The increase in bed bug infestations in the U.S. is a result of increased travel, lack of knowledge about preventing infestations, increased resistance of bed bugs to pesticides, and ineffective pest control practices, explains the Environmental Protection Agency (EPA). It’s easy to mistake bed bugs for carpet beetles or similar-looking bugs, so infestations are often not noticed when they first occur. Prevention tips include keeping areas free of clutter, regularly washing sheets and mattress covers in hot water (and don’t forget to wash the laundry bag, too), and vacuuming regularly and safely disposing of the sealed vacuum bag. Not everyone has reactions to bed bug bites, which also may be mistaken for the bites of other pests such as mosquitoes, so timely bed bug extermination depends on identification of bed bug activity. If you notice physical signs of an infestation, contact a bed bug extermination professional as soon as possible to learn about chemical and non-chemical (such as heat) treatment options. An integrated pest management plan may incorporate one or more methods.
