Invasive African Ant Species Detected for First Time in Israel

The Ministry of Environmental Protection has confirmed the first-ever presence of the invasive African big-headed ant (Pheidole megacephala) in Israel. Following resident reports, the ant was identified in the Neve Sha'anan neighborhood of Haifa, specifically around Giv'at HaShahashet, with ongoing investigations into potential sightings in the Hadar neighborhood. This species is recognized as one of the world's 100 most damaging invasive species.

While not a direct threat to human health, the ant possesses a high reproductive and dispersal rate, posing a significant risk to agriculture, infrastructure, and local ecosystems. It displaces native ant species, preys on small vertebrates like nestlings and reptiles, and cultivates aphids that harm vegetation. The soldier ants of the colony are distinguished by their large heads, approximately one-third the length of their bodies, and their brown color, measuring 2-3 millimeters, twice the size of the common fire ant.

In response to the identification, the Ministry of Environmental Protection, in collaboration with the Haifa Municipality, the Nature and Parks Authority, and Tel Aviv University, has launched an initial pest control pilot program in four affected areas within the city. This initiative includes weekly monitoring and surveillance.

Dr. Shay Reichler, Director of the Pests and Pest Control Department at the Ministry of Environmental Protection, emphasized the need for "professional, systematic, and rapid action" upon identifying a new invasive species, to prevent its establishment and spread. The Ministry urges the public to report any suspected sightings and to avoid moving soil, seedlings, or green waste from affected areas to curb further proliferation.
