Selecting the right bait is important, especially where a plentiful supply of good feed is available, as in poultry houses. Also, the Norway and roof rats and the mouse each have bait preferences. Therefore, it is important to know which of these rodents you plan to poison so you can choose the right bait material. Children, pets and livestock must not have access to the bait traps or the dead rodents. They also like the juices of prunes and pineapple.
House mice are nibblers and like to try new foods.
Using baits different from the usual food source often works well on mice, with two or three choices of baits in small amounts, instead of using more of one bait. The roof rat is a finicky eater, wary of everything new in its environment, including food, and does not readily accept meat or fish. The roof rat likes cereal grains, chopped apples, sweetpotatoes, melons, prunes, pineapple, cookies, doughnuts, sweet chocolate candy, peanut butter, and tomatoes. Norway Rat Norway rats readily accept fresh meat and fish. They usually prefer a bait higher in protein and fat than their normal diets.
