How to Get Rid of Woodworms Naturally

What are woodworms?

The woodworm is a type of larva that feeds on wood. The term applies to wood-boring insects in their larval stage. These beetles can completely destroy your favourite wooden fitments if left unchecked. They can chew and burrow into chairs, tables, cupboards, floorboards and more, and almost nothing can stop them. Keep reading to find out how to get rid of woodworms.

So if you:

  1. Have noticed any signs of active woodworms, like fresh frass around furniture, holes and tunnels in timber, crumbling or wood;
  2. Want to save your antique or valuable wood furniture from destruction;
  3. Would like to sell your furniture and want to get rid of the woodworms.

What causes woodworms?

There are many reasons for woodworms to attack your household appliances and furniture, but here are the most likely causes of woodworm infestation:

  • Damp environments: this is the most common reason woodworms infest timber furniture. The pests prefer warm, damp and moist places to hide and live. Rotting timber is easier to drill through and offers favourable conditions to the woodworms, which can cause damage for thousands of pounds.
  • Preferences for different types of wood: Some species of beetles prefer softwoods such as eastern white pine and European spruce. Others would rather feed on hardwoods like oak, cedar, birch or mahogany. So, no matter what type of wood your furniture is made of, it can fall under woodworm infestation.
  • Fungal problems: mould and mildew are the worst nightmares of wooden furniture because they will destroy the structure’s integrity. By this, the timber will get softer, and the woodworms can easily dig into it.
  • The wooden material at your property is not treated: another premise to welcome the unwanted beetles. It’s very important to take care of the furniture, like cleaning it regularly with non-abrasive products, especially when it’s timber.

Signs of woodworm

You will often see the furniture turning dark from a woodworm infestation, having lots of holes, hearing cracking noises coming from the furniture, and finding one or two live beetles.

How to tell if a woodworm is active?

It is a common misconception that once you see holes in the wood, it means the woodworm has grown up and left the nest. However, it is possible that the same now grown-up beetle will return to the place it once occupied and lay eggs there. This will make your furniture a breeding ground for these wood-boring insects.

Instead, you should look for an adult carcass, freshly ejected frass, and the number and density of holes.

How to get rid of woodworm naturally

So, after you’ve identified the presence of the beetles, you’re ready to take further action and treat them. We’ll cover some DIY non-toxic woodworm treatment methods that might work for your problem.  


Place the infested item in the freezer if possible. It’s effective for a furniture item that is small enough to be placed in your freezer. For example, if you have a small table that can be disassembled and fit inside, you can try this method:

  • Wrap it in plastic bags so that the item is well covered.
  • Leave the infested items in the fridge for at least seven days.
  • Take them out and wait to revert back to room temperature, as watermarks can occur.

The risk this method hides is that your furniture might lose its structure and collapse after a while. So, we recommend trying this with high-quality timber and covering it very well with plastic bags.


Another alternative for treatment without using any chemicals is to submit the affected furniture to heat. What you have to do is to:

  • Isolate all infested wooden items in a small room or a closet and heat the furniture up to 50°-60°C. You can use an electric heater, electric radiator, convection heater, and any other appliance you own.
  • Leave the items heated for at least two hours to completely eradicate the larvae and adult beetles.

Even if this approach is highly efficient, it also hides some dangers. We don’t recommend applying it on antiques and valuable items because you can damage them. Instead, leave this task to experienced specialists.

Keep humidity at low levels

As we’ve mentioned above, beetles love highly moisturized timber. For that reason, keep the humidity at low levels, perfectly at 40-50%, that you can measure with a hygrometer. What you can do is to:

  • Ventilate with the help of exhaust fans;
  • Open windows regularly;
  • Use a dehumidifier;
  • Keep plants that absorb humidity indoors;
  • Leave clothes outside to dry or use a dryer.

Try boron woodworm treatment

The boron solution is a widely known way to get rid of woodworms in furniture. Unlike many other insecticides, this one is great as it’s a water-based product and is considered eco-friendly. Doesn’t leave unpleasant odours and dries quickly into the wood.

Depending on your infested items, the solution will include different amounts of boron and water. If you get powder, you will need around 5% of it relevant to the quantity of water to apply two layers. Leave the first coat to dry well before applying the next one. For example, for 10 sq m, you will need 200grams of the Boron mixed into 5L of water. You can spray the affected surface or apply the solution with a sponge.

It’s preferable to protect your skin with gloves, as more sensitive people might be irritated by the product.

Block woodworm holes

To cover all holes, you can apply glazing shellac. This will hinder the growth of larvae and make their emergence a lot harder.
