Bed Bug Traps
Trapping bed bugs as a sole method of control will typically not eliminate the population.
However, trapping in critical areas will reduce the chances of the bed bugs contacting humans.
Some traps are sticky traps and are used strictly for monitoring to see if bed bugs are present and in such a number that they become trapped. This indicates a population that must be controlled immediately. These are valuable to keep an eye on whether there is a population and in such numbers as to cause a concern.
There are also traps which are essentially cups filled with talc and are placed under the legs of the bed or frame. The bed bugs climb into the traps to gain access to the bed but cannot climb out of the trap and never reach the bed. Some similar traps can be filled with mineral oil. The value with these traps is that they not only monitor populations but they also prevent bed bugs from climbing into the bed.
There are several detection devices which use heat, carbon dioxide, a chemical attractant, or a combination of these. These devices are commercially available and have enjoyed popularity especially in commercial accounts; however, some are cost prohibitive for most homeowners.
University researchers are working to better understand the bed bug biology, habits, and control potential. This information should lead to more advanced traps and monitors and as a demand increases, supplies and improved manufacturing processes could lead to affordable pricing for most units.
