Ants are one of a beekeeper’s most common pests, both in the apiary and in the honey house. Florida and the southeastern United States have a large and diverse ant fauna, with both native and exotic species. The vast majority of ant species have no impact on our bees or us. This 8-page fact sheet written by William H. Kern and published by the UF/IFAS Department of Entomology and Nematology describes the few pest species can cause serious problems and suggests ways to control the ants for healthier hives.

Florida Carpenter Ants

They get their common name, “carpenter ant,” because some species excavate nests in wood. Carpenter ants are sometimes called bulldog ants or bull ants. However, not all species in the genus Camponotus are true carpenter ants because some nest in preformed cavities or in soil.

D) Antennal club 3-segmented. The pavement ant is one of the most commonly encountered ants in the United States. Since first introduced from Europe at the beginning of the nineteenth century, the ant has become well established and is prevalent in urban areas in the northern U.S. and parts of Canada. However, the extent of their invasiveness and severity as a pest is not well characterized.

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

Caribbean crazy ants with their brood. 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.
