For decades, Kenya has established itself as a key player in the fight against the trafficking of elephants, rhinos, pangolins, and exotic birds.

A Chinese national was stopped at Jomo Kenyatta International Airport (JKIA) back in March 2026. He was carrying around 2,000 live giant African harvester ants in special test tubes and syringes. This incident made big news, not just in conservation groups, but everywhere.

This isn’t the first time something like this has happened; it’s actually part of a bigger trend that’s been going on since 2023. Because of this, the people in charge in Kenya, the courts, and those who care about animals are having to rethink what they consider a crime against wildlife.

A Worrying Pattern

The March 2026 arrest of Zhang Kequn at JKIA closely resembles a case that captured the nation’s attention less than a year earlier. In April 2025, two Belgian teenagers, a Vietnamese national, and a Kenyan broker were caught with over 5,000 live queen ants packed into 2,244 cotton-wool-lined test tubes at a guest house near a national park.

A Nairobi court convicted all four, imposing a KSh1 million (around $7,700) fine on each or a year in prison, marking the country’s first prosecution of its kind for biopiracy on this scale.

Zhang’s case followed the same pattern nearly a year later. He pleaded guilty to wildlife trafficking without a permit at the JKIA Law Courts, and Principal Magistrate Irene Gichobi imposed a similar penalty: a KSh1 million fine or 12 months in jail. Approximately half of the insects he possessed were Messor cephalotes, the giant African harvester ant, kept alive in small test tubes designed to preserve them for weeks during transit.

These are not the first such cases. As early as 2023, three Kenyans attempted to export harvester ants, valued at approximately KSh300,000, to France. Investigators say the trend has only grown since then, with Nairobi, Gilgil, and Naivasha emerging as hotspots for collectors seeking out the red mounds that mark a colony’s location.

Why the Ants are Smuggled

To understand why someone would risk jail for an insect, it helps to look at the market that has formed around them.

Ant-keeping has become a popular hobby across Europe, China, and Vietnam over the past decade. Enthusiasts keep their colonies in clear containers called formicariums, watch the insects build tunnels and forage; they gather at shows to admire different species. Many find the hobby calming, even meditative.

Messor cephalotesis high on collectors’ lists because of their size, complex colony behaviour, and the unusual social dynamics within their colonies. Queens grow between 20mm and 24mm long, can live for decades, and can start new colonies on their own, making a single smuggled queen more valuable.

Dino Martins, an entomologist in Kenya, quoted by The Guardian, said, “They’re like the tigers of the ant world, just rare and beautiful and interesting.”

UK sellers have advertised individual ants of various African species, priced at £17 to £129, and dealers say a single giant African harvester ant queen can fetch up to £170, or roughly $220, once it reaches buyers in Europe or Asia.

A shipment of a few thousand ants isn’t just a curiosity; it’s a parcel worth tens of thousands of dollars upon arrival, even though the ants are collected cheaply in the Kenyan bush. Online marketplaces have driven this demand even higher. A 2023 study in the journal Biological Conservation tracked nearly 59,000 ant colony sales advertised online in China over six months, covering more than 200 species.

Researchers found that over a quarter of those colonies were occupied by invasive species outside their native range. Retailers and forums, some based in the UK and Europe, openly list African species for sale. Facebook groups dedicated to ant-keeping connect buyers with sellers and sometimes with smugglers. In one 2025 case, a Belgian suspect was part of a Facebook group where members swap tips on housing and feeding colonies sourced from around the world.

On at least one European retail site, a single queen of the Kenyan garden ant species has been listed at around 180 euros, about KSh26,500, showing how a few thousand insects collected cheaply in the wild can turn into a lucrative deal once they clear customs abroad. Social media rarely hosts illegal transactions directly, but it serves as a recruitment and advertising platform that normalises the hobby and quietly expands the pool of buyers willing to pay top dollar for rare African species.

Evading Detection at Airports

What makes ant trafficking especially difficult to combat is precisely what sets it apart from poaching elephants or rhinos: there are no carcasses, no tusks, and no obvious contraband.

In both the 2025 and 2026 cases, smugglers used nearly identical methods, storing live queens in small plastic test tubes capped with cotton wool, sometimes alongside syringes, to keep the insects alive and hydrated for up to two months. These containers are small enough to bypass casual searches and were reportedly designed specifically to evade X-ray scanners at airport security.

Within these trafficking networks, the division of labour closely mirrors that of larger wildlife crime operations. In the 2025 case, the two Belgian nationals collected the ants from their distinctive mounds in the Kenyan countryside; a Vietnamese national acted as a courier or “mule”; and a Kenyan served as the broker, connecting the foreign buyers to local networks.

Wildlife crime analysts say this structure shifts the legal risk onto low-level collectors and couriers. At the same time, financiers and buyers further up the chain remain protected, a common trait in organised wildlife crime, whether involving ivory or insects.

Detecting this type of trafficking presents specific technical challenges. Conventional X-ray scans and sniffer dog training are typically focused on drugs, explosives, and larger wildlife products like ivory or pangolin scales, not small, ventilated containers designed to keep insects alive.

According to wildlife crime expert Charles Ochieng, detecting ants and other insect smuggling through airports requires improved detection equipment that should be capable of identifying small, ventilated containers designed to sustain live insects such as ants during air transportation.

Ochieng says this should be implemented in major transport hubs.

A customs official at JKIA has reported finding termites, frogs, and even snake eggs in travellers’ luggage, indicating that techniques developed for smuggling ants are already being adapted for other small, overlooked species.

