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.
