Just like cats, dogs, or pollen, cockroaches can cause allergies. Enzymes in proteins found in cockroaches are thought to cause allergic reactions in humans.
These proteins are found in the saliva and excrement of cockroaches. They can easily spread through homes, much like dust.
Statistics show cockroach allergies are one of the most common worldwide indoor allergies. They can affect both adults and children, though children are known to be most susceptible. Despite this, people may not realize they have them. Research on cockroach allergies only began in the 1960s.
Fortunately, there are ways to know if you have this allergy. Doctors can diagnose a cockroach allergy and there are treatments you can try at home for relief.
