Helping Keep A Healthy Lawn :)

[This review was collected as part of a promotion.] It seems like it will work well. I definitely recommend this Grub killer for anyone with a lawn that suffers from this pesky issue it is easy to spread via spreading device, the package has instructions for spreading and storage so no guesswork there. Waiting for proper results due to the inclement weather in Chicago it is somewhat difficult to gage efficacy throughly just yet however there is slight progress. I will be repurchasing once I have finished the bag.

Outstanding

[This review was collected as part of a promotion.] I’m so glad I decided to put this all over my yard maintain it Appearance does not bother me. Not that noticeable texture is great results. I’ve been noticing that it’s been working. You just have to be consistent with it but overall works great, especially for the summer. Keep all the pest
