Bed bugs are basically parasitic insects of the cimicid family that feed exclusively on blood. The name “bed bug” is derived from the preferred habitat of Cimex lectularius: warm houses and especially nearby or inside of beds and bedding or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed. Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Bedbugs prefer exposed skin, preferably the face, neck and arms of a sleeping individual. Although under certain cool conditions adult bed bugs can live for over a year without feeding, under typically warm conditions they will try to feed at five to ten day intervals and adults can survive for about five months without food.
It takes between five and ten minutes for a bed bug to become completely engorged with blood. In all, the insect may have spent less than 20 minutes in physical contact with its host, and it will not attempt to feed again until it has either completed a molt or, if an adult has thoroughly digested the meal.
Once feeding is complete, a bed bug will relocate to a place close to a known host, commonly in or near beds or couches in clusters of adults, juveniles, and eggs which entomologists call harborage areas or simply harborages to which the insect will return after future feedings by following chemical trails. Bed bugs use pheromones and kariomones to communicate regarding nesting locations, feeding and reproduction.

Chicago Tops Bed Bug Cities List for Third Year in a Row

ATLANTA, Jan. 21, 2015 /PRNewswire/ — Chicago tops the 2014 Bed Bug Cities List for the third year in a row. The list, released by pest control leader Orkin, ranks the cities by the number of bed bug treatments Orkin performed from January to December 2014. Bed bugs were in the news throughout 2014 in the Windy City, with reports of the blood-sucking insects on public transit and inside several downtown office buildings, as well as in police headquarters, a fire station, school, library and movie theater.
“Bed bugs are a serious issue across the country, and they’re very difficult to control,” said Orkin Entomologist and Technical Services Director Ron Harrison, Ph.D. “Bed bugs are not limited to any level of cleanliness or income, which means they can be found in any home or hotel. They’re great hitchhikers, and people often bring them inside on their clothes or in their luggage.”
Seven cities made double-digit jumps on Orkin’s Bed Bug Cities List compared to 2013, including Omaha, Neb. (+16),Lexington, Ky. (+16), Sacramento, Calif. (+14), Grand Rapids, Mich. (+13), Buffalo, N.Y. (+12), Charleston, W.Va. (+11) and Louisville, Ky. (+10). Several cities also dropped significantly in the past year, including Syracuse, N.Y., San Diego,Miami, Greenville, S.C. and Atlanta. Four cities made the Bed Bug Cities List for the first time including Myrtle Beach, S.C., St. Louis, Bowling Green, Ky. and Ft. Wayne, Ind.
The best product to combat the bed bug problem is Termirepel™, a product of C Tech Corporation.
Termirepel™ works by the mechanism of repellence by virtue of which it does not allow the insect/pest to come near the application and thus it negates the possibility of an infestation. Moreover it is available in the form of polymer compatible masterbatches as well as in lacquer form to be applied on wood and other furniture. Thus it is easy to apply and safe to use.
