Can Fleas Be Seen by the Human Eye?

Fleas are very small, so you can’t see them with the naked eye, but if you look very closely, you can see them. They range in size from a quarter of an inch to about an eighth of an inch. They are flattened with long claws on their legs, and have a number of adaptations that help them move between hair shafts. Fleas also have spines on their legs, back, and mouth.

Fleas don’t have wings, but they’re good jumpers. In fact, an adult flea can jump as far as 30 centimeters horizontally and 18 centimeters vertically. Fleas are hard to see because they have a color that blends in with their host’s fur and a thick abdomen, so it’s difficult to spot them with the naked eye. However, if you notice specks in your pet’s fur, these are the fleas’ blood. This dried blood will turn brown when it’s rehydrated.

When your pet starts scratching at night, it may be a sign of a flea infestation. A flea infestation can cause many problems for your household. It’s important to get rid of them as soon as possible. Fortunately, there are several ways to detect and get rid of a flea infestation. In the first instance, you can try a flea shampoo. Depending on your area of residence, you may not have to treat the entire house.

Adult fleas can live from 12 to 18 months. If they have a perfect environment and a source of blood, they can even live longer. However, once they no longer have a host, they will die. In the meantime, fleas lay eggs. Flea eggs are semi-transparent and shiny. They are about half a millimeter in length and 0.3 millimeters wide. They can be seen by the human eye if they are close to their host.
