Kimberly from Nashville writes,

Is Milky Spore okay if I have already used GrubEx and DE powder?

I have used the organic DE(for short) powder to control ants, etc. and have applied GrubEx also. I still have grubs, so I'm looking at Milky Spore, but see it should not be used with other products. Thoughts? I also want to make sure it will not harm my earth worms. Thank you.


Milky Spore can be used when other insecticides have been used but if you kill off the grubs before you use the Milky Spore than the spore will not have a way to multiply to kill off future grubs. Milky Spore will not harm earthworms.
