The invasive Asian needle ant is a stinging, carnivorous pismire that has been slowly spreading across the US. Last year at least three cases of life-threatening anaphylactic reactions were reported in Georgia, making this little (and little-known) insect a growing problem. Asian needle ants will reach their yearly peak numbers in July and August. They are small and blend in so well that stings often occur when someone, perhaps while gardening or moving wood, unknowingly disturbs them. "Imagine somebody inserting a needle directly into your flesh," said one researcher. These ants are now widespread on the East Coast. For some, the stings can be life-threatening. For others, it's an unusual pain that can come and go for hours. Pet owners should be vigilant about where their dogs and cats venture to.
