Is there a natural way to kill grub worms?

Question:We have tried poison from Lowe's, Home Depot several times and nothing is working. They are taking over our yard. It is not a fungus, just destructive grub worms. Is there something we can use or mix together that will kill these bugs? Help

Answers:
smash them. There are things that will kill them but you can thank the EPA for banning them in the US.
