Is it a snake that produces the almond smell as a warning?

I remember when I was young, my dad told me that if I smell almonds, get out of there, there’s a snake. He’s asleep now so I can’t call and ask but it’s really bothering me which snake it was. I want to say copperhead…? I got on this topic when my boyfriend and I were discussing how cyanide smells like almonds, which I knew from this story for some reason…
