Researchers at NCSU have published a study showing that “Total Release Foggers” (or “TRFs”) are ineffective at controlling German cockroaches.  The study published in BMC Public Health  found that the foggers do not reach areas where cockroaches may be hiding and can increase pesticide concentrations in homes by as much as  600X (a median of 85X).  Baiting is far more effective at controlling German cockroaches and reducing potential asthma triggers that result from infestations and the use of certain insecticides.
