I have tried to understand why they face upwards when dead.. when u spray your house with anti pests control insecticides, the following morning you wake up to see all of them lying on their backs facing up, what do u think could be the reason for that?

Turns out that they breathe from there...and the insecticide asphyxiates them so they turn downside up to breathe easier. That's what my layman mind read somewhere tho'...Google woulda helped sha.

Because, dem don chop belle full sotey dem no fit lie down normal again..

I think, that happens when they are struggling for life/oxygen.. then no power to turn again, so you meet it dead upsidedown

Becos they r begging d sprayer for mercy

eyaa! Must u put it that way? Now u've got my emotions feeling bad for killing them. I don't kill rats, if i happen to catch any alive, one look into their eyes, I start feeling pity then release them to the streets.
