Termite Foam Injection Treatment

Foam and PrecisionInjection treatments are excellent treatment solutions for drywood termite infestations. Both methods can be used to treat smaller infestations in localized treatment areas or used as a residual to protect your home or business from recurring drywood termite infestations. They also allow us to treat the infested area directly minimizing disruption to your home or business operations.

Foam Injection vs. Drilling vs. Tenting

Most termite problems can be solved more than one way. The right choice depends on how far the infestation has spread, how accessible the galleries are, and how much disruption you’re willing to accept. Here’s how foam injection compares to the two most common alternatives.

	Foam Injection	Drill & Treat	Tent Fumigation
Best for	Localized infestations in wall voids and hard-to-reach galleries	Accessible infested wood where the galleries can be reached directly	Widespread infestation across an entire structure
How it works	Expanding foam carries the treatment through the void and coats gallery surfaces the liquid alone wouldn’t reach	Small holes are drilled into infested members and treatment is injected directly	The structure is sealed under tarps and filled with fumigant gas
Leave your home?	No	No	Yes — typically three days
Cosmetic impact	Minimal — small entry points, patched after treatment	Visible drill holes requiring patch and touch-up	None to the wood, but roof tiles and landscaping can be damaged by tarping
Food & medication prep	None	None	Everything consumable must be bagged or removed
Main limitation	Treats the areas reached — not a whole-structure solution if the infestation is everywhere	Only works where the technician can physically access the wood	No residual protection — termites can return the day after the tent comes off

Foam injection sits in the middle: more thorough than drilling alone in enclosed spaces, far less disruptive than a tent. For most localized drywood activity, it resolves the problem without anyone leaving the house.

If the infestation turns out to be widespread, we’ll tell you that directly. See all of our alternatives to tenting .

Foam Spray

Foam sprays are low in toxicity, making them an excellent treatment option for drywood termites. They have large coverage capabilities and penetrate deep into the exposed wood they’re sprayed on. Protected wood also offer excellent residual protection against future infestations as they decompose slowly and remain in the wood for a long time. They are cost effective making them an excellent choice as a primary treatment or as a post-treatment layer of protection.

Precision Injection

Wood injection or “drill-and-treat” applications have been used since the 1920s to treat drywood termite infestations that are accessible and detectable. An insecticide is injected into small holes drilled through any wood surface into termite galleries delivering the treatment directly to the pest population. This is the simplest and most direct method of treatment. The amount of drilling required and the effectiveness of this treatment depends on the chemical used and the nature of the infestation. Most chemicals will remain active in the wood after treatment to thwart resurgent colonies.
