When should I put GrubEx down?

When should you apply GrubEx in the Northeast?

Apply during spring or early summer to kill grubs as they develop. Using Scotts® GrubEx®1 Season Long Grub Killer annually can also help control Japanese beetle and Armyworm infestations.

Should I apply GrubEx before rain?

A very important tip is to water the grub control in within a few days. You can wait for a good rain heading your way, and apply the grub control before the rain. The chemical in some grub controls will break down in hot, dry weather. So if you leave the chemical on your lawn and not watered in, it won’t be effective.

Can you fertilize after applying GrubEx?

After applying GrubEx to your lawn, you do not have to wait to apply a straight fertilizer. However, you must wait at least one week to apply a combination weed-and-feed control product after applying GrubEx, and two weeks is preferred.
