I have never hadany problems with smells or rats and we live in a rural area. Yes, I have very occasionally seen a rat in the back garden ( 3 times in 25 years) but as the bins are at the front of the house, it is not that they are going for.
If I see a rat I put rat poison in the garden shed, which has gaps below the doors, too small for other animals and that deals with the problem.
Do you get emotionally attached to the plants in your garden ?
