Bed bugs are challenging to eradicate. Since they can hide in so many places, inspections must be thorough and elimination is not always a certainty. Whenever resources allow, it’s prudent to enlist the services of a professional. Experienced pest controllers know where to look for bed bugs, and have an assortment of tools at their disposal. Nonetheless, owners and occupants can assist the professional in several important ways. Affording access to all living areas is crucial, and excess clutter will need to be removed. Belongings strewn about rooms offer many places for the bugs to hide, and impede inspection and treatment. Since bed bugs can disperse throughout a building, it often will be necessary to inspect adjoining rooms and apartments as well.
Pay attention to when the bites occur. Consider, for example, if you notice the bites after waking up when previously you hadn't noticed them. However, this can also be difficult to determine because each person's reaction time can vary significantly. Symptoms that result from the bite can manifest at any point from a couple of hours to more than a week after the bite occurred.

Bed bugs (Cimex lectularius) are small, flat, parasitic insects that only feed on the blood of humans and animals while they sleep. They are reddish-brown in color, about 1mm to 7mm in size, and can live for several months without a blood meal. Bed bugs are not known to spread diseases, but their presence can cause itching and loss of sleep. Excessive scratching can increase the chance of secondary skin infections. Bed bugs are found all over the world and the cleanliness does not determine the presence of bed bugs.
