Bedbugs are highly resistant to many sprays. There are, however, certain sprays that may be able to kill bedbugs. Check with a professional exterminator about advice using sprays to try and remove the bedbugs yourself. Dead bedbugs usually won't move, may be arched back, or red in color. Ultimately, you may be better off replacing your mattress and bedding and fumigating your home to kill the bedbugs.
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.

Bed bug infestations have resurged since the 1980s for reasons that are not clear, but contributing factors may be complacency, increased resistance, bans on pesticides, and increased international travel. The U.S. National Pest Management Association reported a 71% increase in bed bug calls between 2000 and 2005. The number of reported incidents in New York City alone rose from 500 in 2004 to 10,000 in 2009. In 2013, Chicago was listed as the number 1 city in the United States with the worst bed bug infestation. As a result, the Chicago City Council passed a bed bug control ordinance to limit their spread. Additionally, bed bugs are reaching places in which they never established before, such as southern South America.
Specks of blood on bedding, mattresses, or upholstered furniture such as couches and headboards: Look carefully at your blankets, sheets, and mattress pads and then check the mattress and box spring. Are there specks of blood anywhere, especially near the seams? If so, there could be a bed bug infestation. You should also check for specks of blood on all upholstered furniture, including couches and headboards.
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.

Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective. An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them. This may include a domestic clothes drier for fabric or a commercial steamer. Bed bugs and their eggs will die on contact when exposed to surface temperatures above 180 °F (82 °C) and a steamer can reach well above 230 °F (110 °C). A study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 °C (122 °F) for more than 2 minutes. The study recommended maintaining temperatures of above 48 °C (118 °F) for more than 20 min to effectively kill all life stages of bed bugs, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter. This method is expensive and has caused fires. Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature. One expert recommends not trying to get rid of bed bugs exclusively on one's own.

Excessively scratching the itchy, bitten areas also may increase the chance of a secondary skin infection. Antiseptic creams or lotions can be used to ward off infection and antihistamines can be used to treat the itching. And an infestation can take a psychological toll on those affected: People whose homes have been infested with bedbugs may have trouble sleeping for fear of being bitten in the night. There are also public health, social and economic consequences; office buildings and schools often have to close if they are dealing with a bedbug infestation.
Bedbugs are a species of insect known as cimex lectularius (literallycimex is Latin for bug and lactularius is Latin for bed). There is a second common species of bedbugs known as cimex hemiptera. These are known as the tropical bedbugs, staying within 30 degrees of the equator. There are published reports, many without supporting evidence, that each of the common bedbug species has chemically different saliva. Some researchers, however, have found no difference in the reactions caused by each species.
A cloth and hot soapy water: Like the sticky tape, a cloth with hot water can be useful for capturing bed bugs. Have a bucket of water handy and as you wipe an area, check the surface of the cloth for bed bugs and then immerse the cloth in the bucket. Wring the cloth to remove excess water; you do not need to soak the surface that you are wiping. Also, check the area that you just wiped because heat may cause hungry bed bugs to move. The cloth is particularly effective when you find a cluster or group of bed bugs. Keep in mind that wet surfaces will reduce the effectiveness of sticky tape as a trapping method.
With the bed now fully isolated and elevated, bed bugs hiding elsewhere in the room won’t be able to feed on you or hide in your bed. You can also use the ClimbUps to monitor the changing population of bed bugs in your home. Hopefully, you will see less and less bugs appear in the traps as you go through the next steps. Now that you have created a safe haven in your bed, you can move on to treating the rest of the room.
