10 Myths and Misconceptions About Bedbugs

10 Myths and Misconceptions About Bedbugs There are many misconceptions about the humble bedbug. Bedbugs (or cimicids) belong to a highly specialized family of insects that feed off the blood of humans, bats, and birds. The best-known members are the temperate-climate parasite Cimex lectularius (which means bedbug in Latin) and Cimex hemipterus, a tropical version. Bedbugs are the most widely recognized insect in the world. They are known to have fed on humans for more than 4,000 years- and probably much longer. Unfortunately, there are many myths about these tiny pests. If You Wake Up With Insect Bites, You Have Bedbugs Bedbugs tend to bite on locations that are exposed during sleep- the arms, legs, and back as well as the face and eyes. The insects prefer sites that lack hair, with a thin epidermis that provides access to plentiful blood. However, bedbugs are not the only nocturnal feeder on humans. Quite a few other arthropods could be the cause of bite marks, including fleas, mites, spiders, or even bat bugs. Also, many medical conditions cause rashes that look similar to bug bites. If the marks persist but you dont find signs of an infestation, consider a trip to the doctor. Are you the only one in your household waking up with bites? People react to bedbug bites differently, just as they do with mosquito and other insect bites. Two people can sleep on the same bedbug-infested mattress, and one will wake up without any signs of being bitten while the other will be covered in bite marks. Bedbugs Cannot Be Seen by the Naked Eye While bedbugs are pretty small insects, they arent microscopic. If you know where to look for them, you can definitely see them without the aid of a magnifier. The bedbug nymph is roughly the size of a poppy seed. Adults measure a bit larger than 1/8th of an inch, or about the size of an apple seed or a lentil. The eggs, which are just the size of a pinhead, are harder to see without magnification. Bedbug Infestations Are Rare Although bedbugs all but disappeared in developed countries in the 1930s and again in the 1980s, global bedbug infestations are increasing in the 21st century. Rises in bedbug activity have been seen on every continent except Antarctica. In the United States, bedbugs are reported in all 50 states, and an estimated one in five Americans either has had a bedbug infestation in their home or knows someone who has. Today, infestations are found in offices and retail environments, in health and transportation buildings, and even in movie houses: basically, anywhere people sleep or sit. Bedbugs Are a Sign of a Dirty House Although there is a great social stigma to having a bedbug infestation, bedbugs dont care how neat and tidy your house is, nor do they care if youre the best housekeeper on the block. As long as you have blood pumping through your veins, bedbugs will happily take up residence in your home. The same rule holds true for hotels and resorts. Whether a hotel has bedbugs has nothing to do with how clean or dirty the establishment is. Even a five-star resort can host bedbugs. One thing to keep in mind, however, is that clutter can make it much more difficult to get rid of bedbugs once theyre in your home- the mess gives the insects plenty of places to hide. Bedbugs Only Bite After Dark While bedbugs prefer to do their dirty work under cover of darkness, the light wont stop a hungry bedbug from biting you. In desperation, some people will try leaving all their lights on at night, hoping the bedbugs will stay hidden like cockroaches. All this will do is make you more sleep-deprived. Bedbugs spend most of their time hidden away. They only come out to feed once every three to seven days, usually from one to five a.m. They fully engorge themselves on your blood in 10 to 20 minutes, and then they go back to their hiding places to digest their food. After a meal, adult bedbugs may increase in length by 30 to 50 percent and in weight by 150 to 200 percent. Bedbugs Live in Mattresses Bedbugs do hide in the seams and crevices of your mattress. Since these nocturnal insects feed on your blood, it is to their advantage to live close to the place where you spend the night. But that doesnt mean bedbugs only live in mattresses. The insects also inhabit carpets and couches, dressers and closets, and even places where youd never think to look, such as inside picture frames and switch plate covers. Infestations can be extremely costly, resulting in multimillion-dollar damage in the hospitality industry, poultry industry, and private and communal households. Costs include payment for pest control, damage to social reputation, and replacement of infested clothing and furniture. You Can Feel a Bedbug Bite Bedbug saliva contains a substance that serves as a mild anesthetic, so when one bites you, it actually does you the favor of numbing your skin first. Its very unlikely that youd ever feel a bedbug bite when it happens. Reactions to bites vary from individual to individual. Some people have no reactions at all; often the bites start out as small indistinct lesions about two-tenths of an inch in diameter, which may develop into larger circular or ovoid welts. Some may grow as big as 2.5 inches in diameter. If there are a large number of bites, they can give the appearance of a generalized rash. They itch intensely, cause sleep deprivation, and can be associated with secondary bacterial infections as a consequence of scratching. Bedbugs Jump From the Floor to Your Bed Bedbugs arent built  for jumping. They simply dont have the legs for it as fleas and grasshoppers do. Bedbugs dont have wings, either, so they cant fly. They can only crawl for locomotion, so moving from the floor to the bed requires them to climb up a leg of the bed, or to scale belongings or furniture youve placed nearby. This can work to your advantage if youre battling bedbugs, as you can create barriers to keep them from climbing onto your bed. Cover the bed legs in double-sided tape, or place them in trays of water. Of course, if your bedspread touches the floor, the bedbugs will still be able to climb up, and the insects have also been known to crawl up the wall to the ceiling and then drop onto the bed. Bedbugs Transmit Diseases to People Although bedbugs can and do carry infectious diseases, there is little danger of the viruses being transmitted to humans. So far, scientists have found no evidence that bedbugs are capable of transmitting diseases to human hosts. For this reason, theyre considered a nuisance pest rather than a health threat. But even though they dont transmit diseases, bedbugs arent harmless. Some people experience severe allergic reactions to bedbug bites, and people who are bitten sometimes suffer from secondary infections. The emotional stress of dealing with a persistent bedbug infestation can also have a negative impact on your health. Bedbugs Can Survive a Year Without a Meal Technically, this is true. Under the right conditions, bedbugs have been known to survive as long as a year without a meal. Bedbugs, like all insects, are cold-blooded, so when temperatures drop, their body temperatures decrease. If it gets cold enough, bedbug metabolism will slow down, and theyll stop eating temporarily. However, it is highly unlikely that it would ever get cold enough in your home to trigger such a long period of inactivity. For practical purposes, then, this statement is false. At normal room temperature, a bedbug might go as long as two to three months without a meal, but thats about it.

