Acanthomyops, also called citronella ants, is an ant sub genus that releases alarm pheromones with a "lemony" or citronella smell when they are disturbed.[1] These pheromones, which are composed of terpenes, hydrocarbons and ketones, are released from its mandibles and Dufour's gland.[citation needed] The worker's response to this chemical is raised antennae, followed by opened mandibles and running in the direction of the pheromones source (Hughes et al. 2001).

Some species, referred to in the United States as "moisture ants", make nests in and around rotting wood.[1] They can infest buildings, becoming a minor nuisance. They are not considered a structural threat because they make galleries only in wood that is already decayed.


The sub genus included the following species:
