Formicidae – EDIS Update

Integrated Pest Management (IPM) of the Tawny Crazy Ant, Nylanderia fulva (Mayr)

The tawny crazy ant infests buildings and greenhouses, attacks crops, domestic animals, and honeybee hives, displaces native ant species, and disrupts electrical equipment. This 8-page fact sheet describes how to identify the ant and monitor for infestations. It explains how to eliminate food sources and harborages and presents an integrated pest management plan and specific approaches to control this pest ant. (Note: the tawny crazy ant is a serious pest that multiplies quickly and can easily become an overwhelming problem. If you suspect you have tawny crazy ants, the best approach is to call a licensed pest-control professional for help).

Tawny Crazy Ant (previously known as Caribbean crazy ant) Nylanderia (formerly Paratrechina) fulva (Mayr) (Insecta: Hymenoptera: Formicidae: Formicinae)

Nylanderia fulva is part of a group of ants referred to as “crazy ants” due to their quick and erratic movements. It has been reported from 27 counties of Florida and 27 counties of Texas, as well as from Louisiana, Mississippi, Alabama and Georgia. Huge number of workers in infested areas can make human activities uncomfortable and difficult. They can infest sidewalks, buildings and gardens, and damage phone lines, air conditioning units and computers. They have killed honey bee larvae and used the hives as their nests, and are even displacing red imported fire ants where the two populations overlap in Texas.

Integrated Pest Management (IPM) of the Caribbean Crazy Ant, Nylanderia (=Paratrechina) pubens (Forel) (ENY2006/IN889)

Incidents of Caribbean crazy ant infestations are on the rise! These highly active ants are
annoying to residents and pets. And, they can cause short circuits and power outages if they infest electrical equipment. Learn how to identify and apply the principles of integrated pest management (IPM) to deal with these difficult pests in this 4-page fact sheet written by Dawn Calibeo and Faith Oi and published by the UF Department of Entomology and Nematology, July 2011.
