Wood Borer vs Termite: Expert Guide to the Right Treatment

Families often call us about "deemak" in their furniture, and when we arrive the damage turns out to be wood borer — ghun. Other times, what looks like a few holes from a beetle is actually a termite colony eating a door frame from inside. Getting wood borer vs termite right is the first step, because the treatments are completely different. This guide explains how to tell them apart, why the treatment changes, and how to protect furniture in Karachi's humid climate.

Ghun vs deemak: two very different pests

Wood borers (ghun) are beetles. The adult beetle lays eggs in cracks or pores in wood. The larvae hatch and tunnel through the wood for months or even years, feeding as they go. When they become adults, they chew their way out, leaving a small round exit hole and pushing out fine powder. Then they mate and lay eggs — often in the same piece of wood.

Termites (deemak) are social insects that live in colonies. Subterranean termites live in the soil and travel into buildings through mud tubes to feed. Drywood termites live inside the wood in smaller colonies. Either way, there is a colony that must be treated.

Wood borer vs termite: how to tell them apart

If you tap a leg of a chair and fine powder falls out of small round holes, it is almost certainly wood borer. If you find mud running up the wall to a door frame, it is termites.

A simple test at home

Place a sheet of dark paper under the furniture or frame where you have seen damage and leave it for a few days:

• Fine, pale powder collecting on the paper means wood borer larvae are active.
• Hard, sand-like pellets mean drywood termites.
• Nothing on the paper, but mud tubes nearby points to subterranean termites.
• Nothing at all may mean the damage is old and no longer active — but ask a technician to confirm.

Take a clear photo of what collects and send it to us; it makes identification easy.

How fast does the damage progress?

Wood borer damage builds slowly — larvae may feed for a long time before the first exit holes appear — so by the time you see holes, the infestation may be several generations old. Subterranean termites work much faster because a colony has thousands of workers feeding at once. Either way, active infestations only get worse with time.

Why the treatments differ

Termites

Because subterranean termites come from a colony in the soil, the colony must be targeted. The standard treatment is a soil barrier: drilling along walls and floors, injecting termiticide into the soil, and sealing, with separate treatment of infested woodwork. See our termite control service and our guide to termite signs in furniture.

Wood borer

Wood borer larvae live inside the wood, so treatment goes directly into it:

1. Inspection — finding every affected piece, including hidden sides of furniture.
2. Injection — a suitable insecticide injected into exit holes so it spreads through the tunnels.
3. Surface treatment — brushing or spraying unfinished surfaces so the product penetrates, and so new beetles cannot lay eggs.
4. Repeat check — new exit holes can appear for a while from larvae already deep inside; a follow-up confirms whether activity has stopped.
5. Sealing — once treatment is complete, filling holes and polishing or varnishing the surface.

Our wood borer treatment service covers furniture, doors, wooden ceilings and bamboo.

Is the same chemical used for both?

Some active ingredients can work on both pests, but the way they are applied is completely different — soil injection for subterranean termites, wood injection and surface treatment for wood borer. A company that suggests one quick spray for both is not treating either properly.

Why Karachi's humidity matters

Wood borer beetles are more active in warm, humid conditions, and damp wood is easier for larvae to tunnel through. In Karachi, furniture near the sea — in Clifton and DHA — and furniture stored in damp rooms are especially at risk. Termites also prefer damp conditions, which is why both pests are common in bathrooms, kitchens and store rooms.

Protecting furniture from both

• Seal and polish. Varnish, polish and paint close the pores where wood borer beetles lay eggs. Unfinished surfaces — the backs and undersides of furniture — are the most vulnerable.
• Keep wood dry. Fix leaks and avoid placing furniture against damp walls.
• Leave a gap between wardrobes and walls for air flow and inspection.
• Inspect before buying. Check second-hand furniture and antiques for fresh holes and powder before bringing them home.
• Isolate infested items — move them away from other furniture until treated.
• Choose treated timber for new furniture and fittings.
• Book an annual inspection for both pests, ideally before the monsoon.

Does furniture polish kill wood borer?

Polish and varnish help prevent new beetles laying eggs, but they do not kill larvae already inside the wood. Treat active infestations first, then polish.

Is there a season for wood borer?

Adult beetles tend to emerge in the warmer months, so fresh holes and powder often appear in spring and summer. Larvae keep feeding inside the wood all year. If you notice new powder, treat it without waiting for a particular season.

Estimate and book

Wood borer treatment is priced by the number and size of the pieces treated, so we quote after seeing photos or inspecting. For termite work, the termite treatment cost calculator gives a range by area.

The National Pesticide Information Center has a clear overview of termite identification and control that also explains why termites need colony-level treatment.
