8 Terrifying Reasons Why Mice Are Dangerous Infographic

When considering whether or not mice are dangerous, your first thought is probably ‘yeh, they can carry diseases’. But that is not the only reason why you should fear them in your home.

Let’s take a look at the 8 reasons now.

1. Fire Hazards

Since mice have ever-growing incisors, they need to chew on items to stop them from over-growing. Once their incisors have grown to a certain length, feeding normally becomes a challenge for them. This explains why they are known to gnaw on materials such as cables and wood.

When mice are looking for a way into your home, they will chew through mortar walls and wooden beams in attics and walls.

Like other rodents, they will chew electric wires if they are in their way. Short circuits might be caused when they chew on the wires. I do not need to tell you how dangerous that can be!

The sparks that may come from damaged electric wires can land on clothes or other home items, and this can lead to a fire.

As a homeowner, it is vital to pay close attention to any of these signs to avoid fire hazards.

2. Infections

Staying healthy in the winter is a real challenge due to the prevalence of common cold and flu. Also, it is quite unfortunate that some people are not aware of the dangers posed by mice, especially during colder times of the year.

Mice invade many homes in the winter, and a single infestation might lead to some life-threatening infections such as hantavirus, bubonic plague, and salmonellosis. All of which are devastating to your health!

When it gets cold outside, mice start to look for warm, safe areas where they can also get food, which is usually homes. They use small cracks, crevices, and holes to enter homes.

Food contamination can also take place due to the accumulation of mouse poop that could spread bacteria.

3. Chew House Structure

Many animals can cause serious damage to your home. However, if left, mice are one of the most destructive pests that can invade your home.

Mice will use every possible opportunity to invade and cause serious damage to the property. Other than causing infections and dropping their feces everywhere, mice can damage your home by chewing vital structural elements of your home.

Other than chewing wires and wooden materials, soft furnishings, and electronics in your home, they can access your closet and chew your clothes, and other items.

4. Carry Fleas

Mice have a close connection with fleas, which is why you don’t want to have them in your home.

If you have pets like a cat or dog in your home, then you have probably encountered fleas at some point. Fleas are tiny, but they have strong legs that let the jump long distances. This makes them a real nuisance.

Flea bites are not good for your skin. Not only are they irritating, but they could also cause some skin infections.

Fleas are known to carry parasites such as tapeworms. The fact that mice could spread fleas in your house makes them horrifying, and bad for your health. Mice are likely to be infested with fleas which will cause a similar infestation in your house.

5. Bite You

Mice can bite you. Although this is not the biggest mouse danger, it might hurt!

This is probably not something you wanted to hear! But they can, and they will if they are particularly aggressive and you have backed them into a corner.

Mouse bites are not particularly painful, but they can be a shock if you are not expecting it!

6. Carry Ticks

As small as a mouse is, it can be host to a number of different bugs! We have discussed fleas above, and they are bad enough. Now we are going to discuss ticks.

Ticks are tiny insects that latch onto their host by burying their head under the skin. They tap into the blood flow and live the good life courtesy of you, or whoever they have latched onto.

Mice can carry ticks, ticks can get onto you, and ticks can carry Lyme disease.

Lymes disease, if untreated, can lead to very serious medical complications.

7. Mice Are Expensive

Cleaning up your home and fixing anything that may have been damaged by this rodent can be very expensive indeed.

This rodent can cause serious damage in a matter of days. Since you love your house and the contents, you will spend lots of money to fix the damage.

Once your home is infested, a lot of effort is required to ensure that you and your property are safe once again.

8. Hard to Control

In the winter, mice look for shelter, good, and safety, which they can only find in your home. However, you can always prevent them from entering your home by performing regular inspections.

Start by checking any signs of chewed mortars and wood around your house. You should also block all the holes, cracks, and crevices that they might use to come in.

Note that prevention is better than a cure. They can create nests in a matter of days. In each nest, you can find between five and twelve babies! It is better to stop them from coming in, right?
