- surface treatment alone does not work, because these insects rarely visit the
timber surfaces. Do not pay for surface treatment - Death Watch Beetle needs internal
treatment and an annual check-up, with possible re-treatment.
Tap the beams with a hammer and listen for changes in note. Listen late at
night for 'tapping' sounds, when there are fewer background noises - the tapping
sounds are Death Watch beetle mating noises (perhaps they need longer beds?)
Drill test suspicious areas with a wood Auger (fully flighted wood drill) to determine
the extent of the attack zone, using an 8mm diameter Auger. Examine the bore dust
for signs of beetle 'frass' - no sound wood fibres will be found in these parts,
just bore dust.
For valuable beams consider using our Ultra Sound and Resistograph testing service.

Clean off all loose wood, surface 'frass' and tunnel material to reach sound timber.
Remove any residual surface stain, paint, wax or varnish. No surface treatment,
no matter what chemical you use, will penetrate these wood finishes.
Brush and vacuum clean.
Ultra Gel by brush, if the wood will not require a paint, stain or varnish
finish after treatment.
Apply 2 coats of Boron
Ultra 12 at 5% in water by brush or spray, for wood that you wish to paint,
stain or varnish afterwards. Do not over treat, because you may leave Boron crystals
on the surface, which would stop paints and varnishes from adhering properly.
Ultra Paste by injection, to damp areas, like those timber parts embedded
in the wall (bearing ends).
