So the best place for bait stations is between the shelter and food source. When that's not possible, place the station along a wall near mouse activi ty. Trapping mice also works, but requires more labor than baiting. With traps you avoid the danger of rodenticides and the odor problem of decomposing bodies. You can get many trap types.
Snap traps are simple, inexpensive and effective.
Some of the newer snap traps have increased the size of the trigger mechanism. But you can expand the trigger mechanism of other traps with screen wire, cardboard, plastic or metal. Where you place traps is more important than what type of bait you use. Place traps along walls in the area of mouse activity. Use them singly or in pairs, perpendicular to the all, with the trigger end next to the wall.
