German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Clarkfield's a humid continental climate with brief, warm summers and long, brutally cold winters, more severe than the Twin Cities the farther north you go keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms.

Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.
