  • Using Rodenticides

Method 1: Mouse Trapping

When to apply this method: If the mice population is small enough, the mouse trapping method may yield fast results if you can do it properly. Of course, this method has some advantages over baiting or rodenticides. It’s an alternative way for those who feel bad when they use rodenticides.

To eradicate the mouse by using mouse traps, follow the steps below.

Step 1: Inspection

  • Inspect your whole house and attic.

It will never be possible to 100% get rid of mice permanently until you figure out how they enter your house and attic. A dime or a quarter of an inch size hole is enough for mice to enter your home.

So, the first thing you should do is- check out how mice are getting inside your home as well as the attic. Mice enter in the vents, gaps in siding, and area where pipes and wires go into the house. And then they creep up into the ceiling and attic. Also, look for any holes or open gaps in the rooflines.

  • Pay tremendous attention to detail

Discover the possible entry points you need to pay immense attention to detail. So, look for signs of mice in the attic, for example, urine, mouse droppings, chewed item, etc. A black-light is helpful to look for these signs.

Step 2: Execution

  • Seal all the entry points of mice.

Making your home rodent or mice-proof is an effective way to stop the infestation of this nuisance. Eliminate each entry point- holes and openings.

  • To seal small holes or gap: you may use caulk and steel wool scouring pads.
  • To seal bigger holes/ openings: Sheet metal, concrete mortar or heavy hardware cloth are good option to patch the larger openings.

– Avoid wood, plastic, or other materials that mice can chew easily to seal the holes or gaps.
– Make sure doors, windows, and screens fit tightly. To keep the mice out of your home, around loose-fitting doors use weatherproofing strips.
– If you fail to seal your home and attic properly and block off the mice entryways, mice may return in the future and find their way into your home. If it happens, you’ve to start all steps over again.

Step 3: Trapping

So, you’ve sealed every opening and hole?


Now it’s time to proceed to trap and kill the mice that are already in your attic. Mice are easy to trap. And setting a mousetrap is an inexpensive way. Avoid cheese as bait. Instead, use bacon, peanut butter, or chocolate as bait.

Different types of mice traps are:

  • Snap/ spring trap
  • Electric trap
  • Glue trap
  • Live catch trap/ live trap

Set mouse trap on the mouse runways or mouse trails in the attic. If they are high in numbers in your attic, you can use a lot of snap traps or a repeating trap. Follow this step until you hear no more sounds in the attic.

If you don’t want to use the sticky traps or kill the mice and go through the filthy cleanup process, you can use a live catch trap.

What is a live-catch trap?

In a live catch trap, the mouse gets trapped inside it. After they get trapped, you can release them into the wild.

You must wear a dust filter mask or respirator and rubber gloves when handling the dead mouse body. Otherwise, you may come in contact with a disease organism.

Step 4: Cleanup and Sanitization

Don’t forget to check the trap regularly. Dispose of the mouse bodies regularly and replace the new bait. Also, clean up all the droppings found in the attic. These are necessary to get rid of pathogens, germs, and odors that may attract new mice. Cleaning up roof gutter & the attic space will help you prevent the growth of mold that happens with the mouse feces and urine.

Disadvantages of trapping

This method requires disposing of the dead mice’s bodies before their odor becomes a problem in an inaccessible area.

Method 2: Applying Rodenticide or Mouse Block

Rodenticide is toxic baits that are available in meals, pellets, and block forms. These are toxic to a pet, human, and other wildlife. So, you should use these in the areas where children and pets can’t access them.

When to apply this method:

If the numbers of the mouse are high, using rodenticide is a quick way to get rid of it.

Follow the steps below:

Step 1: Set the baits approximately 15 to 50 ft. apart. If the infestation is heavy, place the bait closer to 15 ft.

Step 2: To protect against accidental poisoning, you’re recommended to tamper-resistant commercial rat bait stations that can hold the toxic baits in place and keep pets and children out. And it’s also a national guideline and law while using rodenticides. Try to use the best bait stations. 

Step 3: Refill the bait station more often.

Disadvantages of Applying Rodenticides

It’s not wise to use mice or rat baits that contain rodenticide without trapping them. The reason is the bad smell of dead mice may be a problem in the attic.  

Avoid using poison for mouse control. Mice poison won’t kill all the mice. The mice that die by poison will rot in your house, attic, or any hidden area and will create a mess.
