Application entails treating all areas where the bugs are found or tend to hide or crawl. This takes considerable effort and follow-ups are usually needed. Companies typically treat seams, folds and crevices of bed components, chairs and sofas, but usually will not spray the entire sleeping surface or seating area. They also do not spray bed sheets, blankets or clothing, which instead should be hot washed or heated in a dryer. 
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. 

It’s not likely that you’ll kill all the bed bugs with a bed bug spray. That’s where a residual powder insecticide comes into play. It kills any bugs that wander through the powder. Some powders can kill bugs for many years if left undisturbed. Skip the open areas and spray the powder in those places where you think they’ll be traveling to and from, like near bed legs and under baseboard trim.


Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals.[4][16][17][18] Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light.[19] Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.[20]
Amazingly, these sneaky little bloodsuckers dine on you without waking you. You don't feel their stealthy bite because they inject a numbing agent into your body, along with an anticoagulant to keep your blood flowing as they suck. The first sign of bedbugs may be itchy, red bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites.
Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
Bedbugs do, however, have a unique bite pattern. Although some bites may appear alone, most bites occur in a row of three to five bites (termed "breakfast, lunch, and dinner") or in a cluster of red bumps (a rash called bedbug dermatitis). The bites often appear in a zig-zag formation, but may appear in a straight line if the bugs bite you in the morning.

Unlike cockroaches and flies that feed on filth, there is often no relationship between bed bugs and cleanliness. Since the bugs feed solely on blood, pristine dwellings can be as vulnerable to infestation as are places of squalor. That said, poverty and privation can lead to increased risk of bed bug problems, as can the inability to hire a professional exterminator.    
Bed bugs like to travel and are good hitchhikers. They will hide in suitcases, boxes and shoes to be near a food supply. They are elusive, nocturnal creatures. They can hide behind baseboards and in cracks, crevices, and folded areas of beds, bedding and adjacent furniture, especially mattresses and box springs. Bed bugs can also hide in electrical switchplates, picture frames, wallpaper and nearly anywhere inside a home, car, bus, or other shelter. Bed bugs usually come out at night for a blood meal. However, they are opportunistic insects and can take a blood meal during the day, especially in heavily-infested areas. Bed bugs usually require 5-10 minutes to engorge with blood. After feeding, they move to secluded places and hide for 5-10 days. During this time in the bed bug life cycle, they do not feed but instead digest their meal, mate, and lay eggs.
I work @ a hotel, and just found out that one of the rooms has a bed bug problem. I work at the front desk, and never go into the rooms. But i work third shift, and sleep in the chair in the lobby. Just wanted to know what my chances were of catching them? I will be going home and looking just to make sure. But since i work here, and its un-avoidable, what are some things i can do to protect myself from taking them home?
To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.

The journal Insects published a study on products containing essential oils for bed bug control. It was found that essential oils like cedar oil, cinnamon oil, clove oil, peppermint oil, rosemary oil, and lemongrass oil all have insecticidal properties against bed bug populations. The study concluded that using these essential oils in a bug spray can be an effective way to reduce bed bug populations without putting humans at risk of exposure to chemicals.8


I can definitely understand. This is has been going on with us for almost a year. My hands and arms look like I have leprocy or something. Horrible blisters, rash, scabs, and bunches of “bumps” especially in my right hand. I wind up with painful blood blisters some times. I am living on benedryl and calamine lotion. I hate going out because of what I look like. I have taken to using cover up and foundation on my hands to make the mess less noticable. i have a long-sleeved summer weight sweater that I wear whenever I do have to go out.

You’ll likely only see them in their hiding spots or crawling across the floor since, unlike other insects, bedbugs cannot fly or jump. Durham says to check along the edges of your mattress. You may see the exoskeletons that bedbugs have shed as they matured, or you may notice a musty smell, both of which indicate there could be bedbugs in the area. It can also be helpful to check your bed with a flashlight during the middle of the night (since these crawlers tend to be more active at night.)

