Some 370 Asian Longhorned Beetle traps are being strategically placed in the lower canopy of selected trees around Westborough, Shrewsbury, Northborough, Marlborough, Sterling, West Boylston and Clinton, state Department of Conservation and Recreation spokesman Julie Coop said.
These traps are black and about four-feet long with a white collection cup at the base. They are baited with a cocktail to lure that beetle.
"This cocktail combination has been proven to be effective at attracting the Beetle if it is in the area," Coop said.
"In prior years, these traps have been effective in identifying previously unknown areas of infestation."
These traps were placed earlier this month and will remain until September, with authorities checking them bi-weekly.
The DCR has been working with the USDA – APHIS to eradicate this invasive pest. For more information, contact the ALB Eradication Program office at 866-702-9938.
