Ever since my "sister in law" brought her stupid mangy dog out here there have been fleas all over me and everything else! I've tried powders, sprays, salt, washing everything over and over, but they are still everywhere!

Any suggestions on how to get rid of these nasty things? I really just want to get the hell out of here! I took off my shirt earlier and there were 7 of them on my stomach! It makes me kind of sick...

My bf, his dad, his sis and her kid live here too, and I cant get them all cordinated enough to pack up all their clothes/bedding and do what has to be done. Should I burn all their shit? Should I give up and hitch hike to LA?
