Idk where this goes

Fleas are seriously pissing me off! We have no animals our yard is full of fleas and they keep coming inside on our clothes or shoes and we get them out and they’re right back everyone we know uses this powder from tractor supply in their yard to get rid of them that works wonders we’re getting it tomorrow but these things have bit the living hell out of me I’m so sick of them has anyone had this problem before???
