The most feared “vermin” are rats and snakes. The vegetation in a natural landscape does not provide the type or quantity of food required to sustain a population of black or Norway rats. These nonnative rats do not eat the seeds of our native grasses and flowers. Rats are more likely attracted to human-produced food (corn, grain, pet foods, food scraps) provided in and near structures like barns or garbage dumps. A neglected lot with human-deposited food litter among the untended growth is indeed a rat magnet, but the managed natural landscape is not.
