For a while now it wasn’t believed that bed bugs caused any diseases or any long-term problems. However, scientists now suggest that bed bug bites may do more harm than we previously thought. Regardless if they do or not, bed bugs can cause you a lot of problems. So, if you are having a bed bug problem, contact a bed bug exterminator right away.

What Diseases Do Bed Bugs Carry?

Common bed bugs are believed to carry over forty different disease-causing pathogens, and of which can affect humans. While bed bugs don’t transmit disease to humans as easily as other pests such as as mosquitoes, but their feces provides an easy channel for disease transmission.

Most notably, researchers have found that bed bugs can carry Trypanosoma cruzi which is the type of parasite that causes Chagas disease. This disease is most commonly found in tropical areas of the world. It is most commonly found in Mexico, Central America, and South America. The disease can cause fever, swelling, and heart problems, and the symptoms can range from mild to life-threatening.

Do Bed Bugs Cause Allergies?

What’s even more threatening is the fact that bed bugs can induce allergies in many people. Individuals who have asthma or other sensitivities may experience severe, in some cases life-threatening reactions, such as trouble breathing, swelling, and excessive itching. This is because bed bugs release histamine in their feces.



Bed bug feces, which can linger long after an infestation has been eradicated, can cause reactions for years later.

In fact, histamine levels in homes with bed bug infestations were roughly 20 times higher than those in homes without bed bugs.
