False Chinch Bug Migration

Nysius raphanus

Posted on: July 19, 2019 by Maria Held

The Caldwell Extension office has received multiple calls of masses of false chinch bugs. They may aggregate in large numbers on buildings or driveways especially if hosts are harvested or managed with herbicide. See the attached photo of a false chinch bug aggregation on a driveway.
Insecticides will have little, if any, effect for limiting this situation and are not recommended. False chinch bug migrations resulting in nuisance problems in buildings usually are of short duration and rarely last more than a week.
