Woodworm treatment in Enschede: active or old?
Woodworm larvae live hidden inside timber for years, eating tunnels as they go. You only see anything once the adult beetle flies out. Watch for:
- round holes of 1 to 2 mm, often in clusters
- fine, gritty bore dust beneath the holes or in the gaps between floorboards
- wood that feels soft or crumbles when you press a screwdriver into it
- small brown beetles on the windowsill in late spring and summer
Pale bore dust and holes with sharp, fresh edges point to an active infestation. Holes that are dark inside and never have dust beneath them are usually old. That difference decides whether treatment makes sense.
Woodworm, longhorn or deathwatch beetle?
Most cases involve the common furniture beetle, the classic woodworm. It attacks furniture, floorboards, stairs and beams in both softwood and hardwood, mainly in the softer sapwood. It works slowly, and the damage often stays limited if you act in time.
The house longhorn beetle is more serious. Its larvae live in softwood such as roof timbers and leave larger, oval exit holes. Because they work unseen inside a beam for a long time, its strength can decline. In oak that is already damp or weakened by fungus, we occasionally find deathwatch beetle. The species determines the approach, and sometimes a carpenter or structural engineer needs to be involved too.
Our woodworm treatment, step by step
At the inspection we examine the affected timber closely, probe suspicious spots and measure the moisture content. We also look for the cause: a damp crawl space, a leaking gutter or a poorly ventilated loft. That way you get honest advice, even if it turns out the damage is old and nothing needs treating.
The same rule applies here as in all our pest control in Enschede: the cause first, the product second. If the infestation is active, we treat the wood with a professional product that only certified pest controllers may use and that penetrates deep into the tunnels. Paint or varnish sometimes has to come off locally first. Badly affected sections should be assessed and, if necessary, replaced by a tradesman. Loose furniture is treated separately.
Damp and ventilation: the basis of prevention
Woodworm thrives in timber with a high moisture content. Dry wood in a heated, well-ventilated house is far less appealing to the larvae. That is why most active infestations turn up where damp lingers: crawl spaces without proper ventilation, under a leaking roof, in unheated sheds and cellars, and in joists resting against a damp outer wall.
Keep air vents clear, have a wet crawl space dried out or insulated and repair leaks promptly. Do not stack firewood indoors or against a timber wall, and check second-hand or antique furniture carefully for holes and dust before bringing it inside.
Checking for live woodworm yourself
Want to know whether the infestation is active before you call? Cover the existing holes with masking tape or fill them with a little wax, and lay a sheet of black paper under the beam or piece of furniture. If new holes or fresh dust appear in spring and summer, there is still activity. Please do not sand or paint the wood before we have seen it, as that removes exactly the evidence we need.
If you also find droppings or gnaw marks next to the bore dust in the loft or crawl space, rodents are probably active as well; our mouse control page explains more.
