The smell of rain as it drops on the parched earth

Posted by Robin on 17 December 2019 2 Comments

Geosmin is one of the most recognizable and common microbial smells on the planet, and scientists from FIU, Lund University and University of Washington have discovered the organic compound is particularly appealing to mosquitoes looking for a place to lay their eggs.

“It’s the smell of rain as it drops on the parched earth,” said FIU biologist Matthew DeGennaro, who was part of the team that made the discovery. “We now know geosmin is part of the story of how mosquitoes breed.”

    Is this chemical another name for petrichor? Even if not, some of might want to rethink our fragrance choices for outdoor wear! https://en.wikipedia.org/wiki/Petrichor

      Geosmin is part of the scent of petrichor, yes. It’s the earthy part, then for the scent after rain you’d add ozone & possibly plant oils.
