Aloha,

I'm seeking info on moles and grubs, namely:

Since moles are insectivores and don't eat my garden plants, is there any
reason I should try and eliminate them from my garden soil?  They take out a
plant or two if they tunnel through root areas, that's the only damage so
far.  Do they eat beneficial insects?  Naughty insects?  Both?

They eat grubs - what roles do grubs play in my soil?  Good, bad,
indifferent...?

If I wanted to keep moles out, what have people found to work (Pacific NW
USA)?  Noisemakers, castor oil, flooding, etc.

thanks,
John Schinnerer
