How Do You Know When All the Mice Are Gone? What to look out for?

To dispose of the mice in your house, you should realize that they’d invaded your home in the first place. Of course, it might not be as easy as it seems to be. They’re nocturnal creatures that roam around your house cautiously. So if you don’t actually see one, it might take time before you become aware of the problem you’re facing.


However, even if you might not see, smell, or hear the rodents when they’re already there, the droppings they leave behind, or the holes they make will give away an infestation. Therefore, if you notice signs of mice activity, take matters into your hands before the damage is done. But then, a question pops in your head –  How do you know when all the mice are gone? After reading this article, you certainly will.



Mice Won’t Disappear by Themselves!

Once you’re dealing with mice infestation, it’s up to you whether they’ll be gone for good, or will remain inside the house and call your home theirs. But, the latter one isn’t really an option, is it? Therefore, a cat can be a good alternative against these uninvited guests, however, the best and most efficient option is a mouse trap (if you decide to deal with the problem on your own.) However, you don’t have to kill the rodent, you know. Not all the traps are deadly, but you can find humane as well. Otherwise, if it’s too unpleasing for you to remove the pests by yourself, call a professional to get the job done.


Put Flour on the Floor Around the Bait

Once you’re sure the rodents have invaded your home, to determine the level of infestation, their size, and the actual place where they reside, try the flour test.

Firstly, place some bait, such as peanuts or oats, overnight on the floor in areas where you suspect mice activity, usually in the dark, warm places, or near food sources. Then, spread some flour around it. They’ll be tempted to come to the bait, and they’ll leave tracks of their footprints on the dusty surface. If they’re around  ½ centimeter in size, and look like little dots, it’s mice infestation you’re dealing with. Footprints twice as big than that indicate that it’s rats that have invaded your home.


Does ONE Mouse Mean an Infestation?

One mouse certainly doesn’t mean an infestation. But, this isn’t Tom & Jerry, where only one tiny, cute mouse lives inside the hole and only bothers the cat. If one is already there, you can be sure that there are more! Or will be. And they won’t cause problems to the cat, but to you.

Once the mouse finds a way inside your house, the others will get there, too. What’s more, they multiply like crazy, so they can go from being unnoticeable to causing a total infestation at warp speed. So, if you notice any signs, act immediately, before it’s too late.


Threats of Mice Infestation

The rodents, such as mice and rats, are in constant search for food and shelter, all of which they can find in your home, so it becomes their new residence. Although they might look like little, harmless creatures, the pests can become a real threat to both your health and property. Imagine going up into the attic and the first thing that comes to you is the odor of the rodent urine. Or, mice droppings in your kitchen, which certainly isn’t a sight you want to see.


But, it’s not just an unpleasing sight and smells the critters expose you to. Once they get inside the house, they bring thousands of dangers with them. For instance, your house is at risk of fire caused by the rodents gnawing through electrical cables. Also, they’ll chew anything that might be useful in building their nests. They’ll even build the nests in any place they find suitable for them to reside.


Health Risks Posed By Mice and Rat Infestations

Speaking of diseases and viruses the rodents spread, take a look at the following list of just a few of them.


  • Bubonic Plague – Caused by a bite of an infected rodent flea, which kills the rodents and continues its search for blood from other sources. Either people or animals that find themselves in places where the rodents have recently died from plague are at risk to get bitten by the plague-infected fleas. The bites can cause fever, painfully swollen lymph nodes, or headache.
  • Hantavirus – Bank voles, white-footed deer mouse, and the yellow-necked mouse are the reservoir for this deadly virus. A person becomes infected by being exposed to or inhaling virus-contaminated rodent urine, feces, or saliva. The best way to prevent infection is by minimizing contact with rodents since there isn’t curative treatment.
  • Salmonellosis – A type of food poisoning, which is spread through the consumption of food and water contaminated with infected rodent excreta. Diarrhea, fever, and abdominal pain are just some of the symptoms of Salmonellosis. 
  • Rat-Bite Fever – It’s an infectious disease, which, if not treated right, can be fatal. People can get infected by being in contact with infected rodents, or consuming food contaminated with urine and feces of the rodents that carry the bacteria. Some of the symptoms include fever, vomiting, muscle pain, or headache.


So, how do you know when all the mice are gone? Well, if you don’t notice any signs of mice activity after you’ve taken all the necessary measures to get rid of them, they’re most certainly gone. If you’re not sure whether the war is finally over once and for all, go with the bait and flour once again. Also, check for nests in any place the rodents would hide. If you’re still not sure, call a professional that will have your home thoroughly examined.


Finally, to prevent the rodents from invading your house all over again, make sure you seal all the holes and cracks around your house, however small they might seem. Even the slightest opening can be a potential entrance for these critters, which are constantly looking for a warm place and food. Sanitize the entire house to make sure it’s free from all the debris. Keep the food in airtight gnaw-proof containers. Even now, you can be sure that you’ll keep the pests at bay.


Mice Infestation FAQs

Can Mice just Disappear?

Without you doing anything, once they get inside, the mice won’t disappear by themselves for sure. Their population will grow even more instead, and you’ll be dealing with a full-blown infestation in a blink of an eye. That’s why you should take some steps to dispose of these annoying creatures, such as:

  • use mouse traps
  • seal up all the cracks and holes around the house
  • sanitize your house
  • get a cat
  • keep the food in airtight containers
How many mice is considered an Infestation?

One mouse or two, which accidentally have gotten into your house in search of food, can’t be considered an infestation. However, if there are mice that have built a nest inside, now that’s a bit of a problem. Once they find shelter, they’ll start breeding very quickly, which can be considered an actual infestation.

What Scents Do Mice Hate?

If you don’t feel very comfortable killing or capturing the pests, you can prevent them from getting inside your house in the first place. Some strong smells can be an effective way to keep them at bay. There are scents the mice simply can’t stand, so once you spread them around your place, they won’t be tempted to get inside. Some of them are:

  • peppermint
  • ammonia
  • mothballs
  • cayenne pepper
  • Terminix
