Bonjour Pixi! Nice to hear from you again!
Moles are feeding on the bugs underground, which is why they are digging nice tunnels and hole in your lawn.
There is a product over here called Mole Repellent that is actually clay granules impregnated with castor oil that you sprinkle around. You can also get it as a spray. It is safe for the environment, and doesn't harm the moles. If you can't find the product over there, maybe try using a spray bottle with castor oil in it and spraying with it. You would have to repeat this every once in a while because of rain, etc.
There is also another product called Shake Away, that is made from organic fox and bobcat urine powder, that makes the moles think there are predators nearby. It is all natural, and non-toxic, safe for plants and pets and the environment.
Also, moles cannot stand vibrations or noise in their underground tunnels, so if you run a fan or something that causes vibration where they are tunnelling, they should move out.
I hope you're able to try something from these and get rid of those beggers! Good Luck! Bonsoir
