The likelihood of bed bugs increases if the affected individual has been traveling, or if they have acquired used beds or furnishings before symptoms started to appear. Bed bugs also are suspect if you wake up with itchy welts you did not have when you went to sleep. It’s important to recognize, however, that not all bite-like reactions are due to bed bugs. Confirmation requires finding and identifying the bed bugs, shed skins, fecal spots, etc., which often requires the help of a professional. (Other possible sources of irritation that may be mistaken for bed bugs are discussed in University of Kentucky entomology fact sheet ENT-58, Invisible Itches: Insect and Non-Insect Causes). 


Both of these types of Hemiptera are sensitive to extreme temperatures. It may be necessary to rid the infestation by exposing the area to extreme heat or cold; they are most comfortable in temperatures around eighty degrees Fahrenheit. Raising the temperature to ninety-seven to ninety-nine degrees may kill off a significant portion of the population. 

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.
I paid $1200 for extermination heat treatment- lasted a few months and they are back- bought all new furniture! Still bugs- spray bye bye bugs spray which kills on contact but didn’t stop the infestation! This is going on 2 years now!!!! Mainly they are just in the 2 bedrooms. Ours and one that hardly no one sleeps in. But when grandkids come- they get bitten bad- I scrub, spray, vacuum & steam clean, & wash all bedding n still bit!!! Ready to burn the house down!!! HELP!!!!!! Can’t afford another $1200
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
Bring in only what is needed, and avoid sitting or placing coats and other items on beds, floors and sofas where the bugs commonly reside. Essential items can be placed on a tabletop or other hard surface, preferably away from bedrooms and sleeping areas. Better to sit on a hard (non-upholstered) chair than on sofas and recliners. Also try to avoid leaning or brushing against beds and upholstered furniture. If such items are carried out of infested dwellings (e.g., by sanitation workers or firefighters), it’s best to wrap them in plastic or at least not hold them against your body during transport. Emergency Medical (EMS) personnel may need to take additional precautions, such as removing a patient’s bed bug-infested shoes or clothing, or installing plastic sheeting before transporting them in the emergency vehicle.    

To use EcoRaider, the manufacturers recommend spraying all edges and seams of mattresses, as well as box springs, and bed frames. You can also use the spray to kill bed bugs from cushions, behind baseboards, edges of carpets, and moldings. It is safe for the whole household and won’t harm pets. You can get more information about EcoRaider and purchase it in Amazon here.
Just to be clear, you can kill bed bugs with heat. It’s just a matter of using the right equipment. A high-pressure steamer is the weapon of choice for killing bed bugs on contact, since their steam can surpass 200 degrees, and can penetrate deep into soft materials like mattresses and upholstered furniture. You can also use a steamer on more than just clothes or other fabrics; a steamer can kill bed bugs hiding along baseboards, floorboards, window sills, door frames, and the edges of the carpet.

When bed bugs are suspected, sleeping and resting places should be thoroughly inspected. Check all possible hiding places, mindful that bed bugs, especially the young nymphs and eggs, can fit into very tiny cracks and crevices. Don’t overlook places where pets rest, and where bats or birds have entered structures. In these instances, bat or bird bugs, not bed bugs, may be present. If bats or birds are a source of infestation, they should be excluded from the premises. Note that bats and most bird species are protected by law and should not be killed. Contact the Illinois Department of Natural Resources for guidelines on bat or bird exclusion and removal.
Inspection requires knowledge, dedication and time. At minimum an inspection should involve a detailed examination of mattresses, box springs and bed frames, as well as likely hiding places for bed bugs within 20 feet of beds and other places where residents may sleep or rest, e.g., on couches). Clutter-free space will be needed to allow furnishings to be moved and manipulated for inspection. In general, rooms with more furnishings will take more time to inspect.
Bed bug bites are caused primarily by two species of the insect Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in the wall.[2]
Waking up with bites might be the first indicator that you have a bed bug problem. Their bites are often arranged in lines or clusters on the face, neck, arms or hands. Where there are bed bugs in large numbers, you might smell a sweet, musty odor (from the bugs’ scent glands) or see rust-colored spots on your bedding or mattress caused by bed bug blood or excrement. If you look closely, you might see adult bed bugs themselves, usually in mattress folds or seams or on the wall behind the headboard. Bed bugs prefer to stay close to their food source and are typically found hiding out within 1 to 5 ft of infested beds or furniture.
To use EcoRaider, the manufacturers recommend spraying all edges and seams of mattresses, as well as box springs, and bed frames. You can also use the spray to kill bed bugs from cushions, behind baseboards, edges of carpets, and moldings. It is safe for the whole household and won’t harm pets.

