The "Bed Bug Map" has been online for more than a month, attracting more than 300,000 users across the country and marking a total of 691 hotels. The popularity and controversy of this mini program exceeded the expectations of the developer Wang Chuang.
In his mind, the first wave of popularity occurred shortly after the mini program was launched in mid-September. Users search or mark records of suspected bed bugs according to cities and hotels, exchange experiences after being bitten in the comment area, leave messages like "the developers are doing good things," and call the mini program a "folk lightning protection tool."
It has been hotly debated by the public again and has continued since the end of October. The mini program was suspended twice and re-launched after rectifications. Images uploaded by users are no longer made public. The professionalism, security and compliance issues of a personal mini program have been put on the table, with users supporting it and hotels complaining. "This is just a convenient query tool." Wang Chuang told China News Weekly. Already, hotels have submitted third-party inspection reports and had their marks revoked after appeals. As for whether the disinfection is in place, he has not seen it in person and will not comment. However, the hotel is willing to do disinfection and show this work. He feels that "it is getting better."
Has a hotel been accidentally damaged?
Zhou Jun runs a 30-room budget hotel in the old town of Zhengzhou. One day in early October, he suddenly received a call from a disinfection company claiming that his hotel had bed bugs (i.e. bed bugs) and asked if it needed to be disinfected. This was the first time Zhou Jun heard about the "Bed Bug Map" applet from the other party's mouth.
He went in dubiously and searched for the name of his store. A dark red circular logo popped up on the map, with a simple image of "Bedbug" in the middle. When I clicked on the hotel details page, 5 users had already reported it, and the supporting information was "infested with insects". Zhou Jun could not see the pictures, could not find the room where the incident occurred, or the guest's check-in time, and could not carry out targeted disinfection. He immediately contacted the disinfection company he had cooperated with for a long time to come to the door and conduct an inspection of the entire store.
"Neither the store nor the online booking platform has received any complaints related to bed bugs." Zhou Jun told China News Weekly that the hotel signed an annual disinfecting contract with a third party and carried out regular operations every month. He was worried that it might have been "misjudged". Referring to the appeal guidelines given by the AI tool, Zhou Jun uploaded the third-party disinfection report and found the "audit passed" message the next day, but the hotel is still marked on the map.
Also stuck at the "approved and marked still" step is Chengdu Yongsheng Hotel. The owner, Tao Bo, remembers clearly that at about 7pm on November 2, he received a WeChat notification from the community street office, saying that the hotel had been marked as a health problem on the "Bed Bug Map". Along with the message, there was also a news article about this mini program. He hurried back to the store and was told to cooperate with various departments in the district to investigate the next day.
Tao Bo told China News Weekly that the hotel is disinfected once a week in summer and once a month in winter. It pays a third-party disinfection agency nearly 10,000 yuan every year. Every inspection and disinfection is recorded. The report generated based on this was later uploaded to the "Bed Bug Map". The hotel's complaint has been approved.
On the homepage of the "Bed Bug Map" applet, the icon of Yongsheng Hotel has changed to half red and half blue. However, according to community rules, the "Report with Pictures" mark will be retained for 90 days. After expiration, it will be converted to a normal green mark. The hotel will no longer be displayed on the homepage map and the "Problem" business list, but the record will not be deleted and will continue to be retained in the "Invalidation Report Storage".
What troubles Tao Bo is that the hotel he runs has been reported by nine users on the mini program. According to the "Picture Evidence Review Record from September to October 2026 - Final Version" compiled by developer Wang Chuang, this hotel was reported to have bed bugs at 5 a.m. on September 26, and the pictures were reviewed and approved by the administrator. Tao Bo suspected that he had been maliciously smeared, and what he wanted to solve most now was how to remove the mark as soon as possible. Chengdu is a tourist city, and foreign tourists are accustomed to reading online guides before traveling. The impact on off-season orders is not obvious yet. He is worried about the next peak season.
“The function lies in being seen.”
As of November 8, the complaint list of "Bed Bug Map" shows that 100 hotels have passed the review. The uploaded complaint materials include third-party disinfecting reports, disinfecting photos, official participation in supervision and other records.
"The hotel complaint function was added at the end of September." Wang Chuang recalled that this function was added to provide updated channels for hotels after rectification, as well as to provide appeal channels for hotels that may have been misjudged or maliciously complained. He emphasized that he is only the initiator and does not provide opinions. The final judgment is made by consumers.
On social platforms, some netizens living in Europe reminded that overseas statistics show that because bed bugs are not common, the public has a high rate of misjudgment and false alarms. It is recommended that individuals reporting mini programs "be sure to bring pictures" to avoid "accidental damage" to hotels due to panic.
