HOW TO TREAT DEATH WATCH BEETLE PROPERLY - surface treatment alone does not work

1. Tap the beams with a hammer and listen for changes in note. Listen late at night for 'tapping' sounds - Death Watch beetle mating noises (perhaps they need longer beds?)

2. Drill test suspicious areas with a wood Auger to determine the extent of the attack zone. We suggest using an 8mm diameter Auger. Examine the bore dust for signs of beetle 'frass' - this is the insect's bore dust and no wood fibres will be found in these parts.

3. For valuable beams consider using our Ultra Sound and Resistograph testing service.

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

5. Remove any residual surface stain, paint, wax or varnish. No surface chemical treatment will penetrate these finishes.

6. Brush and vacuum clean, to remove all the dust and debris.

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.

9. Apply Boron Ultra Paste by injection, to damp areas, like those embedded in the wall.

10. Apply Ultra Timber Paste, by injection, to dry areas, like those not embedded in the wall.

Treating Historic or beautiful finishes for Death Watch Beetle

You will have to delete steps 4, 5, 7 and 8 above - go straight to step 10.

Check for fresh Death Watch Beetle holes 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. Listen for the distinctive tapping sounds.

Natural Fire Retardant

Boron Ultra 12 has natural Fire Retardancy properties and this is an obvious benefit when you are treating wood in buildings. The Boron compounds are frequently used in many industries to provide Fire Retardant properties, for example in board products and building materials. .

Added Fire Retardancy - to further reduce the fire risk in your building you can now buy our Fire Retardant Additive to pour into your Boron Ultra 12. It has no odour or hazards and simply boosts the natural fire retardancy without affecting the woodworm treatment.


2. BORON ULTRA GEL - Surface Applied by brush - for damp and dry wood

A Boron based brushing Gel ideal for damp stained wood, end grain and bearing area treatment of beams and joists. Also useful for medium to heavy active infestations of insect attack and treatment of new timbers for use in vulnerable areas (e.g. back of skirting boards). Apply to bare surface timber as part of the control of Death Watch Beetle.

3. BORON ULTRA PASTE - Deep Injected Treatment - for damp wood

A unique Boron based Paste, which uses a special blend of technical grade Glycols as carriers. It can be injected into timber, with the advantage of supplying a highly concentrated mobile preservative which will spread even at low (down to 12% TMC) moisture content levels. Simple to apply with a standard skeleton gun and highly effective because of the available level of active Boron content deep inside the wood. It is injected into 8mm diameter holes at up to 120mm along the grain, 75mm across the grain and down to within 15mm of the opposing side of the timber (see hole Spacing Chart). Essential for the control of Death Watch Beetle in damp or wet wood, especially in embedded timber beams and joists sitting in or on a wet wall, because it also kills wood rotting fungi, like Wet Rot and Dry Rot.

4. ULTRA TIMBER PASTE - Deep Injected Treatment - for dry wood

An alternative treatment for drier timber (under 12% TMC) - Permethrin in an emulsion cream base. Has some odour and solvent. Do not use in buildings housing fish or birds. Essential for deep seated active Death Watch Beetle, or the voracious House Longhorn Beetle, where the moisture content of the wood is too low to spread the Boron based paste. Essential for the control of Death Watch Beetle in dry wood, where Boron based Paste will not spread quickly.
