Bed bugs are a difficult pest to control. This is mainly because they often hide out of sight in hard to reach areas such as baseboards, under carpeting, and inside various cracks and crevices throughout the room where pesticides cannot reach. Unfortunately, even when accessible, bed bugs are resistant to most modern day pesticides that which will have either little to no effect on an infestation or worsen it by causing bed bugs to scatter when chemicals are applied. In recent years, there has been a resurgence of bed bugs, largely due to increased foreign travel and increased sales of used furniture. Despite the name, bed bugs do not only reside in beds; they can also infest clothing and other furniture. Bed bugs can be brought into a business by a variety of means: carried in on clothing or luggage, brought in on furniture or bedding, or carried by wild animals such as birds.
