non repellent formulation. This means that when spot treating in voids where you believe there is activity, the termites will not detect the product and it will not cause them to move. If you are doing a soil treatment as well this will take care of the colony as well and will transfer to the ones within the home.
