Termite Control Methods: Safeguarding Your Woodwork and Home
Share
Woodwork, including doors, windows, cupboards, and finishes, plays a vital role in construction. However, it is susceptible to damage by termites, particularly white ants that feed on wood and other cellulose-based materials like textiles, paper, and cardboard. These pests can also harm non-cellulosic materials like plastic, leather, and rubber, making termite control a crucial aspect of protecting your home and belongings.
Types of Termites:
-
Ground-Nesting Termites (Subterranean Termites): These termites thrive in moist environments and are found across India. They maintain a connection to the soil, building tunnels to access buildings. They create secondary nests within wood and consume cellulose-based materials.
-
Drywood Termites: These termites prefer humid conditions and live directly in wood without soil contact.Primarily found in coastal South India, they live in smaller colonies.
Principles of Termite Proofing:
Effective termite proofing involves several key principles:
- Treat the building during construction.
- Ensure proper site drainage with impervious slabs below rainwater pipes.
- Provide flagging concrete around the building.
- Treat foundation gaps and plinth fillings with termite-proof chemicals.
- Seal floor joints with termite-resistant fillers or metal strips.
- Prevent gaps between the building and untreated soil.
Termite Proofing Materials:
While chemicals like Durmet (Chloropyrifos concentrate) and Dursban TC were once used, many are now banned due to health hazards. Recommended alternatives include emulsifiable chemicals like Heptachlor, Chlorpyrifos, and Chlordane concentrates, used in specific proportions.
Pre-Construction Termite Treatment:
Anti-termite treatment should begin when the foundation pits are ready. This creates a chemical barrier in the soil around the construction site, preventing subterranean termite entry. The process involves:
- Spraying termite hills found on the site with chemicals.
- Treating trench bottoms and sides up to 300mm with a chemical solution.
- Treating refilled earth around walls and columns.
- Drilling holes and treating them with a chemical solution after filling the earth up to the plinth level.
- Treating wall and floor junctions.
- Drilling holes along the external perimeter after construction and filling them with chemicals.
- Treating expansion joints and pipe/conduit perimeters.
- Coating wood in contact with masonry with protective paint.
Post-Construction Termite Treatment:
If termites are discovered after construction, post-construction treatment is necessary. Pressure pumps ensure chemical penetration. This process includes:
- Drilling holes in outer walls and filling them with chemicals.
- Treating soil under floors through drilled holes.
- Treating plinth-level walls by drilling angled holes and filling them with chemicals, then sealing them with cement mortar.
Structural Barriers:
For added protection, concrete or metal barriers can be installed. Concrete barriers, being more durable and corrosion-resistant, are preferable to metal ones. These barriers can be 50-75mm thick and extend beyond the plinth on both sides.
Professional Termite Control:
Termites pose a significant threat to your property. Engaging professional termite proofing services is essential to eliminate existing infestations and protect your home's wooden elements. These experts can assess the extent of the problem, apply appropriate treatments, and implement preventive measures to safeguard your investment.
By prioritizing termite prevention and control, you can ensure the longevity and structural integrity of your home,safeguarding your investment and preserving the beauty of your woodwork.
