Bloodsuckers on the Comeback
Though rare in recent years, but on the rise for the last 10 years, the bed bug, Cimex lecturalius of the family Cimicidae (which includes the similar bat and bird bugs) once infected a third of 1930's London bedrooms, and every American had probably been bitten before the use of insecticides after World War II. This denizen especially of low income housing, homeless shelters, camp sites, and jails prefers human blood over its other animal sources. There is a tropical species, which you might encounter while visiting the alligators or Disney World in Florida, Cimex hemipterus that feeds on people, birds and bats.
Where, Why, When
They can be a persistent pest as they can survive without food (blood) for six months fooling naive returning or visiting summer cabin inhabitants or any empty dwelling. They came to America just as the colonists did, by ship, and now they can travel by infested trains, buses, and airplanes. They love hiding and living in the dark cracks near or even in any nooks and crannies away from the mattress. The babies, the nymphs, only feed on you for a couple of minutes, but when they grow up they can have a feast for maybe quarter of an hour. Eight out of ten are going to get a itchy bump, and the odds are great there will be multiple bites as well. You will only probably be able to see the little critters after they turn dark bloody red-brown because they are pale while waiting for you to set their table.
Determining if One Has this Problem
Fortunately you can be alerted to an area with a large colony because their multiplied scent glands will allow you to smell the sickly-sweet, musky raspberry aroma. Look closely at the bedding, see their waste products stain dark brown, the skin sheddings of the larvae that will be left, and blood stains.
You might have to do a ransack of a bedroom, however to really find them as they are better hiding than Osama Ben Laden. Looking very closely at the mattress, especially seams and buttons, box spring, and bed frame. Looking around the woodwork, holes in walls, switch and wall socket plates, around windows, and all through the furniture, pulling drawers out, and most importantly any rug.
Now, after determining you have the problem, now clean, vacuum and spread bed bug applicable pesticide on everything except the pillow, blanket or sheet (laundry should suffice). Allow the bedding to dry, then use mattress covers. Keeping attics or basements, even vents and air conditioners clean of nests and then dusting helps in the similar process of ridding oneself of the cousin bat and bird bugs.
The Comeback Kids
Reports from pest control contractors or operators (PCO's) show an increase in complaints concerning bed bugs. My guess is some poison tolerance and perhaps laxity in hygiene has caused some resurgence.
Obviously Mick Jagger and the Rolling Stones had experience with them in New York as it is cited as a place where one finds the "...bed bugs uptown..." in Shattered.
Note: They're back! --again, in the news and in your bedrooms (as of April 2009)
