What type of solution is commonly used to treat the inside walls of a home for termites?

The use of a foam solution for treating the inside walls of a home for termites is effective due to its ability to expand and fill various voids and cracks within the structure. Foam solutions are particularly beneficial in areas that may be difficult to reach with traditional liquid pesticides, allowing for more comprehensive coverage. The formulation adheres well to surfaces and can penetrate into hidden spaces where termites may be nesting or traveling, which is crucial for effective treatment.

While liquid pesticides and spray solutions are also utilized in termite treatment, they may not offer the same level of penetration into hard-to-reach areas as foam. Granular bait is generally used in a baiting system outside the home rather than treating inside walls. Therefore, the properties of foam solutions make them a preferred method for addressing termite infestations specifically within the interior structure of a home.
