Woodworm treatment in Hoofddorp: diagnose first, then treat
What we call woodworm is the larva of the common furniture beetle. It lives hidden inside the timber for years, gnawing a network of tunnels. Only when the adult beetle emerges does the familiar round flight hole appear. Holes therefore show that beetles have flown out at some point, not necessarily that larvae are still inside.
So at the inspection we first assess whether the attack is active, which species is involved, how far the damage extends and whether damp plays a part. If treatment is needed, we apply a professional product onto and into the affected timber so that it reaches the larvae in their tunnels. Loose pieces of furniture are treated separately, and sound wood around the problem is left alone.
Signs of an active attack
Whether there is still life in the wood shows in a combination of signs:
- fresh, pale bore dust beneath the holes, fine as powder, which reappears after you sweep it away
- holes with sharp, light-coloured edges rather than dark, weathered ones
- small brown beetles in spring or summer, often near a window
- wood that feels soft or crumbles when you press a screwdriver into it
Larger oval holes in softwood, in the roof timbers for example, may point to the house longhorn beetle. It mainly attacks structural timber and needs extra attention.
Where woodworm feels at home
Woodworm likes timber that is slightly damp and unheated. Joists in a crawl space, lofts, barns and old farmhouses are therefore more vulnerable than a heated living room. Sapwood, the lighter outer layer of the trunk, is particularly popular, and old plywood and untreated furniture are attacked too.
Woodworm often enters a home in a second-hand or antique piece of furniture, or in old timber reused during a renovation. From there, emerging beetles can lay their eggs in other suitable wood nearby.
What you can do yourself
You can prevent a lot, and check a fair amount yourself:
- Inspect second-hand furniture for holes with fresh dust before buying, and do not bring a doubtful piece straight indoors.
- Sweep away the dust under suspicious holes and look again a few weeks later; fresh dust is a strong sign of activity.
- Keep the crawl space and loft dry and well ventilated.
DIY products rarely penetrate thick beams deeply enough. For floors, joists and the roof structure, a professional woodworm treatment is the safer choice.
Woodworm or something else?
Not every hole or pile of sawdust means woodworm. Gnaw marks with splinters and droppings on beams in the crawl space point more towards rodents; read about mouse control. Grey scratches on garden furniture or a fence are often the work of wasps scraping off wood fibre for their nest; see wasp nest removal for more.
If in doubt, have it assessed before you throw anything out or start treating it yourself. For all other pests, our pest control in Hoofddorp service can help.
