Widely distributed in
temperate climates.
Commonly found in the outdoor
environment where it is part of the natural decay of organic
materials.
Indoors, it may infest almost all
timbers including structural and ornamental. |

A serious
and significant pest of structural and ornamental timber.
Adult forms may enter premises through roof eaves and lofts during
the spring. Long term infestation may threaten even
substantial structural timbers. |

Adults emerge from
timber in the Spring and early summer. Eggs are laid into crevices
immediately after mating, Sawn ends of manufactured timber is an
example of a typical oviposition site.
Females lay around 30 eggs in small
groups. Emergence will occur 2 - 4 weeks later, when the
young larvae will bore into the timber.
Full life cycle indoors takes
between 2 and 4 years. Final instar larvae will tunnel toward
the surface and construct a pupation chamber near to the surface. Adults
emerge, completing the cycle, leaving a characteristic bore hole
and gritty powder in the vicinity of the hole. |

Timbers of limited size
may be fumigated with Methyl Bromide (CH3Br) where applicable,
although a residual treatment is often necessary to provide
ongoing protection for the timber.
Monitoring products for this
organism are available, although they should not be relied upon in
place of a full survey.
Curative treatments are usually
intended to present a toxic surface to female beetles, with the
result of stopping the life cycle at that stage. |
