LOL! You don't have to have your whole house fumigated to get rid of bed bugs, but I understand the desire!! If you will leave your sheets and blankets pulled back for a few hours each day after you get out of bed - this will allow the area to cool down too far for bed bugs to proliferate.
Plus, if you find yourself with bed bugs - go grab some fresh sage (works best) or oregano (works decently) and put it under your bottom sheet for a few days. The first night I will still get a few bites, but by the second night, they are completely gone.
Experience. Priceless, but a hard way to learn!!
