The fleas are very small yet very annoying and dangerous insects. They are tiny and fast, and can cause irritation and disease to both humans and pets. Not to mention that fleas are connected with the Black Death, a devastating global epidemic of bubonic plague that happened in the mid 1300-s.

They are small insects with no wings, and with legs designed for jumping. They can jump up to 80 times their height, which is quite incredible. Imagine a human being able to jump 400 feet up in the air. Fleas can survive in a home even if there are no pets, as long as there are animals that shelter nearby. They can go for 100 days without a host, and can multiply quickly.

You need to pay special attention to fleas if you have a dog, or a cat that wanders outside. But even if you don’t have any pets at home, your children might come in contact with fleas when petting a random dog on the streets, or someone else’s cat.


It is believed that these insects have been around for millions of years, since the Mesozoic era. Scientists believe that the predecessors of fleas were much larger and had stronger mouth suckers that allowed them to feed with the blood of dinosaurs.

The first person to study fleas under magnification was Galileo, and he was followed by Robert Hooke and others. There are more than 2,000 known species of fleas today, and the most common ones are the cat fleas, the dog fleas, the human fleas and the Oriental rat fleas.


While most of them do not harm people directly, they can cause a lot of damage to your beloved pets. They can cause irritations of the skin, which makes them scratch and irritate the areas even further. But the biggest concern is that fleas can transmit a lot of diseases and parasites.

Among them we can find: tapeworms, flea allergy dermatitis, the cat scratch disease, the Hemotropic Mycoplasmosis and least but not last – plague. Some of these diseases and parasites can then be transmitted to humans too, thus making fleas dangerous insects that should be treated as soon as possible.

For every flea that you see, there are many more others you don’t. They are usually in other stages of their life, such as eggs, larvae and pupae. When they are in the final pupal stage, they can stay dormant for quite a lot of time. They will then emerge into adults as a response to vibrations. That’s why it is important to get a professional treatment that not only will eliminate the current fleas in your home, but will also prevent new ones from emerging.
