Size: 1/32 to 1/4” Color: Reddish Brown to Black Powder Post Beetles will lay their eggs in exposed wood pores, cracks or crevices. They are active at night, readily fly and are attracted to light. The larvae will tunnel with the grain of the wood and cover the tunnels with fine powder like dust/frass that often will fall from the hole. They like both lumber (oak, hickory, ash and sometimes bamboo) and manufactured products.
Determination of infestation activity and severity will determine the treatment plan. Replacement of damaged lumber or full tarpaulin fumigation is recommended.
