Bed bugs are obligatory bloodsucking. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
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.
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. The National Institutes of Health recommend about 7-9 hours of sleep each night for older, school-aged children, teens, and most average adults; 10-12 for preschool-aged children; and 16-18 hours for newborns. There are two stages of sleep; 1) REM sleep (rapid-eye movement), and 2) NREM sleep (non-rapid-eye movement). The side effects of lack of sleep or insomnia include:
Wearing an insect repellent is not completely effective, although you might try oil of lemon eucalyptus or DEET to prevent bites. Avoid bringing home second-hand items such as used furniture, mattresses, or any item that someone has kept in a bedroom. Unfortunately, bedbugs can linger in items for a year without feeding. Launder all used clothing before storing or wearing it. Use mattress, box spring, and pillow encasements on your bed. Fill in any cracks and crevices in your bedroom.
Bed bugs usually bite people at night while they are sleeping. Hungry bed bugs may also feed during the daytime, especially if this is when the occupant normally sleeps. They feed by piercing the skin with an elongated beak through which they withdraw blood. Engorgement of the bed bug takes roughly three to 10 minutes, but because the bite is painless, the person seldom realizes they are being bitten. Bed bugs normally do not reside on people like head or body lice do; instead, immediately after feeding, bed bugs crawl to a secluded location to digest their meal. Symptoms after being bitten by bed bugs vary from person to person. Many develop an itchy red welt within a day or so of the bite. Others have little or no reaction. Sometimes the reaction is delayed days or even weeks after the actual bite occurs, which can make it difficult to determine where or when bites actually occurred. Studies conducted in bed bug-infested apartments suggest about 30 percent of people do not react even when bitten repeatedly over time, and there is still higher incidence of non-reactivity among the elderly. Unlike flea bites, which occur mainly around the lower legs and ankles, bed bugs feed on any skin exposed while sleeping (face, neck, shoulders, back, arms, legs, etc.). The welts and itching are often wrongly attributed to other causes, such as mosquitoes. For these reasons, infestations may go a long time unnoticed, and can become quite large before being detected.
Zonalon and Prudoxin (doxepin) are topical creams that can be prescribed for relief from itching. The active ingredient in these products is a topical tricyclic antidepressant and seems to work against itching by reducing histamine. Histamines are chemicals your body produces in response to injury or when having an allergic reaction. A prescription-strength cortisone cream may also help. In some cases, a prescription antihistamine will be given.
Hey I went to visit friends this Saturday and Sunday. Saturday I slept fine Sunday I slept in a different location, I kept feeling bites but was unsure through the night. I woke up the next morning with red bumbs like two clusters of three and four on one arm, four on my other arm not far apart, four on my leg, three on my lower back. As they day went by they got bigger like lumps and really itchy, I had benedryl and creme I could not sleep last night at all. Some of them hurt a bit I try not to scratch them. Ooh and three on my face, my skin is very sensitive, my friends sat on the same chair I sleep on noone got bit. How long does the itching last, Iaautomatically knew it had to be bed bugs does it sound like them??
Cutaneous reactions to bedbug bites can vary widely and are easily confused with other conditions (Table 1).15–19 A typical lesion is a 2- to 20-mm, pruritic, erythematous maculopapule with a central hemorrhagic crust or vesicle.5,8 Macules, papules, wheals (Figure 3), vesicles, bullae, and nodules have all been reported,20 as have asymptomatic lesions with a barely visible punctum as the only evidence of a bite.8 Bites vary in number and are preferentially distributed in unclothed areas (e.g., face, neck, extremities). Unlike many other arthropod and insect bites, bedbug bites are rarely located in the popliteal fossae or axillae.21 Lesions can be noticeable immediately when waking up or several days later, with the reaction often progressing from delayed to immediate with subsequent exposures22–26 (Table 2). The classic bedbug rash is referred to as “breakfast, lunch, and dinner” because it commonly presents as several bites in a row or cluster 20 (Figure 4).
Bed bugs are a growing problem in schools and daycares. Typically they are introduced by students or staff living with an infestation at home. Pinpointing where the bugs exist can be challenging in such environments since there are no beds or sleeping areas for the insects to congregate. (Similar challenges occur when bed bugs are found in offices, libraries and retail stores.) Usually only small numbers of bed bugs are spotted, often on a student’s clothing, backpack, chair or desk. While this does not necessarily confirm that the child’s residence also has bed bugs, the parents should be notified that the home should be inspected, preferably by a professional. Teachers, nurses, and staff should be educated about the bugs and what they look like. Bed bugs should also be considered if a student frequently has reddened itchy welts --but keep in mind such reactions can be for reasons other than bed bugs.
One thing I’ve noticed is my cat is unaffected by all this. I’m assuming I’m the tastier option of the two but I’m not discounting the fact she may be spreading eggs around my apartment. she has been carefully inspected from tip to tail with a nit brush and she has no bites, isn’t scratching and seems to be just as snug as a bug in a rug. To be precautionary I am going to begin dusting her with flea powder in the morning when i go buy some.
Summer means more time outdoors–and more opportunity for annoying critters to bite you. Most of the time, all you’ll get is a little red bump with itching and maybe a little swelling. These insect bite symptoms can be treated easily with anti-itch creams and over-the-counter antihistamines. Occasionally, bites can cause allergic reactions that lead to severe swelling and shortness of breath; if that happens to you this season, you need to be seen by a doctor.
Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.
