Q.Unexplained Mounds In Our Lawn
We have about 14 mounds/hillocks which have evolved in our back lawn over several years and are getting worse. They measure approximately 60cm diameter x 20cm height. Now they appear to be erupting in our front lawn. Any idea what is causing this and more importantly, how we can get rid of them! Thanks.

It could be mole or vole tunneling. In mole tunnels you can't see the entrance hole, but vole entrance holes are left uncovered. Groundhogs can leave holes a foot across.
