I agree that Beer works well. Place shallow trays (about 1- 2 cm) with
vertical sides in the garden and fill with beer. Pick the dead ones out or
pour them out and refill every few days. Drink what will not fit in the
trays.

I have also had good luck with Diatomaceous Earth. It works well here
during the dry season. It must be replaced after each rain, so I don't use
it as often in the spring.
