Furniture Beetle – Anobium punctatum:
Furniture beetles infest softwood timbers and occasionally the sapwood of some of the hardwoods. The most common encounter in urban pest control is in floorings and furniture. They are usually noticed in timbers of some age, at least 7 years old, but commonly over 20 years in service.
There are no effective ways to determine present or past activity during inspections. Test samples would only give findings on those particular samples, not the entire floor. They should always be considered active. It can not be said that borers are "inactive" or that there is "old borer damage" even after a treatment.
The Life cycle of the borer is 1-6 years, adult size is 2.5–4.5 mm. They lay 50-100 eggs in open joints, cuts, rough edges, or old flight holes. Their holes are around 1.5–2 mm in diameter. Damaged timbers have a honey comb appearance, with gritty frass being present. In moist conditions, the life cycle can be as short as 1 year and in drier conditions can extend to 6 years (in Sydney usually 3 years). The beetle usually emerges in October to November, but this may vary with weather conditions.
