We have been plagued by moles in the yard for the past several years.
The doobers try to dig them up, but are not effective at totally eradicating the population.
Were were told to kill the grubs with chemicals so that the moles would starve to death or leave, but we have way too much yard to cover and don't like the "chemical" solution anyway.
To make matters worse, the doobers hunt snakes thus minimizing our best natural control.
I determined that if we were going to get the upper hand on the mole problem, we were going to have to take alternative action.
Here is a picture of the kind of damage done by the doobers trying to dig up a mole.
(You may have to tilt your head a little to see this picture correctly.)
Nevertheless, you get the picture. Moles, doobers, and yards don't mix.
I decided to find a good book on mole eradication.
