![]() Certain design characteristics of cockroach sticky traps may be relevant not only for capturing bed bugs but also other crawling arthropod pests. Small modifications to sticky traps have been found to increase the catch rate of some arthropods, such as German cockroaches. Sticky traps have also been observed to catch ants, small flies, mice, beetles, and millipedes. Sticky traps, however, are proven effective monitors of cockroaches and spiders. Often, bed bugs are not the only pests encountered in homes, so a monitoring device that can catch multiple pests would be advantageous and cost-effective. ĭespite the success observed from using “interceptor” traps for bed bug monitoring, these traps are designed to catch only one pest species within the urban environment. This trap was not found to be as effective as “interceptor” trap designs at detecting bed bug activity. The line of adhesive and dots of adhesive can capture bed bugs trying to harbor in the trap. The central adhesive line is surrounded on each side by a row of adhesive dots. The Catchmaster BDS has a line of adhesive down the center of the trap. The closest trap design to a traditional sticky trap that has been evaluated has been the Catchmaster BDS (Bedbug Detection System, AP&G Co. In contrast, pitfall or “interceptor” trap designs were found to be more effective than even visual inspections at detecting low level infestations of bed bugs. A pest control industry survey conducted in 2005 found that 67.9% of pest control companies were using sticky traps as monitors for bed bug infestations however, former studies have shown that sticky traps were only marginally effective when used as bed bug monitors. (Hemiptera: Cimicidae), in the western world over a decade ago, a search for effective monitoring and control measures were sought after. With the resurgence of bed bugs, Cimex lectularius L. Sticky trap designs with smooth surfaces around an adhesive could be used to monitor not only bed bugs but also German cockroaches. This trap was not only able to capture bed bugs but was also able to detect unknown German cockroach, Blattela germanica, infestations. A sticky trap design with a smooth plastic film around the adhesive was tested in the field to see if it could capture bed bugs in apartments with known bed bug activity. ![]() Results of these assays showed that as the acetate surfaces got smoother (lower R a), bed bugs were more likely to get trapped in sticky trap adhesives but also less likely to travel across the smoother surfaces they encountered. The number of times the bed bugs contacted the R a treatment but did not cross onto the treatment was recorded. In the third assay, bed bugs were placed into circular acetate arenas where they were surrounded by different R a treatments. ![]() ![]() The second assay was set up similarly to the first assay except that the outer portion of the acetate disc had a different R a than the center. ![]() Each disc was surrounded by sticky trap adhesive and number of captured bed bugs were recorded. In the first assay, bed bugs were placed onto acetate paper discs with different roughness averages (R a). We examined how the surface roughness around the adhesive of a sticky trap affects both bed bug behavior and adhesive entrapment. Little evidence has been presented on the usefulness of sticky traps for monitoring bed bugs, Cimex lectularius. ![]()
