Bug-bomb foggers are no match for bed bugs New research shows foggers are ineffective against bed bugs Consumer products known as “bug bombs” or “foggers” have been sold for decades for use against many common household insects. However, recent research published in the Journal of Economic Entomology (JEE) shows these products to be ineffective against bed bugs. In “Ineffectiveness of Over-the-Counter Total-Release Foggers Against the Bed Bug (Heteroptera: Cimicidae),” an article appearing in the June issue of JEE, authors Susan C. Jones and Joshua L. Bryant provide the first scientific evidence that these products should not be recommended for control of this increasingly worrisome urban pest. “There has always been this perception and feedback from the pest-management industry that over-the-counter foggers are not effective against bed bugs and might make matters worse,” said Susan Jones, an urban entomologist with the university’s Ohio Agricultural Research and Development Center (OARDC) and a household and structural pest specialist with OSU Extension. “But up until now there has been no published data regarding the efficacy of foggers against bedbugs.” Jones and research associate Joshua Bryant evaluated three different fogger brands obtained from a nationwide retailer, and experiments were conducted on five different bedbug populations. Following application of the three foggers, Jones and Bryant found little, if any, adverse effects on the bed bugs. Because a majority of bed bugs spend most of the time hiding in protected sites (under sheets and mattresses, in cracks and crevices, deep inside carpets, etc.), Jones said it is very unlikely that they will be exposed to the insecticide mist from foggers. And even if they do come into contact with the mist, she added, many bed bug populations have varying degrees of resistance to the insecticides, so they will most likely survive the application. “These foggers don’t penetrate in cracks and crevices where most bed bugs are hiding, so most of them will survive,” Jones said. “If you use these products, you will not get the infestation under control, you will waste your money, and you will delay effective treatment of your infestation. Bed bugs are among the most difficult and expensive urban pests to control. It typically takes a professional to do it right. Also, the ineffective use...

Acute Illnesses Associated With Insecticides Used to Control Bed Bugs — Seven States, 2003–2010   For 2003–2010, a total of 111 cases were identified in seven states (Table 2). The majority of cases occurred during 2008–2010 (73%), were of low severity (81%), and were identified by poison control centers (81%). New York City had the largest percentage of cases (58%).     Weekly September 23, 2011 / 60(37);1269-1274   The common bed bug, Cimex lectularius, is a wingless, reddish-brown insect that requires blood meals from humans, other mammals, or birds to survive (1). Bed bugs are not considered to be disease vectors (2,3), but they can reduce quality of life by causing anxiety, discomfort, and sleeplessness (4). Bed bug populations and infestations are increasing in the United States and internationally (3,5). Bed bug infestations often are treated with insecticides, but insecticide resistance is a problem, and excessive use of insecticides or use of insecticides contrary to label directions can raise the potential for human toxicity. To assess the frequency of illness from insecticides used to control bed bugs, relevant cases from 2003–2010 were sought from the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides program and the New York City Department of Health and Mental Hygiene (NYC DOHMH). Cases were identified in seven states: California, Florida, Michigan, North Carolina, New York, Texas, and Washington. A total of 111 illnesses associated with bed bug–related insecticide use were identified; although 90 (81%) were low severity, one fatality occurred. Pyrethroids, pyrethrins, or both were implicated in 99 (89%) of the cases, including the fatality. The most common factors contributing to illness were excessive insecticide application, failure to wash or change pesticide-treated bedding, and inadequate notification of pesticide application. Although few cases of illnesses associated with insecticides used to control bed bugs have been reported, recommendations to prevent this problem from escalating include educating the public about effective bed bug management. To evaluate illnesses associated with insecticides used to control bed bugs, data from 2003–2010 were obtained from states participating in the SENSOR-Pesticides program* and from NYC DOHMH.† Acute illnesses associated with an insecticide used to control bed bugs were defined as two or more acute adverse health effects resulting from exposure to an insecticide...
