7 Early Signs of Termite Infestation in Delhi Homes

Published by RDP Technical Team • Sector 7, Dwarka

Subterranean termites cause billions of rupees in structural property damage each year across Delhi NCR. Because they consume wood from the interior outward, colonies often go unnoticed until structural integrity is compromised.

1. Mud Shelter Tubes on Walls

Subterranean termites require constant moisture to survive. They build pencil-thick brown mud tunnels across concrete walls, brick joints, and tile skirtings to travel safely between their soil nests and wooden fixtures.

2. Hollow or Papery Sounding Wood

When you gently tap door frames, baseboards, or built-in wardrobes with the handle of a screwdriver, infested wood produces a distinct hollow or dull papery sound.

3. Tight-Fitting Doors and Sticking Windows

As termites feed inside wooden jambs and moisture from their activity builds up, the wood warps and expands, making doors and wardrobe panels difficult to open or close smoothly.

4. Discarded Swarmer Wings

During humid monsoon evenings in Delhi, reproductive winged termites (alates) emerge in swarms to establish new colonies. Shortly after flight, they shed their delicate translucent wings, leaving piles on window sills and floor corners.

5. Bubbling or Peeling Paint

When termites consume drywall paper backing or the wood underneath painted surface veneers, the paint layer begins to bubble, blister, or show faint brown pinholes.

6. Fine Wood Dust (Frass)

While drywood termites produce distinct tiny pellets, subterranean termites leave fine powdery soil and wood debris pushed out of small kick-out holes in skirting boards.

7. Quiet Clicking Sounds at Night

When soldier termites detect disturbance in wooden cavities, they bang their heads against gallery walls to signal the colony, producing a faint rhythmic clicking sound audible in quiet rooms.
