Short Answer
Anti-termite treatment on plywood is a chemical, not a property — it wears off in one to two years, the cut edges inside the carcass are never treated, and re-treatment means emptying the wardrobe. A structurally termite-proof board like WAZWOOD Board has a polymer-bonded core with nothing for termites to eat (tested per ASTM D3345), so there is no treatment to reapply, ever.
Every year I get calls that start the same way: "we did anti-termite treatment, and there are still termites in the wardrobe." Here is why that keeps happening, and the one change that actually ends it. WAZWOOD Board — Designed For Legacy.
Why anti-termite treatment fails
Treatment is a coating or a dip. It sits on the surface of the plywood, or soaks a little way in. It is not part of the wood. So three things happen:
- It breaks down. The chemical degrades with time, heat and humidity. One to two years and its bite is mostly gone.
- The cut edges were never treated. When the carpenter cuts a treated sheet to size, every fresh edge inside the cabinet is bare untreated core. That is the way in.
- The board still softens. Ground-floor and basement units take rising damp through the slab. A damp, softening plywood edge is exactly what a termite colony is looking for.
The damage almost always starts at the back panel and the bottom shelf — the parts nobody sees until the door stops closing. By then the colony is established and a spray will not clear it.
What "termite-proof by structure" means
Termites eat cellulose. An engineered natural fibre composite board is plant fibre locked in a polymer binder — there is no free cellulose for an insect to digest, and no soft grain to tunnel along. WAZWOOD Board is tested to ASTM D3345, the standard laboratory termite-resistance test, and the core is structurally unattractive to termites and borers.
That is a different kind of protection. It does not wear off because there is nothing to wear off. A cut edge is the same material as the face — still nothing to eat. There is no annual pest-control line for the furniture, and no retreatment disruption in year three.
Treatment vs board — side by side
| Anti-termite treatment on plywood | Structurally termite-proof board | |
|---|---|---|
| How it protects | Surface / dip chemical | Material has nothing to eat |
| Lasts | 1–2 years | Life of the furniture |
| Cut edges | Untreated — the way in | Same protection as the face |
| Re-application | Empty the unit, spray, repeat | None |
| Annual pest-control cost | Recurring | Zero for the furniture |
| Standard tested to | Varies by applicator | ASTM D3345 |
Where it matters most
- Ground-floor and basement wardrobes — in the termite path, with rising damp. See wardrobe applications.
- Kitchen carcass and toe kick — damp plus food traces; see the kitchen material guide.
- Older buildings and re-soiled new construction — active colonies nearby.
- Gujarat and other high-termite states — pre-monsoon (March to May) is peak activity. See waterproof & termite-proof boards in Gujarat.
