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.

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.

Alcohol will kill bed bugs but not their eggs and will need to be used often to control infestation. It is not an effective way to get rid of bed bugs permanently. If you want to use this bed bug treatment you need to mix nine parts 91 percent isopropyl (rubbing) alcohol with one part water. Place the solution in a chemical sprayer to cover large areas. Use a spray bottle for small areas and to get into crevices. Spray all areas including head/foot boards, hard surfaces, base boards, door jams and any other bed bug hiding spots.

First up are the contact sprays, like STERI-FAB and JT Eaton Kills Bed Bugs. These will kill quickly, but evaporate shortly after, leaving no long-lasting protection. Spray along baseboards, below drawers and on drawer slides, behind cabinets, and behind night stands. Follow up with a residual spray, such as Bedlam Plus and JT Eaton Kills Bed Bugs Plus. Residual sprays will offer long-lasting protection against bed bugs and hatchlings. Bedlam Plus is ideal for cracks and crevices throughout the room, while JT Eaton Plus can be used below the cushions and bases of sofas, chairs, edges of carpets and other fabric items.
Research has shown that some bed bugs are resistant to the pyrethroid pesticides that have been most commonly used in recent years by pest management professionals. Likewise, pyrethroids such as deltamethrin and permethrin have been among the active ingredients most commonly available in pesticides at retail stores. The ongoing use of pyrethroids has undoubtedly contributed to the resistance we see today in some bed bug populations.

According to a study carried out on Ortho Home Defense, it contains a chemical bifenthrin that is considered relatively safe and kills off bugs that pyrethroid-based insecticides can’t. It is also effective against bed bug eggs and larvae.12 It should be sprayed as a spot treatment in any crevice where bed bugs can reside.

We recommend spraying Steri-Fab in areas where live bed bugs are visible. Steri-Fab combines a synthetic pyrethroid insecticide and isopropyl alcohol to kill bed bugs fast on contact. Steri-Fab also acts as a sanitizer. Steri-Fab does not leave any residual, meaning it can be applied virtually anywhere. Simply shake well, then apply to desired treatment areas. Insect mortality is imminent, generally within 10 minutes of spraying.
Bedbug bites can lead to anxiety, sleeplessness and even secondary infections, but there have been no reported cases of bedbugs transmitting disease to humans. They do, however, harbor human pathogens: At least 27 viruses, bacteria, protozoa and more have been found in bedbugs, although these microbes do not reproduce or multiply within the insects. Canadian researchers announced (pdf) in the June issue of Emerging Infectious Diseases that bedbugs isolated from three individuals in a Vancouver hospital carried methicillin-resistant Staphylococcus aureus, aka MRSA. Still, there have been no reported cases that the bugs actually transmit human disease.
Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective.[3][6] An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them.[6] 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).[31][15] 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.[32] This method is expensive and has caused fires.[6][15] Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature.[6] One expert recommends not trying to get rid of bed bugs exclusively on one's own.[29]
A hair dryer might seem like a safer way to kill bed bugs with heat. Unfortunately, their maximum temperature is rarely more than 150 degrees. That heat level can kill bed bugs, but only if you maintain the heat over them for several minutes. So unless you want to follow each bug you see around with a hair dryer until they eventually die, you’d probably be better off just hitting them with the thing.

Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] These insects feed exclusively on blood and may survive a year without eating.[3] Adult Cimex are light brown to reddish-brown, flat, oval, and have no hind wings. The front wings are vestigial and reduced to pad-like structures. Adults grow to 4–5 mm (0.16–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide.
Bedbug bites, like all insect bites, can become infected through excessive scratching, as underneath the fingernails lies a host of bacterial pathogens. If your bites become infected, they will appear red and swollen, feel tender and may drain pus. Typically there will not be a fever unless a substantial area of the skin is involved. If you experience any of these symptoms, you must seek medical attention as it points to a secondary infection. Your physician may prescribe antibiotic therapy or, if the infection is mild, an antiseptic medication that you can buy without a prescription.[12][13][14]

Bedbugs normally feed at night, usually approximately 1 hour before dawn. However, if the conditions are favorable, they also feed during the day. Feeding takes 3-12 minutes. In proper conditions, adult bedbugs can survive without a meal for 1 year or longer. Each female lays approximately 300 eggs in her lifetime. The eggs hatch in 10 days. The nymph stage lasts 6 weeks, undergoing 5 molts.

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.
