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.
Like wasps and bees, ants are social and live in a colony with one or more queens. That means the workers have to keep finding food to keep everyone alive. That means the workers have to keep ...
[32] 51% of people who relocated themselves to infested areas report getting stung within three weeks after arrival. [33] In a survey conducted in South Carolina, 33,000 people (or 94 per 10,000 population) received medical attention due to red imported fire ants, and 660 people (1.9 per 10 000 population) were treated for anaphylaxis.

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 ...
They usually stay outdoors in the garden, living in massive social colonies where everybody has a job, from finding food to caring for the queen. Until they don't. Until they don't.
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.
Don't let these pesky kitchen guests take over your space.
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 ]
