All households in the two study areas constituted the target Toceranib for this study. To draw a representative sample, we used the list of street names as a sampling frame. We selected streets in each suburb using systematic random sampling to reduce the likelihood of sampling bias. All the streets in the two suburbs were first extracted from a comprehensive Brisbane street directory (69 streets in Graceville and 106 streets in Salisbury), listed in an alphabetical order. The sampling interval was calculated as follows: (1) the average number of household per street was calculated by dividing the total number of households by the total number of streets in each suburb; (2) the number of streets to be sampled was computed by dividing the target household sample size by the average number of households per street (69 streets in Graceville and 106 streets in Salisbury); and (3) the sampling interval was set to the total number of streets divided by the number of streets to be sampled (three in both suburbs). Survey questionnaires were delivered to households located on each selected street. To ensure the spatial representation of selected areas, our sample also included households located on streets herbivores either intersect or ![Toceranib]()
