Where can I buy Death Watch Beetle Treatment?


Q. Why treat Death Watch Beetle?

A. Because, over many years, it's tunnels can severely and rapidly weaken structural beams, sometimes causing collapse. It is often found in timbers that are embedded in walls at their bearing ends, because the insect always starts off in wet rot in timber.


Q. How can I tell that I have Death Watch Beetle?

A. From the noise - you may hear tapping during the night - the "Death Watch" - and from the round holes, which are slightly larger that common furniture beetle.


Q. Can I save beams that are partially eaten?

A. Yes, if you inject Property Repair System's Ultra Timber Paste into the active (listen, tap and drill) areas.

HOW TO TREAT DEATH WATCH BEETLE PROPERLY
Note - 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.

1. 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?)

2. 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.

3. For valuable beams consider using our Ultra Sound and Resistograph testing service. Contact us for details or read our Timber Repair Review. You can request Timber Repair Review, Parts 1 and 2, from us by Post or E Mail, free of charge.

4. Clean off all loose wood, surface 'frass' and tunnel material to reach sound timber.

5. Remove any residual surface stain, paint, wax or varnish. No surface treatment, no matter what chemical you use, will penetrate these wood finishes.

6. Brush and vacuum clean.

7. Apply Boron Ultra Gel by brush, if the wood will not require a paint, stain or varnish finish after treatment.

8. 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.

9. Apply Boron Ultra Paste by injection, to damp areas, like those timber parts embedded in the wall (bearing ends).

10. Apply Ultra Timber Paste, by injection, to dry areas, likely to be those parts clear of the walls.


Historic or beautiful finishes - you will have to delete steps 4, 5, 7 and 8 above - go straight to step 10.

Check annually and re-treat if active. This insect can be a structural hazard to your building, so consult us or a Professional Building Surveyor before carrying out treatment.
