Hi! I was just curious, I am staying at my parents (which Ive never had an issue before) and have 21 bites on my bicep/forearm/in the bend of my arm which I noticed yesterday. They dont itch and are already losing the redness. This morning I woke up and have no new bites. My husband and son do not have bites either (they both are very sensitive to insect bites too). We checked the bed before bed last night and there were no signs of bed bugs. Is it possible that its still bed bugs???
In most infestations, consultation with a professional exterminator is advised because elimination is more likely to be effective if multiple pest management methods are used. These include monitoring devices, canine detection, clutter removal, vacuuming, heat or cold treatment, sealing cracks and crevices, and judicious use of nonchemical and chemical pesticides. Monitoring devices include moat-like devices (e.g., Climbup Insect Interceptor) that trap bedbugs ascending and descending furniture legs, and emitting devices that use carbon dioxide, heat, and/or chemicals (e.g., Nightwatch monitor) that attract and trap bedbugs. Specially trained dogs are reported to detect bedbugs with 97 percent accuracy and are able to differentiate live bedbugs and viable eggs from debris remaining from previous infestations.41 Vacuuming is a highly effective method for removing bedbugs, but not eggs because these adhere to surfaces.42 High-efficiency particulate air filters eliminate bedbug allergens and debris.42 Nonchemical treatments include petroleum jelly (which can be applied to legs of furniture to prevent bedbugs from ascending), heating, and freezing (see Table 36 for effective killing temperatures).
Bedbug bites typically are stealthy and not felt by the host. This is because they inject a numbing substance into the skin along with an anticoagulant agent to prevent blood from clotting at the feeding site. Itchy, red bites on the skin may be the first sign you've been bitten. Bites are most common on the arms and shoulders, and the bites often occur in straight rows, as pictured here.
A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific. Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects. If the number in a house is large a pungent sweet odor may be described. There are specially trained dogs that can detect this smell.
With practice and a flashlight, nonprofessionals can become proficient in finding and destroying bed bugs. The process is made easier by reducing clutter, especially in bedrooms and sleeping areas. Bugs that are spotted can be removed with a vacuum (see previous discussion), or killed with over-the-counter insecticides labeled for such use. Most bed bug sprays intended for householders have little remaining effect after the spray has dried. Therefore it’s important to initially contact as many of the insects as possible with the spray droplets. Insecticide labels should be read carefully as some bed bug products should not be used on mattresses and seating areas. Some insecticides applied as powders or dusts (e.g., diatomaceous earth) will kill bed bugs although boric acid powder will not. However powders can be messy and difficult to apply, especially by nonprofessionals. Total release foggers (otherwise known as ‘bug bombs’) are ineffective against bed bugs and potentially dangerous when used incorrectly (see University of Kentucky entomology fact sheet Limitations of Home Insect Foggers).
As mentioned earlier, applying insect repellent at bedtime will probably not deter bed bugs from biting. When working in severely infested dwellings, there may be some benefit to spraying tops and bottoms of shoes with DEET-based repellents. Those working in bed bug-infested environments may also want to hot wash or run clothing, etc. through a dryer upon returning home or to the office.
Never treat any bedding, mattress, etc. with anything other than the treatments listed: borax, enzyme cleaner, Comet, sodium borate. Other pesticides and exterminating fluids can be harmful to humans. Even so, bedding and mattresses treated with chemicals such as borax or Comet should be left outside to dry naturally in the sun, then wrapped in plastic before next use, so as not to irritate the skin.
Bedbugs can live in any area of the home and use tiny cracks in furniture as well as on textiles and upholstered furniture as hiding places. They tend to be most common in areas where people sleep and generally concentrate in beds, including mattresses or mattress covers, box springs, and bed frames. They do not infest the sleeping surfaces of beds as commonly as cracks and crevices associated with the bed frame and mattress. Other sites where bedbugs often reside include curtains, edges of carpet, corners inside dressers and other furniture, cracks in wallpaper (particularly near the bed), and inside the spaces of wicker furniture.
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.
Avoiding bed bugs is most challenging in hotels, apartment buildings, and other places where there are many people, high turnover and ongoing opportunities for introduction of the pests. Periodic, preventive inspection by tenants, housekeeping/maintenance staff, or pest control firms is the best way to detect infestations in their initial stages when they are easiest to control. Visual inspections can be supplemented by using various monitoring devices to capture and reveal bed bugs that may have been overlooked by occupants.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
