Protecting your home from drywood termites

Commonly found in areas of California, Nevada, Arizona, Utah, and in the Southeast – from North Carolina through the Gulf Coast – drywood termites can go undetected for years, quietly chewing through one of your most valuable assets, your home.

Unlike subterranean termites, which make their nests in the ground, drywood termites live completely within the wood they infest, making early detection difficult. So, how can you tell if you have drywood termites?

It starts with how these silent destroyers operate. Understanding the biology of these insects and what drives them to infest a source, in this case the wood used to build your home, will help with early detection and prevention. If you’re worried about termites or have an immediate need for termite control, please don’t wait. Contact Western Exterminator today to schedule a free termite inspection.

Drywood termite behavior and how it differs

Subterranean termite species are dependent on a moisture source, such as the water contained in soil. They’ll make their way to your home by creating tunnels underground and continuing the journey above ground by means of mud tunnels. Mud tunnels may run along the foundation or walls of your home and are a visible sign of termite activity. Drywood termites will not give us this visible hint, as they will extract all the moisture they need from the wood they digest. Visible signs are often not as apparent until noticeable damage has already occurred.  

Drywood termites will chew through wooden support beams, floors, and walls. Because they have no preference for hard or softwood, they build wider galleries that usually compromise the structure of the wood more than those of subterranean termites, even with larger colonies. This means that a subterranean termite gallery will leave the hardwood quite sound, so the whole wood structure is less compromised, compared to a drywood termite gallery that will destroy the wood entirely until it collapses. And, because they live solely within a wood source, colonies can grow for years undetected, causing a significant amount of structural damage to homes. 

WARNING! Termites can also be transported to new locations if the wood is already infested. Furniture, picture frames, and building materials may harbor active termite colonies.

Signs of drywood termites

Drywood termites often swarm after it rains and a rise in temperature occurs. A termite swarm indicates a new colony looking to establish residency nearby. You may spot swarms indoors or outdoors. When seen indoors or near the house structure, you may think they came from outside. However, termites are weak fliers, and more often than not, the source will be inside the structure or very close to it.

Homeowners will often notice small piles of droppings or wings attached to spider webs or in the corners of the area. They may even notice the wood sounding hollow if they probe it. Sometimes it can also be easily broken or perforated.

Wings and droppings are the most common noticeable signs of drywood termites. However, as they live inside the wood, they could be inside your walls or attic without any external signs until the damage is so great that it becomes visible. Although frass-like droppings indicate activity, signs don’t always need to be visible for an infestation to be present. Drywood termites may refrain from expelling frass for a time. They may also expel it from a different hole that is not visible.

If you have seen any of these signs, don’t waste time. Ask for an inspection as soon as possible as the structure may have a drywood termite infestation.

7 drywood termite prevention tips

There are several things you can do to help prevent drywood termite activity and make your home less enticing to these wood-destroying insects. Here are 7 simple tips from our experts:

  1. Store firewood and scrap wood at least 20 feet away from your home.
  2. Seal all cracks and crevices around the home to prevent termites from gaining access to wood.
  3. Seal or paint any exposed wood that’s weathered or where paint is peeling.
  4. Routinely inspect your home for signs of termites: discarded wings, sawdust-like piles of droppings, and hollow-sounding wood. These are all signs of an infestation.
  5. Pay special attention to window and door frames, trim, eaves, siding, and in the attic.
  6. For any new construction projects, be sure to use treated wood.
  7. Remove any dead trees or stumps from your property.
