PORTSMOUTH, N.H. — Newly migrated stink bugs used to packing themselves into Chinese cliffs are set to begin massing on Portsmouth buildings this weekend.
New Hampshire entomologist Alan Eaton told the Portsmouth Herald (http://bit.ly/2d8JtIE ) that brown marmorated stink bugs likely landed in Portsmouth by stowing away on vehicles shipped overseas in containers.
Eaton said after flying around during the spring and summer, stink bugs like to start looking for walls they can hide inside all winter.
But Eaton said the bugs aren’t harmful, and advised for homeowners to seal their walls rather than use pesticides.
The entomologist said his mapping data shows stink bugs now in 25 New Hampshire towns, most on the Seacoast.
