Can Fleas Walk on Walls?
WouterIf you live in a house that is infested with fleas, one of the first questions you might ask is, “Can fleas walk on walls?” The answer is a resounding “yes.” While fleas do not squeeze into outer walls or foundations, they do easily squeeze into existing holes in a house.
It is important to note that fleas do not normally walk on walls, but they have been observed climbing them to escape pesticides. Unlike bedbugs, fleas have flattened bodies, so they can easily jump on to walls. Also, they tend to hide in a person’s mattress or bedding, so it is harder to notice them until you notice the itchy bites.
Although fleas do not have wings, they do have resilin, a special substance that is vital to flight. They use this to absorb tension from their wing strokes, which is why they can jump up to a hundred times their body length. This allows them to travel faster and farther than a human could.
Fleas are tiny, blood sucking insects that live on various mammals. They are reddish in color and about an eighth of an inch long. They have six legs and thin bodies. Their legs are long and have claws on the sides. They also have a spine on their legs, mouth, and back, which allows them to move around more easily.
