How not to store a Kindle while not in use

I am not good at English, so I didn't immediately understand the meaning of "How not to store".
It is so hard for the Amazon's customer service, too.
The first , what are the benefits of ants nesting in the electric device of the "Kindle"?
When the owner takes the kindle out of the bag at a cafe or somewhere, are ants going to get a tiny share of the spilled biscuit?

However, it was the only recently that I've found a line of ants in my kitchen at Waitrose's granola. I don't say much about other people.

I had no idea to freeze the kindle and kill the ants. I think it's disassembled and cleaned, but when I looked at the kindle I had, it wasn't a package that could be disassembled.
In any case, this can serve as a reminder to take good care of the electronic devices around us to prevent such incidents.
