Woodworm holes and burrows exposed in wooden floorboard. The first step in pest control is prevention. Particularly important in this respect is to keep the timber dry - below 16% moisture content. A relative humidity within the building above 60% may lead to an infestation, and timber moisture content below 12% is too dry for an infection to ...
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction.

The desire to kill the fungal strands within all materials adjoining the affected timber has led to the practice of "wall irrigation" at stage 4. This entails saturating the masonry with a water-soluble fungicide at a rate of about 10 litres/m 3. Walls of more than half-brick thickness need to be drilled at 230 millimetres (9.1 in) spacing to a ...
