I have tried las summer to catch some of them who are playing under the lawn. This summer is the same situation. I have bought Latvian mole traps and will show how it works. Last summer result is 1:0 – my best. This summer 0:0.
I am using this kind or traps. This is not active position for trap
Exume molehill and find highway
This trap should be set in the middle of the highway
