The Times Union is reporting state officials are asking swimming pool owners to be on the look out for a tree-killing invasive beetle when they clean their pool filters. The Department of Environmental Conservation is conducting its annual Asian long-horned beetle swimming pool survey through Aug. 30. This is the time of year when the insects are active outside of the trees they are infesting. Volunteers are asked to check pool filters and skimmers and submit pictures of suspected Asian long-horned beetles to the DEC. The invasive species has killed hundreds of thousands of trees nationwide, including maple trees in New York City and on Long Island. More information and photos of the beetles are available on the DEC's ALB page at DEC [dot] NY [dot] gov. Read the full story in the Times Union.
