How to Kill Mice and Rats With No Smell

Updated November 21, 2016

Rodents enter your home in search of food. Once there, they pose a health threat because they carry germs, bacteria and diseases. If your home is invaded by mice or rats immediate treatment is necessary. Although rodent poisons are effective, they can die in your walls or attic and leave an odour. Luckily, you can use trigger traps to eliminate them and avoid unpleasant smells.

  1. Clean your home to make traps more effective. This removes their food source and potential shelters. Put food in airtight storage containers. Dispose of trash properly and remove it from your home as soon as possible.

  2. Place trigger traps around areas of high rodent traffic. Place the traps along walls in quiet out-of-the way areas. When placing the traps, keep the trap perpendicular to the wall with the trigger that holds the bait facing the wall. When using two traps in one place, put the traps parallel to the wall with the triggers that hold the bait facing away from one another and the swing arms together. Most rodents scurry along as close to the wall as possible. This placement helps increase the odds of catching and killing them. For mice, the traps should be 8 to 10 feet apart; for rats, 10 to 20 feet apart. The number of traps needed depends on the size of your home. For a small home, 10 traps should be efficient.

  3. Bait your traps based on the type of rodent you are trying to attract. Contrary to popular belief, the best bait for a mouse is not cheese. Instead, use peanut butter. For a rat, you can use dried fruits, bacon or nuts.

  4. Check your traps daily. Once a trap has been sprang by a rodent, the bar will snap back and trap the rodent. The force of the bar breaks the rodent's neck, killing it. When you find a dead mouse or rat you can pick up the trap and dispose of it in a dustbin, rodent and all.

  5. Tip

    When choosing a snap trap, choose the smaller sizes for mice and the larger sizes for rats. Trigger traps kill the rodents instantly making for a more humane death than glue traps, which kills the animal through dehydration and starvation. Poison traps are also slow acting. And with poison, the rodents are able to leave the baited area and can die in out of the way places, resulting in odours. Whenever you come in physical contact with rats and mice, either living or dead, always wear gloves to protect your hands from the germs and diseases they may be carrying.
