Here's why:
* They have different waste systems: Insects like wasps have a different digestive system than humans. Their waste is often a semi-solid, not a liquid, and it's expelled through a different opening.
* They don't need to clean themselves: Wasps are covered in a smooth, waterproof exoskeleton that doesn't require cleaning. They can also groom themselves with their legs and antennae.
So, while wasps do go to the bathroom, they don't need toilet paper! 😊
