DURHAM, N.H. – UNH Cooperative Extension is asking New Hampshire residents with swimming pools to check their filters regularly for Asian longhorned beetle (ALB). This invasive insect poses a serious threat to New Hampshire’s forests and trees.
While ALB isn't in New Hampshire yet, Karen Bennett, Extension forestry specialist, said, “We need many people looking for it so we can take steps to limit its spread, if it arrives.”
ALB was found in trees in Worcester, Mass. in 2008, but experts estimate it inhabited the trees for about 10 years before they identified the problem. Some Worcester homeowners subsequently reported that they had been collecting ALB in their swimming pools for years prior to the 2008 identification.
