[No maps are yet available for little fire ant locations on this island.]

NOTE: "Wasmannia recently found on Kauai at one locality but may already be eradicated (they probably got it quickly)" -F. Kraus, 05Nov1999, pers. comm. to PT; "Wasmania was located and, hopefully, eradicated on Kauai. Contact is Guy Nagai with HDOA, Kauai." - D. Nelson, 08Nov1999, pers. comm to PT.

Other Hawaiian islands

Little fire ants are not known to occur on Hawaiian islands other than those listed here (as of November 1999). It is very important to report new observations of ants on these islands, so appropriate measures can be taken to stop their spread while there's still time!!
