Wood Boring Insects Remedial treatment usually involves the controlled in-situ treatment of infested timbers with an insecticide approved under the Control of Pesticides Regulations 1986. This can be in the form of paste or a soulution applied by a brush, spray, or otherwise as appropriate. Occasionally, remedial treatment may involve the replacement of structurally impaired timber with suitable pre-treated wood.

Dry Rot In buildings, the only 'cause' of dry rot is dampness. In the control of dry rot, the first step is to eliminate the source of moisture by identifying and correcting the source of water penetration, i.e. by repairing leaks in roofs, plumbing, by drying out masonry, or by installing an effective damp-proofing course. All the structurally unsound timber should be removed and replaced with pressure impregnated sections. Affected masonry surfaces may also be treated with a fungicide.

Wet Rot This is the most common form of wood decay in buildings, affecting both joinery and structural timbers. As with dry rot, wet rot is caused by a high moisture content in the timber.
