I've been reading up on the best ways to get rid of these little devils as well as 200 other garden pests.

Heterorhabditis Bacteriophora also known as Beneficial Nematodes (Steinernema Feltiae) are microscopic warriors that kill soil borne pests such as flea larvae, spidermites, fungus gnat, weevils, grubs, rootworms, cutworms, and many more. These Nematodes search, find, and kill pests living in the soil. They are extremely effective, and will reproduce and spread to provide you with long lasting organic pest control. Safe for plants, pets, and people. May be applied in a mulch, with garden sprayer or watering can. Unlike other beneficial nematodes, the Steinernema Feltiae only needs to be applied every 12 - 18 months.

It sounds like the best and most natural way to rid the garden of annoying bug type pests.

Has anyone tried this?
