3 Reasons Fleas Are Detrimental to Your Pet's Health

May 7th 2016

Since fleas are a common pet problem, your pet catching them should not cause you any shame. However, handle infestations rapidly and effectively to prevent the spread of the insects and any detrimental consequences to the health of your pets and the rest of the household.


Fleas live on your furry pets because they feed on warm blood. Each flea can consume up to 15 times its own weight in blood, so once a colony starts breeding, the blood loss for your pet can become significant. This is because each adult female flea is able to lay up to 50 eggs every day, meaning that any flea population expands exponentially unless dealt with early on. A pet who loses too much blood is likely to become anemic over time, becoming listless and tired.


As well as reacting to the standard itchy bites, some pets are irritated by flea saliva or droppings and develop a full-blown allergy. Allergy symptoms include hair loss, scaly skin, scabs and skin infections. The resulting allergies and infections are uncomfortable for your pet, potentially infecting other animals and humans in the household.

Disease Vectors

Because fleas travel from animal to animal puncturing the skin and extracting blood, there is a risk of them transferring blood-borne diseases. These include bacteria, viruses and even tapeworms. Any of these puts your pet at risk. Despite animal fleas not being able to live on human blood, some also try to bite humans, and there is also a risk of disease transmission at that point.


Fleas, a bloodsucking, parasitic life form, are usually considered a nuisance but not a major problem, despite their bites and the droppings they leave behind. However, these insect pests can cause a range of illnesses and conditions that are much more harmful than itchy skin.
