Do mice bite?

Having pests at home in a nightmare for any homeowner or business owner. Especially when you deal with animals like rodents: rats and mice altogether. These animals are very dangerous for human beings as they can spread many diseases and contaminate food, furniture, and many other things.

Their lives consist of going around every corner of your house foraging for food or water and looking for a place to set up a nest where they can raise their breed. Always being in the way of humans, although, mice are really scared of us so they will try to avoid you whenever they can. It is not a pleasant view, so these infestations can bring more than a hazard for you and your pets.

But there is one question that many people ask when dealing with them at home: Do mice bite? Yes, they do. However, there is more to that than you need to know aside from their consequences and their occurrence.

When do mice bite?

To understand mice, you must know about their behaviour. First, in the winter months, they will look out for something warm, as they need warm places to nest and properly develop. They’re usually scared of humans, so for you to see them at home is hard, though it can happen. During those months you could encounter their presence, mostly at night.

Having said that, you need to know that they do not attack humans on purpose, they need to be triggered to do that. However, you must know that these cases barely happen all around. It is not common. On rare occasions, mice will bite if they are sick or disoriented. Whenever they feel like that, their survival instinct triggers and tend to defend themselves in any way possible, and that is one of their ways. Sometimes people poison them and as they feel ill, they start to lose consciousness and feel threatened.

If you find a mouse and you corner it, you might be in danger of getting a bite. They get extremely angry and attack at any sudden movement. If you try to move it or do something to it, it will retaliate and bite back. Do not contact them when you see them as this can happen.  Mice need to be treated delicately because any response from you is going to affect them.

Another way of having these animals bite you are, even though it is very rare, is leaving crumbs on your fingers and if one of them hasn’t found food around, they will bite you. However, this is worst case scenario as most of the times they look for something else.

How does a mice bite look like?

The moment a mouse bites you, it will certainly start to feel like you’re burning. It is a terrible sensation, as if you had cut through your skin with a knife, this is due to their sharp teeth. Blood can be seen after this has occurred.

You should thoroughly clean the wound with peroxide, warm water, or soap, as this kills any bacteria in the area where you were bitten. It is recommended to try and push a little bit of blood from the wound, so it takes out any object or solid left inside the injury. Dry it and protect it with a bandage. Take ibuprofen or paracetamol if you feel discomfort or pain from the wound.

Are mice bites dangerous to humans?

Answering the question do mice bite? We have stablished that they can do it, but, when this happens it is time to take some measurements and see why you should be worried.

If after the bite the swelling starts getting worse around the area, or if you develop a fever out of nowhere then you could have an infection and need of medical assistance.


Although not many cases have been reported around the world, Hantavirus is a disease that has a mild mortality rate (38%), and it is spread by mice through their saliva, urine, and faeces. It starts from having flu like symptoms and turns into a severe disease with shortness of breath, fluid in lungs and more. Do not hesitate in going to the doctor if you have one symptom.

Tick related diseases

Mice are the type of animals that don’t take showers too often and are usually infected by fleas, which allows more diseases to spread since they may be contaminated.

How long do flies live?

One of the common pests around the world are flies. You can see them roaming around your rubbish or any crumbs you may have left on the countertop, being on the TV or flying above you and sometimes like to land on your face. These insects are unwelcomed and considered to be disgusting. It is not a nice sight when you find them clustered in one place, especially in the summer when you can find more of them anywhere you go.

Sometimes you wonder how long for that torture to be over and feel like its forever since there isn’t only one of them, but a lot. However, you need to do two things, either to be patient or get rid of them with anything you have. Following this statement, sometimes it is not even needed to eliminate them as this all falls on their life cycle which we will discuss next. However, remember that they are pests, and bring issues to you and your family or pets. It is useful to know when this kind of situation is getting out of control, and you might need help.

Flies’ life cycle

When you ask the question how long do flies live, first you need to know that they have life cycle that they must fulfil before you see them floating around. It is made up of four different stages that are as following: egg, larvae, pupae, and adult.

First, the cycle starts with one of the adult flies lays an egg in a place where the conditions for its hatching are met. The ability of these insects to reproduces enormous as they do not only lay one egg but a batch of them going from 80 to 150. Which can be one of the six that the female will produce in her lifetime after it has reached its maturity in the second week of its adulthood.

Then, when the egg has hatched, the larvae start feeding right away. An egg can take as many as 20 hours to hatch (depending on the conditions). Larvae are also called maggots, which do not only need to feed but to molt too. They shed up to three different layers of skin because they go into their next step of development. Molting is part of their cycle, and they have three stages to do it, whose duration can go from three days to eight weeks depending on the weather conditions where the larvae is developing. In warmer weathers the larvae will molt sooner, rather than later in cool weathers.

Followed the development of the larvae, they will go into the next stage that is the pupae. Maggots start transforming and growing until they have become an adult fly. This happens for a while, up to 6 days in warm temperatures but the earliest can be four. When they are done changing forms, they grow wings and can finally reproduce and get food.

How long do flies live?

This question seems to be tricky to answer since flies have a natural ability, that is that they see the world at a different pace than ours because they perceive time differently, so if you try to kill one, it flies off quick because they are seeing what you’re doing in slow motion, helping them to escape.

Depending on the species, the lifespan will change. When you’re talking about a housefly, they tend to live up to 25 days in good conditions, counting all the stages that were previously mentioned. In colder weathers they don’t survive as much because of the temperature as they usually like warm places.

In these 25 days or a month, flies can carry out a big infestation if they are not removed as females can lay as many as 3000 eggs in a house and that is a lot to handle without professional help.

 Types of flies and their lifespan

There is not only one kind of fly, and their lifespan varies depending on the breed. Cluster flies are a special type of fly that lives in the soil, going through all its stages of development there, and only going to the surface once they have reached their adult stage. The duration of this process goes up to 40 days, and they can live for a year. However, they can’t breed indoors so they are forced to go out.

Other type of fly, that is not only one of the smallest ones, but it is not considered a pest, is the fruit fly. They live off decaying food, which is an advantage to humans since that kind of food is not going to form into a bacteria pool as they get rid of it. When the perfect conditions are met, fruit flies can live up to a month, although its average lifespan is only 10 days.

What do flies do in winter?

We have talked about flies living in tropical or warm weather, but for them it is hard to live in cold weather so their lifespan might be extended because of this. Sometimes they go into a kind of hibernation that is known as diapause. They stop feeding and remain in a halted state of growth. When they are adults, they just hide in a place and wait for the temperature to rise again and become active.

This is not their only technique, but they can also migrate to find a suitable habitat to develop and breed. One characteristic that they have is that flying long distances is not hard or uncommon for them.

In conclusion, flies do not live only for 24 hours as most people think, it is more than that. And something that you must pay attention to is the fact that this can lead you to huge infestations and not only that, but contamination of food among other things. Try to get rid of them as soon as possible.
