Kill Insects inside wood using Injectors - for timbers over 50mm thick
Injectors - fitted with one-way valves which allow Timber Gel to be forced into the tunnels and chambers where the insects are active - the only effective way to reach Death Watch Beetle and House Longhorn Beetle.

For injection of wood a 10mm diameter x 40mm long hole is required, for flush fitting.

Removing Injectors to finish a surface, after injection for insect attack
If you wish to pull out the injectors with pliers after injection do not bang them all the way in: leave about 15mm protruding from the surface. Otherwise, they can be drilled out and then filled to match the surface by;
1. Using our Mouldable Epoxy Putty - this can be tinted using our Colouring Pigment.
Mixing Mouldable Epoxy Putty.
2. Using our Plastic DPC Plugs - tapered fit, flat topped, hollow, available in dark brown, red brick or limestone colours.
DPC Plastic Plugs to fill 10mm - 12mm holes.
Wood suitable for using injectors
You can inject most types of wood, but be aware that the hole must be deep enough to allow adequate chemical spread.
Allow a minimum of one injector every 110mm along the wood and one line of injectors across the wood grain at 75mm centres.
Death Watch Beetles rarely come to the surface. House Longhorn Beetle also stay mainly inside the wood.

How to inject into Cracks using injectors - summary for a range of crack widths
1. Clean the crack surface using abrasion to prepare for later filling
2. Vacuum to remove all debris
3. Drill 10mm diameter holes at between 50mm and 110mm intervals along the crack lines
4. Blow or vacuum out all the bore dust
5. Bang-in the injectors flush to the surfaces with a hammer
6. Inject either Boron Gel, or Lignum Pro Gel , or Boron Ecobor 20 Brushing Gel , depending on the moisture content of the wood and the type of insect attack.

How to choose a woodworm treatment product for injection through an injector
1. Death Watch Beetle - hollow when 'tapped' areas, test drilled. Tapping noises heard inside.
Damp Timber - over 16 - 18% moisture content - wood particles from drillings feel damp to the touch.
Use Boron Ecobor 40 Gel from a 400cc cartridge tube ejected into an empty 50ml syringe. Place the syringe tip firmly into the injector and gently push the plunger - you will use very little Boron Gel, so go slowly. Stop when the syringe plunger will no longer depress. Move to the next injector. Boron Gel likes dampness. It does not spread so well well inside 'dry' wood.
Usage rate - use our chart of hole spacing for various timber sizes as a guide, or call us on 01626 872886 and we'll calculate your exact requirements. (Hole Spacing Guide - click here to download)
Dry Timber - below 16% moisture content - wood particles from drillings feel dry to the touch.
Use Lignum Pro Gel from a 400cc cartridge tube ejected into an empty 50ml syringe. Place the syringe tip firmly into the injector and gently push the plunger - you will use very little Timber Gel, so go slowly. Stop when the syringe plunger will no longer depress. Move to the next injector. Lignum Gel likes dry wood. It does not spread as well inside 'damp' wood.

Very Dry Timber - below 12% moisture content - wood particles from drillings feel very dry to the touch.
Use Boracol 10 from a 5 litre can sucked up into an empty 50ml syringe. Place the syringe tip firmly into the injector and gently push the plunger - you will use very little Boracol, so go slowly. Stop when the syringe plunger will no longer depress. Move to the next injector. Boracol 10 likes dry wood, but will also spread well inside 'damp' wood.

Place the syringe tip firmly into the injector and gently push the plunger - you will use very little Timber Gel, so go slowly. Stop when the syringe plunger will no longer depress. Move to the next injector. Lignum Gel likes dry wood. It does not spread as well inside 'damp' wood. It is a Permethrin based cream emulsion.
