>>I am in India and we have a team that cleans up after work because we can have food at our desks and any food left out attracts cockroaches and mice/rats.

Where do you work in India?

If your office infrastructure is so broken that you could have mice infestation, you definitely have far bigger problems than eating at your desk. In fact at this point in time, I'd like to think you have a mice infestation already.

At almost any major tech park that I've worked in Bangalore, I can't recall even single instance of even seeing a fly or mosquito in office. Let alone see a rat.
