Living with Snakes is a natural way of coping with mice -- outside. Poor Snakes get a bad press that's completely unjustified. (Mouse plagues can require different measures, unfortunatly.)

Every spring the sun on a sheltered doorstep at work brings out a brown snake or two to catch up on some heat; they get relocated out in the bush. In wheat areas west of here a single brown snake is worth its weight in gold if you take into consideration the number of mice one snake can eat and thus the potential number of mice (given their breeding rates) potentially removed from feasting on your wheat in the paddock.

But you don't really want them around the house.

The flies that get into my place are usually followed by a Cunningham's skink, which cleans them up but also leaves more evidence of its diet than geckos would. Around here it gets a bit cold for geckos during winter. Sometimes I also get invaded by an Antechinus or two so I have to use an Elliott trap to catch them so I can release them at least 5km away; they can individually control a huge amount of area so you have to remove them to a location they haven't already mapped.
