Asian Longhorned Beetle

Asian Longhorned Beetle ("ALB") is an invasive wood-boring pest that was discovered in Worcester, MA in August 2008 and in Boston in July 2010. ALB attacks maple, birch, elm, willow and other hardwoods, makingit a huge threat to the trees that grow in our parks and along every street. This pest also puts the livelihood of our state's forests as well as our nursery and maple syrup industries at risk.

ALB spreads through the transport of firewood or logs from infested areas. Once a tree is infested with ALB, there is no cure - it must be cut down.

Help protect your community from this invasive pest. Check trees for exit holes that are perfectly round and smooth, about 1⁄2 inch in diameter. In the summer, look for shiny black beetles, about 1 inch long, with bright white dots and long, banded antennae.
