Reports of bedbugs can be found in the popular press and on hotel and travel review sites, and they appear to be making a comeback. The good news is that they typically do not pose serious health risks, even though their bites may be uncomfortable. These slides show you how to recognize bedbugs, know where they're hiding, and learn what to do to prevent getting bitten.
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
Individual responses to bites vary, ranging from no visible effect (in about 20–70%), to small macular spots, to prominent wheals and bullae formations along with intense itching that may last several days. The bites often occur in a line. A central spot of bleeding may also occur due to the release of anticoagulants in the bug's saliva.
Adult bed bugs are about 3/16” long and reddish-brown, with oval-shaped, flattened bodies. They are sometimes mistaken for ticks, cockroaches, carpet beetles or other household insects. The immature bed bugs (nymphs) resemble the adults, but are smaller and lighter in color. Bed bugs do not fly, and they don’t jump like fleas do ― but they can crawl rapidly over floors, walls, ceilings and other surfaces. Adult females lay their eggs in secluded places, depositing 1, 2 or more eggs per day, potentially hundreds during their lifetime. The eggs are tiny (about the size of a dust spec), whitish and hard to see without magnification, especially on light-colored surfaces. When first laid, the eggs are sticky, causing them to adhere to surfaces. At room temperatures, bed bug eggs hatch in about a week. Newly emerged nymphs are straw-colored and no bigger than a pinhead.
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.
How to treat and prevent chigger bites A chigger is a form of mite that feeds on human skin cells. Although they are so small that the naked eye cannot see them, chiggers can inflict extremely itchy bites that can last up to a week without treatment. Here we look at how to avoid getting bitten as well as how to recognize and treat any existing bites. Read now
The diagnosis of a bedbug infestation should be based on the clinical history and appearance of bites. A thorough inspection of sleeping quarters by the patient, a family member, or a pest control expert may demonstrate the telltale signs of an infestation15 (i.e., specks of blood-tinged insect feces and exoskeleton casts [Figure 5]). With the aid of a magnifying glass, special attention should be given to cracks and crevices of furniture, baseboards, electrical boxes, curtains, carpet, luggage, bed frames and headboards, picture frames, wall hangings, mattress and box spring seams, peeling wall paper, clothes, and linens.37 Live bedbugs can sometimes be caught by turning on a flashlight just before dawn, when bedbugs are most active, larger in appearance, and slower to scatter because of recent feeding.40
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??
One trick to make this disposal easier involves using the cut-off end of a nylon stocking (or a knee-high nylon stocking) and a rubber band. Insert the stocking (toe first) into the end of the vacuum suction wand/tube, leaving the opening of the stocking protruding out of the end of the suction wand. Then fold the stocking opening back over the end of the wand and use the rubber band to secure it there. When the vacuum is turned on and the bed bugs are sucked into the tube, they will be trapped in the stocking. Afterwards, carefully remove the rubber band and retrieve the bug-filled stocking. Then secure the end of the stocking with the rubber band and dispose of it.
This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area). The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.
These blood suckers lock on to the carbon dioxide (CO2) release when sleeping. Once they have you, they head toward a warm part of your body and begin to bite. Two tubes are inserted into your body; one is used to inject a mixture of anticoagulant and anesthetic while the other is used to suck up your blood. You never notice the bites until you wake up and realize you were the main course!
Bed bugs are very resilient. Nymphs and adults can persist months without feeding which is unusual for most insects. The ability to survive without a blood meal is longer at cooler temperatures ― potentially up to a year or longer at 55°F or less. In temperature-controlled buildings, a more typical duration is about 2 to 6 months. Consequently, it is usually impractical to leave buildings unoccupied in hopes of ‘starving out’ an infestation. When infested dwellings such as apartments are vacated, bed bugs often disperse to nearby units, or reduce their activity until the unit is reoccupied.
Don't assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It's best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.
