Very helpful article, plus everyone’s comments. I wish you all the best of luck with bedbug problems. We went to a cabin near Yosemite before Christmas and I saw bugs on the bed. Luckily we didn’t sleep there and left right away. However I’m afraid some came home with us. About 3 weeks after our trip, I got a rash on my neck, but it’s not very itchy. Haven’t seen any bugs at home, but am worried. Will try the tips in the article–any suggestions how to heat a bedroom to 120 degrees?
Chances are, you or someone you know has had a run-in with bed bugs. It might have happened in a scrupulously clean bedroom. Or maybe it was a hotel room, office or college dorm. In the February issue of Scientific American entomologist Kenneth Haynes of the University of Kentucky explains how, after a lengthy absence, bed bugs are staging a comeback. The good news is scientists are intensively studying these insects, and their insights suggest novel ways of detecting the bugs and eradicating infestations. Some of those potential solutions are a long way off, however. In the meantime the best bet is to avoid bringing bed bugs home in the first place. I called Haynes to ask him how to do that and what to do if one suspects an infestation (eek!), among a bunch of other practical-minded questions.
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building. 
Apply as a coarse, low-pressure spray to harborage areas including crevices, baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and to bedsprings and bed frames. After removal of bed linens, apply Transport Mikron to mattress and boxsprings. Apply to tufts, edges, seams and folds (do not spray clothes or bed linens). Your may apply it to furniture, but not to areas where there is direct access to seating or arm placements. Infested bed linens should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperatures.
Vigilant travelers may also want to elevate suitcases off the floor on a stand, tabletop or other hard surface rather than storing them on the floor or another bed. Hyper-vigilant travelers may further opt to keep belongings in sealed plastic pouches and their suitcase in a zippered tote — however each traveler must decide how cautious they wish to be. 
My husband for 5 yrs had been getting bites on one knee and on his stomach about every other month or so. They are maybe 3 or 4 on stomach area and maybe 6 or 7 on the knee – always same knee and same area on stomach. We wondered about bed bugs so we put DE out, corked all openings and cracks, and sprayed – we have never seen signs of the bed bugs, we put the mattress and box springs in the bed bug proof cover. If it were bed bugs would they not bite some where else and would you not get more of them after all this time? The only bug we have seen are the ones that look like lady bugs sometimes but I understand they do not bite!
A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific.[5] Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects.[4] If the number in a house is large a pungent sweet odor may be described.[4] There are specially trained dogs that can detect this smell.[2]
One trick to make this disposal easier involves using the cut-off end of a nylon stocking (or a knee-high nylon stocking) and a rubber band. Insert the stocking (toe first) into the end of the vacuum suction wand/tube, leaving the opening of the stocking protruding out of the end of the suction wand. Then fold the stocking opening back over the end of the wand and use the rubber band to secure it there. When the vacuum is turned on and the bed bugs are sucked into the tube, they will be trapped in the stocking. Afterwards, carefully remove the rubber band and retrieve the bug-filled stocking. Then secure the end of the stocking with the rubber band and dispose of it. 
To prevent bringing bed bugs to one's own home, travelers are advised to take precautions after visiting an infested site: generally, these include checking shoes on leaving the site, changing clothes in a garage before returning to their home, and putting the used clothes in a clothes dryer outside the house. When visiting a new lodging, it is advised to check the bed before taking suitcases into the sleeping area and putting the suitcase on a raised stand to make bedbugs less able to crawl in. "An extreme measure would be putting the suitcase in the tub." Clothes should be hung up or left in the suitcase, and never left on the floor. [29] The founder of a company dedicated to bedbug extermination said that 5% of hotel rooms he books into were infested. He advised people never to sit down on public transport; check office chairs, plane seats and hotel mattresses, and monitor and vacuum home beds once a month.[30]
The bites do not usually require medical treatment. Secondary bacterial infection of the skin may develop in areas that become irritated due to prolonged scratching. Topical antibiotic creams or ointments may relieve symptoms of a secondary infection. Antiseptic lotions may also be beneficial. If you've had an allergic reaction to the bedbug bites, your doctor may recommend oral antihistamine medications or corticosteroids.

Encasing mattresses is one of many good parts of a solution, but it doesn't get rid of the infestation. There are going to be other bugs away from the mattress, hiding nearby. What mattress covers are good at is entombing the sometimes large number of bed bugs that can live on a mattress. And because the covers tend to be uniform in color and don't have a lot of seams that the bugs can hide in, it's easier to see the insects.
However, another thing which has helped me with the intense itching is a regular hair brush! I was scratching so much that I grabbed the hair brush and used that to cover more territory! I have found that even if I “brush” intensely, it will not bleed and slowly the itching will subside. I have also heard of a quirky aid in “bug direction”…..used dryer sheets will discourage bugs from the area….what I saw was the sheets tucked in between the mattress and box spring by each bedpost.

Bed bugs are an increasing cause for litigation.[69] Courts have, in some cases, exacted large punitive damage judgments on some hotels.[70][71][72] Many of New York City's Upper East Side home owners have been afflicted, but they tend to be silent publicly in order not to ruin their property values and be seen as suffering a blight typically associated with the lower classes.[73]

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. 
Although treating bedbug bites isn't difficult, actually getting rid of the bedbugs is another story. A professional exterminator can help. You will need to discard infested mattresses, box springs, and pillows. You can heat treat or cold treat items such as clothing by laundering or freezing. However, the room itself will need to be treated to eliminate bedbugs that can live in cracks in walls, floors, and furniture.
As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, they’re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.
