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.
This includes a number of subfamilies including Ptininae, the spider beetles which are mostly scavengers, Anobiinae, wood-boring beetles, and Ernobiinae, deathwatch beetles, also wood-borers. In 1912, Pic erected Ernobiinae for beetles previously classified under Dryophilini by Fall in 1905. White elevated this taxon to subfamily status in 1962 ...
The common furniture beetle or common house borer (Anobium punctatum) is a woodboring beetle originally from Europe [1] but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult Anobium punctatum measure 2.7–4.5 millimetres (0.11–0.18 in) in length.
Some species are parasitic, causing decay in living trees and damaging timber structures such as houses and ships. Wood boring activities occur primarily in the larva stage, with the larvae damaging both sapwood and heartwood. Lymexylidae larvae bore into living and decaying wood where they consume the fungus Alloascoidea hylecoeti. [1] [2]
Lyctus carbonarius is a wood-boring beetle in the family Bostrichidae (formerly in the family Lyctidae, which is now a subfamily of Bostrichidae), commonly known as the southern lyctus beetle. It is a serious pest of hardwoods including ash, hickory, oak, maple and mahogany and can infest many products in the home including hardwood flooring ...
Other signs of Ips infestation include particles of wood dust accumulating on the bark, foliage, and nearby objects as a result of the beetles' tunneling activity. The wood dust can mix with resin that bleeds from the injury site, creating whitish or reddish pitch tubes, [6] but these are more common in Dendroctonus infestations. [3]
The adult wood-boring beetles lay their eggs in a crevice in the bark of hardwood trees, such as Oregon ash, New Mexico willow, and California laurel/Oregon myrtle. [1] From there the larvae bore into the wood.
