Grub eradication - Nematodes?

We have had a bad grub problem for the past 2 years. The grass won't grow very well since grubs eat the roots, and birds dig up the lawn to get at the grubs. I've tried various forms of pesticides (granular, spray), with no success. Since we have a little one and spend a considerable amount of time in the yard, I am hesitant to use more aggressive pesticides.

I read about Nematodes (the helpful ones) and they seem (at least from what I have read) to be effective if introduced early in the spring.

So the questions are: Has anyone ever used Nematodes and what (if any) were the results? What other options are available?

PS - here is a site that sells them http://tiny.cc/XYuNE .

I used nematodes successfully 3 years ago:

I then followed up with Milky Spore:

Though I still find the occasional grub, the lawn is no longer totally infested.
This is a good thing. The japanese beetles that the grubs grow into were absolutely feasting on certain plants in my garden.
Easier to control the grubs than the beetles.

Good Luck

Reviving this thread because I think we've got the grubs -- our front lawn looks horrendous. Our back yard isn't much better, but I care a lot more about the aesthetics of the front lawn. Question for garden gurus: If you've got grubs, would it work to use the nematodes to only treat the front lawn? If you don't treat the back yard, can the little pests migrate back over to the front, thus causing the front lawn treatment to fail? Yes, I am totally clueless about gardening/landscaping despite owning a house with a front lawn and fairly large back yard for 10+ years...
