Termidor FOAM - Questions & Answers

Yes, as long as you were able to rinse the area Termidor foam touched with soap and water for 15 minutes, there should be no harm. If you are still concerned please contact BASF 800-526-1072.

The Alpine Ant and Termite Foam would be a fantastic option to perform spot treatments and it is for sale to California residents. Alpine Ant and Termite Foam comes from a new line of Reduced Risk Non-Repellent products which means effective pest control with a safer active ingredient. 

If you have drilled into the soil and are treating the soil under the slab then it is best to use Termidor SC. When you use Termidor SC in soil, it will last atleast 10 years.

To treat wood studs, you want to drill a 3/8 to 1/2  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. It 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. If you know where an active infestation is, you should indeed direct treat with the Termidor Foam. The foam will only last for about 6 weeks because it is not bonding with soil molecules. An outside trench will need to be performed also. Please click on the article on how to perform your own termite treatment for additional information and tips.

Termidor 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. 

You can kill the termites yourself! The easiest and most efficient way would be to use Termidor Foam.

Termidor SC should be applied in a 6" by 6" trench directly around the exterior of the structure. It is not applied indoors. It is labeled for outdoor use only. Termidor Foam can be used indoors for a spot treatment that will kill existing termites but will only provide up to 6 weeks of treatment and does not replace the exterior trench treatment. Please contact us at 866.581.7378 for more information on treating for termites.

You can use the Termidor Foam by injecting it into the baseboard and applying behind the baseboard. You should not just apply to the exterior of the baseboard as the foam will not soak into the wood and the termites would go untreated.

Termidor Foam should be applied into approximately a 1/8" - 1/4" hole dispersed through the black tip on the injection tube of the can. Please let us know if you need anything else. 866.581.7378

You mentioned finding sawdust but you did not mention finding mud tunnels. Do you know if you have subterannean termites or drywood termites?

You can treat this infestation yourself using a product such as Termidor Foam. You will need to drill into the infested area and apply the foam. 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.

If you know where an active infestation is, you should indeed direct treat with the Termidor Foam. The foam will only last for about 6 weeks because it is not bonding with soil molecules. This bonding makes the active ingredient last for many years vs several weeks. Premise does only give you about 5 years of coverage.

You want to inject the Termidor foam into the studs. You also want to perfom a perimeter trenching around the stucture and apply a termiticide like Termidor SC. Please review our article Do It Yourself Termite Control.

Termidor Foam will treat for carpenter ants if injected directly where they are infesting as directed on the product label. However, since you are treating a live tree we recommend using Maxforce Carpenter Ant Bait Gel. We have had lots of customers use this product in live trees with carpenter ants and have had much success.

Yes, the Termidor Foam comes with all parts (including actuator) required to operate and foam into any void where there is an active infestation. No other parts are required to be purchased in order to utilize this product.

You will need to determine what kind of termite you have for us to direct you on the best treatment method. If you have drywood termites, you could drill holes into the galleries and inject a product like Termidor Foam to expand and eliminate the colony. You will only be injecting the foam into the studs and around where the activity is, not filling the entire wall void. It would be hard to determine exactly how many cans you would need withouth knowing where you are primarily seeing activity. If you have subterranean termites, you will need to do a trench treatment around the home to eliminate the colony in the ground with a product like Termidor SC. Termidor SC will last in the soil for at least 10 years to both eliminate your current termites and prevent any new ones from entering the home. The Termidor SC trench treatment would kill the existing termites in the wall of your home as well, but you could always do a spot treatment with the Termidor Foam to help speed up the process along with the trench treament. You can see how a homeowner can treat there home for subterranean termites in our article "How To Do A Termite Treatment". There are many variables that go into treating your home for termites so it may be easier to call our customer service staff at 1-866-581-7378 for better instruction to meet the needs of you and your home.

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.

You can directly treat the nests by drilling into the posts and applying a product such as Termidor Foam. Where in your home are these posts located?
