Need to call an exterminater asap.
I agree. You need an exterminator.If you miss just one pregnant female bed bug you can be reinfested with over 300 adults and 1000 new eggs in three months.
Bug be gone. I vacuumed my furniture and mattresses every day, and sprayed all the nooks and crannies with this product. It took a while, but if your diligent, you can do it. I bought the product in its bulk rate, kept one in the bedroom and one in the living room. The lil buggers will catch rides on your clothes and pets.

Professional exterminator is the only way to go. Otherwise you will unknowingly spread to every place you visit. I can tell horror stories until the cows come home.
