Because after one night there DC is covered in over 30 flea bites. Worst part is they're mostly in his nappy area, as fleas are attracted to urine. Poor little thing is really uncomfortable.
I know it'll cause stress, but I'm just sick of having to put up with the state of their house. It's filthy, full of dust and in a massive state of disrepair. I've grinned and bared up to now, but I don't want DC to have to.
