Bed bugs do not transmit MRSA. Although there have been reports of persons developing methicillin resistant Staphylococcus aureus (MRSA) infections, such as boils or abscesses associated with bed bug bites, it turns out the bed bugs really weren't directly at fault. Rather, the cases of MRSA infections associated with bed bug bites are actually an example of scratching leading to minor skin trauma and subsequent secondary bacterial infections. In these cases, people who are carriers of MRSA scratch at the itchy bite sites and provide a port of entry for the MRSA (which was already present on their skin) to get in and under the skin and cause the secondary infection. While it can be blamed for some other bed bug symptoms like itching and red welts, the bed bug cannot be blamed for the infection.
First, make sure that the suspected bugs are bedbugs, because other insects or arthropods such as a carpet beetle, scabies mite, a bat bug, louse, or other bugs may be mistaken for bedbugs. If there is confirmation of a bedbug infestation, several measures can be taken to help control or eradicate the infestation, using both nonchemical and chemical (insecticides) methods. It can take several weeks to months to achieve complete eradication of a bedbug infestation, and it may take several treatment cycles to completely eliminate them. In many cases, it will be necessary to hire a pest control service in order to implement a comprehensive extermination strategy.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
