Protect your home from termites with pest control services

D-Foam residual is another excellent termite killing product manufactured by FMC Corporation—a renowned American chemical producer that also produces high-quality pest control products.

The active ingredient in this foam-based product is Deltamethrin, a synthetic version of an insecticide derived from chrysanthemum flowers. It is used in a variety of insecticides and works by disrupting the normal functioning of the insect nervous system.

Termites and other wood-destroying insects are instantly killed after they come into contact with this product. It has a high expansion ratio of 60:1, so it has the potential to get deep into wall voids, floor joists, damaged wooden structures, and many other areas.


Kills wood infesting insects – termites (drywood termites, subterranean termites, Formosan termites) and others

It has an expansion ratio of 60:1 and reaches the most bottomless voids of floor joists, damaged wooden structures, and many other areas.

It can produce approximately 10 gallons of finished termite foam.

Offers long-lasting residual effects and delivers effective termite control for up to 8 weeks.


It’s a bit expensive and might not be as powerful as other Termite Killing Foams like Termidor.

Tools Needed

There are no tools needed to use the D-Foam as it is ready to use, but you may need a drill to drill holes in the walls to inject foam in certain areas.

How to Use

Shake well before use. Hold your can upright and remove the cap. Direct the injector to cracks, crevices, void, or holes in walls, and press the button down. Inject a sufficient amount to allow for thorough coverage of all construction void surfaces being treated. If necessary, drill holes into walls, termite galleries, or voids for more comfortable injections. Distribute the drill holes to treat the infestation properly. Applications must be made for inaccessible structure voids by drilling and then injecting into the infested void. For the various type of termites, the purpose of such applications is to kill workers or winged forms that may be present in the treated areas at the time of application.

Where to Use

Use D-Foam Insecticide where you have ant or termite activity or other wood-depleting insects to remedy pest situations. Treatment can be done in cracks and cracks alongside windows and doors, wood structures, wall voids, crawl spaces, behind sheet rocks, termite exit holes, and other areas where insect infestations may occur. This can be applied indoors and outdoors for homes, restaurants, warehouses, hotels, hospitals, supermarkets, and other establishments.

When to Use

D-Foam Residual Foam should be used as part of a termite treatment program or when insects are hidden in voids that are difficult to penetrate with other termite insecticides.

Target Pests

D-Foam Residual targets a range of pests: Subterranean termites, Formosan termites, Drywood termites, Carpenter Ants, and Carpenter Bees; Ants, Bees, Carpet Beetles, Centipedes, Cockroaches, Crickets, Firebrats, Fleas, Gnats, Mole Crickets, Moths, Pillbugs, Silverfish, Spiders and other crawling insects

Safety Information

Care should be taken while using this product near humans and pets, just like other insecticides. It is also recommended that manufacturers keep children and pets away after using foam until it is dry. Remove pets, birds and cover fish aquariums before treatment. In schools and nurseries, do not apply this product when classrooms are in use nor when children are present. Do not apply this product in rooms while occupied by the elderly or infirm.

The product should also avoid contact with skin, eyes, or clothing and hands thoroughly washed with soap and water after handling and before eating or drinking. If it is on clothing, it is recommended that it be removed immediately and that the skin be rinsed with plenty of water.

Special Considerations

D-Foam comes in a 14 ounce can with a plastic straw applicator attachment to make it easier to reach voids and galleries, unlike spray and liquid insecticides. With an expansion rate doubled from other existing brands, this product is best suited to large and spread termite infestations. In addition, this product has a long-lasting residual effect that will continue to deliver effective control for up to 8 weeks. It can produce approximately 10 gallons of finished termite foam.


How safe is Deltamethrin?

When used according to label directions, Deltamethrin is safe to use and can be applied according to label directions.

How long does the effect of D-Foam residual lasts?

With up to eight weeks of residual control, D-Foam protects against harmful pests such as ants, wasps, cockroaches, silverfish, fruit flies, and other wood-eating pests.

Can D-foam eliminate a termite colony?

D-Foam has the active ingredient Deltamethrin, which offers a fast knockdown and a long-lasting residual. D-Foam does not, however, spread back to the nests. It will only eliminate termites that come into direct contact with treated areas.


The D-Foam Residual Foam with Deltamethrin is another excellent option for termite foam. Containing 0.06 percent concentration of Deltamethrin as an active ingredient, it can be used as a spot treatment for termites and other wood-destroying pests. You can use it in both domestic and commercial, indoors and outdoors. Its formulation is, in fact, safer for indoor use; the death rate against termites may suffer due to the low toxicity compared to other chemical ingredients. It’s a little bit expensive, though, and it’s not as powerful as the top termite-killing products in the market, such as Termidor, termite baits, and liquid termiticides. However, it’s still one of the excellent termite killing foams for such an elusive pest, highly recommended.
