My neighbour, curse her, has given me fleas, so they are now in my animal-free house. I found one and killed it, but think there are a few more lurking around. I have no pets to spray/dose, and two small toddlers, so chemical sprays are out... what can I do other than hoover lots and wash all laundry, and I dont think that kills them anyway?? It's driving me mad, I am covered in bites...
