How Fleas Change Color

Fleas are small insects and their color helps you identify them from other insects. They range from white to brown and often have spots and stripes to camouflage themselves. Fleas also change color depending on their age and what they’ve been eating. The color of an adult flea can be different from that of an unfed one by as much as two shades.

Sand fleas, for example, change color to blend in with their environment. They change color to match the sand they live in and match the rocks on a beach. This is not a surprising adaptation – many animals and plants have evolved camouflage to blend in with their surroundings. Most of these adaptations are genetic.

Adult fleas are brown or black in color. The adult fleas are approximately one-eighth of an inch in length. Fleas are difficult to see because they’re so small. Their coat is also very thick, making it difficult to spot them visually. However, it’s important to remember that fleas are tiny and move very quickly.

Flea dirt is another tell-tale sign that your pet may have fleas. The flea dirt is a mix of blood and flea poop. When soaked in water, it turns a reddish brown. You can also find flea dirt on your dog’s bedding, couch, and carpets.
