Weeping at the washing

Here’s a nasty story. Our house has fleas. They only bite E, we’ve fumigated, fleas sprayed, treated the cat but last night I caught one on her FACE when she got into bed. So I’ve stripped and washed the entire contents of her room, including smellie Ellie. Who apparent,y doesn’t like the washing machine. . I wish we could figure out how to kill the little f*ckers.
