The borers are 3 to 4 mm long with an obvious, unconcealed head.
The female beetle lays eggs in the end of pores of the sapwood to a depth of 1-3mm. The larvae emerge through round holes about 1.5-2mm in diameter. The life cycle from eggs to adults is completed within 3-12 months.
The borers are pests of structural and joinery timbers in houses and furniture.
They attack both hardwoods and pines. Attack usually occurs during the first few years of the service life of structural and joinery timbers and furniture.
