Remove woodworm biologically, chemically or physically

Depending on the location of the infestation, the size, handiness and mobility of the wooden object and the accessibility, different methods and means are available to remove woodworm. Biological and physical methods are increasingly being preferred to the use of poison and chemical "clubs".

Damage determination and intervention planning

Which method is chosen to remove woodworm depends on a few basic parameters: H

  • Which and how treated (paint, varnish, varnish) wood species is affected?
  • How thick or strong are the wooden components?
  • Is the wood installed indoors or outdoors?
  • What is the extent of the infestation from partial to complete?
  • How is the accessibility of the wooden components designed?
  • Is mobility provided by smaller dimensions and movement (furniture)?
  • How much should the control method cost?

Methods and tools at a glance


Fighting and eliminating the woodworm with heat is possible thanks to its relatively sensitive protein body in several ways. It is crucial that the larvae are exposed to the minimum temperature of 55 degrees Celsius for more than one hour.
This is possible with a conventional hair dryer at least partially and not too thick or unreachable wooden components. Smaller items can be placed in a microwave. In a few minutes, the rays provide for the degeneration and death. Professional suppliers "pack" the attic or the entire building airtight and heat it throughout.


Cold below minus 18 degrees has a similar lethal effect on woodworm. A larder and a beetle can be killed in a refrigerator (butchery) or a suitable size in a freezer or freezer in about 24 hours.


Similar to professional heating, a roof truss or building is packed airtight and the wood worm is gassed. The volatile toxic gases argon, carbon dioxide, nitrogen or sulfuryl difluoride are introduced.

home remedies

The woodworm can be combated with several home remedies. The effectiveness depends on the intensity of the infestation and the accessibility of the wood substance. Classic tools for treating are boron salt, vinegar, cleaning alcohol or isopropanol and outdoor alcohol.


Woodworms and related insects also communicate acoustically. Knocking and noise disturbs her. This property can be used to drive off the insects. Regular knocking at intervals or setting up wooden-contact loudspeakers can drive visitors away. The tones should be set to the lowest possible frequencies.


With the much quoted tip to use acorns against woodworm, at least in combination with other methods interesting tool is available. Woodworms love the scent of the acorns and settle on obvious offer quickly. The then acutely infected acorns are burned.

Tips & Tricks

Use biological control methods as intensively as possible, following physical forms and only in extreme cases chemical agents.
