However, low-level infestations are also much more challenging to find and correctly identify. Other insects, such as carpet beetles, can be easily mistaken for bed bugs. If you misidentify a bed bug infestation, it gives the bugs more time to spread to other areas of the house or hitchhike a ride to someone else's house to start a new infestation. Learn about identifying bed bugs.
While the former methods are helpful, insecticides are widely used by most pest control companies. A variety of EPA-registered materials are available formulated as liquids, dusts and aerosols. Baits used to control ants and cockroaches are ineffective in this case since bed bugs must bite and feed on blood. Professional-use insecticides such as Temprid®, Transport® and Phantom® tend to be more effective than bed bug sprays sold by retailers. Bleach, alcohol, cigarette lighters, etc. should NOT be used to control bed bugs. Besides being ineffective, such actions can result in fires and other dangerous outcomes.   
Caregivers, firefighters, and other service providers are sometimes required to enter and work in bed bug-infested dwellings. In doing so, there is the potential to transport some bugs home or to the workplace. It should be noted that bed bugs do not fly, nor jump onto people/pets as fleas do. During the day, bed bugs usually remain hidden and immobile, becoming more active at night when seeking a host. Consequently, the chance of picking up bed bugs by merely walking into an infested dwelling during the day is unlikely. The risk may increase while providing care but can be lessened by taking some precautions. 
Cracks and crevices of bed frames should also be examined, especially if the frame is wood. (Bed bugs have an affinity for wood and fabric more so than metal or plastic.) Wooden support slats, if present, should be removed and examined since bed bugs often congregate where the ends rest on the frame. Screw holes, knots and other recesses are also common hiding places. Headboards secured to walls should be removed and inspected. In hotels, the area behind the headboard is often the first place that bed bugs become established. Bed bugs also frequently hide within items stored under beds. 

The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
