It’s time to check trees for invasive Asian longhorned beetle


August is a great time to enjoy the outdoors, and it’s also the best time to spot the invasive Asian longhorned beetle as adults emerge from trees. That’s why the U.S. Department of Agriculture is declaring August as “Tree Check Month.” Checking trees for the beetle and the damage it causes is one way you can protect trees and help the USDA’s efforts to eliminate this beetle from the United States.
The Michigan departments of Agriculture and Rural Development; Environment, Great Lakes, and Energy; and Natural Resources are joining the USDA in asking people to take just 10 minutes this month to check trees around homes for the beetle or any signs of damage.
The Asian longhorned beetle, or ALB for short, is a non-native wood-boring beetle considered invasive in North America because it attacks 12 types of hardwood trees, including maples, elms, horse chestnuts, birches and willows. Here, there are no predators or diseases to keep ALB populations in check. In its larval stage, the insect feeds inside tree trunks and branches during the colder months. The beetle creates tunnels as it feeds, and then it chews its way out as an adult in the warmer months.
Infested trees do not recover and eventually die. They also can become safety hazards since branches can drop and trees can fall, especially during storms.