Select and use insecticides safely. There are no magic sprays that kill bed bugs very well.  Most commercial insecticides will kill bed bugs if applied carefully and directly to the insects and their hiding places. An exception is “Bug bombs”, or aerosol foggers. Foggers are mostly ineffective in controlling bed bugs. Because bed bugs hide in crevices and voids where aerosols do not penetrate, they are able to avoid contact with these insecticides. Their use is not recommended. Some of the products you may find helpful include:
Items that cannot be placed in a washer or dryer can sometimes be de-infested by wrapping them in plastic and placing them outdoors in a hot, sunny location for at least a day (for example, on pavement or in a closed vehicle parked in the sun). Packing items loosely in garbage bags and elevating objects off the ground helps the heat permeate further, and will make it harder for bugs to find a cool place to hide. Monitoring with a thermometer is prudent to ensure that a temperature of at least 120°F is achieved wherever the bugs may be.

After the bugs developed resistance against many of the most powerful pesticides, such as DDT, exterminators had been increasingly relying on two chemicals—chlorfenapyr and bifenthrin. But until now, no one had looked at whether bed bugs were developing defenses against these chemicals too, says Ameya D. Gondhalekar, one of the study authors and a research assistant professor at the Center for Urban and Industrial Pest Management at the Department of Entomology at Purdue University.
The Diatomaceous Earth seems to kill them and centipedes. Didn’t even know I had those til I put powder down to prevent bed bugs and found one curled up dead. It dries them out and kills them. Works great! I’ve heard boric acid doesn’t work on bed bugs but I do know it works wonders on killing roaches. My sister had them in an apartment & boric acid wiped them out!
Start in the corners and along edges of an open wall.  With the card, see if you can dig things out of the cracks and crevices. Work your way along the cracks and crevices. For example, if you are checking a baseboard along the floor, see if you can get the card between the baseboard and the floor, as well as the top of the baseboard and the wall. If you have a bare tile or wood floor, consider using a damp cloth or map to wipe the floor.  Don’t use too much water as floors can be slippery.  Look for anything moving after you wipe the floor. If you have carpeted areas vacuum the clean area. See Vacuuming Items to Capture Bed Bugs.  Don’t forget to check pictures and other items on this wall.

Flea bites are caused by the parasitic insect, the flea. The most common species of flea in the US is the cat flea, Ctenocephalides felis. Signs and symptoms of flea bites in humans include itching, hives, a rash with bumps, red spots with a "halo," and swelling around the bite. Treatment for flea bites includes over-the-counter medicine and natural and home remedies to relieve and soothe itching and inflammation. The redness of a flea bite can last from a few hours to a several days.
To know it's bedbugs, it's important to find the bugs themselves. Look at bedsheets and mattresses for little spots of blood, rusty-looking stains (crushed bugs), or black dots (bugs' poop). You might see live bugs around the seams or tags of mattresses and box springs, or in cracks of bed frames and other furniture. They can even hide in books, carpet edges, and electrical outlets.
Often, bedbug bites are clustered along lines usually following arms and legs. Theories range from the idea that bedbugs are feeding along blood vessels to the idea that bedbugs remain with their bodies touching the bedding while they feed, and the bugs are left to feed only along lines where the skin is touching the bedding in just the right manner.

I have had one bite in threes which cleared up in days and an occasional acne looking sore on my but and arm. I have noted in my car lots of little bites but no marks. My son does not appear to have bites. once he had one on his back that cleared quickly. I really needs some help here as I am getting obsessive with cleaning and making my child change and bath. I have checked my cat for flees and bought her a flee collar as I am thinking the stinging bites I get in the day may be from flees but no itch or real marks. Help please.


Although most furnishings need not be discarded, in some cases this may be necessary. This is especially true of heavily infested beds, sofas and recliners where bugs and eggs often reside in hard-to-reach places. Consequently, pest control firms may recommend such items be discarded, especially when in poor condition. When infested items are discarded, bagging or wrapping them prevents dislodgement of bugs en route to the trash. 
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
Minimize its spread. First, notify your landlord if you rent in a building to control its spread to other units. Thoroughly vacuum any infested areas, including carpets and mattresses, and then empty the vacuum bag into a plastic bag, seal it, and throw it in the trash outside. If you can’t get the bed bugs out of your furniture, discard items in a responsible manner. To avoid someone else from salvaging infested furniture or mattreses, rip, remove stuffing, or spray paint with the words “bed bugs.”

While most of the bed bugs were wiped out by the chemicals, three groups continued to thrive after being treated with chlorfenapyr, and five groups were still kicking after being treated with bifenthrin. That means that while some bed bugs will respond to these chemicals, others won't—and it's likely that more and more bugs will become resistant over time.
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.
After bedbugs find a food source, they bite down with their mouths and inject anticoagulant and anesthetic compounds into the skin. Depending on the species, these parasites feed on the host blood via 1 of 2 mechanisms. Vessel feeders directly insert their mouthparts into superficial capillaries, whereas pool feeders damage the superficial tissue and feed on the accumulated blood. As bedbugs feed, their color may change as they swell with the host blood, as shown in this picture of a larval bedbug feeding on a volunteer host.

Turns out, C. lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The researchers, from Purdue University, found that three out of 10 bedbug populations collected in the field showed much less susceptibility to chlorfenapyr, and five of the 10 populations showed reduced susceptibility to bifenthrin, according to a post on Entomology Today. The scientists defined "reduced susceptibility" as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide.
