Identifying and avoiding those triggers that cause an individual's episode can be as effective in the management of asthma as a strict medication regimen. Dust mites is a common indoor allergen. Routine clothes washing is not always effective. Often boiling laundry water to 130 F is necessary to kill dust mites. Changing air filters and having carpets treated also can help substantially.
Cockroaches can be an asthma trigger.
Removing garbage daily, storing food tightly and using cockroach bait can keep them from infesting your home. Also, pets can have a strong impact on asthma sufferers. Never let pets in your bedroom, since that is where you spend most of your time. Bathe animals frequently. Keeping them outdoors is the best advice.
