Drywood Termites & Its Treatment in Singapore

Drywood termites can vary in size from approximately 1/4 inch to a full inch, depending on their age and caste within the colony. Here are some key features to help identify them:

• Size: Drywood termites typically range in size from 1/4 inch to 1 inch. The size can vary based on their developmental stage and whether they are workers, soldiers, or swarmers (reproductive adults).
• Body Shape: Older drywood termites have an oval-shaped torso, which is relatively smooth and compact. Their bodies are somewhat flattened from top to bottom.
• Color: Their color can range from cream-white to light brown. The exact color can vary depending on their age and the specific species.
• Legs and Antennae: Drywood termites have six distinct legs that are relatively short and robust. Their antennae are straight and are approximately the same length as their head.
• Wings (for swarmers): Swarmers, or reproductive adults, have two pairs of wings that are equal in size and extend beyond the body. The wings are often transparent with a slight yellowish tint.

Discarded Wings: Flying drywood termites, also known as swarmers or reproductive adults, shed their wings after mating. You may find these wings near windowsills, light fixtures, or other areas where swarmers exit the building.

Wood Damage: Small holes in wooden surfaces and frass (termite droppings) that resemble tiny pellets or sawdust are common signs.

Sawdust Piles: The fine, powdery frass is often found near the infested wood.

Hollow Sound: Tapping on infested wood may produce a hollow sound.

HDB Homes: Drywood termites can infest wooden components such as door frames and furniture. The risk is lower compared to landed properties but still present if wooden materials are used.

Condos: In condominiums, drywood termites can affect wooden beams, trim, or furnishings. Regular inspections are advisable.

Landed Properties: Landed homes with wooden elements, including decks and furniture, are more susceptible. Due to the large amount of accessible wood, infestations can spread quickly.

Commercial Buildings: Commercial properties with wooden interiors or furnishings can also be affected. Regular pest control measures are crucial to prevent damage.

Moisture: While drywood termites prefer dry wood, excess moisture from leaks or high humidity can attract them.

Wood Contact: Infested wood can spread termites to other wooden structures through contact.

Wood Storage: Storing untreated or unfinished wood near a building can attract drywood termites.

Structural Damage: Extensive damage can occur as termites hollow out wooden components, potentially compromising structural integrity.

Furniture Damage: Wooden furniture and fixtures may suffer damage, impacting their usability and appearance.

Cosmetic Damage: Infested wood often shows visible damage and frass, affecting the aesthetic value of the property.

Professional Assessment: Professionals use tools for thorough inspections to detect hidden infestations.

DIY Inspection: Regular checks for damage, frass, and discarded wings are recommended. Look for unusual sounds or hollow spots.

Foaming is the most effective and commonly used treatment method to exterminate drywood termites in Singapore. It ensures that the termiticide reaches the termites directly and provides lasting protection against reinfestation.

The treatment area is prepared by identifying and accessing the infested wood. This may involve drilling small holes into the wood where termites are active. A termiticide is injected into these holes. The foam expands to fill voids within the wood, reaching areas that are otherwise difficult to access. The entire foaming process typically takes about 1 to 2 hours, depending on the size and extent of the infestation. The treatment’s required amount of drilling and effectiveness depends on the infestation’s nature and the chemical used. Most termiticides used in foaming treatments remain active in the wood after application, preventing reinfestation by exterminating any remaining termites.

Reduce Moisture: Fix leaks and manage humidity levels to deter termites.

Regular Inspections: Schedule regular pest inspections to catch infestations early.

Wood Treatment: Treat wood with termiticides and maintain it properly.

Seal Entry Points: Ensure wooden components are sealed and check for gaps or cracks.
