Flea eggs are tiny and oval-shaped, measuring about 0.5 millimeters in length and half that in width, which is about the size of a grain of salt. They have a soft shell called a “chorion” that is off-white in color and shaped more like an oval grain of salt than a grain of salt. Flea eggs are almost transparent when freshly deposited, but they become more opaque and pearly-white as they mature. They are usually laid on the cats skin and fur, but they can also be found on their bedding or on the floor. Flea eggs are easy to mistake for dry skin or sand, so its usually not the first thing pet parents notice if their pet has a flea problem. To distinguish flea eggs from other objects, place the speck on a dark piece of paper under a magnifying glass to see the distinctively oval shape of a flea egg. Flea dirt, or flea feces, is often mistaken for flea eggs, but flea dirt is dark and crumbly, resembling black pepper.