Super Size Me Essay Example Super Size Me Essay Super Size Me Essay Morgan Spurlock, was the age of 33 when he ventured on his quest to answer the question?   â€Å"What would happen to my body, if I ate exclusively at McDonald’s fast food restaurant, eating 3 full meals a day for 30 days?†Ã‚   Not only did he have to take in tremendous calories, but he also had to Super Size his portions, when ever asked if he would like to do so. The health conditions that Morgan Spurlock developed were a direct result from eating the high fat and calorie and foods that he ingested during that 30 day period. The fact that Morgan Spurlock was a of a young age, healthy and of average weight for his height, 185 1/2 pounds and 1.88 millimeters tall, before the experiment ever took place, gives us a place to start from.   From that point of his weigh in until the thirty day period ended, Morgan Spurlock had gained a whopping 24.5 pounds and his overall body mass index grew from 23.2 to 27 which made him overweight for his body structure. When Morgan Spurlock learned of the great number of people in America who suffered from being overweight, he launched a plan to investigate how America’s love for fast food affected their weight and health.   By starting at an average size, he very clearly confirmed that his belief that the fatty food, directly affected the diets of individuals who ate at McDonalds, repeatedly. McDonald’s breakfast launched Spurlock’s study, and by the second day he ate ingested his first meal that was Super Sized!   He ate a Double Quarter Pounder with cheese, with the Super Sized fries and drink.   He reported that he was feeling uncomfortable while he was eating the meal and eventually vomited in the parking lot of McDonald’s.   He steadily ate the food and gained nearly ten pounds. Feelings of depression, which his girl friend, Alexandra Jamieson confirmed, participated in Spurlock’s experiment, said that Spurlock lethargy, and several headaches, learns that are lifted when he eats more of McDonald’s fast food.   One of his doctors said he was addicted to the unhealthy food.   Soon after, while continuing to eat the same food, he gained another ten pounds.   He now weighed in at 203 pounds and at the end of the month he weighed in at 210 pounds. When Morgan Spurlock begins to have palpitations in his heart, near the twentieth day of the experiment,   he went to see on of his physicians who was involved in his experiment.   He didn’t take any medications because he felt it would interfere with his experiment. One of the health problems that Morgan Spurlock was diagnosed with on completion of his experiment was liver problems.   Dr. Daryl Isaacs confirmed that Morgan Spurlock’s liver was pate and immediately advised him that he should stop the experiment or else he could suffer with a serious heart problem.   Dr. Isaacs told him that he would be like the character in a movie, where the person intentionally drank excessively, trying to kill himself.   Spurlock was very concerned about what the Pysician reported to him, but continued on with his mission of proving that fastfood is bad for your health. I’ll begin with the liver problem that Spurlock developed during his fast food eating frenzy.   When Dr. Daryl Isaacs examined Spurlock, he concluded that he had developed the pate liver.   Non alcoholic fatty liver disease is an accumulated deposit of fat into the liver without the use of alcohol as a contributor.   This fat causes the liver to swell.   Insulin resistance is believed to be a factor in this liver inflamation. The heart palpitations in which Spurlock experienced was due to the fact that he incurred high blood pressure from the high calorie, high fate, and no exercise routine that contributed to his heart palpitations.   (Merck Manual of Medical Information,1997) â€Å"Whether the heart palpitations are normal depends on answers to a number of questions, such as whether anything seems to bring them on, whether they started suddenly or gradually.†Ã‚   It was quite obvious when a person goes from a healthy life style and nutritional diet to a diet consisting only of McDonald’s fast food, where he is to only eat a salad, every tenth day, that he is going to incur health problems, as Spurlock most certainly did. (The Journal of the American Medical Association, 2007) states that there is a need for an efficient daily diet to sustain a healthy heart.   High cholesterol, high fat, low nutritional value foods contribute to an unhealthy heart and body. (Roberta Larson Duyff, 2006) What we eat determines how healthy we are.  Ã‚   Spurlock’s study did prove beneficial and he was able to shed light on the importance of a healthy diet and the need for a healthy daily exercise routine.

Project - Research Paper Example 2006). Furthermore, the project will utilize locally available materials and hence individuals will earn a living as a result. Of important to note it that the new road design require little maintenance and hence a lot of saving will be made. The road design creates emergency section for ambulances and breakdowns. This makes it easier to respond to various crises along the three-lane road, (Dibb, S. 2009.) Since many pedestrians and drivers have no prior experience in using such roads, a lot of training and workshops require to be initiated so as to equip them with the relevant information. When drivers use the frontier lane without controlling the access to the main lane, this increases the number of intersections and hence conflicting points (Frank, R. et al 1972). A large number of conflicting points usually lead to congestions and accidents. Though materials for building the road will be purchased from the locals, it is important to note that most of the materials are not available locally. In addition, locals will only be employed for manual jobs only. Senior positions will filled by the contractors. Lastly, the project has no plans on how vandalism of lighting and metal barricades will be reduced, (McDonald, M.
