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 lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
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
In other cases, termites, carpenter ants, and woodboring beetles will first infest wooden bookshelves and later feed on books placed upon the shelves, attracted by the wood-pulp paper used in most commercial book production. True book-borers are uncommon.
Decayed wood is also much easier for the larvae of the deathwatch beetle to bore into which allows them to develop at a faster rate. [5] The sapwood is more nutritious and is usually attacked first, followed by heart wood that has been softened by decay. Oak (Quercus spp.) is the main host, with American oaks being more susceptible than ...
Hodotermes (from Greek ὁδός (hodós), travelling; Latin termes, woodworm) is a genus of African harvester termites in the Hodotermitidae.They range from Palaearctic North Africa, through the East African savannas to the karroid regions of southern Africa.
Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
An old woodworm who lives in a small piece of wood, near the top of a mountain, tells the story of his ancestors on their journey on the ark. Willi, the oldest ancestor in the old worm's family tree, lives in a hole in a trunk, alongside his wife, Alice. One day, while both of them are eating in their house, it starts shaking.
