How to Get Rid of Woodworm in the Furniture

Although more rare than cockroaches or rodents, woodworms are amongst the most destructive household pests.

Home owners, who have been unlucky enough to experience such infestation, know how hard it is to get rid of those pesky invaders and how the damage they do is often beyond any repair.

That’s why it is crucial to understand the common reasons why woodworms might infest your home.

What is a Woodworm

Woodworm is a collective term given to the wood boring larvae of several species of beetles, the most famous of which is the Death watch beetle.

What Causes Woodworm to Appear

As with almost all insect larvae, these “worms” thrive in warm, humid conditions and prefer the hospitality that rotten timber has to offer. Damp environments, caused by leaks or bad insulation, can quickly cause the wood to decay and it won’t be long before woodworms settle in.

Fungal problems, such as mould and mildew, only make matters worse as they weaken the structure of the wood and make it easier for the larvae to burrow deeper.

Another reason for the infestations is keeping untreated wooden material at your property. This includes not only driftwood and firewood, but also untreated furniture items, chattels, and even structural elements.

Signs of Woodworm in Furniture

The most obvious signs of a woodworm infestation in your wooden furniture include an often visible darkening of the colour, lots of holes in the wood, a cracking sound coming from the furniture and, to top it all off, you might find one or two adult beetles nearby.

What is the Difference Between Woodworm and Termites

Termites and woodworms both eat wood and are equally devastating, but making a difference between the two is the first step towards coming up with the appropriate solution.

The first difference stems from the fact that a woodworm is the larvae of specific types of beetles, while termites are a very social cockroach that live in colonies.

Unlike woodworms, termites do not bore visible holes in the wooden furniture, which is why it’s harder to detect them until there are more obvious signs.

How to Tell If a Woodworm Is Active

There exists the general misconception that once you see the holes in the wood, it means the woodworm has grown up and has left the nest.

And, in most cases, this is true. However, the same now grown-up beetle might come back and lay eggs in the place it once called home. As a result, your furniture will turn into a breeding ground for these insects.

What you should be looking for instead is an adult carcass, fresh ejected frass, and also checking the number and density of the holes.

How to Get Rid of Woodworm in the Furniture

Scan the damages. First, you need to be sure you’re dealing with a woodworm. Are there any holes? Do you hear the occasional cracking sound from your furniture? If yes, here’s what you should do next.
Determine whether the furniture can be saved. Most of the time, the woodworm would be eating the most upper layers of the wood furniture, while leaving the core and possibly even the surrounding areas untouched. This way, you’ll only need to treat the specific spot. However, if the structure seems weak, it might be better to simply throw it away.
Purchase a commercial woodworm treatment solution. The solutions you’ll find on the market come in large tubes and are highly concentrated. So, you’ll need to dilate them in water as you pour them in a spray bottle.
Wear protective gear. You’ll need to put on a gas mask, since you’ll be working with a toxic chemical.
Coat the surface of the damaged wood. Spray the solution over the damaged area. This will kill anything living inside.

How to Protect Furniture from Woodworm

Choosing a professional product is recommended for anyone who decides to treat this problem themselves. Sure, they are costly, but they are your best chance of treating the infestation.

But if anyone prefers to make their own product, here is what you should use for a…

DIY Woodworm Treatment

The first thing you must do is keep the room temperature dry as humidity attracts the beetles very easily.

Next, you need to melt beeswax and tint it into the colour of the wood, enough to fill in the holes. This method is sure to work as woodworms hate beeswax. However, it’s not a long term solution.

Alternatively, you may conceal the damage with ‘wood putty.’

Put sawdust into a cup and stir it together with wood glue until everything becomes a paste. Smear the mixture into the holes and immediately wipe away with a damp cloth. Let it dry out.

And, even if the woodworm is obviously gone, it would be a good idea to treat the rest of your wooden furniture with the same solution. The beetle might have simply left through the window, so pre-treat your remaining possessions just to be sure it doesn’t find itself a new nest.

Keep in mind that professional pest control exterminators know how to deal with woodworm infestations a lot faster and easier.
