For a bed with suitable legs
Pitfall interceptors are usually the clearest starting format. Each furniture leg sits in a central well while bugs moving up or down must cross a textured outer wall and smooth trap channel.
- Measure every bed foot before ordering.
- Keep bedding clear of the floor and walls.
- Use the same type at each relevant leg.
For divan bases and awkward frames
When feet cannot sit inside a cup, use a passive or lure monitor close to likely harbourages. Placement and replacement intervals matter more than the number of marketing claims on the pack.
For low-cost supplementary checks
Sticky monitors can reveal some crawling insects, but bed bug detection evidence is mixed and trap design affects whether bugs approach and cross the adhesive. Do not treat an empty sticky trap as an all-clear.
The honest buying rule
Buy for a defined monitoring job. If an infestation is already confirmed, spend first on a competent inspection and treatment plan rather than accumulating uncoordinated gadgets.
