Super Ants from Uzbekistan cause power outages in the UK

Invasive species of super ants from Uzbekistan, known as "electro ants," have become a major threat to the UK's power infrastructure, leading to power outages and short circuits. The Daily Star reports on the growing concern surrounding these ants.

Origin and Impact of the "Electro Ants"

The ants, scientifically known as Lasius neglectus, first arrived in the UK in 2009, likely brought in through imported houseplants from Asia. These ants have shown a strong attraction to electrical wiring, causing disruptions in the power supply since their arrival. Experts warn that they have the potential to disable entire households due to their affinity for electrical infrastructure.

Characteristics and Spread of the Invasive Species

Lasius neglectus is native to Uzbekistan, where their nests form extensive interconnected tunnel networks covering large areas. Recent findings indicate that the queens of these ants are capable of flight, enabling them to establish new colonies and expand their territories at a faster pace than previously thought.

The Dangers Posed by "Electro Ants"

The presence of these ants poses significant dangers as they tend to build colonies around cables and electrical panels. Their activities can easily trigger short circuits, resulting in power outages and even potential fire hazards. Cleankill Pest Control Manager, Paul Bates, emphasized the risk associated with these ants.

The UK's Climate and the Rapid Expansion of "Electro Ants"

According to a study conducted by biologists at the University of York, the climate in the UK is favorable for the invasive species. The "electro ants" are capable of covering distances ranging from 20 to 50 kilometers annually from their nests, establishing new colonies within this radius. Multiple queens within a single Lasius neglectus anthill further contribute to their rapid proliferation.

Dr. Elva Robinson, a lecturer in ecology at the University of York, expressed concern about the impact of electric ants on the native ecosystem. She stated, "We think the invasive ants have the potential to have a big impact on the native ecosystem. In the sites we have studied, it is clear they are excluding the native ants. They are clearly dominating, and where they cluster, native species are being pushed out." Dr. Robinson's remarks highlight the aggressive nature of these ants and their ability to outcompete and displace the native ant species in the affected areas.

Spread of the Super Ants in the UK

The presence of Lasius neglectus was first identified in a garden owned by the National Trust Estate in Gloucestershire. Subsequently, these ants were found in several other locations across the UK, including Eastbourne, Hendon, and Cambridgeshire. Over time, colonies have been discovered in Yorkshire and along the south coast of England.

Environmental Impact and other invasive species

Scientists have expressed concerns about the environmental impact of these invasive ants. The rapid expansion of Lasius neglectus colonies is crowding out native ant species, leading to a decline in their populations.

This comes as the UK faces other environmental challenges, such as the impending arrival of hairy poisonous caterpillars in the summer of 2023. These caterpillars, known as the marching oak silkworm, pose a threat to both trees and humans, causing asthma and skin rashes upon contact with their larvae.

The authorities are closely monitoring the spread of "electro ants" and working on strategies to mitigate their impact on the power infrastructure and ecosystem.
