Woodworm has potential to cause structural damage to timbers. This professional woodworm treatment kit eradicates wood boring beetle and protects against future infestation. Use in properties of all ages and sizes to treat unpainted doors, frames, roof timbers, floorboards, joists, rafters. wooden panels and furniture.

The kit comprises:

  • 5 x 1L containers of Lignum Pro I62.5 insecticide concentrate; each making 25L of woodworm fluid when diluted with water (125L total)
  • 1 x 25L mixing/ storage container

Lignum Pro I62.5 is woodworm treatment insecticide formulated with micro-emulsion technology. It has a minute particle size, which is in the nanometre range. This allows the insecticide to penetrate deep into timber in order to eliminate woodworm attack and to safeguard timbers against future wood boring insect infestation.

How to use Woodworm Treatment Kit

  • Open up and make accessible as much timber surface as is practical; e.g. lift some floorboards to gain access to both top and bottom surfaces of timber floors and to flooring joists.
  • Ensure wood surfaces are clean and free from wood dust and other contaminants
  • Use mixing/ storage container to mix 1 litre of insecticide with 24 litres of clean water
  • Decant 5 litres of dilute into the spray unit and pressurise
  • Spray diluted fluid, to all accessible surfaces of the timbers at the applicable coverage rates

Coverage for treating woodworm infestation:

Use 1L of diluted fluid to treat a surface area of 3.3m2 (300ml/m2). Therefore 1 litre of concentrate (25 litres of fluid) treats a total surface area 82.5m2 of infested timber

Coverage for preventing beetle infestation in non-infested wood:

Use 1L of diluted fluid to treat a surface area of 5.0m2 (200ml/m2) Therefore 1 litre of concentrate (25 litres of fluid) protects a total surface area 125m2 of non-infested timber
