The experts advise applying it in the first two weeks of July. The chemical will remain in the roots through fall, and kill any small grub. That takes care of your grub control until the next July. If you want a more fool-proof, season long grub control, use chlorantraniliprole.
When should grub control be applied in Michigan?
The preventive compound chlorantraniliprole should ideally be applied in April or May to control grubs that would be damaging turf in the fall as it will take longer for the material to move to where the grubs will be feeding in July. To kill grubs in the spring or fall, use carbaryl or trichlorfon.
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?
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. Easily apply with a Scotts® broadcast, drop, handheld, or Wizz® spreader and stop grubs before they damage your lawn.
How late can you apply GrubEx?
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. Animals may also continue digging for the insects.
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.
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.
Can I apply GrubEx on wet grass?
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 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 I apply GrubEx in summer?
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.
Is it too late to spray for grubs?
The best time to apply grub control is between early spring and late summer when there’s increased grub worm activity in your lawn. For grub preventers, apply between June and July just before they hatch while for grub killers, apply the treatment from spring when you see signs of grass damage.
How often should grub control be applied?
Grub control measures need to be taken on annual basis to work consistently. Skipping a year may be fine, but if any beetles have laid their eggs in your lawn’s soil over the course of that last year, you can be looking at a seriously damaged lawn by mid-fall.
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.
