Ambrosia Beetle - Woodboring Weevils - Black Borer Beetle
Woodworm is the wood-eating larvae of many species of beetle. It is also a generic description given to the infestation of a wooden item (normally part of a dwelling or the furniture in it) by these larvae. 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 are typically 1mm to 1.5mm in diameter for the most common household species, although they can be much larger in the case of the house longhorn beetle. Adult beetles that emerge from wood may also be found in the summer months.
Typically the adult beetles lay eggs on or just under the surface of a wooden item. The resulting grubs then feed on the wooden item causing both structural and cosmetic damage. They then pupate and hatch as beetles that then breed, lay eggs and repeat the process, causing further damage. Depending on the species involved, woodworm infestation is generally controlled with insecticides.
