Also in Korea! Super Whitefly” increases its damage by “re-entering” Japan…sucking human blood and “reproducing eternally”.
Experts say the pests are highly resistant and difficult to exterminate on their own.
In Japan, dermatitis caused by the pest bed bugs was confirmed around ’05, and from ’15 to ’19, the number of bed bugs increased rapidly, and I felt that this would be a serious problem.
At that time, it was a period when the number of foreigners visiting Japan increased rapidly due to inbound travel. After that, the epidemic temporarily stopped because the movement of people was restricted due to the new corona, but it has increased again since the corona was classified as class 5.
Since May of this year, the number of patients has increased dramatically, and most of them seem to have brought it back from their travel destinations.
Most of the patients seem to have brought it back from their travel destinations,” said Dr. Masaru Xiaju, a professor at Hyogo Medical University and an expert on skin diseases caused by insects.
In France, where the Olympics will be held in Paris next summer, bed bugs have become a social problem due to the large number of bed bug infestations. Sightings of bed bugs have been reported at residences, hotels, movie theaters, and other locations throughout the city, and the situation seems to have become so serious that the National Assembly is considering countermeasures.

Bed bugs are pests that repeatedly reproduce by sucking human blood, and although they were once thought to have been drastically reduced, they have been confirmed again since 2005, and their damage has been increasing in Japan over the past few years. The reason for this is related to human traffic.
In Japan, the number of bed bugs increased around World War II, then declined sharply around 1970 due to the spread of insecticides and changes in living conditions. From then until around 2005, bed bugs were so rare in Japan that they could be called an endangered species,” says Dr. Masaru Natsuaki of Hyogo Medical University’s Department of Dermatology.

Bed bugs travel by burrowing into clothing, documents, and other luggage carried by people. They are spread by visitors to Japan who bring them with them to their accommodations, or by Japanese travelers who bring them back from their travels and then “re-enter” the country.
They live in houses and inhabit the crevices of the house. During the day, they hide in cracks in pillars, in furniture and furnishings, in beds, behind pictures on the wall, and in electrical appliances and books.
At night, they emerge from the crevices to feed on human blood and return to the crevices when their stomachs are full. In many cases, they are hard to find when you look for them, and by the time you find them, they have infested the entire house in large numbers.
Once even a single animal is brought into the house, they steadily increase their offspring in a comfortable, air-conditioned environment. The abundance of human blood as food and the lack of other natural enemies make it difficult to stop them from reproducing.
Many insect females can store enough sperm to lay eggs for the rest of their lives once they have mated with a male.
In other words, if even one adult female that has mated invades and lives there, she will survive by sucking blood at night and lay more than 200 eggs during her lifetime. Once the larvae grow up to one or two months and a female-male pair is formed, they will reproduce forever.”
