Fire ants also sting humans, Frye says, which can cause small pus-filled bumps on the skin, according to the Cleveland Clinic. Other symptoms: Ant bites are typically painful and itchy.
Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While the majority of Hymenoptera stings are locally painful, their associated venom rarely cause toxic reactions unless victims receive many stings at once.
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 ...
The stings of the red imported fire ant in animals are painful, and may prove life-threatening. [70] In dogs, stings from the red imported fire ant can cause pustular dermatosis, a condition where pustules appear in crops as a result of the ant sting. [71] After getting stung, the immediate response consists of erythema and swelling.

Symptoms of dermal exposure include numbness, tingling, itching, burning sensation, loss of bladder control, incoordination, seizures and possible death. Pyrethroids may adversely affect the central nervous system.
