Israel's Ministry of Environmental Protection has confirmed the first detection of the African big-headed ant (Pheidole megacephala) within the country. This invasive species is recognized as one of the world's 100 most damaging invasive species. The ant was initially identified in the Neve Sha'anan neighborhood of Haifa, specifically around Giv'at HaShaleshet and nearby streets, following reports from residents. Authorities are also investigating potential sightings in the Hadar neighborhood. The Ministry is collaborating with the Haifa Municipality, Tel Aviv University, and other professional bodies to map infestation sites, monitor the ant's spread, and develop strategies to curb its presence and prevent further establishment.

Originating from Africa, the African big-headed ant has spread globally, particularly in warm climates. Its name derives from the large heads of its soldier ants relative to their bodies. These ants exhibit a high capacity for reproduction and expansion, forming extensive networks of cooperating colonies that can include multiple queens. They are omnivorous, feeding on insects, seeds, and organic matter.

Similar to the invasive little fire ant, this species can expand its territory through the unintentional transport of contaminated potted plants, seedlings, soil, and garden waste. Its establishment poses a significant threat to local ecosystems by displacing native ant species and harming other arthropods, snails, and slugs. The ant also preys on small vertebrates like bird nestlings, shrews, and reptiles, causing cascading ecological effects such as disrupting seed dispersal by native ants. Furthermore, it can damage agriculture by fostering and protecting plant pests like aphids from their natural predators.

Identification of the ant involves observing numerous ants moving rapidly in dense trails. Distinguishing features include the presence of smaller ants alongside ants with disproportionately large heads, which are about one-third the ant's body length. The ants are brown, with lighter coloration in the center of their bodies and darker front and rear sections, measuring 2-3 millimeters in length, twice the size of the little fire ant. Nests are often found densely on the ground, sometimes surrounded by light brown dead ants. However, due to the existence of similar-looking native ant species, professional identification is necessary.

The Ministry urges the public, especially Haifa residents, to report suspected sightings with photos and precise locations to Pestcontrol@sviva.gov.il. Residents are also advised to avoid moving soil, potted plants, seedlings, and garden waste from suspected infested areas to prevent further spread.
