As a licensed pest control technician, I would advise you to hire a professional immediately. Bed bugs are extremely difficult to control. Your best bet is to hire a company to perform a heat treatment. They'll have to heat the house to above 115 degrees at the very least for a period of time. Expect the cost to ve around $1600 plus even for a small home. Chemical treatments are way less effective in my experience. I had one home that I had to treat 12 times before satisfactory control was obtained. This is a problem that you will not be able to treat with at home remedies. If you do the heat treatment you'll have to be out of the house and take your pets with you, but you should not have to throw out furniture or other possessions.
