Also, hanging a black light in the middle of each room and leaving it on overnite might give you more peace of mind about surfaces.
Unfortunately, that's about all it will do. Consumer "black light" bulbs have a peak emission at about 370nm, and the wavelengths that are effective for killing creepy crawlies lie between 200nm-300nm. And neither of those wavelength ranges is good for plastics. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
