Wykabor 10.1 - Boron Wood Treatment

Wykabor 10.1 is an aqueous wood preservative based on disodium octaborate and benazalkonium chloride used for the treatment of Woodworm and Dry Rot on Timbers. 

When used as a woodworm treatment, Wykabor 10.1 is effective against Common Furniture Beetle (Anobium Punctatum) and other wood boring insects in building timbers.

Wykabor 10.1 is also used for the prevention of fungal decay (Dry Rot) in sound timbers following the removal of moisture.

Wykabor 10.1 Boron Wood Treatment may also be used in conjunction with Wykabor 40.1 as part of an eradication treatment against fungal decay.

Wykabor 10.1 Boron Wood Treatment is approved for Professional Use under The Control of Pesticides Regulations 1986. Read the label before use.

All bats are protected under The Wildlife and Countryside Act 1981. Before treating any structure used by bats, consult English Nature, Scottish National Heritage, The Countryside Council for Wales or The Department of the Environment for Northern Ireland.

Preparation - Beetle Infestations:

Ensure that all timbers to be treated adequately exposed and cleaned, (vacuum cleaning preferred). Any paint or varnish finishes or any severely damaged sapwood edges of timbers (‘frass’) should be removed prior to treatment where possible.

Remove thermal insulation in roof spaces (or roll up and completely cover) and do not reinstate until timbers are dry.

Cover fitted insulation (lagging on pipes) with polythene and cover water storage tanks with heavy grade polythene to be left in-situ after treatment.

Isolate electrical circuits in the treatment area during and for 8 hours after treatment and ensure that junction boxes etc. are adequately protected against the ingress of the fluid. Remove or cover all food-stuff before application as well as fish tanks / bowls.

Do not apply to surfaces on which food is prepared or stored.

Where applicable, notify occupants of adjoining properties before treatments commence.

Display Safety Notices conspicuously during treatment and leave on site after treatment for at least 48 hours.

Preparation - Fungal Decay - Dry Rot / Wet Rot:

Same as (Beetle Infestations) above plus - locate and rectify the source of dampness.

Cut out all structurally unsound timbers and make repairs isolating timbers where possible from damp masonry etc. and ensuring adequate ventilation.

For treatments of decayed timbers in-situ see Wykabor 40.1.

Application Method:

Wear suitable protective clothing (coveralls), synthetic rubber/PVC gloves and face protection.

Wykabor 10.1 can be applied to timbers by brush or coarse spray (low pressure; 210-350 kPa, 30-50 lbs/in²) or by immersion (minimum 3 minute dip) to achieve the coverage rates noted below.

During spray application some respiratory / face protection will normally be required.

In the case of timber sub-floor areas, the base of the structural walls, sleeper walls and oversite (solum) should be treated with Wykabor 10.1. If dry rot mycelium has spread beneath a concrete floor or into subsoil it should be excavated and replaced following a suitable surface treatment .

Provide adequate ventilation following treatments and maintain as long as possible after re-occupation.

Please note that any metallic surfaces (such as copper pipes) should be isolated from the treatment area as the boron salts may cause a chemical reaction causing surface pitting of the metal.


By Brush / Spray: 1 litre per 4m² of timber surface.

By Dipping: Approx. 5 - 20 litres/m³ (dependant on timber dimensions etc).


As long as timbers are dry, re-occupation can take place 48 hours after treatments are completed.

Floor coverings should not be laid for at least 72 hours (or longer for certain impermeable or other floor materials, e.g. vinyls, foam-backed carpets etc.) In all cases, use lining papers to protect coverings from direct contact with timbers.

Treated timbers can be over coated when dry with a range of decorative / protective paints etc. (to ensure compatibility check a small area first).
