Summary

Background:

\- Cockroach allergies are an important risk factor for asthma in inner-city households, especially in children. A new method for killing cockroaches may help children who live in households that have high numbers of cockroaches. Because most public health treatments target more than just cockroaches, this method could lower the costs of treating childhood allergies and asthma by focusing on the most likely source of the allergy.

Objectives:

\- To test a new cockroach-killing method designed to reduce asthma in children exposed to cockroaches.

Eligibility:

* Children 5 to 14 years of age who have moderate to severe asthma.
* Children must live in a household that has a high number of cockroaches.

Design:

* Participants will be screened with a phone call and an initial home visit.
* Study doctors will place cockroach traps, and return after 3 days to check the number of roaches caught and killed. Dust samples will be collected from the house.
* Participants will have blood and lung function tests, and will be tested for allergies (including cockroach allergies).
* Some households will be treated for cockroaches at regular intervals, or more frequently if required by the study doctors.
* Participants will have regular checkup visits in their homes at months 1, 3, 6, 9, and 12 and short phone call interviews at months 2, 4, 6, 8 and 10 to study their asthma symptoms. The home visits will also check the cockroach levels in the house.
