What method is NOT typically recommended for treating wood-destroying pests?

Granular bait is not typically recommended for the treatment of wood-destroying pests primarily because these pests are often located within the wood itself or in areas that are difficult to reach with granular products. Effective treatment for wood-destroying insects, such as termites, usually requires methods that can penetrate the infested materials or the surrounding soil to reach the pests directly.

Foam treatments, liquid sprays, and soil injections are more appropriate because they can be applied directly to the infested wooden structures or the soil surrounding them, ensuring that the pesticide can effectively target the pests. Foam treatments can expand in wood, allowing for deeper penetration, while liquid sprays adhere to surfaces, and soil injections create a chemical barrier against pests entering the structure from the ground. Granular baits, while useful for some pest control scenarios, lack the delivery system necessary to effectively address the specific challenges posed by wood-destroying insects.
