I know what grubworms are and where they come from, but has anybody used anything that worked in March instead of June/July. I know of Milky spore(expensive) and have 1 &1/2 acres to cover,watering in isn't an option for any product that has to be "wetted in". The armadillos are a problem so I want to take their food source away. I was told told to broadcast Turf ranger. I believe Turf ranger has to be put out maybe 3 times a year.Suggestions?

How about this - 14 or 15 bags should do the trick:

Spectracide at Lowe's: 14.35 Lb Grub Stop with Fertilizer

Most of the products I know of do require wetting in, but do you have to do that in your locale? In March/April in Carolina we spread it and let rainfall do the watering, or a heavy dew.
