The top of the box is hinged to allow inspection of the bait. Some of the rodenticides may be purchased in a commercially manufactured bait station. Bait stations should be placed in areas of rodent activity. Placing the stations between the rodent's shelter and food supply will increase exposure and use. Bait stations should be placed next to walls, as rats and mice normally use these areas as travel lanes.
Traps are the best method of rodent control where poisons are unwanted or inadvisable.
Common snap traps, glue boards, and live traps may all be effective if rat numbers are low. For roof rats, the traps should be placed along beams, rafters, or other travel ways. For Norway rats and house mice, traps should he placed under cabinets or next to a wall. Summary Controlling rats and mice in buildings involves a combination of exclusion, sanitation, and wise use of rodenticides. Wherever possible, rodents should be excluded by blocking or sealing all areas where they may enter the building.
