Study Shows IPM and Baits More Effective Than Baits Alone
At 29 weeks of study, only one apartment in the IPM group had a high level of cockroach infestation. In contrast, the apartments in the bait treatment group had high level infestations at 29 weeks based on overnight trapping counts. The authors conclude that IPM is a more sustainable method of population reduction. Sanitation levels in the IPM group significantly improved at week 29, compared with that at the beginning of the study. The sanitation levels in the bait treatment group remained similar throughout the experiment.
The authors conclude, “We expect that IPM will provide better control at similar cost compared with bait treatment beyond 29 week.” However, the study finds that the front end costs associated with the IPM program are greater, with median costs per apartment during the 29 weeks at $64.8 for IPM and $35.0 for bait treatment only. The median amount of bait used per apartment in the IPM and bait treatment was 45.0 and 50.0 g, respectively.
