Cockroaches, for example, have been observed cleaning themselves after making contact with humans. And according to scientist Diane Ackerman, bats are pretty disgusted by us too. In her book A Natural History of Senses she tells a story about putting a large Indonesian flying fox in her hair, curious to see if it would get entangled in it. When placed on her head the bat began to cough, and once she set back it into its cage it spent some time licking itself clean of the smelly human odour.
