Borer Control Melbourne from Exopest

Anobrium Borers are commonly found in Baltic pine floors and cupboards, as well as occasionally in radiata pine floorboards. Anobium borer do not attack hardwood timbers. The flight holes (1-2mm) resemble small nail holes, which when sanded appear as squiggly lines on the surface. The larva makes the dust or frass that comes out of these holes; the frass appears grain like (when rubbed between your fingers it has a gritty feel). The frass is chewed wood fragments.

When it comes to Anobium borers, they only attack softwood timbers and since the majority of structural timbers are hardwood, structural damage is limited.

Treatment options: include contacting Exopest for advice on treating softwood timbers, sub floor borer inspection, replacing severly infested damaged timbers with hardwood, increasing under floor ventilation and reducing moisture and dampness in subfloor spaces. Treatments include surface application using Boracol 200H or Perigen 500 to effected timbers. Ideally both sides of the infested timber are treated for optimal control.

The borer life cycle is approx 3 years from egg, larva, pupa to adult. The adult Anobium borer only lives a few days and after emerging from its exit hole (flight hole) in the timber it quickly finds a mate to breed and lays eggs. The longest stage of the borer life cycle is spent as a grub or larva in the effected timber and it is this that causes structural damage to the timber. The larva stage is spent entirely in the wood and lasts not less than 2 years.
