Little fire ants are wreaking havoc in Tahiti, New Caledonia, the Solomon Islands, and most recently, Hawaiʻi.
LFA are tramps: queen ants hitch rides in cargo to new areas.
Since an entire nest fits into a macadamia shell, traveling unnoticed is easy. Once they’ve arrived, they dominate, driving other insect species out. Separate LFA colonies don’t compete with one another; instead they form super-colonies blanketing the ground and foliage.
