Invasive Ant Species, Considered Among World's Most Destructive, Found in Israel

Israel has officially recorded the presence of the large-headed ant (Pheidole megacephala), an invasive species originating from Africa and recognized as one of the 100 most destructive invasive fauna on the planet. The first colonies were discovered by residents in the Neve Sha'anan neighborhood of Haifa, near Givat HaShabshab hill, and authorities are now investigating reports from the Adar area. The Ministry of Environmental Protection announced the findings, noting that the ant poses a serious threat to agriculture, infrastructure, and the natural balance by displacing local insect populations and preying on young birds and reptiles.

Joint efforts to contain the threat have been launched by government agencies, the Haifa municipality, the Nature and Parks Authority, and Tel Aviv University. Experts are mapping infested areas, tracking the ants' movement, and testing chemical control methods. While not a direct health risk to humans, the ants' aggressive behavior and ability to protect aphids can damage crops and green spaces. Their soldiers are characterized by heads that make up a third of their body length, and they form complex underground networks with multiple queens, facilitating rapid territorial expansion.

To combat the infestation, Haifa municipality and environmental officials have initiated a pilot program on four designated plots, experimenting with various insecticides. Ministry representatives are evaluating the results weekly to determine the most effective formula for Israel's climate. Residents have been urged to report sightings of dense ant columns and to avoid moving soil, cuttings, or potted plants from the affected zones, as humans are often vectors for spreading the pest.
