Common Questions About Woodworm & How to Get Rid of It ​

Woodworm infestations are a serious and common problem for many homeowners, property managers, and anyone dealing with timber structures. These tiny but destructive pests can really weaken wooden furniture, flooring, and even structural beams if left without treatment.  

Understanding woodworm, how it spreads, and the best ways to treat it is really important for preserving the integrity of wooden structures. We explore some of the most common questions about woodworm and discuss effective woodworm treatment methods, including professional woodworm treatment, woodworm treatment chemicals, and woodworm treatment sprays. 

What is woodworm?

Woodworm is not actually a worm; it refers to the larvae of various wood-boring beetles that feed on timber. These larvae burrow into the wood, creating a network of tunnels that can really compromise the strength and stability of the material.  

When the larvae mature, they come out as adult beetles, leaving behind small exit holes in the wood’s surface. The most common species responsible for woodworm infestations in the UK is the Common Furniture Beetle (Anobium punctatum), but other species, such as the Deathwatch Beetle (Xestobium rufovillosum) and the Powderpost Beetle (Lyctus brunneus), can also cause damage. 

How do woodworm infestations happen?

Woodworm infestations begin when adult beetles lay their eggs on or inside wooden surfaces. When the eggs hatch, the larvae bore into the wood and begin feeding. This feeding stage can last several years, depending on the species and environmental conditions. The larvae then pupate and eventually emerge as adult beetles, ready to reproduce and continue the cycle. If left unchecked, woodworm infestations can spread and cause severe damage to timber. 

What are the signs of a woodworm infestation? 

 

Identifying a woodworm infestation early is important for preventing serious damage. Some common signs include: 

Small, round exit holes on the surface of the wood 

Powdery dust (frass) near the holes, indicating active larvae inside 

Weakened or crumbling timber 

Dead beetles near affected wood, especially in summer months 

Tunnels visible in cross-sections of the wood 

How does woodworm treatment work? 

Treating woodworm effectively involves getting rid of the larvae inside the timber and preventing future infestations. There are several approaches to woodworm treatment, including chemical treatments, heat treatments, and moisture control actions. 

Chemical woodworm treatment: The most common method involves using woodworm treatment chemicals, such as permethrin-based solutions. These chemicals penetrate the wood and kill the larvae while also preventing adult beetles from laying eggs. Woodworm treatment sprays and injection treatments are often used to make sure the product reaches deep into the wood. 

Wood heat treatment process: In cases where chemical treatments isn’t the right action, heat treatment can be a really effective alternative. This method involves exposing the infested wood to high temperatures (typically above 55°C) for a sustained period, which kills all life stages of the woodworm. This is a preferred option for treating antique furniture or delicate wooden artifacts where chemical treatments might cause damage. 

Is woodworm expensive to treat?

 

The cost of treating woodworm depends on the level of the infestation and the treatment method used. Minor infestations affecting furniture or small wooden structures can often be managed with DIY woodworm treatment products from hardware or home stores. However, serious infestations in structural timbers require professional woodworm treatment, which can be more expensive. Getting a professional assessment from a wood rot treatment expert is recommended if the infestation is widespread.

Can woodworm spread to other areas?

Yes, woodworm can spread, especially in damp environments where timber is more likely to suffer an attack. Adult beetles coming out from infested wood can lay eggs on other untreated wooden surfaces, leading to further infestations. Preventing the spread of woodworm involves dealing with these moisture issues, using timber wood treatment to protect exposed wood, and regularly inspecting wooden structures for early signs of damage. 

What is the difference between woodworm and wood rot? 

While woodworm and wood rot both affect timber, they are caused by different factors. Woodworm is an infestation of wood-boring beetle larvae, while wood rot is a fungal issue that occurs when timber is exposed to excessive moisture. 

Dry rot treatment: Dry rot is a type of fungal decay that spreads rapidly and can severely weaken wooden structures. It needs urgent treatment, usually involving the removal of affected timber and use of fungicidal treatments. 

Wet rot treatment: Wet rot happens in persistently damp conditions and leads to the breakdown of wood fibres. Unlike dry rot, wet rot remains confined to the damp area and can be addressed by fixing the source of moisture and using wood rot treatment solutions.

Can I treat woodworm myself? 


DIY woodworm treatment is possible for minor infestations using readily available products such as
woodworm treatment sprays and chemical solutions. When treating woodworm yourself, it is really important to follow the manufacturer’s instructions and make sure it has a thorough application. However, if the infestation is large or affects structural timbers, it is recommended to seek professional woodworm treatment services to make sure you get rid of them fully. 

How can I prevent woodworm infestations? 

 

Stopping woodworm infestations from happening requires a proactive approach. Here are some effective strategies that can help to prevent woodworm: 

Reduce moisture levels: Woodworm larvae thrive in damp timber. Keeping indoor humidity low and making sure that there is proper ventilation can make the environment less attractive to wood-boring beetles. 

Use treated timber: When constructing or repairing wooden structures, opt for pre-treated timber with insecticidal protection. 

Regular checks: Inspecting wooden furniture, flooring, and beams for signs of woodworm can help catch infestations early. 

Fix leaks and damp issues: Dealing with water leaks and damp problems reduces the risk of woodworm and wood rot. 

Are there professional woodworm treatment services?

Yes, professional woodworm treatment services are available for severe or persistent infestations. Experts use special woodworm treatment equipment, such as industrial-grade sprays and injection systems, to target deep infestations. They can also assess the extent of the damage and recommend any necessary structural repairs. Hiring a professional ensures the infestation is completely removed and helps prevent it from returning. 

Woodworm infestations can be a real concern for homeowners and property managers, but with the right knowledge and treatment methods, they can be effectively controlled. Recognising the signs of infestation early and using appropriate woodworm treatment products or professional woodworm treatment services can help protect wooden structures from further damage.  

Whether using chemical treatments, heat treatments, or moisture control methods, it’s important to tackle woodworm as soon as possible to protect wooden structures in homes and buildings. If left untreated, woodworm can weaken timber, leading to expensive damage and potential safety risks. Acting quickly helps prevent the infestation from spreading and causing further harm. If you suspect a serious problem, it’s always best to consult a professional. Experts can assess the extent of the infestation, apply the most effective treatment, and recommend ways to prevent future outbreaks, ensuring your wood remains strong and protected for years to come.
