Need Watering Instructions

Still had grubs after first application. Just did another application. It would be helpful to have more detailed watering instructions for after the first 24 hours, particularly when applying in early November when I normally am not watering the lawn.

No moles

Used it last year after battling moles for 2 seasons. Still no moles. Getting ready to spread it again to keep them away.

IT WORKS!!!

My husband treated the lawn and within hours the grubs were surfacing and dying. We have a fairly small patch of lawn and he said there must be hundreds of grubs that surfaced. We hope that by killing the grubs that we will get rid of the moles and armadillos that are coming to feast on them, and destroying our yard.

Wonderful product to get rid of moles/voles

We have been using this product at our lake lot in central Wisconsin to rid our yard of grubs/moles/voles 100% the past 4 years with one application in the spring. Remove the food source and the moles & voles go elsewhere.

It did worked even before 24 Hours passed

My yard was dying, and I didn’t knew why, until I started to see some small holes and mounds of soil, I searched the internet and found it was because of mole crickets... I searched for a solution, and I found this product, I applied it around 6pm and watered it as indicated... next morning I can’t explain how many small holes I saw in my yard and how many dead mole crickets I found on the yard and curb. I don’t know about other types of pests...but this works 100% for mole crickets!

Did not work

I have a bad grub problem and the crows have been trearing up my lawn to eat the grubs, so i needed a solution to kill the grubs. I bought 10 bags of the bioadvanced 24hr grub killer to treat 40,000 Sq ft of lawn. I applied with a spreader, that night it started raining for 48hrs straight. At least a coule of inches fell. 1 week later I dug up 4 test patches and none of the white grubs were dead. I am very disappointed in this product and as I write this review the crows are laughing at me ...

Not as advertised!

I decided to buy this product after reading the reviews as I've got an area of grass that is full of grubs and I'd like to reseed before the winter season. I also consider myself fairly bright that can follow simple directions so I applied the granules and then watered the area per the directions. One day and a half later grubs are still littered throughout the lawn. I am going to apply again simply because I have no alternatives at this point and I will just consume the remaining granules I h...

[This review was collected as part of a promotion.] What a great product that gets the job done. It works really well. I mostly was concerned with ants and grubs.  I liked that it's easy to use by spreading it all over the yard and watering the lawn afterward. It definitely prevents damage to your lawn. It was so effective. I haven't had any problems even after just one application.

[This review was collected as part of a promotion.] This product is amazing! I had a huge problem with grubs destroying my lawn, garden, and flower beds. The product has simple instructions and was easy to use and apply, it doesn't have a harsh smell and did not interfere with other yard plants. I will definitely continue to use this one for further use.

[This review was collected as part of a promotion.] I am so glad that I tried Bayer- 24 Hour Grub Killer Plus Granules. This product started working the minute it hit the soil and it just seem to absorb into the ground quickly. It absolutely works and it is fast. My yard and home are Grub free and beautiful again, it seems that this year all the bugs are out early. I'm glad to have this product cause it works amazingly

Would Recommend

[This review was collected as part of a promotion.] Applied to get rid of grubs because armadillo have been tearing up our lawn and mulch looking for them. We tried using a trap but that may catch one armadillo bug others still come. So we applied this grub killer using a broadcast spreader. It works. No armadillo damage since last application. I will re apply this grub killer in another month.

Bye Bye Grubs!

Would Recommend

[This review was collected as part of a promotion.] Grubs are such a pain in the butt and getting rid of them has been frustrating till I tried 24 Hour Grub Killer Plus Granules. They are easy to use, just give the husband the bag and tell him to take care of it. LOL No really you just sprinkle it out and they do the rest of the work of getting rid of the grubs so you can enjoy your yard again.

No more grubs

Would Recommend

[This review was collected as part of a promotion.] I received this product to try and I'm happy that I did. I was planting a few plants for the spring and noticed more than a few grubs. I placed the recommended amount of granules and waited. When I went to finish my planting there were no more grubs. I call this a win for me. I always hate those things when I'm working in the garden.

Awesome product

Would Recommend

[This review was collected as part of a promotion.] I have used a lot of Bayer products but this grub killer is the best. It not only killed the ones already taking over the garden but it seems to be keeping the rest of them away. I like that it is not harmful to the plants and trees. The directions were so easy to understand that I had it done before my husband got home.

Great for the yard!

Would Recommend

[This review was collected as part of a promotion.] This was easy to apply in the yard. We followed the instruction and used a spreader. Our main issue are ants and grubs. We have so many ant hills in the backyard and armadillo holes. This helped keeping our yard in a better shape. A day after we spread this in the yard, we saw a bunch of dead grubs and ants as well. Hopefully our next step after this treatment is fixing the grass damage but I am glad I got the main problem taken care of. I high...
