Common Asthma Trigger #3: Cockroaches
Cockroach allergens have become an important public health problem in recent decades, especially in inner-city homes and schools. Their allergens are found in saliva, faecal material, secretions, cast skins, debris and dead bodies. Cockroach allergens may be more harmful than allergens from dust mites. Controlling and reducing cockroach allergen exposure is difficult and can take many months of treatment.
What can I do?
- Remove food sources and household food waste.
- Thoroughly clean infested areas first by general means. Then treat areas with insecticides and pesticides incorporated in gels or baits. Cleaning with sodium hypochlorite (bleach) has also proven helpful. Repeat after 1 or 2 weeks.
- Remove access to water from leaking taps or condensation on pipes.
What else can I do?
- Remove and wash bedding, curtains, and clothing.
- Consider contacting integrated pest management specialists.
- Protect food sources to reduce risk of reinfestation.
Please note that these recommendations are preliminary and more scientific research is needed.
