Bed bugs are not known to spread disease. Bed bugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection.
How Bed Bugs Spread. Not everyone is aware that bed bugs can be spread via humans: if a person goes to a hotel room that has bed bugs, and the bed bugs hide out on the person or on the person's luggage, the bed bugs can be spread to a new location. Because of this, no house is safe from a bed bug infestation.
Bed bugs do bite pets, but only when there is not a human host nearby. This means that as the insect senses a carbon dioxide signature, if the human is farther away (within 50 to 75 feet away) it will still migrate toward the human first. They prefer humans as a food source, but not because humans are easier to bite.
Bed bugs can spread from one room or apartment to another through door frames, windows, or holes or cracks in the walls, ceilings and floors. They can contaminate wood furniture by laying eggs in cracks and recesses, and when that furniture is moved, these eggs (which can stay viable for years) may hatch in a new location.
Bedbugs (or bed bugs) are small, oval, brownish insects that live on the blood of animals or humans. They often enter your home undetected in luggage, clothing, and used beds or couches.
PHILADELPHIA — The bed bug may be just as dangerous as its sinister cousin, the triatomine, or "kissing" bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi
