If you want to look at dog flea eggs, get out your magnifying glass and your knee pads. They are almost invisible to the naked eye, and you won't find them where you might think they'd be.
Size and Shape
Dog flea eggs measure about 0.05mm or 1/50 of an inch long. Think of a grain of sand or a single salt crystal. They are ovoid or egg-shaped, with one end slightly larger than the other.
Color and Texture
At pinhead size, dog flea eggs appear white, but under high magnification are translucent and have an iridescent sheen like mother-of-pearl. The surface is smooth and regular, with no lumps, bumps, ridges or projections, and is dry and not sticky.
The most likely spot to find dog flea eggs is where a dog sleeps, but they go anywhere the dog goes. Laid on the dog by a female adult, they do not cling to the dog's coat, but fall off or go airborne within a few hours as he moves around. They end up in his bedding, in the damp and shady places outside where he likes to snooze and in your house -- in furniture, rugs and carpeting and in cracks and seams in hard flooring. There they hatch into larvae, which progress to pupae, which hatch into fleas ready to bite and lay more eggs ... all in as little as seven days!
Get rid of flea eggs and you get rid of about half the problem. Wash your dog's bedding in hot, soapy water every week. Vacuum thoroughly (pay special attention to the corners and along the baseboards) and toss the bag or disinfect the cup -- otherwise, flea eggs can go right on hatching and developing in there. Bathe and flea-comb your dog often and regularly. Persistence will get results.
