Which is a better option for killing and controlling grubs
Dylox is used as a curative for grubs. It is only active for 48 hours. The active ingredient is Trichlorfon. Milky Spore will last in the soil for up to 10 years. This is a natural product made out of grub spores. We would recommend using Milky Spore if you are wanting long term control. This needs to be applied 6 times a year for two years.
