Grub Control

Ware · Apr 15, 2017

If you plan to use Scotts GrubEx for preventive grub control, now is a good time to apply it. This MSU article states that its active ingredient (chlorantraniliprole 0.08%) should be applied between April 1 and May 30 for best results. This is a couple months earlier than the recommended timing for some other active ingredients/products.

What does everyone else use (if anything) for grub control?

I try to drop the new version of GrubEx around April 15th. Apparently the new AI works better and is less harmful to bees.

I spray Imidacloprid (ImidaPRO 2SC) every 3 months to keep them under control.

Imidacloprid is one of the ones mentioned in the article that is best applied in June or July to control newly hatched grubs. They say none of the preventives like chlorantraniliprole or imidacloprid are effective on larger grubs that are found from September to May.

I've had good success with it even after an infestation. All I know is that I spray that stuff down and grubs come crawling out of the ground after irrigation or rainfall.

did you use it recently... I don't like those guys ... it's like a damn mine field going to take Titan out back to his spot

I put out Milky pore last spring...supposed to last ten years! We shall see!

How has that treatment worked for you?
I did the same last fall and while I know that’s not an immediate curative application, I am still finding grubs in the lawn and flowerbed this spring as I move some plants around the landscape.
What state are you in

Thanks that's good to know. I plan on putting in some bee houses to help them and my garden. Is there a good way to know the new version?
Thanks!

Chlorantraniliprole is the newer AI. Here's a link about it with bees.

Great thanks!!

Permitherin seemed to do the trick for me last year. I had a small infestation of grubs and I also had army worms. Both handled well by Permitherin.

FescueFanBoi · Apr 2, 2025

Interesting. How long does it last ? I need to make sure the fleas and ticks are also killed in the yard

What about an active infestation of grubs, right now, where I have freshly scraped grass off of and plan on putting sod down?

Greendoc · Feb 7, 2019

Dylox.

From what I have read, trichlorfon (Dylox) and carbaryl (Sevin) are the go-to AI's for curative grub control.

Correct. Carbaryl is no longer allowed on residential lawns except as a spot application? How does one spot apply knowing insects are going to eat most of the lawn?

SCGrassMan · Feb 7, 2019

Carbaryl is allowed in my state. Guess I will plan on getting a bag of each. Which sucks for like <900 square feet. Was hoping you were going to say bifenthrin lol

Greendoc · Feb 7, 2019

Make sure it is Carbaryl. I saw bags and bottles labeled "sevin" that were actually Zeta-Cypermethrin.

What's the stance of Chlorpyrifos in the states?

Looks like it was banned for home use in 2001 but farmers and golf courses can still use it.

tomartom · Feb 8, 2019

I use it here in Aus, long pants, gloves mask and goggles though. I will probably move away from it though when I finish the bottle.
It is broad spectrum, and has some residual

Anything else that can be used that doesn't cost $160-$180/bottle?

Just exploring options before investing into a 2.5gal container of product.

just curious as to what grub control product you have found thats $180/bottle? chlorantraniliprole is only $40 at Lowes/HD and one bag should cover your 4k of lawn

FescueFanBoi · Apr 2, 2025

What product are you buying at Lowe’s

Dylox is $180 and I found the Bayer Sevin SL or whatever for $130/bottle.

@iFisch3224 dylox is a curative product. You use it to kill the big live grubs. It last a few days in the soil. I don't recall Sevin being good for grubs.

Chlorantraniliprole is a preventive product. You apply it in spring and it stays in the soil for a few months. When the insects lay eggs in the summer, the product prevents them from developing into grubs. This way to prevent the cycle.
