The Schmidt sting pain index

Ever wanted to know what a bullet ant sting feels like, without putting yourself through the pain? Wondering what’s worse, the sting of a fire ant or warrior wasp? You’ve come to the right place.

Entomologist Justin Schmidt recorded his own experience of venomous stings, to rate and describe the pain caused by the venom of insects. Explore part of Schmidt’s pain index below.

Schmidt’s pain scale runs from one to four, with four being the most painful.

Pain level 1

Red fire ant, Solenopsis invicta

“Sharp, sudden, mildly alarming. Like walking across a shag carpet and reaching for the light switch.”

Tropical fire ant, Solenopsis geminata

“You should have learned, but the carpet is the same, and when you again reach for the light switch, the shock mocks you.”
