It seems to be effective, although it can take several weeks to see a noticeable effect on those grubby little buggers. I put in a raised bed garden in the fall at a new home with trucked in soil due to the very thin layer of top soil over my basically limestone sub"soil" here in central Texas. After letting the heavily prepared soil sit over the winter I was ready for a great spring crop of veggies. I carefully planted my started-from-seed crops, picked just for this climate, only to see the healthy seedlings start to take off, then as soon as it warmed up they just stopped growing, withered, and some died. Spring was moving towards summer so I decided to bite the bullet and replace them with healthy nursery plants. I was horrified as soon as I dug out the first plant. The garden was FILLED with grubs. In a single square foot I sifted out 52 grubs. I pulled out most of the plants in the 4 raised beds as I hand dug through the beds sifting out all grubs that I could see. It was like an Alfred Hitchcock movie! The Mocking Birds even quit coming to take the grubs out of the plastic bin that I was throwing them into once they filled up! Well I also found them in very high populations in my ornamental beds around the house and knew I needed to take drastic measures. I didn't want to use chemicals in my garden, since the whole purpose of that was to have organic vegs. It was early April, so still barely cool enough here to put down nematodes, which I did. Unfortunately there are mixed results with grubs and nematodes so I was still doing a lot of research and came across reports on Milky Spore. Milky Spore is ingested by the grubs and the spore multiplies inside of them, eventually taking over the entire grub organism, killing it. The dead Milky Spore filled carcass is what propagates the Spore in your soil. So the more grubs that are infected and die from the infection, the more Spore you will have in your soil. This is how it stays effective for so many years. In theory you will continue to have grubs, but the ones you do have (from beetles that fly in and plant their eggs in your inoculated soil) will never be healthy, and will never develop in to beetles. I decided to go for it and treated my garden, then later my ornamental beds and yard. Well, during that summer I continued to periodicity dig around in my garden and I did in fact notice that the grubs that I was pulling out were increasingly less active, despite it getting hotter, and I also pulled out several pure white grubs that while apparently alive were not active at all. Normally when you throw a fat grub on top of the hot May soil its actively digs back into the ground. These hardly moved. I promptly squished my little inoculants and stuffed them back into the soil. Haha! In the subsequent two years there have been fewer of the little buggers seen when I have been planting, and they have been smaller, and my garden has been as productive as it can be with the drought we have been in. I still see occasional lethargic, small, all white grubs, and I am happy to see them, knowing that they are spreading the good stuff in my soil (that is as soon as I squish their little heads and stuff them back into the dirt, bah ha ha!).
