How do you tell the difference between a male and female flea?

Answer 1

Yes, a male flea is slightly smaller than a female, the female will have a sort of amber, sometimes redder tinged back end and a darker front, the male will be smaller and all black/dark brown.

Answer 2

Male fleas are typically smaller than female fleas and have a more pronounced genital opening on the lower part of their abdomen. Female fleas have a larger, rounder abdomen due to the presence of ovaries and eggs. It can be challenging to distinguish between the two without magnification due to their small size.
