Can Fleas Survive Without a Host?

Fleas can survive without a host for a few days or even a few weeks, but they cannot survive for very long. This is because they need a host to lay eggs. A flea will only lay eggs if it has received a blood meal from a host. Fleas will usually feed every 12 hours. However, if they are not provided with a blood meal, they will begin to starve.

Once they have a host, fleas will emerge from their cocoon. After consuming blood, female fleas will lay eggs, which will hatch in one to two days. Then, a new batch of fleas will emerge from their eggs, starting a new cycle of life. Fleas feed mostly on cats, but can also infest humans, dogs, and indoor plants.

A flea infestation can spread in the home if a previous pet has left flea eggs on the floor. They may have spread the eggs from the previous pet through your clothing. Alternatively, you may have picked up a flea from the pet’s coat. You will need to clean these surfaces regularly to keep the fleas out.

Fleas cannot survive on light bulbs. They are attracted to hosts that often venture into the sunlight. There are many factors involved in determining whether fleas can live without a host.
