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
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.
The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a 1 millimetre (0.039 in) long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to 7 ...
The shipworms, also called Teredo worms or simply Teredo (from Ancient Greek τερηδών (terēdṓn) 'wood-worm', via Latin terēdō), are marine bivalve molluscs in the family Teredinidae, a group of saltwater clams with long, soft, naked bodies.
Artemisia absinthium, otherwise known as common wormwood, is a species of Artemisia native to North Africa and temperate regions of Eurasia, [4] and widely naturalized in Canada and the northern United States. [5]
Some such larvae exhibit a superficial resemblance to worms and are the likely inspiration for the term, though they are not true worms. 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 ...
However, wood is not a necessary part of their diet and they can live on the surface both of wooden and non-wooden structures. [4] This photo demonstrates teredo worms do not require wood to survive and can damage non-wooden structures. This photo is of an epoxy-fiber glass vessel. Hole depths were less than 10mm.
A gribble /ˈgɹɪbəl/ (or gribble worm [2]) is any of about 56 species of marine isopod from the family Limnoriidae. They are mostly pale white and small (1–4 millimetres or 0.04–0.16 inches long) crustaceans , although Limnoria stephenseni from subantarctic waters can reach 10 mm (0.4 in).
