I really don't much mind moles-they do not seem to last long. We just moved to a new fixer-upper, the yard has not been worked by humans for over 5 years-but the moles have worked it!, every ft. Or so was a mound.. After tearing up all ridicuosly over grown ivy, ferns etc we did use grub killer as a way to lessen the food source, however, with the amount of vegetation in the river behind us I am certain we will still see mole holes as they make their way to where they go.
I am trying to plant some plants that deter bugs, such as marigolds, and walkable groundcover,and my favorites I will put in pots. All herbs we built tall above ground boxes for, and my vegetable garden will be well above ground next year.
What I have found by digging around fresh moles holes are certain types and substantial amounts of grubs-I worry more about the grubs feeding on roots of my new in ground shrubs, trees and plants than I do the moles and since I am not bothered by the moles themselves and will follow them in finding where grubs may lie beneath the surface which I could never know or find on my own.
The moles can stay as far as I am concerned both to loosen the soil and police the grub and bug population! Our side lawn I changed to pea gravel and pavers, and will have very little actual lawn-My neighbors can fight moles-I will welcome them.
Because they eat grubs in the roots of plants which damages the plant causing it to die
Moles can burrow deep into the ground and this helps to mix soil nutrients as well as improve soil aeration and drainage. They also eat many lawn pests like crane fly larvae and slugs. Yet they are classified as pests and often sought after and exterminated. This is because the damage they cause far outweighs the good that they do.
They generally burrow just below the surface of the earth leaving long telltale mounds all over an otherwise impeccable lawn. Earthworms that are very beneficial to the soil, unfortunately, make up their staple diet. They do not hibernate and work day and night all the year through. They have a high metabolic rate which therefore means that they have larger appetites which also means that more earthworms get eaten. They cause extensive damage to valuable root systems of decorate (and probably expensive!) plants causing them to wither and die. They often eat the grubs nestled in the roots of the plants and damage or even kill the plant in the process.
