Some bedbugs are better climbers than others, and the bloodsuckers’ climbing prowess has practical implications.
To detect and monitor bedbugs, people use an array of strategies, from DIY setups to dogs. Pitfall traps placed near the base of furniture are highly effective for detecting and monitoring an infestation. The traps, which rely on smooth inner walls to prevent escape, are sold around the world.
