There are about 75 species of bedbugs, Insecta, Hemiptera and bedbugs in the world. In nature, bedbugs are usually parasitic on bats or birds. Bedbugs are actually one of many bedbugs. They also have smelly glands, which can secrete pungent odor. Bedbugs, also known as ticks and bedbugs, are gradually metamorphosed insects, and their development process mainly includes three stages: egg, nymph and adult.
The egg shell of bed lice is reticulate, with a cover at the front end, usually yellow and white, and rectangular. Nymphs are white and can suck blood like adults. The stink glands of nymphs grow on the back of abdomen, and those of adults grow on the chest and abdomen. Adults are generally reddish brown or black, and bed lice have smelly glands. Generally speaking, they will secrete smelly liquid in two situations:
1. Secreting smelly liquid plays a defensive role when encountering natural enemies.
2. Attract the opposite sex and promote mating.
Bedbugs are social animals, which usually move at night, but they will hide in gaps such as mattresses, springs, bedside drawers, skirting lines and ceilings during the day. They suck not only human blood, but also the blood of other animals. Bedbugs mainly find or locate food sources by detecting carbon dioxide exhaled by people. They have thermal sensors on their antennae, which can accurately locate people nearby.
The bug has a hard mouthpiece on its mouth, which can easily pierce human skin. In the process of puncture, people can hardly feel any pain, because they will immediately secrete saliva containing mild anesthetic, which also contains anticoagulant substances, so that blood can not be coagulated and the blood flow rate can be accelerated. It only takes five minutes for a bug to suck up. After being bitten by bedbugs, about 1/3 people will not respond. If they react, they usually have slight itching or redness, which makes people often mistake them for mosquito bites.
After being bitten by a bedbug, the wound will generally be red, swollen and itchy, but if scratched, it will often lead to bacterial infection, and if bitten for a long time, it may cause anemia. Bedbugs are very hungry insects. Their nymphs can go without food for 30 days, while their adults can go without food for 6 to 7 months. A scientist once kept a bug, which was only fed once every two years and eight months, but the bug was still there.
In the 1950s, Americans used DDT (bis-p-chlorophenyl trichloroethane) to eliminate bedbugs from the United States. However, many years later, the bug came back, and its reproductive ability was amazing. The bug of 1 can become 10000 in a month, and the returned bug becomes more resistant to drugs. Although bedbugs themselves do not carry diseases, they are very fragile once they are invaded. Americans were once shocked by the smell of bedbugs, and the news of bedbugs even surpassed the Gulf of Mexico and the rising unemployment rate. From September 20 10 to September 2065 438+22, Americans even held a global bug summit for it in Chicago.
The way to deal with bedbugs is usually to pour boiling water back and forth into the gap between the bed board and the furniture, or to expose bedding, straw mats and brown sheds to the sun, and at the same time pat, flip, shake them out to dry or kill them directly. Biologists have studied bedbugs and found that they usually prefer red or black to green or yellow, but their preference for color will change with age, hunger and gender. Hungry bugs have no interest in color.
In fact, bedbugs' preference for color has a lot to do with their intention to hide themselves. Bedbugs are red or black. They like to hide in dark places, so red and black can hide them better, while green and yellow look brighter. These two colors are not suitable for hiding. Therefore, changing the sheets and pillows into yellow or green can not only make it easier to find bedbugs, but also inhibit bedbugs. Of course, you'd better take the quilt out to dry, often.
