Termites 101 - Prevention

A good way to deter termites is to grow plants that attract their predators. Termites’ natural predators include ladybugs, praying mantises, centipedes, and spiders. Planting catnip, geraniums, daisies, flowering herbs, or sunflowers will attract these insects.

Suppose you are building a new home or adding to an existing structure. In that case, there are several measures you can take to help prevent a termite invasion.

• Resinous woods are naturally resistant to termites.
• Purchase wood that is injected with chemicals or treated with borax.
• Make sure that all windows have tight-fitting screens.
• Test all doors and windows to ensure the frames are completely sealed.
• Eliminate any wood-to-ground contact.
• Prevent standing water near your home.
• Store firewood at least 20 feet away and elevated.
• Properly ventilate crawl spaces.
• Install termite barriers.

There are many types of termite barriers you may choose from.

Particle barriers, such as sand and basalt, are best used in climates where the underlying soil does not readily expand with moisture. Sand collapses when the termites attempt to burrow into it, and larger grains are too heavy for them to move.

Basaltic termite barriers, most commonly used in Hawaii, use basalt, a volcanic rock. The particles are too heavy for termites to move while also leaving spaces too small for them to squeeze through.

Plastic termite barriers use plastic sheeting treated with an insect repellent or insecticide. They are installed underneath the foundation slab during construction.

Chemical barriers use a residual treatment on the soil before pouring your foundation slabs. Pre-treating the soil around the perimeter of your home will help provide an early defense against termites and other insects.

Termite shields consist of durable metal sheeting carefully assembled to provide no holes or cracks through which a termite may enter.

Stainless steel mesh barriers are another method, but they may not be readily available. These barriers use a non-toxic steel mesh that termites cannot chew or squeeze their way through.

It should be noted that barriers work best when part of a deterrent system and not on their own.
