this may confirm the answer http://sitemaker.umich.edu/ling111ec/pheromones `"Pheromones are chemicals released by living organisms that send information to other organisms of the same species via scent. These pheromones are released in response to stress, alarm, danger, and sexual fertility. They are released by both insects and mammals in many situations."`
