This is urgent information for anyone planning to see the Pampas in Rurrenabaque, Bolivia:
Do NOT wear insect repellent containing Deet. There have been huge numbers of anacondas being found dead in the wetlands due to tourists wearing Deet and then handling them and touching their sensitive skin. Tour agents and guides are not taking the responsibility of warning tourists of this danger, so please pass this on! It's crucial to the delicate ecosystem and balance of the area!
