Asthma attacks result in high rates of emergency room visits, hospitalisation, periods of breathing difficulty, missed school days and sleep-deprived nights. The role of cockroach allergy in perennial rhinitis is, as yet unclear. A diagnosis of allergy to cockroaches may be confirmed using the CAP RAST test on a small blood sample sent to a laboratory, or by using a skin prick test. This is because many patients with cockroach allergy are also allergic to other allergens. Patients who have positive allergy tests to cockroach allergens should actively take steps to avoid exposure to cockroaches in their homes and workplace.
Cockroaches are very hardy and resistant creatures.
Crevices and possible portals of entry for cockroaches into the home should be sealed off. Fumigation should be arranged when numbers of cockroaches are identified in a home. Regular cleaning of cupboards and surfaces is essential. The covering of food and the sealing of garbage is also very important, as well as washing plates and dishes promptly.
