Invasive Ants

Ants are common in places where people live. Everyone has seen and at least has some casual experience with ants. In many warmer parts of the world ants are much more familiar to local people. They occur in greater abundance and are more often found in homes and other dwellings. Most tropical and subtropical areas also have one or a number of invasive ants, i.e., species of ants that are notable for their ability to become human pests.

Invasive Ant Resources
There are a few excellent web resources that focus on invasive ants.

The best and most comprehensive website about invasive and introduced ants is | Antkey.org. The introduction to the site states: "Antkey is a community resource for the identification of invasive, introduced and commonly intercepted ant species from across the globe." There are keys, images, species accounts and more.

The | PIA Key is focused on invasive and introduced ants of the Pacific islands. It includes a key and excellent information about the species it covers. Many of the non-native ants in this region have also been transported to other parts of the world.

Recent Findings
The papers listed below are about or include information about invasive ants.

A study in French Guiana by Talaga et al. (2015) investigated the species of ants found in Aechmea aquilega in urban trees. They found baiting trees with these bromeliads detected more invasive ants than baiting other trees or on the ground.
