Hello Mary - I know very little about fleas. I don't think I have ever seen "snow fleas." I have, however, seen mosquitoes even when there is snow on the ground. -Cheryl -------- Mary Sirucek wrote: Hello, I hope that you all are keeping warm. 5 above here with a wind temp of-15. About 60 years ago I was out in my farm yard and seen "little black dots" all over the snow...because we burnt woo, I thought it was soot. But on close look they moved. My Mother said they were "snow fleas". Have you ever seen these little critters up there? When I speak of them here, people laugh and say there are no such thing. Please, please, let me know if you all have seen them up there.