As bed bugs grow they molt, shedding their skin five times before reaching maturity. A blood meal is needed between each successive molt. Adult females also must feed in order to lay eggs. Under favorable conditions (70-80°F), the bugs can mature fully in as little as a month, producing multiple generations per year. Cooler temperatures or limited access to blood prolong the development time. 


Insecticides are an effective way to eradicate bed bugs, but not the only way. If you or someone in your house is highly sensitive to chemicals, or you’re just not crazy about the idea of spraying chemicals where you sleep, kill the little blood suckers with heat. Temperatures above 120 degrees F kill all stages of bed bugs. Steamers can be used to treat all the same areas where you would have sprayed contact killers. Steamers like the one shown at (top) cost about $150 and are good for many other projects like removing wallpaper, cleaning tile, removing labels, cleaning engine parts and removing wrinkles from fabric.

Reactions to bed bug bites vary among individuals. Many persons show no signs of bites. Others don’t realize they’ve been bitten until redness and swelling appear around the bite, sometimes with intense itching. Some exhibit inflamed swollen spots that may occur in linear series or have a rash-like appearance. Such bite marks, when they appear, may not show for several days after the person is bitten.

Heat chambers like this one (bottom) can be used to heat personal belongings and kill any hidden bed bugs without chemicals. They come in various sizes, and prices start at less than $200. In the summer, you could let Mother Nature do the dirty work. Bag up your belongings and set them on the driveway. On a day when the temp tops 95 degrees, a bag placed in the sun should easily reach 120 degrees F inside.


Bed bug eradication is challenging and it’s prudent to hire a professional when resources allow. However treatment can be expensive, often costing hundreds or thousands of dollars. Those who cannot afford this often must cope with the problem themselves. A useful step that anyone can take to combat bed bugs is to install bed encasements. Covering the mattress and box spring can help eliminate a substantial portion of the bed bug population -- especially if discovered early while most of the bugs are still confined to the bed area. Extra care should be taken when installing budget encasements since these can tear easily, especially on metal bed frames. Ideally both the mattress and box spring should be encased. If only one encasement is possible it’s often best to cover the box spring which is harder to subsequently inspect.
Bed bugs tend to live in clusters similar to German cockroaches. Adult bed bugs generally travel 15 to 20 feet, or less, from their harborage sites. Common bed bugs feed on human blood just below the surface of the skin with their piercing-sucking mouthparts. Those bitten by a bed bug may develop small, white to red, hard welts at the bite site. These bites itch intensely.

First up is the most commonly recommended tool by far: rubbing alcohol diluted in water. This is suggested because alcohol can kill bed bugs on contact, and evaporates shortly after, so it’s considered safe for use pretty much anywhere in a home. A recurring theme in these recommendations are household items that are considered to be safer for people than mainstream chemicals.
Many news reports in recent years have focused on the discovery of bedbugs and their health effects (even in upscale five-star hotels), and a number of lawsuits have been filed by guests of fashionable hotels who awoke to find hundreds of bedbug bites covering their skin. Searching on travel-review web sites regularly reveals information and even photos confirming the presence of bedbugs in numerous hotels.
Other types of bed bug traps include those that do not rely on humans as bait, but instead use CO2and/or other attractants. CO2 is thus far the most powerful lure for bed bugs, as it is the primary cue they follow to locate hosts. Traps that issue CO2 for a period of time are more expensive than Climbup™ traps, but can effectively trap bed bugs when no host is present, such as in common areas, vacant homes or units, offices, schools, and theaters. Thus they can help confirm infestation and eradication.
It takes time and persistence to get rid of bed bugs, and in some cases, the cooperation of landlords, neighbors and others. It can be physically and emotionally exhausting. It can also be expensive when pest control companies are called in. Just remember - bed bugs are more of a nuisance than a health concern and, with vigilance, you can avoid or deal with infestations.
Once the mattress and box spring are dry, encase them in sealed bed bug encasements. Encasements are crucial, as they prevent bed bugs from entering or escaping the mattress and box spring, cutting off key hiding places. Remember to leave the encasements on for at least 18 months to ensure that any bed bugs already inside have starved to death. Once the encasements have been applied, you can put your mattress and box springs back on your treated bed frame, and put your laundered bedding back on your bed.
