Should I worry about a tick bite? Ticks are parasites that feed on blood, and although their bites are harmless they can still transmit diseases, such as Lyme disease or Rocky Mountain spotted fever. Learn what ticks are and how to recognize the signs and symptoms of a bite. This MNT Knowledge Center article also explains how to prevent tick bites. Read now
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.
Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.
Diagnosing bed bug bites can be hard for medical professionals. We often hear of doctors assuming a variety of skin conditions before bed bugs – especially doctors who haven’t encountered patients with bed bug bites before. While there is no specific test to determine whether bites are from bed bugs there are tests that can show whether or not it’s an insect bite. This is useful for ruling out issues like eczema or allergic reactions, but not for determining that any specific insect bite is a bed bug. To be sure you’ll want to check for other signs of bed bug infestation, such as the bugs themselves, moltings, and the characteristic staining of their blood meal feces.
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
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.
I have been getting bit maybe once a week but the bite marks disappear within a hr and no longer itch I have not found the culprit and I have bed bugs climb up interceptors under my bed for almost 4 months and still don’t see anything do you have an idea what could be biting me the marks appear in a row of three sometimes just one bite on my arms and in my face but no where else im clueless
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.
The bites usually last about 7 days, even if they are treated correctly. However, if you have sensitive skin like myself, they can last a couple weeks or in my husbands case, they last only a few days. As mentioned, if you scratch the bites its going to make things worse and besides running the risk of a bacterial infection, they will also take longer to heal so keep your nails away from them!
Amazingly, these sneaky little bloodsuckers dine on you without waking you. You don't feel their stealthy bite because they inject a numbing agent into your body, along with an anticoagulant to keep your blood flowing as they suck. The first sign of bedbugs may be itchy, red bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites.
