Mice and Light Subject: Are Mice Nocturnal?

While finding the signs of mice living in your home is pretty simple, capturing mice is a whole problem altogether. The worst part of it all is that it’s only a matter of time before they reproduce, and the amount of mouse droppings in your house begins to triple.

So what exactly is the best way to get rid of them? And what time, between night and day, is best for you to go searching?

Are Mice Nocturnal?

Yes. The reason you hardly see mice is because they are mainly nocturnal or crepuscular animals. That means that they only operate in darker environments. 

Although mice are more active in dark and dusk, they also rely on their environment to determine their activities. Their low position on the food chain forces them only to be active when there is minimal danger. 

Does Light Affect Mice?

Well, light has no direct impact on mice. Mice only avoid light as a defense mechanism in a bid to hide from predators or any impending danger.

This is why most mice that live outdoors will move around at night rather than during the day. 

For the mice within your home, they will only come into action long after your home is silent and dark. Mice will interpret the movement and darkness in your home as safety. As soon as they sense any movement in a room, they will then scamper to safety.

Can Mice See at Night?

Generally, mice have very poor eyesight, both during the day and at night. However, you should know that they are susceptible to bright light, and as a result, a nocturnal lifestyle suits them much better. 

Although mice have poor eyesight, they make up for their lack of sight by using their other senses. Their sense of touch, for instance, is very exceptional. Mice use their whiskers to move around and tell the difference in surfaces. What’s more, their whiskers help them in sensing a change of environment.

Mice also use their sense of smell to keep them within familiar territory. They start by marking their home territory with their urine. They then smell around the place to ensure that they are within range and that the area is undisturbed. So each time you place your trap here, the mice know it already!

Mice hearing is far better than their eyesight. They can tell any sounds their predators make, and this helps them to keep safe. They also use their hearing to communicate with each other.

Through the little squeaks they make, a mouse can communicate with other mice within your home. 

When Do Mice Sleep?

Indoor mice often sleep during the day. Studies show that mice sleep for up to 14 hours daily. This makes it much harder for you to capture them during the daytime.

So if you want to catch the mice foraging around your home, your best shot is to try capturing them at night. However, you should set your traps in the morning.

What Mice Do At Night?

Since mice spend most of their daytime sleeping in safer places, they get out at night to forage for food.

They are most active at night and will even form their nests and mark their territories in the depth of the night.

Nighttime proves more effective for their activities and keeps them safe from any lurking predators.

Where Do Mice Sleep?

After they find a comfortable and safe hiding place in your home, mice will then mark this base and begin nesting in that place. They will use tiny bits of materials from around your house and create a nest for themselves in your home. 

As a general rule, mice will stay in their nests for the entire duration of the day. However, in case their nest is disturbed or infested, you may see a mouse or two crawling around your house in the middle of the day. In such instances, the mice infestation in your home is significant.

To make their nests, mice will use their teeth to tear off bits of your blankets, cushions, and pillows. They also prefer cluttered areas of the house where most of these things are available. 

Do Mice Live Alone?

Much as the thought of one mouse scares and appalls you, you should know that mice do not like to live alone. Mice are very social and great breeders as well. They can quickly multiply and get out of hand before you even know it. 

As soon as you notice the first signs, it will pay to start plans to get rid of them once and for all. Please do not wait until there are too many of them before you start looking for a solution. 

What are the Signs Of Mice in Your Home?

So you suspect there are mice in your home but do not know for sure. Here are some of the telltale signs of mice you should look for in your home.

  1. Gnaw Marks

Look out for gnaw marks in your house and food packages to tell if there is a mice infestation in your house. Fresher gnaw marks often point to a continuous infestation. You will notice them by their lighter color.

  1. Mice Urine

As we said earlier, mice mark their territories by urinating around your home and their nesting areas. So if you notice a strong smell in certain areas of your house, you should take a keen interest and investigate the cause.

Mouse pee has a strong, ammonia-like smell. The worst thing about mouse pee is that it lingers long after the infestation. However, with some effort, you can get rid of the odor

  1. Mice Droppings

The surest telltale sign of mice in your home is mice droppings. You will find these droppings in cabinets, food, sinks, and other hidden areas of your house. However, the nests and breeding places are where you will find most of the droppings.

Look out for fresh and damp droppings. The older, dry droppings look gray and crumble when you touch them. The more droppings you find in your home, the more intense your infestation is.

  1. Nests

If you find nests made of shredded fabric, paper, and dried plants, then you have just found a breeding and nesting point in your home. With the nest, you will likely find fresh droppings, tracks, and a smell from this place. If you do, then there is undoubtedly an infestation in your home.

  1. Mice Tracks

This is often the most challenging sign to spot. This is because mice tracks are often slightly lighter and will need you to hold a torch against them to see those faint lines.

Another alternative you may consider is using white flour or baby powder on the floor and watching for the tracks that they will leave as they crawl around. 

Keeping Mice Out of Your Home

Although they are tiny and seemingly harmless, mice can cause significant losses in your household. What’s more, they can carry diseases and infect you and your loved ones.

As such, you need to put in all the necessary measures to keep them out of your home. Here are some of the things you can try;

  1. Proper Food Storage

 A house without readily available food is not one that mice can thrive in. So you may want to store all your food in airtight containers for you to keep out the rodents. 

  1. Seal off All Entry Points

Scout your house for any holes or cracks in the walls that mice can use as entry points. Please do not ignore any holes or cracks, no matter how small they seem.

Mice can squeeze themselves through the smallest of places. Also, check your chimney and ensure that it does not make it easy for mice to get into your home.

  1. Well Ventilated Attic

Attics are often breeding places for mice and rats. It gets even worse if your attic is stuffy and poorly lit. If you want to avoid rat infestations, you will need to improve the lighting in your attic at all times.

You will also need to keep it organized and avoid overstacking it with unnecessary things. This way, ice will find it much harder to breed there, and you will prevent infestation.

  1. Repair all Leaks

Moist and stuffy places are the ideal breeding point for mice and other vermin. To be on the safe side, be sure to inspect your plumbing from time to time and repair any leaks that may lead to an accumulation in the moisture level around your house. This is often the first step to managing an infestation.

Contact the Professionals

When you encounter mice infestation in your home, your first impulse may be to manage it yourself. However, depending on the level of infestation, you may need the help of a professional exterminator. Remember, the best way to tell the extent of the infestation is by contacting a professional.
