I live in a shop house, my below unit is rented to a restaurant, and hence rats are not uncommon in my house or my ceiling.
But for the purpose of this question, I just want to know how can I keep the rats away from wires/cables on my ceiling? My shop house suffered electricity outage a few times because the rats were chewing away the wires-- and electric short-circuiting themselves in the process.
I am thinking about calling pest control, but before that, I want to know whether is there any DIY solution or not.
