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 ...
Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
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 ...
Inhalation of bleach fumes can cause mild irritation of the upper airways. [38] Personal protective equipment should always be used when using bleach. Bleach should never be mixed with vinegar or other acids, as this will create highly toxic chlorine gas, which can cause severe burns internally and externally.

Machine translation, like DeepL or Google Translate , is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Museums and universities that want to keep their archives bookworm free without using pesticides often turn towards temperature control. Books can be stored at low temperatures that keep eggs from hatching, or placed in a deep-freezer to kill larvae and adults.
Thallium compounds such as thallium sulfate have been used for impregnating wood and leather to kill fungal spores and bacteria, and for the protection of textiles from attack by moths. [24] Thallium sulfate has been used as a depilatory and in the treatment of venereal disease, skin fungal infections, and tuberculosis.
