Old-house Borer

The old-house borer is a type of wood-boring beetle in the family Cerambycidae (longhorn beetles). Converse to its name, it is more often found in new houses; this is in part because new home creation may use wood infected with the beetle's eggs. Originating in Europe, the old-house borer now has a world-wide allocation, including the Mediterranean, South Africa, Asia, USA and Canada. Recently it has been found in Perth, Australia.

Old-house borers prefer experienced softwoods, and particularly sulk. Only the larvae feed on the wood. Larvae take two or three or more years to mature, depending on the damp content of the wood. Larvae usually mature in the spring, and the mature adults then cut holes 6–10 mm (¼ to 3/8 in) in distance to exit the wood. Adults are most active in the summer.
