Termite Signs in Furniture: Essential Checks Before Costly Damage
By Pest Tech TeamPublished 6 min readTermites

Termites rarely announce themselves. They eat wood from the inside, leaving a thin outer shell that looks normal until someone leans on a door frame or moves a wardrobe and it gives way. Learning the termite signs in furniture and doors means you can catch the problem while repair is still simple. This guide explains what to look for, how drywood and subterranean termites differ, and what to do next.
Termite signs in furniture and doors: the checklist
Walk through your home with a torch and the handle of a screwdriver. Check every door frame, wardrobe, kitchen cabinet and wooden piece that touches a wall or floor.
1. Mud tubes
Subterranean termites build pencil-width tunnels of soil to travel from the ground to their food while staying protected from light and dry air. Look for them:
- Running up walls to door frames and skirting.
- On the back of wardrobes and cabinets against walls.
- Inside cupboards, along corners and hinges.
- Coming out of cracks in the floor near furniture legs.
Break a small section. If it is rebuilt within a few days, termites are active.
2. Hollow sound
Tap wood firmly with the screwdriver handle. Sound, solid wood gives a sharp knock; wood eaten from inside sounds dull and hollow, and may crack or dent easily. Pay attention to the bottom 30 cm of door frames, which touch the floor.
3. Soft, crumbling or damaged wood
Press gently with the tip of the screwdriver. If it sinks in easily, or the surface breaks to show galleries packed with soil, termites have been feeding.
4. Blistered or bubbling paint
Termites working just beneath a painted surface can cause paint to bubble or blister, looking like water damage. If there is no leak behind the surface, suspect termites.
5. Frass (droppings)
Drywood termites push out tiny, hard pellets — like grains of sand or poppy seeds — from small holes. Small piles of these pellets under furniture or on window sills are a sign of drywood termites living inside the wood.
6. Wings
Piles of shed wings near windows, lights or doors, especially in May to July, mean a swarm has happened nearby. Our note on termite swarming season explains what that means.
7. Stiff doors and drawers
Termite damage and the moisture they bring can make wood warp, so doors and drawers stick or no longer close properly.
Drywood vs subterranean termites
Karachi homes mostly deal with subterranean termites, but drywood termites also attack furniture and frames. The signs and treatment differ:
| Subterranean termites | Drywood termites | |
|---|---|---|
| Where they live | Soil, entering the building from below | Inside dry wood itself |
| Key sign | Mud tubes; soil packed in galleries | Small piles of hard pellets (frass) |
| What they attack | Door frames, skirting, cabinets, anything touching walls or floors | Furniture, window frames, wooden ceilings |
| Colony size | Very large | Smaller, but can be several in one piece |
| Treatment | Soil barrier (drill-fill-seal) plus woodwork treatment | Direct wood treatment, injection, or replacing the piece |
Fine powder with round holes is a different pest altogether — wood borer (ghun). Our wood borer treatment page explains how that is treated.

Where to check first in a Karachi home
| Location | Why termites choose it |
|---|---|
| Kitchen cabinets under the sink | Moisture from pipes, wood touching the floor |
| Main door and bathroom door frames | Frame sits on the floor; bathrooms are damp |
| Built-in wardrobes | Large wooden surface against a wall, rarely moved |
| Skirting boards and wooden flooring | Direct contact with walls and floor |
| Bookshelves and stored files | Cellulose food, rarely disturbed |
| Store rooms and servant quarters | Cardboard, old furniture, damp |
| Window frames | Especially where rainwater leaks in |
Homes near the sea, such as in DHA Karachi, and older houses with lots of built-in woodwork see termite damage most often.
What to do if you find signs
- Don't spray the wood with market insecticide. It kills a few workers and may drive the rest to another part of the house.
- Don't remove or replace the wood yet. New wood placed against an active colony will be eaten too.
- Take photos of mud tubes, damaged wood, frass and any wings.
- Note where you found them — every room and piece of furniture.
- Book an inspection. A technician will identify the termite type, trace the entry points and recommend treatment.
How termite damage in furniture is treated
- Subterranean termites are treated at the source with a soil barrier: drilling along wall-floor joints, injecting termiticide, and sealing. Infested woodwork is injected or surface-treated at the same time. Our termite control service explains the method, and our guide to termite treatment cost in Karachi explains how quotes are built.
- Drywood termites are treated by injecting the affected wood directly, or by replacing badly damaged pieces.
- Loose furniture that can be moved may be treated separately or, for small drywood infestations, left in strong sun as part of treatment.

Can the furniture be saved?
Often, yes. If the damage is limited to the surface or the bottom of a frame, the wood can be treated and repaired once termite activity has stopped. Heavily hollowed pieces — especially structural door frames — may need replacement, but that should wait until treatment has worked so the new wood is not attacked.
Checking furniture before you buy or move
Second-hand furniture, antiques and furniture from storage can bring termites and wood borer into a clean home. Before it comes inside:
- Turn it over and check the unfinished underside and back panels.
- Look for fresh frass, fine powder, mud or soil in joints.
- Tap the legs and frame for hollow sounds.
- Open drawers and check the corners and runners.
- If in doubt, keep it outside or in a separate room until it has been checked or treated.
When moving house, check your own furniture the same way before it goes into the new home.
Preventing future damage
- Keep wooden furniture a few centimetres away from walls.
- Fix leaks under sinks and in bathrooms promptly.
- Avoid storing cardboard and paper against walls.
- Check second-hand furniture for frass and holes before bringing it home.
- Book an annual termite inspection before the pre-monsoon swarming season.

Frequently asked questions
Can furniture with termites be saved?
Often yes, if the damage is limited. Treat the termites first, then repair or reinforce the wood once activity has stopped. Badly hollowed pieces may need replacing.
Should I spray termite-damaged furniture myself?
No. Market sprays kill a few termites on the surface and can push the colony elsewhere. The colony must be treated at its source.
Should I replace damaged door frames immediately?
Wait until treatment has worked. New wood placed against an active colony will simply be eaten too.
How do I tell termites from wood borer in furniture?
Termites leave mud tubes and soil-packed galleries (subterranean) or hard pellets (drywood). Wood borer leaves neat round holes with fine, flour-like powder.
