rat repellent?

my garden has suddenly become a feeding place for rats, they are actually climbing up a steel pole to get onto the bird tables, i love all sorts of wildlife normally and am reluctant to kill these rodents, so, has anyone got any good remedies for repelling these rats? i have heard of a few but are they just old wives tales? kind regards to all, and happy new year.

Controlling rats is actually quite straightforward. As with most pests, they come to seek warm shelter and food. Overfeeding birds is a common means of attracting rats, so use a bird table with a rat-proof support if possible (or instead of feeding birds, put out a birdhouse or birdbath). Make sure dustbin lids fit tightly and compost heaps are isolated and well-contained. Ongoing prevention can be also be the use of pest repellers which use electromagnetic and ultrasonic sound waves to ward off the rats. You can install these like smoke detectors around the garden to create a no-go zone.
