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 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 ...
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 egg shells and cuticles of the potential hosts are thickened to prevent the parasitoid from penetrating them. Hosts may use behavioral evasion when they encounter an egg laying female parasitoid, like dropping off the plant they are on, twisting and thrashing so as to dislodge or kill the female and even regurgitating onto the wasp to ...
Of the quarter million species of beetles, some adults damage books by eating paper and binding materials themselves. However, their larvae do the most damage. Typically eggs are laid on the book's edges and spine. Upon hatching, they bore into, and sometimes even through, the book. [3] Drugstore beetle on a human finger

A week after swarming, the female lays her first eggs, which are tended by the couple, a task soon taken over by the maturing workers. After some four months, the nest is sufficiently developed to send foraging workers to the surface. For the next few years, most of the eggs develop into workers and a small number of soldiers.
Females are 2–5 mm long; they have a stinger but lack wings. They are black/brown, and have the appearance of ants. Females enter woodworm holes, paralyze the woodworm larvae with the venom of the stinger and lay their eggs in the corpses, which form the food for the S. domesticus larvae. This behavior leads to the common name of "antiquarian ...
