“…Cockroach allergen is one of the strongest risk factors for asthma among inner city residents [38]. Studies suggest that exposure to high levels of cockroach allergen in sensitized asthmatic individuals is associated with increased symptoms and risk of exacerbation [39].…”

“…A 2007 randomized controlled study by Sever and colleagues [38] compared the effects of two different abatement measures on cockroach populations and allergen levels within infested homes. The houses were randomly assigned to receive treatment by commercial pesticide companies, treatment by strategically positioned bait traps placed by entomologists, or to a nontreatment control group.…”

Children spend a considerable portion of their time indoors. Therefore, homes and schools are an important source of allergen exposure. Chronic exposure to the major indoor allergens can lead to allergic sensitization and provoke allergic symptoms in children. Environmental assessment is crucial for the identification and quantification of such allergens in indoor spaces. Reduction of allergen exposure below sensitization and symptom thresholds is possible with various remediation techniques. This article reviews and discusses evidence for the assessment and remediation of indoor allergens commonly found in homes and schools. A literature review was performed using the PubMed database for English-language articles published between January 1, 1980, and February 2009. Additional information was obtained from a review of recent textbooks and one professional society's webpage.

“…Until recently, however, there has been sparse evidence that cockroach control alone could attain longterm, clinically relevant reductions in cockroach allergens in infested structures. Sarpong et al (1996) and Sever et al (2007) clearly showed that cockroach control alone signiÞcantly reduced cockroach allergen levels in homes. The effect of cockroach control has not been shown in school settings, even though many schoolsÑin both urban and rural districtsÑare prone to cockroach infestations and have clinically relevant cockroach allergen levels (Sarpong et al 1997, Abramson et al 2006, Perry et al 2008).…”

Cockroach suppression is fundamental to cockroach allergen mitigation in infested homes. The effects of various cockroach control strategies on cockroach populations and allergen concentration have not been examined in schools. This study was conducted to compare the effectiveness of integrated pest management (IPM) and conventional pest control in controlling German cockroach (Blattella germanica L.) infestations and concentrations of the cockroach allergen Bla g 1 in public school buildings. Two school districts included six schools that used conventional pest control and one district included seven schools that used IPM to control pests. Cockroach traps were deployed to assess the level of infestation, settled dust samples were collected in food service areas, classrooms, and other school areas, and the Bla g 1 allergen was quantified by ELISA. Both cockroach counts and Bla g 1 concentrations were dependent on the pest control approach, with highly significant differences between IPM-treated schools and conventionally treated schools in both the cockroach mean trap counts (0 versus 82.6 +/- 17.3 cockroaches/trap/wk, respectively) and in the amount of Bla g 1 in dust samples (2.8 +/- 0.3 versus 30.6 +/- 3.4 U/g dust). Cockroaches and Bla g 1 were primarily associated with food preparation and food service areas and much less with classrooms and offices. Our data extend recent findings from studies in homes, showing that cockroach allergens can be reduced by cockroach elimination alone or by integrating several tactics including education, cleaning, and pest control. IPM is not only effective at controlling cockroaches but also can lead to long-term reductions in cockroach allergen concentrations, resulting in a healthier environment for students and school personnel.
