    ~~~~Got a bug bite problem? Many people who are troubled by skin rashes caused by bug bites use “foggers,” or “bug bombs,” to get rid of the annoying crawlers in their homes. Many people think these bug killers or pesticides will penetrate every place where the insects hide. Actually, quite the opposite is true. Once the pests detect the chemical fog in the room, they’ll hide themselves in walls or other hideaways, where you’ll never be able to treat them effectively.
    ~~~~Ohio State University researchers tested three commercially sold foggers in a study on the effect of foggers on bedbugs. After testing these brands on five different groups of live bedbugs for two hours, the scientists saw that the foggers had little—if any—effect on the insects. The researchers said bedbugs hide in cracks and crevices such as under sheets and mattresses, or deep in carpets where foggers won’t reach. Moreover, bugs that do come in contact with the mist may be resistant to the pesticide.
    ~~~~Foggers, or bug bombs, should really be a measure of last resort. First of all, the gases used in bug bombs are highly flammable and thus pose a serious risk of fire or explosion if the product is not used properly. Second, once a bug bomb is used, every surface in your home will be covered with the toxic pesticide. When you use a bug bomb, a chemical mixture rains down on your counters, furniture, floors, and walls, leaving behind oily and toxic substances. Your health might thus be endangered. Therefore, it is suggested that people leave the problem to the professionals.
