Chlorantraniliprole (Grubex) is a preventative and has a longer residual.
Trichlorfon (Grub Killer) is a curative and has a short residual.
In other words Grubex lasts a long time in the soil and works slowly to get rid of grubs. Grub Killer is like spraying a spider with a bug killer, it will kill them quickly and then dissipates. It will pretty much kill everything in your lawn that comes in contact with it - ants, worms, crickets, earwigs, etc.
Now like my wife always tells me, answer the damn question.
You can put the grub killer down after the Grubex.
