Wood Boring Insects: How to Identify and Treat Them

Wood-boring insects can cause severe damage to your property if left untreated. These insects lay their eggs in cracks and crevices in timber, and the larvae feed on the wood as they grow.

Fortunately, some telltale signs can help you identify whether your property is infested with wood-boring insects.

In this blog post, we’ll discuss some signs of a wood-boring insect infestation and what you can do to treat it.

Signs of a Wood-Boring Insect Infestation

Wood boring insects typically lay their eggs in cracks and crevices in timber.

As the larvae develop, they feed on the timber, causing severe damage. Some of the signs that you may have a wood-boring insect infestation include:

  • Finding the Wood-Boring Beetle Eggs

A wood-boring beetle goes through four phases in its life cycle: eggs, larvae, pupae, and adults. Pupae and eggs do not eat. Although some kinds of beetles can destroy wood as adults, it is usually the larvae, or grubs, that do the most harm. Most wood-boring beetles don’t harm finished wood goods or seasoned structural timbers.

However, if left untreated, they can cause extensive damage to furniture and other wooden items in your home. If you’re concerned about wood-boring insects causing damage to your home, you’ll be relieved to know that there’s a simple way to check for their presence. Simply lift a piece of timber and look for small holes—these are where the beetles are laying their eggs.

Call in a specialist to inspect if you’re concerned that you could have an infestation. They will be able to determine whether or not you have an infestation by looking for adult beetles. After that, they will give you advice on the best course of action.

Additionally, they will be able to remove the adults to prevent further harm to your property.

  • Emergence Holes Found on the Timber in Your Property

Have you noticed small holes appearing in the timber of your property? Another sign of a wood borer infestation is emergence holes. As adults emerge from tunnels in the infested material, they leave holes in the surface of their tunnel system; these are known as “emergence holes.” The damage caused by these adults is usually minor and not noticeable unless you’re looking for it.

However, if you’re looking to treat an infestation, then you will need to repair any damage caused to surfaces where the adult beetles have emerged. To do this, use a filler that matches the grain of the damaged area to blend the hole back in with the surrounding surface. Then sand down this repair until it is flush with the rest of the timber’s surface. This will give your property a fresh finish again!

Additionally, you can always contact a professional to help you deal with the issue. They are trained to identify the cause of the damage and can advise you on the best course of action to take to prevent further damage to the property, such as timber treatments. After all, they’re the experts!

  • Frass Found Outside Your Woodwork?

When insects like woodworm make their homes in the wood of your house, one telltale sign is the presence of frass, the waste product of wood borers, outside your woodwork. This type of waste is typically found in piles of sawdust that are usually found near the exit points of the tunnels in the infested material. These piles look like sawdust and can be confused with sawdust caused by other kinds of household pests, such as carpet moths and woodlice.

More harm can be done by these pests the longer you let them stay in your timber. The wood may become weaker from the insects’ tunnelling, reducing its strength and necessitating expensive repairs. Keep an eye out for frass and deal with it right away to prevent insects from ruining the structural integrity of your house.

Make sure a professional expert has inspected and repaired your timber so they can get rid of any infestations.

  • In Some Cases, People Hear a Slight Noise Coming From the Timber Itself (this is the Telltale sign of the Death Watch Beetle)

The common name for a type of wood-boring beetle that attacks the structural timbers of old buildings is “Deathwatch Beetle.” The brown adult beetle is around 7 mm long on average. In old wood structures, trees, and tunnel systems left behind by previous larvae, eggs are placed. A Deathwatch beetle’s major problem is widespread tunnelling within the wood of your property, which compromises the wood’s structural integrity and can result in degeneration or complete failure.

So how do you know if these insects are present in your building?

Infestations of Deathwatch beetles can be difficult to spot as they generally prefer darker areas where they may be hidden under floorboards or behind skirting boards. If left undetected, the damage caused by these insects can weaken the structure of your property and lead to expensive repairs or even the need for complete replacement of the infested areas. If you can hear a slight ticking noise coming from your floorboards, this is a sign that you have a Deathwatch beetle problem that needs to be dealt with as soon as possible!

Fortunately, early detection and pest control measures can eradicate death watch beetle infestations before they wreak havoc on your property. Regular inspections and maintenance can help to catch and prevent such infestations. If you suspect you have an infestation, contact a professional right away; they will be able to address the problem for you quickly and efficiently!

Treating a Wood-Boring Insect Infestation

When it comes to treating wood-boring insects, many homeowners immediately turn to chemical treatments.

While these products can be effective in killing pests, they also have the potential to harm people and pets if not used properly. It’s important to always adhere to the manufacturer’s instructions and take appropriate safety measures, such as ventilating the area after applying the treatment. If you’re unsure about using chemicals, it may be wise to hire a professional company for its expertise and experience.

Either way, it is essential to treat wood-boring insects promptly before they cause further damage to your property. Prevention is also key; sealing cracks and holes in your home’s exterior can help prevent infestations from occurring in the first place. Overall, proper caution and care should be taken when dealing with wood-boring insects and their chemical treatments. Wood-boring insects can wreak havoc on your wooden structures, causing costly damage.

Thankfully, there are several chemical treatments available to combat these pests.

Physical Removal

Another option is to physically remove or destroy any infected materials. This may not always be possible—for example, removing sections of flooring that are infested with beetles—but you may be able to remove them if the affected material is removable. Any infested furniture can be discarded, and the affected sections of the wall can be sanded down and repainted. Removing the affected material can help stop the spread of the pest and prevent it from causing further damage to your property. You should call in a professional if you suspect you have an infestation because they’ll be able to advise you on how to fix the problem safely!

Keep in mind that, depending on the severity of the infestation, physical removal may not always be enough on its own; it may need to be combined with other pest control measures such as chemical treatments or the replacement of timber. It is essential to weigh all options and carefully consider the potential risks and benefits before deciding how best to tackle a wood-boring insect infestation.

It’s important to consult with a professional before taking any drastic measures; they may be able to suggest alternative methods, such as treating the infestation with pesticides or finding and eliminating their source of food and shelter. Take the time to consider all potential solutions before making a decision.


Wood-boring insects can cause severe damage to your property if left untreated. If you think you may have an infestation, it’s essential to take action immediately by identifying the type of insect and choosing an appropriate treatment method.

Chemical treatments and physical removal are two standard methods for treating wood-boring insect infestations. Always read and follow the manufacturer’s instructions carefully when using chemicals, and be sure to ventilate the area well after applying them.
