Garages are likely to attract field mice. And here are the steps you can take to prevent them:

  1. Set a Trap

Some prefer humane methods of trapping mice because they don’t like killing them.

In my opinion, instant kill is also a humane way to get rid of mice. If a mouse trap can provide clean kill that minimizes the animal’s trauma and suffering, then why not?

Other humane methods include:

  • Not keeping food in their reach
  • Not keeping the trash can open indoors
  • Employing ammonia and peppermint

There are different types of mouse traps, anyone can be used to get effective results:

Electric Mouse Traps

These quick-catchers need to be several in order to see success. Using 3 or more of these strategically can turn out really effective. And because you can use them over and over, they’re cost effective as well.

TIP: If you are using only one, then don’t delay to empty the trap between kills. However, using only one trap slashes down your chances of getting rid of them for good.

Here’s how these traps work:

  1. You open the lid and set the bait
  2. As the bait is at the back of the trap, mice must enter the trap
  3. Once the sensor senses the presence, it emits a huge electricity and kills it
  4. You open the lid and trash the mouse
  5. Rinse and repeat

Plastic Snap Traps

These are made of solid, long-lasting plastic, which is reusable. It has a small cup for the bait – perfect for a small piece of peanut butter.

Here’s how these work:

  • Place a bait
  • You pull back the lever exactly 90 degrees
  • After the mouse hits the plate, the lever is released and the mouse is caught

Plastic Enclosed Snap Traps

These are effective and safe for using around your pets and kids. The success depends on you setting the bait right. The trigger isn’t much sensitive like other models. So if you’ve really small mice, they sometimes steal the bait without being captured.

Here’s how they work:

  • You bait the trap
  • You press the lever or turn it open until it makes the ‘tick’ sound
  • The mouse enters, the sensor senses, and bam, the mouse is caught
  • You trash the mouse (don’t forget about precautions)

Catch and Release Mouse Traps

As the name suggests, these traps are for capturing the mouse and then releasing them. There are 2 types of such traps – Plastic Tubes and Metal Cages – it’s up to you, both work the same.

Here’s how they work:

  • You bait the trap
  • Then you set the trap up and make sure the door is open
  • Once the mouse enters, the trigger closes the door
  • The mice get trapped

These are geared towards people who can’t stand killing these creatures.
