Wood Boring Weevil (Pentarthrum huttoni)
This beetle is very distinctive with its long snout; it attacks wood that has rotted either through dampness or poor ventilation. It consumes the soft portions of the timber before progressing on to the harder portions.
In contrast to other wood boring beetles, both the adult and the grub bore, producing tunnels running in the wood grain direction and leaving paper-thin walls between them. Their life-cycle is very short, being less than one year.
The emergence holes are very small, 2 mm in diameter, oval and have slightly ragged edges.
This beetle can also attack plywood due to the fact that it is bonded with animal and vegetable based adhesives.
Solution!
If the timber is still serviceable the treatment is the same as that for Common Furniture Beetle, carried out with high pressure spraying of insecticide, which kills the grubs within the timber. Beetles can continue to emerge up to two years after treatment, however, because they have eaten through the treated timber they are rendered sterile and, therefore, unable to perpetuate the life cycle.
Contrary to popular belief, the whole building does not have to be treated if the infestation is only found in one area.
Gullivers generally use an 1-hour re-entry fluid (which means
you can re-access the area treated as soon as 1 hour after
completion of the spray treatment).
