This will get the mice that are resistant to a particular formulation and those that have become bait-shy. Bait stations can increase the effectiveness and safety of rodenticides. A bait station is any device that keeps children and pets from the rodenticide, but allows mice easy access. Place these along walls because these are the main places mice travel. Both store-bought and homemade bait stations can work well.
Mice occupy small areas.
Their daily movements are often within an area 10 feet or less in diameter. 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.
