A pest control system for bed bugs or similar crawling pests. The system includes at least one intercept wall extending generally perpendicularly to the plane on which the pests are traveling for directing the pests to interact with a trap or a treatment zone. The effect of the intercept wall may be enhanced by provision of at least one substantially smooth guide surface positioned adjacent the intercept wall. When pests come into contact with a smooth surface they experience difficulty in traversing it. This causes the bugs to cling to the more textured surface that they are already traversing. The intercept wall is preferably placed in the direct path of the transition line between the textured surface and the smoother guide surfaces and forces the pests to interact with an adjacent trap or treatment zone.
