Which Smell Repels Mice and Rats in the Home
Rodents rely on an acute sense of smell to locate food, recognize conspecifics, and detect threats. Olfactory receptors in the nasal cavity transmit chemical signals to the brain, where they are processed for immediate behavioral responses. Food odors trigger foraging, while pheromonal cues guide social interactions such as mating and hierarchy establishment.. Date latest changes:
