House longhorn beetle: signs and dangers
The longhorn beetle is a wood-boring insect that lays its eggs in wood. Thousands of species of longhorn beetles exist worldwide, most of which are harmless and mainly nest in trees or moist wood.
The real problem arises when the house longhorn beetle starts nesting in dry wood, such as in load-bearing beams, floors, and wooden structures of homes. The larvae that emerge from the eggs eat their way through the wood for years and can cause serious structural damage.
Because the longhorn beetle reproduces quickly, a small infestation can rapidly grow into a major plague. Early detection and professional control are therefore essential to protect your home. At Solusio, we have the right expertise and treatments to control longhorn beetles effectively and sustainably.


How Do We Approach Longhorn Beetle Control?
Longhorn beetle control requires a thoughtful and professional approach. The larvae nest deep in the wood and can only be effectively controlled with specialized oil-based agents.
At Solusio, we only treat the infected zones, so that unnecessary wood surfaces are not affected. We often drill small openings in the affected beams, into which we inject a control agent under high pressure. This way, the product penetrates deep into the wood, exactly where the larvae are located.
With a light infestation, one treatment may be sufficient. In the case of a heavier plague, we provide follow-up with a repeat treatment, so that we are certain that all longhorn beetles are completely eradicated and your woodwork remains sustainably protected.
What is the Difference between a Woodworm and a Longhorn Beetle?
Many people confuse woodworm with longhorn beetle, but there is indeed a difference. The woodworm is usually the larva of the house longhorn beetle. While the longhorn beetle itself only makes a few bore holes to lay eggs, it is the larvae, the woodworms, that cause the real damage. They feed continuously on the wood for years and can seriously damage the load-bearing structure of a home.
Because longhorn beetles reproduce quickly and multiple specimens can nest in the same beam or floor, a small infestation can rapidly grow into a serious woodworm plague. Unlike outdoors, where natural enemies such as birds or other insects keep the population under control, longhorn beetles have no natural opponents in homes.
Therefore, it is crucial to have a professional control carried out immediately at the slightest suspicion of longhorn beetle or other wood insects. This way you avoid the damage growing unnoticed and ultimately bringing high repair costs.


How to Recognize a Longhorn Beetle?
Not every longhorn beetle causes damage. There are both wet wood borers and dry wood borers. Wet wood borers mainly occur in trees and do not need to be controlled. The dry wood borers, on the other hand, including the well-known house longhorn beetle, are dangerous and can cause serious damage to wooden structures in homes.
You can recognize a longhorn beetle by the following characteristics:
-
Black color
-
6 legs
-
Length of approximately 10 to 20 millimeters
-
Narrow and elongated body
-
Two remarkably large antennae on the head
-
A soft gnawing sound that is audible when the larvae bore through the wood
Do you recognize (one of) these signals in your home? Then there’s a good chance you’re dealing with a longhorn beetle infestation. Quick action and professional longhorn beetle control are necessary to prevent further damage to your woodwork.
Frequently Asked Questions about Longhorn Beetle Control

What is the Price of Longhorn Beetle Control?
The cost of longhorn beetle control doesn’t always have to be high. Everything depends on the severity of the infestation and the condition of the wood. At Solusio, an experienced expert always visits free of charge to analyze the situation. Based on this visit, you receive a clear price estimate, fully tailored to your situation.
Factors that influence the price include:
-
The extent of the longhorn beetle infestation
-
The accessibility of the infected zones
-
The number of affected wooden beams or surfaces
-
The duration and intensity of the treatment
-
Any additional measures, such as wood repair or preventive treatments against recurrence
Thanks to this personal approach, you never pay more than necessary, and you are assured of a sustainable solution against longhorn beetle.
Can You Control Longhorn Beetle Yourself?
In theory, you can try to control longhorn beetle yourself with do-it-yourself products, but in practice this is rarely effective. The larvae of the house longhorn beetle sit deep in the wood and are hardly reachable with surface treatments. This makes the problem seem temporarily solved, but there’s a good chance the plague will return quickly and cause even more damage.
A professional longhorn beetle control is therefore the safest and most sustainable choice. At Solusio, we use specialized agents and techniques that penetrate deep into the wood and completely eliminate the larvae. This way you can be sure that your home really remains free of longhorn beetle and you avoid expensive repairs in the long term.

How Do I Know if I Have Longhorn Beetle in My House?
A longhorn beetle infestation is not always easy to recognize. Typical signals are small oval bore holes in the wood, fine wood dust on the ground, and a soft gnawing sound. Additionally, the wood may sound hollow or lose its strength. Do you see one or more of these signs? Then there’s a good chance that longhorn beetle is present.

Is Longhorn Beetle Dangerous for My Home?
Yes. The larvae of the house longhorn beetle eat their way through wooden load-bearing structures such as floors, roof trusses, and beams for years. This often happens invisibly, so the damage is only discovered late. Serious infestations can even threaten the stability of a home.
👉 With a timely and professional treatment, you prevent irreparable damage and expensive repairs.
