You need to apply a curative application during the summer when the grubs are small and actively feeding near the surface. Depending on where you are located in Pennsylvania, this could be from August through mid-September.
When should grub control be applied in PA?
Preventatives take about 1 month to systemically reach your grass roots and to be present for grubs to feed on. Because of the early start to spring this year, it is recommended to apply grub control anytime now through Mid-June for the Western PA region.
What month do I apply GrubEx?
Because GrubEx targets the larval stage of many insects, the best time to apply it is when the beetles burrow into lawns to lay their eggs — in spring to early summer. When the eggs hatch, GrubEx kills the emerging larvae so they cannot develop into mature insects.
When should I apply GrubEx to my lawn?
GrubEx works as a preventative by preventing eggs from maturing and hatching, so you want to apply it late in the spring and be sure it is present in the soil through mid-summer. One application can last for about four months.
Can I apply GrubEx and fertilizer at the same time?
According to the Scotts website, only straight fertilizer, with no other ingredients such as pre-emergent herbicides or other pesticides, may be applied at the same time as GrubEx. Fertilizers mixed with other products such as crabgrass control may be applied two weeks before or two weeks after using GrubEx.
Can you apply too much GrubEx?
Applying too much can hurt the environment and using too little may not control the grubs in your lawn. Although Dylox claims it kills grubs within one to three days if applied properly, you may still notice grub activity within that time or shortly after.
Is it too late to treat for grubs?
Treating in late summer or early fall is ideal, as that is when the smaller, young grubs are most susceptible to nematodes. There is also usually a short window for application in early spring before the grubs get too big and pupate, but that is a narrower window and can be difficult to time properly.
Can you apply GrubEx to a wet lawn?
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.
Will grub damaged lawn grow back?
If you have areas of dead turf, you’ll need to re-seed them. Some areas will need to be scraped clean, soil added, and seeded. However, some areas may just warrant slice-seeding to repair them. Either way, they aren’t coming back on their own.
Will GrubEx get rid of moles?
Moles feed on soil-dwelling insects, especially grubs. You can eliminate this food source by using beneficial nematodes and milky spore to kill the grubs in your soil. The application of milky spore may take several seasons to become effective. Gophers eat vegetation, so grub killers will not get rid of them.
Can I treat for grubs in the spring?
To kill grubs in the spring or fall, use carbaryl or trichlorfon. Always wear rubber gloves and rubber boots when applying insecticides to turfgrass. Make sure to irrigate the lawn with at least 0.5 inches of water* and allow the grass to dry before allowing anyone or pets into the treated area.
Can you put grass seed down after GrubEx?
Can I put grub-killer and grass seed down at the same time? If not, which one should I do first? A: There’s nothing in grub-killers or grub-preventers that’ll hinder grass seed. So yes, you can do both at the same time.
What do grubs turn into?
Lawn Grubs, often called White Grubs, are the immature form of different Scarab Beetles, such as Japanese Beetles, June “bugs” (beetles) or the European Chafers. A white grub eventually turns into adult Beetles and emerge from soil to mate and lay eggs.
Can GrubEx be used in flower beds?
Yes, you can apply GrubEx to the flower bed. It won’t hurt your flowers. Use the same rate as the lawn, and water it in after applying. Grubs can do root damage to plants other than grass and can be found in garden beds.
Do grubs come back every year?
All lawns, everywhere, have some grubs every year. Newly hatched grubs are big eaters! Grubs eat the most in the Fall and progressively less as they mature in the Spring. In fact, when grubs are nearly ready to change into beetles, they stop eating.

Is July too late for GrubEx?
The best time to apply GrubEx is late spring to early summer. You may see some reduced control with an application in late summer, however reducing your grub population this fall and next spring would be better than doing nothing. It is best not to apply to waterlogged soils.
How soon after treating for grubs can you plant grass seed?
Before you can seed, you should wait until the grubs pupate into beetles and fly out of the ground. That will be when soil temps get consistently around 70 degrees.
