Asian Longhorned Beetle (ALB) - Pool Survey

If you own a pool, look for ALB
in your pool filters.

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" 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, 437 KB) to help you know what to look for.

Take a photo. Photograph any insect you think might be ALB. We need a good view of the insect's back, as shown to the right.

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

  • Email. Send an email to with the subject heading "ALB Pool Survey".
  • Text. Text an image to (518) 810-1609, and type "ALB Pool Survey" in the body of the text.
  • Mail. Send a printed image to the Forest Health Diagnostic Lab at 108 Game Farm Rd., 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.
