Invasive Asian longhorned beetle is active from now through Labor Day. DEC is asking pool owners to check filters for the insect regularly and submit a report if any are found.
ALB attacks and kills maples, birches, willows, and other hardwoods. They emerge from infested trees in the late summer to find a new host. The beetles are 1.5 inches long, have long black-and-white antennae, and have black and white spots on their body.
They should not be confused with the native white-spotted pine sawyer, which has a distinctive white spot on their back, below their head.
No pool? You can still help. Be on the lookout for ALB exit holes, sawdust accumulating at the base of trees, oozing sap or pits in bark.
If found:
- Email photos to the Forest Health Program at foresthealth@dec.ny.gov; or
- mail insects to DEC’s Forest Health Diagnostics Lab for identification, Attn: Jessica Cancelliere, 108 Game Farm Road, Delmar, NY 12054.
