Chimpanzees 'keep their beds cleaner than humans' because they build complex tree nests out of branches and leaves which contains less bacteria than most households

Chimpanzees keep their beds cleaner than humans, scientists have discovered.

The great apes build complex tree nests out of branches and leaves in which they sleep. And they set an example the average human teenager would find tough to follow, according to Daily Mail.

In fact chimp forest nests contain fewer body bacteria - such as those shed from the skin - than beds in most human households.

PhD student Megan Thoemmes, who led a team collecting swab samples from 41 chimpanzee nests, found the chimp nests had a much greater variety of bugs - a finding that was not unexpected in tropical forests.

However, they were far less likely to harbour ‘dirty’ bacteria from the mouth, skin or elsewhere in the body.

‘We found almost none of those microbes in the chimpanzee nests, which was a little surprising,’ said Ms Thoemmes.


The scientists were in for another shock when they tried to vacuum up parasitic arthropods - fleas and lice - from the chimpanzee nests.

They expected to find hoards of the bloodsuckers, but collected no more than a handful.

Ms Thoemmes said: ‘There were only four ectoparasites found, across all the nests we looked at. And that’s four individual specimens, not four different species.’

She added: ‘This work really highlights the role that man-made structures play in shaping the ecosystems of our immediate environment.

‘In some ways, our attempts to create a clean environment for ourselves may actually make our surroundings less ideal.’
