I applied Grubex to my lawn on June the 3rd of this year. If I apply Milky Spore now, will the two products neutralize each other or has enough time passed that I can apply Milky Spore??
Milky Spore can be put down any time the ground isn't frozen, regardless of what other products you are using. However, if all the grubs have already been eliminated by another product, the spore will not have the ability to spread. If there are no grubs in the soil to consume it, it cannot multiply. The Grubex will not make the spore itself ineffective, it will just hinder the spreading process until more grubs appear.
