Just like us, microbes are living things, so they need food, drink and warmth. To control microbes you can therefore -
:: take away their food,
:: take away their drink, or
:: take away their warmth.
We also know that microbes like to travel. So to control them, we can stop them travelling -
:: by air, or
:: by touch.
Simple, isn't it?
Now have a look at some of the microbes. They are really quite pretty!
