Cockroach allergen
  • A potent, pervasive and persistent asthma trigger for low-income, inner-city populations


  • National Cooperative Inner-City Asthma Study [1997]:
    • 37% of children allergic,
    • High levels in 50% of homes,
    • Sensitivity + exposure associated with morbidity measures


6
Small project to explore:
  • Safer and more effective elimination of cockroach infestation
  • Assessment of cockroach allergen contamination
  • More effective cleanup/ decontamination of cockroach allergen


7
Setting
  • 3 multi-family complexes operated by the public housing authority in Cleveland
  • 18 housing units enrolled
  • All units had been getting regular pest control treatment by a licensed contractor

General design

  • Confirm roach infestation
  • Eliminate infestation by IPM methods
  • Measure roach allergen
  • Conduct specialized cleaning
  • Measure roach allergen
  • Educate occupants on roach control
  • Measure roach allergen

Roach reduction by IPM
  • Visual inspection and sticky trap monitoring
  • Roaches flushed with a hot air gun and captured with a HEPA vacuum
  • Gel baits and borate powders placed in harborages identified by the flushing
  • Harborages and entry points sealed
  • Occupant education
14
Roach Control Team
  • Pest control contractor
    • Pesticide application
  • EHW staff
    • Flush & vacuum
    • Negotiate repairs
    • Take dust samples
    • Clean
    • Educate occupants

Tenant education
  • EHW Health Educator
  • Part of IPM & sampling team
    • Multiple visits, long duration
    • Build trust
    • Informal education
  • One-on-one and group education
  • Engaged children in process


21
Educational content
  • Roaches & asthma
  • Shared responsibility
    • Pest control contractors
    • Housing authority
    • Occupant
  • Roach food and water sources
  • Bringing roaches in and keeping them out
  • Problem of clutter
  • Working with the contractor


22
Working with the contractor:
  • Uncontained food and food waste feeds roaches and compete with baits.
  • Clutter creates harborages and makes it difficult to inspect and bait effectively.
  • Use of do-it-yourself sprays interferes with baits.

24
Pest control contractors
  • Followed important elements of IPM strategy:
    • spray pesticides rarely used;
    • highly toxic and volatile pesticides not used;
    • baits used widely
25
Pest control contractors
  • Limitations responding to large, persistent infestations:
    • flushing and vacuuming not used
    • gel baits too often the exclusive method
    • harborages in rooms other than kitchen often not treated
    • too little time was spent in a unit to inspect for harborages, monitor sticky traps and deploy baits
26
Changes needed in
  • pest control contracting (e.g., fee structure, contract specifications and performance monitoring)
  • training and supervision of pest control contractor personnel
  • maintenance and repair practices
  • tenant education and enforcement of responsibilities.
27
Shared responsibility
  • Housing Authority - provide and maintain dwelling unit free from defects that support roach infestation.
  • Pest Control Contractor - thoroughly inspect entire unit to determine roach harborages, entry points, and food and water resources; use safe and effective treatments to get rid of the roaches; and provide on-going monitoring.
  • Tenants - cooperate with pest control efforts by contractor and housing authority; maintain housekeeping practices that do not support roach infestation.
