| I am confused about what is best for the lawn. I have a mole problem and I have been told to use a grub killer to get rid of them. But don't you need some grubs for healthy soil?
|Moles do eat a variety of soil creatures including slugs, grubs such as those of Japanese beetles, and other insects. Moles -- and other soil life -- help to aerate the soil, allowing ways for air and moisture to pentrate the ground. Moles can in some ways be considered an indication of a healthy soil. Since moles do not eat plant roots, they do not need to be controlled unless their tunnels are causing a safety problem to people walking on the lawn. (If you are seeing tunnels along with severe plant damage, with roots being eaten, then your problem is more likely due to voles.) You would not want to use a grub control product unless there is a severe grub infestation that is causing significant damage to the lawn.
Here is additional information about moles and voles you may find interesting.
I hope this answers your question.
