Cockroaches prefer warm, humid environments and often hide in dark places such as cracks and crevices around sinks, cupboards, baseboards, behind dishwashers and refrigerators, under furniture, and inside walls.
Sealing off any potential cockroach entry points is essential in preventing an infestation. Carefully inspect the outside of the home or business and paying close attention to small crevices and cracks around windows, doors, and other openings.
Particular attention should be paid to potential nesting areas when placing bait or traps around your house. These could include dark corners of the basement or attic, tucked away cupboards, or even behind large pieces of furniture.
