MADISON (WKOW) -- Bed bugs may be thought of as being part of a dirty home, but according to exterminator Jim Muir, bed bugs don't care whether your home is clean or not, they just care about the blood your veins provide.
You know you have bed bugs if you get bite marks in groups of three. You might also notice small red and brown stains on top of your mattress.
Angie Hicks of Angie's List says you shouldn't just treat your bed. You need to also check the bed frame and carpet.
Bed bugs can go up to 18 months without eating. If they find a warm, dark place in your home, they'll stay there until something is done about it.
Angie says you should call pest control and talk to them about the process. It might mean you'll have to be out of your home for several hours, so make sure you set up a time that's convenient for you.
Muir recommends a heat treatment which involves several furnaces that will heat the area between 130 and 150 degrees. That could cost between $1,200 and $1,800 depending on the method and size of your home. You will also want to follow up with monthly chemical treatment to make sure nothing comes back.
