Donna had been dealing with a persistent flea problem in her apartment for months and decided to take care of the fleas once and for all. She used 4 "bug bombs" to treat her small apartment, placing one in each room. She left during the treatment and returned later that evening. She kicked off her shoes and sat down on the sofa to watch TV before going to bed. Donna woke up in the middle of the night with a tingling in her legs and feet. She became concerned the tingling sensation might be caused by the flea treatment and got up to check one of the container labels. As she read through the label information for the first time, she learned ONE fogger was intended to treat 5,000 cubic feet. Donna quickly calculated the cubic feet of her home and was shocked to discover she needed only two foggers, not four. She had used twice the correct number of foggers and, in addition to her health concerns, now wondered if she should be worried about the amount of the pesticide in her home.
