To prevent full-blown mice in walls infestations, ensure you can locate their potential entry points. Do a little detective work using a flashlight before you set up mousetraps. 

Ensure you thoroughly check out your home, both low and high places. According to the National Pest Management Association, it is vital to figure out their entry point for the traps to be effective.

Here are a few other places you should check before setting up the trap inside and outside your home.

Set Your Traps to Get Rid of Mice in Walls

To get rid of mice in walls causing havoc in your home, you should consider using mousetraps. Find the most vulnerable spaces in your home and set the mousetrap there, for instance, along walls, on kitchen cabinets, or behind trash cans. 

Mousetraps come in a wide variety that you can choose from, ranging from design, cost, and function. Here are some of the mouse traps that you can consider using:

  • Live catch traps- Just like the mammal traps, these traps only bait the mice without killing. Once the rodent is in a cage, the trigger-activated door will only reopen after releasing the mice. 
  • Electric traps are also effective mouse trap that lures the rodent into a chamber before releasing fatal shocks. The interesting fact about this mousetrap, it can only shock pests but not pets or humans. 
  • Snap traps- One of the most common types of mouse traps that attract mice in their tracks. If used correctly, it’s easy to wipe out the entire mice population since they are fast and efficient. Clam, bar and hidden kill are types of snap traps. 
  • Sticky traps- Compared to other mouse traps, this is the least efficient since you can only use it once. Unlike the other high-tech options, once the mice get stuck on the adhesive glue board, you have to kill or set them free. 

Remember to use bait in all traps apart from the sticky traps. Most people prefer using peanut butter, but birdseed, chocolate, cheese, or nuts are effective for luring mice into a trap. 

Clear Out the Garage

Are you trying to mouse-proof your garage? The first step is to determine what is inside your garage.

Mice get attracted easily to dog food or birdseed. So if you’re storing this inside your garage, mice will easily invade your garage space.

There is less food during winter making rodents move into your homes in search of meals. Use strong, airtight plastic containers to store in your pet food and birdseed. These containers help reduce the food aroma that attracts mice making it difficult for them to invade your garage.

Besides, it’s vital to inspect your garage perimeter wall for cracks or crannies that can lead mice to slip through. Ensure you seal any tiny openings visible to your eyes, making it difficult for the mice to pass through.

Cats can be overwhelming and demanding. If you cannot keep up with their needs, you should consider revisiting the above-proven methods to eliminate unwanted house guests.

It can be overwhelming and demanding dealing with rodents, especially if they keep returning after doing so much to get rid of them. 

Instead of using dozens of snap traps, you can seek professional help from expert exterminators. Friends, neighbors, or family members can direct you to a professional who can help you with them.
