Most humans can withstand many stings, but others may suffer from severe reactions such as anaphylaxis. [45] People who are stung by red imported fire ants may experience intense local burning or flare-ups, followed by reddening of the skin at the sting site. This area will swell into a bump, hive or vesicle within 20 minutes. White fluid ...
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
Since most ants live on the ground, they use the soil surface to leave pheromone trails that may be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony.
A few individuals are sensitive to the venom, and can, on rare occasions, die of anaphylaxis. [3] In a survey of 29,300 physicians in the United States of America (in 1989), reports of 83 fatalities were obtained. [4] Some fire ant attacks on humans confined to beds have also been noted; in some locations, fire ants can be a particular threat ...
Ant keepers may choose to keep ants in captivity to document ant behavior (in the case of an ant species which is difficult to observe in the wild). This field of study is called myrmecology. Ant keepers may also choose to keep ants as a casual hobby; i.e., as pets. People who keep ants may also keep them for scientific purposes and experiments.

A worker can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. [1] The ant has an enormously enlarged mandibular gland, many times the size of other ants, which produces adhesive secretions for defense. [ 2 ]
Plerergates can live anywhere in the nest, but in the wild, they are found deep underground, unable to move, swollen to the size of grapes. [7] In Camponotus inflatus in Australia, repletes formed 49% (516 ants) of a colony of 1063 ants, and 46% (1835 ants) of a colony of 4019 ants. The smaller colony contained six wingless queens.
