What Size Are Flea Eggs?

It’s not always easy to tell what size flea eggs are, but this simple test will tell you if you have fleas. Fleas lay eggs all over the place, including your bedding, floorboards, and upholstery. They live in these areas until they hatch. You can check to see if you have any flea eggs by looking through a magnifying glass.

Flea eggs are translucent and less than one-half of an inch long. They are often accompanied by fecal matter, which is called “flea dirt.” This dirt is often hard to see, and it can even be confused with flea eggs. Flea dirt looks like a mix of salt and pepper and is very difficult to spot on light-colored fur.

Flea eggs can live as long as 10 days, but they need a humid environment between seventy and eighty-five degrees to hatch. In an ideal environment, flea eggs will hatch in 36 hours, but under less-than-ideal conditions, they can take up to 10 days.

Adult fleas are one-eighth of an inch long, reddish brown, and thin. They have a long, pointed proboscis that can puncture the skin while feeding. They produce an average of one hundred immature fleas per adult. You can also see dried blood specks on your pet’s fur. They will turn brown once rehydrated.
