We have lived in the same house for almost a decade. We have never had any pets and haven’t even had anyone else’s pets in our home recently (within at least 6 months or more). Just in the last 24 hours I’ve started seeing quite a few fleas on my feet and lower legs (summer clothes…shorts and no shoes). And these are definitely inside the house; not brought in from outside. I would have thought without pets the possibility of getting a fleas infestation inside our home would be remote at best. And they’ve appeared so suddenly. Have never noticed any before about 24 hours ago. We keep a relatively clean house (vacumning about once a week usually). So ultimately I wanted to know if this is a situation you are familiar with and how common (or uncommon) is it?
