Milky Spore Disease , "Bacillus popilleae", is a passive grub control that must be ingested by the grubs but is spread around as they die greatly enhancing what you put down. The package should have instructions on application that will be something like put a teaspoon of the powder, or grains, every 4 feet in rows 4 feet apart. Once either is applied, neither is better than the other, it needs to be watered in and now is a good time to apply it since the grubs will be hatching from the eggs laid last month soon and the best time for control is while they are quite young.

Thanks very much, Kim. I'm going to order some right away. I wish I knew how much of our yard my husband treated to get such good results. We have quite a lot of mowed area; I doubt he did the whole thing, but I have no idea.

Alisande, I'll emphasize kimmsr's statement that you read the instructions on the particular MS formulation that you end up getting. Some of the granulated formulations are packaged with a large volume of inert product so that the spore can be applied with a drop spreader, applied in a grid pattern.

There is no single method that will be suitable for every brand of MS....but I can assure you that the directions that come with the product will make it all clear for you.

Let me know if I can help!
