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 ...
These ants release a complex venom mixture that can include histamine. Within the subfamily Formicinae, the stinger has been lost and instead the poison gland forcibly ejects the fluid of choice, formic acid. [8] Some carpenter ants (genus Camponotus) also have mandibular glands that extend throughout their bodies. When these are mechanically ...
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.

The toxicity of the venom of the Maricopa harvester ant is well known. Its LD 50 value is 0.12 mg/kg (injected intravenously in mice); 12 stings can kill a 2-kg rat. In comparison, the LD 50 of the honey bee is 2.8 mg/kg—less than one-twentieth as strong. In humans, a Pogonomyrmex sting produces intense pain that can last up to four hours. [3 ...
Some soldier safari ants make tunnels to provide a safe route for the workers. Seasonally, when food supplies become short, they leave the hill and form marching columns of up to 20,000,000 ants, which constitute a considerable threat to humans, though they can be easily avoided as a column can only travel about 20 meters in an hour.
