Termidor FOAM - Questions & Answers

Termidor FOAM can be used to directly spot treat active nests in trees as directed on the product label. 

We would also suggest that you take a look at our Termite Guide for tips on how to treat and prevent an infestation in your home. 

Termidor FOAM can be used for a direct application to termite activity in wall voids, but has limited labeling for use outdoors.  If you have a subterranean termite infestation you would need to do a trench treatment around your home/structure with a termiticide such as Termidor SC.  You can refer to our Termite Treatment Guide for tips on how to do the treatment properly. 

Termidor FOAM can be used in localized areas to treat for active termites in flooring by using the holes already in the wood from termites or by drilling directly into the areas and injecting the foam. FUSE Foam contains both Imidacloprid and Fipronil so double treating the same areas with Termidor Foam would not be needed. 

BoraCare would be an alternative option for termites in wood flooring for both active termites and/or for preventative termite treatments. BoraCare absorbs completely throughout the wood and will last the entire life of wood however it can only be applied to raw untreated wood that is not painted,stained or sealed. Sufaces would need to be sanded down to the bare wood or injected into holes drilled into the wood. 

View our Drywood Termite Guide for more information. 

When using Taurus SC for the termite trench method, the application should have atleast 24 hrs to dry before any rainfall is expected.

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. It should not cause any staining if used as directed. 

 

Yes, you can treat this infestation using Termidor Foam. You will need to drill into the infested area to 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. For more tips, we recommend to read over step 1 of our article on How to Get Rid of Subterranean Termites.

Termidor FOAM should be applied into the drilled holes. You will not foam the entire wall 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. 

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. 

Termidor Foam will equal to 20 quarts of solution. 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. 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.
