Imagine you're playing hide-and-seek with fleas. Some people are like a big, bright light, easy to spot and catch. Others are more like shadows, hard to find. This is because of how our skin smells and feels. Fleas can sense body heat and carbon dioxide, just like we can sense the smell of cookies from across the room. If you're sweaty or have a lot of hair, fleas might think, 'That's my next meal!'
Examples
- A kid who loves running outside is likely to get bitten by fleas after a game of tag.
- People with hairy legs might find fleas hiding in their leg hair like tiny hideouts.
