On March 10, 2026, 27-year-old Zhang Kequn was stopped by airport officials at Nairobi’s Jomo Kenyatta International Airport as he prepared to board a flight to China. His luggage contained 1,948 live queen garden ants of the species Messor cephalotes packed in specialized test tubes, with an additional 300 ants hidden inside three rolls of soft tissue paper. The ants were highly prized queen ants, the reproductive heart of any ant colony, and a hot commodity among collectors and exotic pet enthusiasts in Europe and Asia. This seizure alone could be valued at over $500,000 on the open market, highlighting the lucrative nature of the trade.
Investigators say Zhang was the mastermind behind the trafficking ring and escaped Kenya last year using a different passport. Kenyan authorities had previously placed a stop order on Zhang Kequn's passport after he allegedly evaded arrest in connection with a similar smuggling network last year. A tip-off and careful monitoring led to Zhang Kequn's interception, and investigators say Zhang had been in Kenya for two weeks and was supplied with the ants by three local accomplices. Investigators believe Zhang Kequn may be the mastermind of a wider trafficking ring that first came to light in 2025, underscoring his alleged central role.
This recent arrest echoes a previous major case from last year, where 5,000 giant harvester ant queens were found alive at a guest house in Naivasha. The suspects in the Naivasha case were from Belgium, Vietnam, and Kenya, and the ants were packed in test tubes and syringes with moist cotton wool to survive for two months. The plan was to take the ants to Europe and Asia for sale, and last year, two Belgian teenagers were charged with wildlife piracy for possession of 5,000 ants valued at 1 million shillings ($7,700). In 2025, four men—two Belgians, a Vietnamese national, and a Kenyan—were caught attempting to smuggle thousands of live queen ants out of the country, and the four men from the 2025 case pleaded guilty and were sentenced to a year in prison or a hefty fine of about $7,700 each. The KWS described last year's ruling as a 'landmark case', and the 2025 case was described by authorities as a 'coordinated, intelligence-led operation'.
In the current case, a Chinese national and a Kenyan man were charged with unlawfully dealing in wildlife species for possession of hundreds of live ants. The suspects were identified as Zhang Kequn and Charles Mwangi, and prosecutors say Kequn paid 60,000 Kenyan shillings ($463) for 600 ants and 70,000 shillings ($540) for 700 ants from Mwangi. The suspects did not have required permits under Kenya’s wildlife conservation laws, and prosecutor Allen Mulama said 1,948 garden ants were packed in specialized test tubes and 300 were concealed in tissue paper rolls. The court allowed prosecutors to detain Zhang for five days for further investigations, and the court ordered the men to remain in custody, though the men deny committing crimes.
The market demand driving this illegal trade is significant, with giant African harvester ant queens able to fetch up to £170 ($220) on the black market. The Kenya Wildlife Service warned of growing demand for garden ants in Europe and Asia as pets, and ant enthusiasts in Europe and Asia keep them as pets and pay large sums for them. The black market for ants is driven by the growing popularity of formicariums—specialized transparent enclosures where hobbyists can observe ant colonies up close, and in Europe and Asia, collectors are willing to pay a premium for rare species like Messor cephalotes. A single smuggling attempt can be potentially worth tens of thousands of dollars, fueling the illicit activity.
The ants involved, Messor cephalotes, are native to East Africa and known for their seed-gathering behavior. Messor cephalotes ants are protected, and their trade is strictly regulated, emphasizing their legal status and ecological importance.
The Kenya Wildlife Service said illegal export of ants undermines Kenya’s sovereign rights and deprives local communities of benefits. The Kenya Wildlife Service has warned that the removal of large numbers of queen ants from the wild poses a significant threat to local ecosystems, highlighting conservation concerns.
International connections are suspected, as the Kenyan man is suspected of being linked to another ant shipment seized in Bangkok in March. This suggests a broader network beyond Kenya's borders, though the full scope remains unclear.
The exact scale of the trafficking network is not fully known, including how many local accomplices are involved in supplying ants to Zhang Kequn and whether they have been identified or arrested. Additionally, the specific evidence linking Charles Mwangi to the ant shipment seized in Bangkok in March has not been disclosed, and the exact timeline and method Zhang Kequn used to escape Kenya last year with a different passport remain uncertain.
Further unknowns include what specific ecological impacts have been documented from the removal of queen ants from Kenyan ecosystems, as well as how widespread the ant-trafficking network is and whether there are other key figures beyond those already arrested.
Data contradictions exist in the cases: the total number of ants seized in Zhang Kequn's arrest is reported as 2,238 ants by some sources, while authorities found 1,948 garden ants in specialized tubes and 300 ants in tissue rolls, totaling 2,248 ants, a discrepancy of 10 ants that affects the reported scale and potential market value. Additionally, payment details for ants in the recent case show a disagreement, with some reports stating the Chinese man allegedly bought the ants from the Kenyan man and paid about 10,000 Kenyan shillings (about 67 euros) per 100 ants, while prosecutors say Kequn paid 60,000 Kenyan shillings ($463) for 600 ants and 70,000 shillings ($540) for 700 ants from Mwangi, indicating different transactions, pricing structures, or inaccuracies in reporting.
