Placement Bait and trap stations should be placed near burrows, harbourage or in areas where the rats and mice normally travel. They have a habit of running along the skirting boards. Bait and trap stations should be placed near these. Traps and baits are best placed behind objects, in dark corners and under shelter, because rats and mice will avoid open spaces. Rats are generally wary of new objects in their surroundings, so you will need to have the traps or bait stations in place for sufficient time that the rats become accustomed to them.
Mice are the opposite, and are quite inquisitive of new objects.
Failure to control rats and mice may also be due to too few bait stations with large distances between them. Mice in particular, but also rats, generally do not move large distances. Bait stations must be inspected and replenished regularly to ensure that sufficient bait is always available. Baiting must be continued until no more bait is taken. For safety reasons all baits should be placed under a protective cover.
