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 ants are also rated at a pain level 3, including the giant bull ant and the Maricopa harvester ant.

Pogonomyrmex (sensu stricto) workers have the most toxic venom documented in any insects, with Pogonomyrmex maricopa being the most toxic tested thus far. [3] It has an LD 50 of only 0.12 mg/kg, compared to western honey bee venom, at 2.8 mg/kg, and comparable to cobra venom.

The Maricopa harvester ant inhabits much of the Southwestern United States and is believed to have the most toxic insect venom in the world. Humans may experience up to four hours of intense pain, while the equivalent of twelve ant stings is capable of killing a 4.4 lb (2 kg) rat. [73]
Pogonomyrmex badius workers transporting a seed to add to their granary Messor sp. carrying seeds into their nest. Harvester ant is a common name for any of the species or genera of ants that collect seeds (called seed predation), or mushrooms as in the case of Euprenolepis procera, which are stored in the nest in communal chambers called granaries.
