Wood Borer Species

Wood damaging pests can attack expensive antiques and even a building’s structural components. Knowing the type of wood boring beetles involved can help determine the most effective control methods.

Longhorn Beetle

(Cerambycidae)

Appearance

  • Adult beetle is 10–25 mm in length. 
  • Black/brown colour with greyish hairs and 2 black spots on thorax which resemble eyes. 
  • Larva is greyish white in colour and can grow up to 35 mm when fully developed.

Habits

  • Female lays eggs in cracks and crevices of wood. 
  • Larva tunnels between sapwood and bark; subsequently moves deeper into the wood as it matures. 
  • Larva creates a hole before it pupates and leaves wood fibres out of the hole. 
  • Often found infesting dying trees or abandoned logs.

Powder Post Beetle

Appearance

  • Adult beetle is flattened and elongated with 1–7 mm in length. 
  • Reddish to dark brown in colour. 
  • Larva is white in colour, slightly curved and can measure up to 5mm when fully developed. 
  • Newly hatched larva is straight, extremely slender and less than 1 mm long.

Life Cycle

  • Under favourable condition, it takes 9–12 months to fully develop. 
  • Adult lives 1–3 months.

มอดไม้
