Drywood Termite

Drywood termites are a type of termite that live and feed on dry wood, as opposed to subterranean termites, which live and feed on damp wood. They typically infest the structural wood of buildings, such as the framing, flooring, and furniture. Drywood termites are usually found in warm coastal regions and are less common in colder climates. These termites do not require contact with the soil, and they can establish colonies in any piece of wood with a moisture content of less than 20%. They typically enter structures through small cracks or holes in the wood and can cause significant damage if left untreated.

Drywood Termites Behaviour

Drywood termites are a type of termite that infest dry wood and do not require contact with the soil. A single colony can spread over several meters and occupy multiple locations within a structure. They obtain all the moisture they need from the wood consumed or through their metabolism, meaning they do not require an above ground source. These termites consume spring and summer wood, leaving behind clean and smooth galleries. They often enter homes through unscreened vents, cracks in the building exterior or around window and door frames, soffits, fascia boards, and roof seating. To retain moisture, their cuticle is more water-resistant than that of subterranean termites.

Drywood termites are considered pests because they can cause significant damage to the structural wood of buildings, such as the framing, flooring, and furniture. They can establish colonies in any piece of wood with a moisture content of less than 20%, and they can consume spring and summer wood. A single colony can spread over several meters and occupy multiple locations within a structure, making detecting and eliminating the infestation hard. The damage caused by drywood termites can weaken the structural integrity of a building, making it unsafe to live in. They can also cause aesthetic damage to furniture and other wooden items.

In addition, they can be costly to exterminate, and the control measures can be disruptive to the homeowners. Drywood termites also can be a nuisance as they can swarm in large numbers, which can be alarming for homeowners. Thus, for these reasons, drywood termites are considered pests, and it is vital to take steps to prevent and control infestations.

Several signs may indicate a drywood termite infestation:

1. Swarmers: During certain times of the year, adult drywood termites will swarm or fly out of the nest in search of new areas to colonize. These swarms can signify an infestation, primarily if the swarmers are found inside the home.
2. Frass: Drywood termites excrete a small, sawdust-like material called frass. This material can accumulate below the infestation and indicates drywood termites are present.
3. Damaged Wood: Drywood termites consume the wood from the inside out, leaving a thin layer of intact wood on the surface. This can cause the wood to sound hollow when tapped, resulting in minor or “kick-out” holes on the surface.
4. Wings: After swarming, drywood termites will shed their wings, which can be found near windowsills, door frames, and other areas where they may have entered the home.
5. Discolouration or Warping: As drywood termites consume the wood, it can become discoloured or start to warp. This is a sign that the infestation has been present for some time.

It’s important to note that one or more of these signs does not necessarily mean that drywood termites are present. It could be other pests or natural causes. Therefore, a professional pest control inspector should be consulted to confirm an infestation and identify termite species.
