Can grub worms be dark green? We have no grass in our yard but used to. It has been dirt for two years now.

I need to find a treatment that is suited towards animals since our dogs have been eating them!
Bacillus thuringiensis (Bt) will interrupt a worms GI tract, killing them. It should be harmless to mammals. The following link has more information:
