Structural lumber in buildings is generally hemlock Douglas-fir, or spruce. Of these substances, Douglas-fir is moderately resistant to termites, whereas another two are not. Lumber used in bases and other wood in contact with the soil must be chemically treated or naturally resistant to termites and decay to help safeguard against damage in areas where building designs have to be altered or concrete cannot be used.

However termites may build their shield tubes chemically treated timber and infest untreated wood above if wood is used above the timber. .

Use only exterior-grade, pressure-treated lumber for areas that are exposed to weather; otherwise, the compound in the lumber may leach from the wood. All treatments that will be exposed to weather should additionally have a sealer coat to avoid leaching into the soil rain.

More About Termite Control Procedure

Subterranean termites in structures can't be controlled utilizing techniques that are acceptable for drywood termites, such as fumigation, heat treatment, freezing, and termite electrocution apparatus, since the reproductives and also a huge bulk of these termites are focused in nests near or below ground level out of reach of those control methods.

To facilitate control of subterranean termites, ruin their shield tubes whenever possible to disrupt entry to substructures. .

Termite baits, that can be insecticides shared within the colony and consumed during feeding, are available in California. Generally, lure is delivered within a timber or cellulose matrix installed underground in fixed intervals around a construction and also infused with the active ingredient.
