A stroll in the park. The backyard barbeque. Hiking in the woods. Dusting off the tree swing. Summer outdoor activities offer a prime opportunity to help protect the nation's hardwoods from a potentially landscape-altering pest, the Asian longhorned beetle (ALB).
Residents of Illinois, Massachusetts, Ohio, New Jersey and New York know all too well the devastation wrought by the ALB. More than 130,000 trees combined have been lost in these states due to this invasive pest.
August is a time of peak emergence for the Asian longhorned beetle, which was first discovered in the U.S. in 1996, likely arriving here unknowingly inside wood packing material from Asia. With no natural predators, it threatens recreational areas, forests, and suburban and urban shade trees. All states are at risk because the beetle attacks 12 genera of trees, including birch, maple and elm. If ALB were to become established in the United States, it could have a severe impact on the timber, maple syrup, tree nursery, and tourism industries, as well as the environment. In addition, public spaces, yards, and neighborhoods would take decades to recover.
The states that are currently fighting an ALB infestation (Massachusetts, New York and Ohio) and those states bordering an infestation are at a higher risk as the beetle can be unknowingly moved inside tree debris or firewood, thus starting an infestation in a new area. USDA officials caution that you buy and burn firewood at your destination and purchase it locally.
The ALB may look menacing, but it is harmless to people and pets. It can be seen on trees, branches, walls, outdoor furniture, cars, and sidewalks and caught in pool filters. With these unique characteristics, the beetle can be easy to see:
- 1 to 1 ½ inches in length
- Long antennae banded in black and white (longer than the insect's body)
- Shiny, jet black body with random white spots
- Six legs
- Legs may appear bluish in color
