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
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 ...

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 beetle does not infest wood that has recently died; about sixty years must pass for dead oak to reach a suitable condition for attack. [4] These beetles tend to stay on the same piece of wood for several generations until resources are used up and the piece of wood is no longer sufficient.
The bites may be pimple-like, blister-like or similar to hives. They typically appear in specific areas on the lower body where tight clothes meet skin, like at the cuffs of your socks or the ...
In spite of their slender, worm-like forms, shipworms possess the characteristic morphology of bivalves. The ctinidia lie mainly within the branchial siphon, through which the animal pumps the water that passes over the gills. The two siphons are very long and protrude from the posterior end of the animal. Where they leave the end of the main ...
