The effect of baiting refuge habitats around irrigated soybeans with bromadiolone was investigated for the control house mice (Mus domesticus) and to reduce their invasion of crops. Generalised linear models were constructed and used to predict changes in mouse abundance over time in both refuge and crop habitats of treated and untreated plots. Compared with untreated plots, bromadiolone significantly reduced the number of mice inhabiting the refuge habitat and reduced the rate at which mice invaded and colonised the adjacent crops. Despite this, no significant reductions in damage were detected as mice numbers failed to reach critical densities for crop damage on the untreated plots. This indicates a need for short-term predictive models when considering control strategies.
