Hi, Fleas. I hate them. I have hardwood floor. I tried DE around the wall. I tried vacuuming everything. I tried spraying home defense whatever chemical around the wall. Kept getting new itchy stuff around my legs. How do I beat fleas? Do they come at night? Do they crawl or jump to my leg? Can they go through thin blanket? Socks? How soon will I see swelling/feel itchy after it bites? How long do they linger around my leg? Where do they hide? Do they come from chicken coop and find their way to my house? If not where do they come from? Do they jump onto my cloth, shoes or me when I'm near the chicken coop and then jump off later when they are inside my house? I had one of them jump onto my leg. I pushed it against me but it didn't die. It jumped off. How are they so strong? Thanks for any hints.
