Pheromones are special messages that animals send to each other using smell.
Imagine you and your friend both have a favorite snack, like chocolate cookies. When you eat one, your friend can smell it from across the room and says, “I want some too!” That’s kind of how pheromones work, but for animals.
How Pheromone Types Work
There are different kinds of pheromones, just like there are different ways to send a message. Some help animals find each other, like when bees use pheromones to tell others where the best flower patch is.
Other pheromones let animals know about danger, like when ants leave a trail of “danger!” messages so other ants can avoid it.
Some even help animals know who their family is. Like how your dog might sniff another dog and say, “Oh, you’re my friend!” because they smell pheromones that tell them, “You belong to our group.”
So, just like you use words or actions to talk with friends, animals use pheromones, their special smelly messages, to talk with each other.
Examples
- Ants follow a chemical trail back to their nest.
