Get a professional pest control company to come out and spray your house. We did just externally last time and it worked a treat. It's very safe (safer than surface sprays according to the experts), you don't even have to leave the house. That said, I took DD out for the afternoon. It didn't smell or anything but the amount of dead spiders laying around afterwards was scary!! We'd only finished building the house a year earlier!!

My mum was bitten by a whitetail when we were kids. She didn't feel a thing but jeez it made a nasty mess on the back of her knee. It eventually cleared up thanks to lots of vitamins. She was lucky, the wound was foul!