Troubling Shift and Diversification of Trafficking

Ants have become a new front in the illegal wildlife trade, but they are part of a much larger, longstanding problem. Kenya remains a key transit and source country in Africa’s illicit wildlife industry, which the US State Department and others rank among the largest global illegal trades, generating an estimated $7 billion to $20 billion annually.

Elephant ivory and rhino horn remain the most lucrative and visible commodities in this trade. In late January 2026, the Kenya Wildlife Service (KWS) arrested three suspects in the Lokichar area. Authorities recovered 42 kilograms of elephant ivory, along with leopard and python skins, which were being transported by motorcycle to buyers elsewhere in the country.

Pangolin scales, mainly destined for East and Southeast Asian markets, and snake products for exotic leather and pet trades, illustrate a trafficking economy that involves nearly every branch of the animal kingdom. Officials at the Kenya-Tanzania border have intercepted raw and processed rhino horn and ivory, live pangolins, sandalwood, and venomous and non-venomous reptiles, all targeted for Europe’s illegal pet trade at crossings like Lunga Lunga, Tarakea, Loitoktok, and Isebania.

Conservationists argue that the range of species now considered worth risking arrest for has widened. The KWS describes recent ant cases as evidence of a troubling shift and diversification in trafficking patterns, moving away from large, charismatic mammals to lesser-known species that still play vital ecological roles.

Historically, insects, amphibians, and small reptiles received less enforcement attention than elephants or rhinos because the public and the law often failed to recognise their value or vulnerability.

Kenyan Law on Wildlife Trafficking

Kenya’s 2013 Wildlife Conservation and Management Act provides prosecutors with a clear legal foundation to pursue ant traffickers: Section 99 specifically criminalises the unlicensed collection and export of wildlife, including ants.

Additionally, the KWShas invoked the Nagoya Protocol, an international treaty Kenya joined in 2014, which regulates access to genetic resources and mandates that any benefits derived from their use be shared fairly with the country of origin. Officials and lawyers involved in recent cases have described the illegal export of ants not just as smuggling but as biopiracy, exploiting a country’s biological resources without permission or compensation.

Despite these legal tools, gaps remain. Messor cephalotes is not listed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), nor has the International Union for Conservation of Nature (IUCN) formally classified it as threatened.

This means governments are not required to track their population or monitor cross-border trade in the species, leaving enforcement agencies without the baseline data needed to assess how serious a seizure truly is.

A recent legal commentary on the Zhang case pointed out that Kenyan courts have, in effect, had to interpret the Wildlife Conservation and Management Act as applying to all biological species, rejecting the idea that invertebrates are somehow lesser wildlife that deserve lighter penalties.

Kenya has taken steps to tighten penalties across the board. President William Ruto signed legislation in 2025 that increased maximum fines for wildlife trafficking to as much as KSh100 million, along with prison sentences of up to twenty years for the most serious offences involving protected species.

Whether such penalties will significantly impact insect trafficking, where individual fines have so far hovered around KSh1 million, remains an open question.

The Ecological Stakes

Taking ant smuggling seriously isn’t just about legal issues. Giant African harvester ants play a key role in spreading grass seeds across East Africa’s savannahs. As they forage, they carry seeds back to their nests and drop others along the way, helping grasslands grow over extensive areas.

“Harvester ants are seed collectors, and they gather seeds as food for themselves, storing these in their nests. A single large harvester ant colony can collect several kilos of seeds of various grasses a year. In the process of collecting grass seeds, the ants drop a number, dispersing them through the grasslands,” Dino Martins told The Guardian.

Queens are the heart of their colonies, producing workers, soldiers, and future queens that keep the colony going for years or even decades. Removing thousands of queens at once, as seen in large seizures, risks upsetting the balance of the colonies and the ecological processes they support.

The danger works both ways. Scientists studying global ants warn that species moved outside their native ranges can become invasive, harming agriculture and ecosystems in the new areas.

A 2023 Biological Conservation study raised concerns about Messor cephalotes, which was introduced into southeastern China. Its diet and foraging habits overlap with local crops, risking disruption to grain production, which is crucial for the region’s food supply.

What doesn’t cause much harm in its native savannahs could, thousands of kilometres away, turn into a serious agricultural pest.

Tightening Enforcement

Researchers at the Institute for Security Studies and other organisations tracking the trend say that closing the enforcement gap requires action on multiple fronts. Better-trained customs officers and equipment capable of detecting small, ventilated containers would help address the immediate enforcement issues at airports like JKIA.

Raising awareness within communities in known harvesting areas is just as important because ants are often seen as a nuisance rather than a resource worth protecting. The mindset makes early detection and reporting less likely than it is for, say, elephant carcasses.

Globally, conservationists are pushing to include smaller species in the same international conventions that regulate ivory and rhino horn, especially since ant-keeping has gained popularity in many European and Asian countries,driving demand.

Without a coordinated framework, Kenya’s courts will continue convicting individual smugglers one test tube at a time while online marketplaces and collector networks, which fuel demand, keep operating largely without restrictions. For now, the giant African harvester ant has become an unexpected test case for how seriously a country’s wildlife laws treat the small, overlooked, and unfancied species.

Kenya’s courts have responded by treating an ant smugglers the same as any other wildlife trafficker. Whether this approach applies to the dozens of other lesser-known species passing through the same airports in similar containers will determine how much protection Kenya truly offers its smallest wildlife.
