Many people wonder how long fleas live . Fleas are external parasites that feed on the blood of their host.
One of the most widespread fleas in the world is the one known as the “cat flea” (Ctenocephalides felis) , which can infest different animal species, including dogs and humans.
It is crucial to control these parasites in our pets, since, during the lifespan of a flea, in addition to the uncomfortable itching they cause, they also:
- Can transmit other parasites in larval or immature stages, such as Dipylidium caninum , or the bacteria responsible for bartonellosis* and some rickettsiosis* (although most rickettsiosis is transmitted by ticks).
- Can cause weakness and anaemia especially in puppies and young kittens.
- Can cause some dogs and cats to develop an allergic reaction to the bite of these parasites, known as flea allergy dermatitis (FAD).
- Can cause itching in us and represent a risk of spreading diseases to our family.
What is the life cycle of fleas?
How long do fleas live? To know how long a flea lives, it is necessary to understand its life cycle.
This cycle comprises four stages: egg, larva, pupa, and adult. Only the adult flea feeds on the blood of its host (it is haematophagous), whether it be our dog, cat, or even us.
Adult females lay up to 50 eggs daily on the host’s hair. These eggs will fall to the ground, and the larvae will hatch from them.
Flea larvae find their habitat in dark places, such as inside carpets, upholstery, our pet’s bed, blankets, and even our own bed, where they feed on organic matter. Once they have completed their development, they transform into pupae.
The pupae remain dormant for an average of 8 to 13 days, until environmental conditions are favorable. This occurs when the temperature ranges between 12 and 32 °C, the relative humidity is 50-90%, and they sense the presence of people or pets, as they detect movement, noise, and body heat.
Under ideal conditions, the flea life cycle can last only 12 to 14 days, but in a typical home, it can extend to three or four weeks. However, in adverse conditions, such as cold climates, the cycle can take up to 174 days longer.
This knowledge is crucial for preventing and controlling flea infestations, as interventions at any of these stages can be effective in breaking the life cycle and preventing the proliferation of these parasites in our homes and on our pets.
Common mistakes in flea prevention at home and on your pet
We see problems controlling these parasites daily due to:
- Failure to provide year-round prevention exposes animals to infestations and the risk of contracting diseases transmitted by them.
- Do not treat all the animals in the house at the same time. Animals that have not been treated will become reservoirs for new fleas.
- Not providing prevention at the correct frequency. As we mentioned, flea eggs in the environment can take more than 30 days to develop into adult fleas; that is, when monthly treatments are used and their application is missed at the correct interval, the fleas will re-infest the animal.
