What do fleas look like?
Fleas are parasitic pests that feed on the blood of their hosts. There are many different species of fleas found living throughout the United States. Some of the most common fleas to cause problems for people and pets are cat fleas. Adult cat fleas are shiny and dark brownish-red in color. They are wingless and have flat, hard bodies which protect them from being squished.
Fleas are commonly identified by their long, powerful back legs. They have a 6 to 8-inch vertical jump, allowing them to move quickly away from danger. Fleas are small in size (about the size of a fleck of dirt), and adults only grow to between 1/12th and 1/6th of an inch in length.
