Israeli Initiative Targets Invasive Fire Ant Spread with Precise Monitoring and Local Action
The invasive little fire ant (Wasmannia auropunctata), originating from the Amazon, has been spreading across Israel for over two decades and is now a permanent presence rather than a temporary guest. The challenge has shifted from eradication to containment, as effective pesticides also harm native species like local ants, crickets, butterflies, and bees, and large-scale annual treatments are costly. Asaf Miron, a high-tech designer and resident of Kfar Sirkin, developed a precise monitoring and targeted treatment initiative to combat the fire ant's spread. He explains that the ant displaces native ants and attacks various species, even climbing trees to prey on nestlings, and has no natural enemies in Israel.
Miron will present his project at the 54th Annual Science and Environment Conference on July 8-9 in Jerusalem. He conducts lectures in rural communities to raise awareness about the fire ant's destructive impact and shares practical treatment protocols, including using peanut butter as bait to locate nests. After lectures, he forms local WhatsApp groups to coordinate monitoring and treatment days and provide discounts on pesticides. Miron emphasizes collective, community-wide efforts, as treating only individual properties is ineffective.
The fire ant, one of the world's 100 most destructive invasive species, causes significant declines in native ant and invertebrate populations. It is active mainly in summer, thrives in humid areas, and can invade homes, stinging people painfully; rare cases of life-threatening allergic reactions have been reported. First detected in Israel's Jordan Valley over 20 years ago, it has now been found at more than 700 sites nationwide, primarily spreading through infected nursery plants. The Society for the Protection of Nature in Israel estimates the ant could cause annual economic damage of about 1.1 billion shekels if its spread continues.
Miron advises monitoring by placing baited traps with peanut butter or similar foods every few meters during mornings or evenings, then applying pesticide granules only in concentrated areas within a two-meter radius. He recommends covering baits to protect them from birds and repeating the process monthly from May to October, avoiding watering the area before monitoring. Successful treatment allows native wildlife to return within one to two years, except native ants, which take longer. Miron offers this method as a cost-effective, environmentally friendly alternative to broad pesticide spraying, which can cost thousands of shekels and devastate local ecosystems.
The 54th Annual Science and Environment Conference will feature further discussions on environmental issues and innovative research, taking place at Binyanei HaUma in Jerusalem on July 8-9.
