House longhorn beetle treatment: identify and eliminate

How to recognise the house longhorn beetle?

  • Oval exit holes of 6 to 10 mm in the roof frame, beams or softwood timbers
  • Frass and sawdust at the foot of the infested timbers
  • Clearly audible gnawing noises, especially at night and in calm weather: house longhorn beetle larvae bore noisily
  • Oval galleries under the surface of the wood, packed with compacted frass

The house longhorn beetle mainly targets softwoods: roof frames in pine, fir or spruce. Maritime pine, found everywhere around the Bassin d'Arcachon, makes this one of the most exposed areas in France.

House longhorn beetle larva in its galleries at the heart of a beam
The house longhorn beetle larva bores its galleries deep inside the wood for 3 to 10 years, invisible from the outside.

Is the house longhorn beetle dangerous for a roof frame?

It is the most destructive wood-boring insect for roof frames. Its larva bores through the wood for 3 to 10 years before becoming an adult: all that time, it hollows out the beams from the inside with no visible sign. A heavily infested roof frame can lose its load-bearing capacity, with a real risk of collapse. That gnawing noise you hear is larvae boring right now: every day counts.
