Scientists are trying to keep this invasive beetle away from Vermont

Across six sites in Vermont’s forests, Savannah Ferreira and her team of trappers are on the lookout for six-legged invaders. If the rogues establish a stronghold here, they will pillage tree habitats and hold sugar producers hostage.

The trappers cloak lures in forest camouflage to spring on their would-be foe: the Asian long-horned beetle. Should the trappers prevail, the pest won’t establish a beachhead here. Fail, and the results would be ruinous.
