Also in Korea! Super Whitefly” increases its damage by “re-entering” Japan…sucking human blood and “reproducing eternally”.
The infestation is “super bed bugs,” which insecticides do not work on.
Most bed bug bites are on exposed hands and feet while sleeping. Some people suffer insomnia due to the intense itching.
The itching from insect bites is caused by the salivary gland component of the injected insect. The itching occurs as an allergic reaction; the first time you are bitten you have no symptoms, but if you are bitten several times, itching and redness occur the next day or two.
After several more stings, itching appears soon after the sting. Occasionally, large redness and swelling with lumps may appear.
Topical application of medication can improve symptoms within a week to 10 days, but “the difficult part is the diagnosis leading up to treatment,” says Dr. Natsuaki.
In many cases, subjective symptoms appear one or two days after being bitten, so it is difficult to know when and where the bite occurred. In addition, since the symptoms are not so different from other insect bites, there are cases in which bed bugs are diagnosed as simple insect bites and treated without being aware of the bed bugs, and then the symptoms worsen.
To confirm the diagnosis, it is necessary to find bed bugs that must be somewhere. Dr. Natsuaki recommends the “lie-down strategy” as a method of almost certain capture.
By using their nocturnal nature, bed bugs can be captured with a high probability by pretending to sleep for 20 to 30 minutes and then quickly turning on the lights to see bed bugs gathering on bedding and limbs.
The “lie-down strategy” uses you as a “decoy” to lure the bed bugs to you. The bed bugs captured by this method are brought to the doctor’s office to confirm the diagnosis. Another thing that Dr. Natsuaki finds troublesome is the difficulty of extermination.
Most of the bed bugs that are spreading around the world are insecticide-resistant bed bugs, a type of bed bug that does not respond to common insecticides,” says Dr. Natsuaki. They are also called “super bed bugs.
There are some insecticides that are effective against bed bugs, but they are often not available in drugstores. If you do use them, you must anticipate the routes and areas bed bugs will take and spray them, which can make it difficult to get rid of them yourself unless you know their biology.
If there is one bed bug, the possibility of it breeding in all rooms is great, so it is best to use a reliable pest control service.
