We have spider mites all over the inside and outside of our house. We have no house plants and no landscapeing outside. A friend in the bug biz. Says they sometimes are in the lumber when they build new houses and get in that way after a while. I have a baby and don't want to risk her health but they got to go TODAY. How do I kill every last one and stop them from coming back SAFLEY as possible. My wife is about to lose it so my life is hell PLEASE HELP ME!!
