Prevention

Protecting your home from wood-destroying organisms starts with keeping wood as dry and well-sealed as possible. Moisture creates the ideal environment for termites, dryrot, and other pests to thrive. Here are some essential tips to safeguard your property:

• Repair Leaks Promptly: Whether it's a plumbing issue or a roof leak, addressing water intrusions quickly prevents moisture buildup and potential damage.
• Ensure Proper Drainage: Water should always be directed away from your home. Check that gutters and downspouts are clear of debris like leaves to allow rainwater to flow freely.
• Mind Soil Levels Around Your Home: Avoid piling soil too high against walls framed with wood. Water often gets behind stucco or siding and must be able to drain properly. Your weep screed—the gap that allows water to escape—should sit at least 4 inches above soil or 2 inches above concrete.

• Be Cautious with Plants Next to the House: Planter beds should not be higher than the wood framing in your walls. Elevated soil can trap moisture and compromise the protective barriers designed to keep your walls dry.
• Maintain Exterior Wood: Regularly inspect and repaint or reseal wood surfaces on your home’s exterior to create a strong barrier against moisture and wood-destroying pests.

Preventing Drywood Termite Infestations in Attics

Taking steps to prevent drywood termites during construction or in existing homes can save homeowners from costly repairs down the road. Here’s what you should know:

Pre-Construction Prevention

When building a new home, the framing stage offers a unique opportunity to apply long-lasting treatments directly to the surfaces of the wood. These preventative measures can protect the structure for the lifetime of the house. However, once the walls are sealed and wood surfaces are painted, access for treatment becomes limited.

Attics: A Vulnerable Area

In Southern California, attics often provide ideal conditions for drywood termites to thrive. Attic vents, in particular, are a common entry point. The screens on these vents are usually large enough for termites to pass through. To mitigate this risk:

• Install Interior Screens: Adding a standard window screen over attic vents from the inside can help block termite entry. Use caulking around the edges to ensure the screen is securely sealed. If your attic is designed to be vented, it’s important to maintain proper airflow to avoid moisture buildup and ensure effective ventilation.

Additional Protective Measures

• Pest Control Insulation: Loose pest control insulation can be blown into the attic. This can either replace the current insulation or be added on top of it to create an extra barrier against termites.
• Wood Treatment: Exposed wood in the attic can also be sprayed with preventative treatments to deter termite activity.

By taking these simple but effective measures, homeowners can significantly reduce the risk of drywood termite infestations in their attics and protect their investment for years to come.

Building with Pressure-Treated Wood

When constructing anything with wood that will be exposed to the elements, choosing the right materials and proper installation methods are key to ensuring durability and safety. Here’s what you need to know:

• Use Pressure-Treated Wood: For outdoor projects, pressure-treated wood is an excellent choice because it is treated with chemicals to resist decay, termites, and other pests. This makes it far more durable than untreated wood when exposed to moisture and the elements.
• Avoid Ground Contact: Even with pressure-treated wood, it’s best to ensure the material does not come into direct contact with the ground. Ground contact can accelerate decay and compromise the wood’s longevity.
• Safety Considerations: Pressure-treated wood contains chemicals that can leach out over time. If the wood is installed in areas where people may touch it, such as handrails or seating, it should be painted or sealed to minimize direct contact with the treated surface.
