Gene: My clients also tend to be affluent, mostly second home owners often working through a decorator. I have never taken in a piece that was infested with bugs. I have found many disgusting things in peoples furniture, once a giant bee hive, but never bed bugs. I am not one to fall for medias hype and I found most of my information on bed bugs through the Vermont Dep. of Agriculture, but it was the media that led me to looking into the situation. It seems since DDT was banned bed bugs have been making a come back and now are reported to infect one house in three. VT Dep. of Ag. believes it may actually be higher than that because many people are to embarrassed to report an infestation. I have heard that new furniture can be delivered with bed bugs if the truck used to make the delivery is also used to remove old furniture, especially mattresses. Bed Bugs can be picked up at movie theaters, restaurants, motels, any place people frequent. I would think you could pick them up if you rubbed up against the wrong person. Guests that come into your shop, or home could also bring along the uninvited little guests. I want to be proactive and take precautions against an infestation before it happens. I found whats called a bug tent on amazon, you put furniture, or any belongings in it and the interior is heated to 120 degrees F or better for a couple of hours. This is supposed to kill the bugs and any eggs, cost depends on size, but one big enough to put a sofa in is around $1500.00 and it takes 4 20 amp outlets to run the thing. I have heard that unless the spray in question is for bed bugs specifically results will be lack luster.
