I have used the nopest for years and now they are Ortho. Work great, no bad side effects, my hair is falling out and my nails bleed, gum's too. But other than O ya the rash, but it's worth it.... Just fucking with you, if you don't live with them don't worry, if you do try to minamise your exposure to them. My parents used them all my life at the cottage and I did also.
I also have used Doctor Doom bombs with good success in the past.
