Treating domestic kitchens: Harbourage areas

Check harbourages thoroughly

Cockroaches are thigmotactic pests, which means they prefer to hide in tight places where they have something touching either side of their body and there is the relative safety of only one entrance and exit. When treating the kitchen, some pest controllers can overlook critical hiding spots like a knife block or a food warmer tray – both ideal harbourage areas as they are in vicinity of food, warmth and water.
