Need to vent!!!!

So my sister's uncle died (we are half sisters he's not my uncle). She asked me to watch her dogs so I was like OK. What she didn't tell me is they have fleas which are now in my home! I am so angry/frustrated. I am stuck with them until she gets back but the fleas are bad :( I keep my home so clean and I'm just frustrated. This is not OK. I'm getting bombs and going to ask her if I can give both a flea bath without getting bit. If anyone has any advice on killing fleas I would love for some ideas. I wish she would've told me! I have a child this is NOT OK.
