Yes, we may have! The allergic symptoms may vary from mild ones to severe and persistent asthma. The first report was made in 1943, after the insects walked over a patient skin and he developed skin rashes. The skin tests confirmed, in 1959, that some patients had cockroach allergy. Later, it has been proved that the patients may also develop acute asthma attacks. The attacks may occur right after the patient gets in contact with the insect allergens and it lasts for hours.
We have research results showing that 23 to 60 percent of the urban population with asthma is sensitive to cockroach allergens. Those allergens derived from feces, saliva and the bodies of the cockroaches, affect patients not only by contact but also when those allergens are inhaled, they may trigger the asthma attacks. Studies in USA calculate that almost all urban houses have cockroaches, in an astonishing and really frightening amount of 900 to 330,000. They easily invade our houses and it is really hard to get rid of them.
Most insecticides are ineffective. They are resistant survivals. Only pest control experts may reduce their population at home. The use of common insecticides may worsen the allergic symptoms. People must cover food, dishes, cups, glasses, and garbage to avoid the proliferation of the cockroaches, and contamination of food. In extreme cases may be used “allergy injections”, kind of a vaccine, prepared with cockroaches extracts.
