In Kenya, the rainy season has brought more than just fertile conditions for farming. It has also triggered a surge in the illegal trade of queen ants, particularly around the town of Gilgil.
During this period, swarms of winged ants emerge from anthills for mating. This natural event makes it easier for collectors to capture fertilised queens, which are highly valued on the global black market. These insects are sought after by hobbyists who keep them in transparent enclosures, known as formicariums, to observe colony life.
The most prized species is the giant African harvester ant, scientifically known as Messor cephalotes. Recognisable by its size and reddish colour, a single queen can sell for up to $220 (£170). With the ability to produce entire colonies and live for decades, these ants are particularly attractive to collectors.
According to testimonies, local intermediaries have been linking foreign buyers to collectors in rural areas. The ants are typically gathered early in the morning near open fields and transported in small tubes designed to keep them alive for weeks. Buyers often remain in nearby towns, avoiding direct involvement in the collection process.
Authorities began to grasp the scale of the trade after a major seizure last year in Naivasha, where around 5,000 queen ants were discovered in a guesthouse. The insects were carefully stored to survive long-distance transport to markets in Europe and Asia.
The illegal trade has surprised both scientists and conservation authorities, who are more accustomed to tackling wildlife crimes involving elephants and rhinos. Experts warn that removing large numbers of queen ants can have serious ecological consequences.
Entomologists describe these ants as essential to their ecosystems. They play a key role in seed dispersal and soil health, helping maintain balanced grassland environments. The loss of queen ants can lead to colony collapse, which disrupts biodiversity and local agriculture.
There are also international concerns. Researchers warn that exporting non-native species could harm ecosystems abroad if the ants escape captivity. Studies have shown that a significant proportion of ant species sold online are not native to the countries where they are kept, increasing the risk of invasive outbreaks.
Despite the risks, there is currently limited global regulation. No ant species is listed under international wildlife trade agreements, making enforcement difficult. In Kenya, legal collection is possible with permits, but officials say none have been requested so far.
The Kenya Wildlife Service has called for stronger monitoring at airports and border points to curb trafficking. Meanwhile, some experts argue that the trade could be formalised and regulated to create economic opportunities for local communities.
As debate continues, the situation highlights a growing tension between conservation concerns and the commercial potential of an unusual but increasingly lucrative wildlife market.
