Lyctids/Powderpost Beetles

Important Considerations:

• Lyctines are known as powderpost beetles due to their larvae producing a very fine, powder-like frass in their galleries
• Females tend to lay their eggs in exposed wood, cracks, or crevices
• Developmental time from egg to adult normally takes about 9 to 12 months
• Adults have short lifespans and live only 1 to 3 months
• These beetles attack sapwood and only types of hardwoods that are usually less than a decade old

Where to Find Them on Your Property?

You may find Powderpost beetles attacking oak wood, hickory, and ash, but they can also attack other native and tropical hardwoods. On occasion, they can also attack bamboo. Adults are most active at night and are attracted to light, which can factor into their attack. They will attack both lumber and manufactured products, so make sure to keep an eye on the wood that’s at your property.
