Are we talking formic acid from crushed ants or just there is an ant around and they can smell it?

Not just crushed ants, I smell it when they're scared and running, but undamaged, as well. Calm ants though, they don't smell to me. I always assumed it was a warning chemical to other ants, or a deterrent for predators with more sensitive sniffers than I.

Exactly, ants literally spray formic acid at anything that threatens them

I smell it either way but it's stronger when they're crushed.
