Infested mattresses and box springs can be discarded or wrapped in plastic to trap the bedbugs. Washing bedding and clothes in hot water and drying with high heat can kill bedbugs and their larvae. Cleaning and vacuuming furniture and floors can also help get rid of bedbugs. Shake out suitcases after traveling. Only use an insecticide in cracks on floors or furniture in areas that do not come into contact with skin. An exterminator can help if you're unable to rid the home of bedbugs.
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.
Bed bug infestations have resurged since the 1980s for reasons that are not clear, but contributing factors may be complacency, increased resistance, bans on pesticides, and increased international travel. The U.S. National Pest Management Association reported a 71% increase in bed bug calls between 2000 and 2005. The number of reported incidents in New York City alone rose from 500 in 2004 to 10,000 in 2009. In 2013, Chicago was listed as the number 1 city in the United States with the worst bed bug infestation. As a result, the Chicago City Council passed a bed bug control ordinance to limit their spread. Additionally, bed bugs are reaching places in which they never established before, such as southern South America.
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
