In fact, the feds warned that it was often human errors—excessive use, failure to wash treated linens, and failure to follow label instructions—that led to the illnesses.
Nevertheless, the cases were alarming enough for the CDC to warn people of the insecticide poisoning's danger. And they've also got this additional, more disturbing note:
"Although the number of acute illnesses from insecticides used to control bed bugs does not suggest a large public health burden, increases in bed bug populations that are resistant to commonly available insecticides might result in increased misuse of pesticides."
In other words, it'll be even harder to kill the little pests.
Bed bugs, of course, don't carry disease. But, in the overly clinical words of the CDC, they "reduce quality of life by causing anxiety, discomfort and sleeplessness."
