Original title: AI-Programmed "Bed Bug Map" Mini-Program Goes Viral, Over 600 Hotels Flagged, Some Consumers Applaud, Some Hotels Cry Foul; Developer Responds: Users Must First Submit Evidence and Pass Manual Review Before Flagging

Recently, a mini-program called "Bed Bug Map" has rapidly gone viral on social platforms. Users can "one-click flag" the location of hotels where bed bugs have appeared, and all netizens who use the mini-program can see it when they open it.

On November 1, due to platform regulatory requirements, the new version of the mini-program "Bed Bug Map," which had been suspended twice, was restored online. It is understood that the mini-program was developed by individual developer Wang Chuang using AI programming. Since its launch on September 21, it has rapidly attracted over 200,000 people, and the scope of flags has expanded from coastal major cities to the whole country, covering more than 600 hotels.

It is understood that the homepage map of "Bed Bug Map" can locate different cities on its own. Oval symbols of different colors represent different meanings such as bed bugs, cockroaches, other pests, and no evidence yet. The usage instructions clearly state that "the information is for reference only, and absolute authenticity cannot be guaranteed." Some users upload photos of skin covered in red spots, while others attach no images at all and merely leave a single sentence: "There are bed bugs."

Behind the mini-program's viral popularity is the "bed bug anxiety" that has continued to ferment since the beginning of this year. Searching "hotel bed bugs" on major social platforms brings up a large number of "avoidance posts," and related news has repeatedly trended.

Bed bugs are what people commonly call bedbugs. According to the Chinese Center for Disease Control and Prevention, "bed bug" is a direct Chinese translation of the English term "bed bug," and the formal Chinese name is bedbug. They hide during the day in gaps such as mattress edging and bed frame seams, and come out at night.

Many netizens, when sharing their experiences on social platforms, said that in the past, when they or people around them encountered bed bugs in hotels, they could only post avoidance posts sporadically on social platforms. Such content was easily buried by new information feeds, making it difficult for other consumers to find later. This mini-program is equivalent to centralizing scattered accommodation hygiene-related information, providing everyone with a unified query channel and genuinely reducing the probability of falling into pitfalls. Many netizens expressed support, believing it can force hotels to improve hygiene management.

As the mini-program's reach grows wider, controversy has followed. Some hotel operators have publicly cried foul, saying that some flagged content on the platform lacks objective basis, that there are cases of users casually marking based on subjective feelings alone, and even malicious flagging.

After being suspended twice, the team adjusted the mini-program's mechanism: "Hotels with bed bugs can still be flagged now, but users need to submit evidence first, and only after I manually review and confirm it can the flag be made."

Some netizens also questioned whether there is a possibility of "maliciously" smearing hotels. On the evening of November 1, the appeal list of "Bed Bug Map" showed that four hotels had uploaded detailed appeal materials, including business licenses, disinfection photos, and third-party disinfection records.

A staff member of Beijing Guangzhou Building Hotel introduced that a guest, two days after checking out, demanded a refund of nearly 3,000 yuan for four nights on the grounds of being bitten by insects, and posted about it on social platforms. Subsequently, hotel staff saw in the comments below the post that netizens suggested the guest mark the hotel on the "Bed Bug Map," and that was how they learned of its existence.

The staff member said that the hotel not only has complete monthly disinfection records, but after the incident, a third-party professional institution conducted a thorough inspection of the room involved and 24 randomly selected guest rooms, and no insect eggs or insects were found.

The staff member said that relevant departments conducted inspections and confirmed that the hotel's hygiene was compliant. "We uploaded these reports and records to the mini-program's appeal channel, and after approval, our flag information was removed."

The AI maker introduced that the mini-program's functions are constantly being patched. During operation, a mechanism for user participation in review was added, and a new feature is currently being updated—mandatory user upload of (bed bug) photos. He also added a voice channel for hotels: hotels can provide business licenses, disinfection photos, and third-party pest control institution reports and display them. By clicking on a hotel, users can see the user's pictures and the hotel's response, allowing both sides to speak.

Regarding the report determination mechanism, the mini-program adopts the principle of majority determination. The determination of a piece of evidence requires more than three people to choose that it is a bed bug. Below the user review page, a common insect identification chart and corresponding wound diagrams have also been added. "I am just an initiator. All the data and review of the mini-program are intended to mobilize everyone to participate together," said the AI maker.

"We cannot condemn all hotels with one stick. After hotels conscientiously disinfect and rectify, if there are no problems, they can actually still be stayed in. I believe hotels are willing to disinfect regularly," the AI maker emphasized, saying that he is only the initiator, does not provide opinions, and the final judgment is left to consumers.

"Bed Bug Map" mini-program developer @AI Maker Wang Chuang said in an interview that he made this mini-program using AI, "just specifically to give everyone a channel to exchange information." Facing huge traffic, he admitted: "Relying on me alone, there is certainly no way to make it perfect."

Wang Chuang's main business is manufacturing. He had not previously been exposed to programming and only began trying to write code with AI in July this year, developing in his spare time. What prompted him to develop this mini-program was his own painful experience of being bitten while moving. He noticed that channels for obtaining relevant information were scattered, consumers needed to spend a lot of time and energy searching, and some hotel "avoidance posts" were "deleted or blocked" after a few days, which he believed was detrimental to consumers' right to know.

On November 1, China National Radio commented that relying on a map "hand-made" by netizens to supplement hygiene information itself shows that there is a gap in official channels. The fundamental solution is not to have more people draw maps, but to ensure that places that should have records have records. At present, several mainstream domestic hotel booking platforms still do not have dedicated reporting and query entrances for issues such as bed bugs—this is exactly where action can be taken: platforms should build the channel, allowing guests to upload relevant photos and mark them by level, while also giving merchants room to appeal and have reviews reconsidered. Relevant regulatory authorities, in turn, can make disinfection records and regular spot-check results public, and truly incorporate hygiene conditions into merchants' credit evaluations to form long-term constraints.
