Effectively monitoring and controlling house mouse, Mus musculus domesticus, infestations in low-income multi-family dwellings

On-Demand
Student Competition On-Demand
This study was designed to better monitor house mouse (Mus musculus domesticus) infestations, study their spatial distribution in multi-family buildings, and evaluate the effectiveness of building-wide house mouse management programs.  Two low-income high rise buildings in New Jersey were selected for this study during 2019-2020.  Building-wide house mouse monitoring was initiated using bait stations with three different non-toxic baits.  Infestations were treated with two rodenticides over a 63 day period.  Effectiveness of the treatment programs were evaluated at 12 weeks, six months, and 12 months.  There were significant differences in the preference of non-toxic baits and the two toxic baits tested.  A newly studied bait, chocolate spread, was much more sensitive than the two commercial non-toxic baits.  Apartments located at lower three floors had significantly higher probably of being infested with house mouse. The house mouse management programs resulted in an average 87% reduction in the number of infested apartments after 3 months.  At 12 months, the number of house mouse infested apartments decreased by 94% in one building but increased by 26% in another building.  Sustainable control of house mouse infestations requires the use of an effective monitoring and control method and incorporating proper rodent-proofing measures.  Management programs should include an effective building wide and building specific monitoring system.
