How Long Do Fleas Live without a Host Animal?

how long do fleas live without blood

This is the common question that comes to our mind.

Can fleas live for days without feeding on a host?

Here is the quick answer.

If a flea is feeding on a host animal for some days, and you just removed it from the host, then it’ll die within 3 to 4 days due to starvation.

While young fleas that have not fed can survive longer for up to 155 days without feeding.

These details give below will help you to understand this question more clearly.

How Long Can Fleas Live without a Host?

Fleas within Cocoons

Cocoon is a silky case that is spun by the larvae for their protection from the environment.

In the cocoons, these larvae or fleas stay in the stage of inactivity like they hibernate for a longer period of time. In that stage, they don’t do any activity, their metabolism get slowed and that allows them to survive for a longer period of time.

If they get the optimum temperature, then the fleas within cocoons can survive for up to 4 to 5 months.

And, as soon as they get near a host on which they can attack, their quiescence ends.

So, fleas with cocoons live 4 to 5 months without feeding under optimum temperature.

Adult Fleas but Unfed

Adult fleas that have been come out from their cocoons must find a host. If they don’t get blood, they will die because of starvation in a few days.

If they get the optimum and favourable weather condition that is a humid environment, they can survive for a longer period of time. In some experiments, it is observed that unfed fleas can live for up to 35 to 40 days.

But, we don’t live in the weather conditions that are ideal for fleas.

So, in the weather conditions in which you live, you can expect unfed fleas will live for 1 to 2 weeks without a host animal.

Adult Fleas Feeding on a Host

If a flea fed on a host for a few days, say 5 days. Then it depends dependency on blood to stay nourished.

So, if you separate an adult flea that has been feeding on a host for a few days and has developed a dependency on it, the flea will die within 2 to 4 days without a host blood.

Female fleas need to feed regularly in order to produce eggs. Therefore, a female flea can die within 24 hours after the separation from the host.

While, if a flea didn’t reach the dependency then they can live for up to 2 weeks.
