Reporter Dr Andrew Rochford has volunteered to check just how dirty cockroaches are in relation into a individual and also other matters We've got day by day contact with.
To get rolling, Andrew visits Liz Harry, a microbiologist in the College of Technology.
Liz will just take two swabs of germs. Firstly, a cockroach will run throughout a dirty surface area, including the kitchen flooring, and may then be still left for 2 hours prior to the swab is taken. Andrew's fingers will then wander across the very same area and he will not clean his arms for two hrs before his swab is taken.

Andrew's swab: There is a lot a lot more micro organism on the plate the place Andrew's hand was swabbed.
The cockroach is definitely cleaner than Andrew. Why? Simply because cockroaches in fact cleanse themselves fastidiously — on a regular basis.
"Most species of cockroaches are sort of like cats. Cats are regarded as a very thoroughly clean animal as it's normally grooming itself. And cockroaches do that also," states bug collector Darrin Vernier. He life from the US point out of Arizona and is nuts about creepy crawlies.
