Cockroach bite symptoms

The bite of a cockroach can cause allergic reactions in a variety of situations:

  • Whenever your immune system reacts to proteins in cockroach saliva, feces, or body parts;
  • Cockroaches that come into contact with skin;
  • By inhaling the allergens found on the waste matter and on the body of the insect;
  • When you are exposed to an area where a cockroach infestation was once presented (because of the capability of the allergens to become airborne).

As a result of the bite, the white blood cells of the bite victim attack cockroach allergens. Symptoms vary from person to person depending on their health.

Bites Can Cause Allergic Reactions

When cockroaches bite asthmatic people, they may feel inconvenient. Despite their bites not being dangerous, the pests carry allergens that can cause allergies.

This is not caused by the bite but by the allergens carried by the pest. Eliminate the pest by calling a trusted pest exterminator in Denver if you do not want to experience allergic reactions.
