The answer to 'what do flea look like' is that fleas are small, wingless insects that are typically reddish-brown in color and about 1-4 millimeters long. They have a flattened, oval-shaped body and six legs that are adapted for jumping, allowing them to move quickly across surfaces. Fleas have a hard exoskeleton and can be difficult to see with the naked eye, as they are quite small.
Fleas are known for their ability to jump up to 13 inches high and 8 inches long, making them agile and hard to catch. They have a mouthpart that is shaped like a proboscis, which they use to pierce the skin of their host and feed on their blood. Fleas are commonly found on pets, such as dogs and cats, but can also infest human homes and bite people.
