Cockroaches and Other Pests

Cockroaches are commonly found in crowded cities and the southern regions of the United States. Cockroach allergens likely play a significant role in asthma in many urban areas. Certain proteins are found in cockroach feces and saliva and can cause allergic reactions or trigger asthma symptoms in some individuals. 

The protein in urine from rats and mice is a potent allergen. When it dries, it can become airborne. Droppings or body parts of cockroaches and other pests can trigger asthma. 

Actions You Can Take

Pests need food, water, and shelter. Remove these to reduce pest problems.

  • Repair screens, close openings where pests can enter. Caulk hiding places such as baseboards and cabinet edges.
  • Reducing clutter
  • Maintaining clean dining and food storage areas (counters, sinks, tables, floors)
  • Removing standing water
  • Fix water leaks and clean dishes, crumbs and spills right away
  • Store food in airtight containers
  • Use insecticides and pesticides safely, as these can be toxic to people too
    • Read the label and follow the directions
    • Keep them in their original containers
    • Store containers so children and pets cannot reach them
    • Do not use outdoor insecticides or pesticides inside the home/building