Regarding the authenticity of personal reports, Wang Chuang responded that after the mini program was updated, all reports without evidence have been blocked. Reports with incomplete information will be rejected. Users cannot prove encountering bed bugs based on bite marks alone. It is recommended to provide accommodation orders, photos or traces of bugs, medical records and other information, along with detailed descriptions. From September to October, he rejected 284 reported records and retained 461.
Wang Chuang said that in order to improve the accuracy of user reporting, the current version not only raises the reporting threshold, but also adds common insect identification diagrams, corresponding wound diagrams and other prompts under the user review page.
"Many functions are updated after reminders from users in the comment area." Wang Chuang said frankly that the role of the map is to "be seen." As for whether there is a spread, official departments need to investigate. Currently, the tagged hotels are concentrated in the developed areas along the eastern coast, followed by the central part, and the western part has not yet been covered. There is currently no statistics on which types of hotels have more concentrated problems.
Wang Chuang is 26 years old. He has a master's degree and works in the manufacturing industry. He has nothing to do with programming. In May and June of this year, he opened an "AI Maker" account, tried to write code with AI, told the AI the desired functions in vernacular, and then made adjustments little by little. The first small program "Time Note" received a mediocre response after it was launched, but this helped him build his own workbench step by step, constantly optimizing the user interface, functional logic, front and back integrity and other "detailed work". These experiences were later used in the "Bed Bug Map".
In June this year, Wang Chuang was bitten by a bug after moving. He searched for keywords such as "little black bugs on the bed", and the social platform pushed a batch of serious bite cases in hotels and posts about densely crawling bug swarms on individual beds. He started building the framework in July and spent a lot of time waiting for the mini program to be filed. At 8 p.m. on September 16, the mini program was launched. He thought “there will still be no splash.” However, at noon the next day, it received more than 200 likes, and the number of views exceeded 100,000 by the evening.
Wang Chuang recalled that the "Bed Bug Map" has undergone at least four important updates since its launch. These operation and maintenance tasks are all completed during his rest time after get off work. There are dozens of pieces of information reported by users every day, and sometimes it takes three or four hours to process.
The most tiring job is "judging evidence". The situations reported are all kinds of strange. Many users feel that the hotel is not clean but they still want to mark it. These situations need to be screened and filtered. In order to comply with the regulations of the platform, the pictures uploaded by users will no longer be made public, and the judgment work will be borne by Wang Chuang alone from the original "netizen co-construction". So far, he has processed the information reported by 691 hotels, of which 421 were approved and 270 were rejected.
compliance boundaries
Before this mini program was launched, the issue of bed bugs had already sparked several rounds of heated discussions. Related terms have been on the hot search list, and the current topic page shows that the number of reads has reached 47.108 million.
However, Wang Desen, an associate professor at the Department of Entomology at South China Agricultural University, said that hotel hygiene is "not closely related" to the presence of bed bugs. Staff turnover is too fast and repeated introductions are unavoidable. Conventional disinfectants often cannot kill the bugs if they do not come into direct contact with them. What is even more difficult to prevent is that bed bugs will lay their eggs in the gaps. He also said that bed bugs have never really gone away, and have been getting worse across the country in recent years.
Zhou Jun admitted that to deal with the problem of bed bugs, the United States and Canada have long had private databases such as the Bed Bug Registry. The logic is similar to the "Bed Bug Map": guests submit their experiences anonymously, and the platform does not conduct professional verification, and the authenticity of the reports can only be judged by oneself. According to media reports, high-end hotels such as New York Waldorf Astoria and Marriott Marquis have been on the list. "The reported information can only be used as a reference and does not mean that there are pests confirmed by professional agencies."
China Central Broadcasting Network mentioned in its comments that relying on a netizen's "hand-rubbed" map to supplement health information itself shows that there is a lack of formal channels. The fundamental solution is not to get more people to draw maps, but to have records where records should be recorded.
Tao Bai hopes that the mini program will introduce official guidance. He claimed that he recently communicated with many hotels and found that "there are malicious complaints". He hopes that third-party supervision can be combined with the results of local health law enforcement to conduct cross-verification, multiple audits, and even introduce professionals to identify pests to reduce harm to regular businesses. Tao Bai learned that a hotel in Chengdu was already collecting evidence and preparing to prosecute.
Fu Jian, director lawyer of Henan Zejin Law Firm, told China News Weekly that the original intention of this small program to collect and display hotel bed bug-related information was to help the public avoid accommodation risks and has certain social value, but it still involves multiple legal risks. If users post false reviews at will and provide evidence maliciously, it may constitute reputation infringement, and in serious cases, it may also involve breaking the law. Platforms have the obligation to review information and should establish a verification mechanism to prevent the spread of false information. At the same time, platforms must also pay attention to the protection of personal information and the boundaries of professional evaluation, and cannot allow the spread of unverified information.
