Mar. 8, 2005 -- Worried about kids' asthma risk? You might want to take a look at your address -- and call an exterminator.

Your home -- and bugs lurking there -- can affect children's chances of developing asthma, says a new study. What's more, those factors vary between cities and building types.

Cockroaches are the peskiest pests for kids with asthma, says the study. Keeping your home clean can help, no matter where you live.

"These data confirm that cockroach allergen is the primary contributor to childhood asthma in inner-city home environments," says Kenneth Olden, PhD, in a news release. Olden directs the National Institute of Environmental Health Sciences (NIEHS).

"General cleaning practices, proven extermination techniques, and consistent maintenance methods can bring these allergens under control," says Olden.

Insects aren't the only risk factor for asthma, which is rising in Western countries. Cigarette smoke and allergens from pets and mold are also asthma hazards. Having a parent with a history of allergy or asthma also raises a child's risk of getting asthma.

Battle of the Bugs

The study included a showdown between cockroaches and dust mites. Which bug triggered more trouble for kids with asthma?

Cockroaches won that competition. They prompted more allergies than dust mites or pets among more than 900 school kids aged 5-11 with moderate to severe asthma.

The kids all lived in inner-city neighborhoods in the Bronx (a borough of New York), Boston, New York, Chicago, Dallas, Seattle, and Tucson. They took allergy tests and had their homes inspected by the researchers.

Kids who were allergic and exposed to cockroaches missed more school, had asthma symptoms on more days, and had more unscheduled medical appointments for asthma. Their risk of hospitalization during the two-year study was also 45% higher.

According to the NIEHS, people can take the following steps to help reduce the risk of their exposure to cockroach allergen:

  • Eat only in the kitchen and dining room.
  • Put non-refrigerated items in plastic containers or sealable bags.
  • Take out the garbage on a daily basis.
  • Repair leaky faucets since water sources attract roaches.
  • Vacuum frequently to decrease allergens.
  • Regularly clean countertops and other surfaces that might have food debris and attract bugs.
