Longhorn Crazy Ants

Paratrechina longicornis (Latreille)


Longhorn crazy ants are opportunistic scavengers that will feed on a range of items including live and dead insects, seeds, fruits and honeydew. Foragers may enter homes in search of food and moisture, particularly during the cooler fall and winter months when natural food sources are scarce.


The longhorn crazy ant is not native to the United States. It is a tropical species with widespread populations found throughout most of the US. In southern states with tropical or subtropical climates, infestations can occur both indoors and out. In northern states that have a more temperate climate, longhorn crazy ants are more commonly encountered indoors.


Longhorn crazy ants do not pose a health threat, but if they gain entry to a structure, they can become a nuisance. If you notice Longhorn crazy ants, contact a pest control professional immediately to discuss a proper course of ant control.
