I heard about salt, but I don’t think I can vacuum daily. Anyway, a pest control company came, and I’ve not seen a single flea for more than a week now, but I read that some of the eggs that might have survived may develop into adults in 7-14 days after treatment, so I still take precautions to prevent possible bites (by wearing long sleeve-clothes and spraying vinegar on my body). I have also put flea traps in many rooms; if I caught any of them, I would call the company again to eradicate the rest of them.
