Can gerbils get fleas?

[Natalie Brown]

Can gerbils get fleas? my female gebil has a few teeny tiny blk. bugs on
her fur. They're smaller than fleas. What are they and are they harmful?
how do I get rid of them? are they harmful to soon-to-be-born pups?
Please respond asap with any information. Thankz
