However termites can build their shield tubes over chemically treated timber and infest stained timber over, if susceptible wood is used above the treated timber. .

Use just pressure-treated lumber for areas which are exposed to weather; otherwise, the chemical in the timber may leach from the wood. All remedies which will be exposed to weather must have a sealer coat to avoid leaching into the soil following rain.

Not known Facts About Termite Control Products

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

To ease control of hop over to these guys subterranean termites, destroy their shelter tubes possible to interrupt access to wooden substructures. .

Subterranean termite baits, that are insecticides shared inside the colony and consumed during feeding, are available in California. Normally, bait is delivered within a wood or cellulose matrix installed around a construction and infused with an active ingredient. Industrial bait products are available for usage, where there is not any dirt for station setup.
