What Interceptors Do
Interceptors are shallow cups placed under the legs of beds and furniture. Bed bugs traveling to or from the bed fall into the textured wells and can’t climb out, so you get a clear, passive record of activity. They turn detection into a simple weekly glance.
What to Look For
Good interceptors have a steep, slippery inner well, a textured outer surface bugs can grip to climb in, durable construction, and a low profile that fits under most furniture. Larger outer rims also help catch bugs approaching from the floor.
Plastic vs. Other Materials
Most quality interceptors are rigid plastic for durability and easy cleaning. Some people add a light coating of talc-free powder to improve slipperiness, though many modern designs don’t need it. Browse bed bug interceptors on Amazon.
Pair With a Detector or Monitor
Active monitors and detectors can complement interceptors, especially in higher-risk situations. Explore bed bug monitors on Amazon to compare options.
Placement Tips
Place one interceptor under each bed leg and under nearby furniture legs. Make sure the bed doesn’t touch the wall and that bedding doesn’t drape to the floor — otherwise bugs can bypass the interceptors entirely.
Maintenance
Check interceptors weekly and clean them every few weeks. They’re reusable for a long time, making them one of the best-value tools in any prevention kit.
The Bottom Line
Interceptors are a low-cost, high-value foundation for calm, ongoing monitoring. Combined with a mattress encasement and a good flashlight, they form a reliable early-detection system.
