Kev,

Mint shoots away again pretty quickly, why not just cut it back to ground
level so the grubs have nothing to eat - most moth larvae are very seasonal
so breaking the cycle with this generation should fix the problem - until
next year :-) Alternatively, not many grubs like white oil - make your own
with vegetable oil, detergent and water - ABC Gardening website had the
recipe.

Cheers,
Geoff

Hairy grubs (possibly white cedar moth larvae?) have eaten almost all

Can anyone suggest a non-pesticide solution to this problem?

Bacillus thuringiensis, sold as Dipel is a bacterium that is fatal to
grubs, caterpillers and apparently termites but is harmless to humans.
