Pool Owners Sought to Monitor for ALB

Adult ALB are active from late July through September. If they are in your neighborhood, it's possible one will end up in your pool! The more "eyes" we have looking for infestations, the better chance we have of finding new ones early and eliminating them. YOU are the key to keeping our forests free of ALB!

How to Check Your Pool for ALB

Inspect your filter. From late July until you close your pool, look at the debris you collect in your pool filter or skimmer.

Look for ALB. ALB is in the Family Cerambycidae, the longhorned beetles. Use the visual aids in the Pool Survey Guide (PDF) to help you know what to look for.

Take a photo. Photograph any insect you think might be ALB. The photo needs to include a good view of the insect's back.

Send the photo to DEC. There are two ways you can send photos. Please include your name and address.

  • Email: Send an email to with the subject heading "ALB Pool Survey".
  • Mail: Send a printed image to the Forest Health Diagnostic Lab at 108 Game Farm Road, Delmar, NY 12054.

Save the insect. Freeze the insect in a plastic bag or Tupperware container until you hear back from us.

No Pool? No Problem!

You can still help! Look for the telltale signs of ALB damage on your trees, such as exit holes, accumulation of coarse sawdust, pits in the bark, and oozing sap. See our Asian longhorned beetle webpage for photos of these signs, and contact DEC if you notice any in trees near you.
