Earliest known bug-repellant plant bedding found

Seems that these people in South Africa were bedding their shelters with plants known for their insecticide or repellant properties 50.000 years ago.

Interesting but not surprising at all- many animals today, including some not usually considered as very smart- know about medicinal and insect-repelling plants. Apes and monkeys are famous for treating their own illnesses with medicinal plants, but there's also harpy eagles and starlings, among other birds, lining their nests with insect-repellant and insecticide plants to protect their chicks from parasites, pretty much like the people mentioned in the article.
