Flies are able to go without food for a surprisingly long time. In fact, research has shown that some species of fly can live for more than two months without eating anything at all. This is because flies are able to enter a state of dormancy when food is scarce, which helps them to survive long periods without food.

The life cycle of a fly

The average life cycle for a house fly is between 15 and 25 days. However, this is just an average and in some cases, flies have been known to live for as long as two months. The key to a long life for a fly is having a consistent food source. If a fly does not have access to food, it will not be able to live for very long.

What do flies eat?

Fruit flies, for example, can go without food for 12 days, but only if they’re kept at cool temperatures, around 50 degrees Fahrenheit. If they’re kept at warmer temperatures, around 80 degrees Fahrenheit, they’ll only survive for about two days without food.

How long can flies live without food?

Flies are able to live for long periods of time without food, but they will eventually die if they do not have access to water. A female housefly can live for up to 30 days without food, but only about 10 days without water. A male housefly can live for about 15 days without food, but only about 5 days without water.

Why do flies need food?

As any homeowner knows, flies are attracted to food. But why do they need to eat? What do they eat? And how long can they live without food?

Flies are attracted to food because they need it for energy. Like all animals, flies use food for two main purposes: to build new tissue and to produce energy. Flies use energy for flying, walking, and other activities.

The major difference between flies and other animals is that flies cannot store fat or glycogen (a type of sugar). This means that they must eat frequently during the day in order to have enough energy to power their activities. If a fly does not have access to food, it will starve and die within a few days.

What happens if a fly doesn’t eat?

Flies can go without food for longer periods of time than most insects. Adult houseflies can live for two to three weeks without food, but they only live for about a month if they do not have access to water.

How can you tell if a fly is hungry?

You can tell if a fly is hungry if it is sitting on the food or trying to get to the food.

What to do if you find a fly in your food

If you find a fly in your food, there are a few things you can do. You can try to remove the fly from your food without touching it, or you can kill the fly and then remove it. If you decide to kill the fly, there are a few ways you can do this. You can swat it with a fly swatter, or you can use a spray made specifically for killing flies.

How to keep flies away from your food

Flies are attracted to food by both sight and smell. They are able to locate food from up to 20 feet away! Once they land on food, they regurgitate saliva onto it, which breaks down the food so the fly can suck it up. Not only is this gross, but it can also contaminate your food with bacteria.

You can keep flies away from your food by following these simple tips:
-Keep food covered as much as possible.
-Clean up spills immediately.
-Store garbage in a sealed container.
-Use a fan to create a breeze near your eating area.


In conclusion, it is possible for flies to live without food, but their life expectancy is reduced. Without food, they will eventually die of starvation. However, if they have access to water, they may be able to survive for a few days or weeks.
