Start with what you need to find out
No single trap wins for every home. The right choice depends on your bed, your room and your goal. A trap that suits a bed with open legs will not help with a divan base. So decide first what you want to learn, and then pick the format that can answer it.
Before you buy anything, check why you are worried, because a trap is not the only clue. If you have bites or marks and no proof, read our guide to the early signs of bed bugs. Looking for live bugs, shed skins and dark spots often tells you more than any trap.
For a bed with suitable legs
Pitfall interceptors are usually the clearest place to start because each bed leg sits in a central well. A bug that climbs up or down must cross a textured outer wall and then fall into a smooth channel. Our interceptor guide explains the design in more detail.
Fit matters here, because a cup that is too small will not hold the leg. First, measure each bed leg before you buy interceptors. Next, keep bedding off the floor and away from the walls. Otherwise bugs can bridge the gap and skip the trap altogether.
For divan bases and awkward frames
Some beds, however, have no feet that can sit in a cup. In that case, use a lure or passive monitor near likely hiding places, such as the bed base or a skirting board. Our page on active monitors shows how these differ from interceptors.
Placement and regular checks matter more than the claims on the box. For example, a monitor in a cupboard that you never open will tell you nothing. Therefore, pick a spot you can reach, and check it on the same day each week.
For low-cost extra checks
Sticky monitors can catch some crawling insects. However, the evidence for catching bed bugs is mixed, and the design affects whether bugs walk onto the glue. Use them as a back-up rather than your main tool. You can read more about their limits in our sticky trap guide.
An empty sticky trap is not an all-clear. Similarly, an empty interceptor only means no bug crossed it that week. Our page on what traps can and cannot do covers this in full.
When monitoring is not enough
A trap detects and monitors activity, yet it does not treat a home. If you have confirmed bugs, spend your money on a proper plan first. A professional bed bug inspection can confirm the species and show you how far the problem has spread.
After that, traps become useful again because you can use them to check that treatment has worked. Our how to use guide shows you where to put each type and how often to look.
The honest buying rule
Buy for one clear monitoring job. We do not give star ratings, scores or prices on this site, because we have not run lab tests and prices change daily. Instead, we compare the design, the fit and the limits of each format.
If a pack promises to cure or remove bed bugs, walk away. No trap can do that. In short, choose the monitor that fits your bed, place it well, and check it often.
