I have a mole at the top of my garden. The first hill appeared about 10
days ago and the second, nearby, a couple of days ago. Both in lawn.

What should I do? Our garden is intended to encourage wildlife but hills
all over the grass doesn't seem to me to be a friendly hello from a
visitor. Do the sonic repellents work or do I have to insert a trap in a
tunnel and take it far away?
