Dear Michele,
Thanks for reaching out! Here is a UMN Extension article on white grub control: https://extension.umn.edu/news/white-grub-control-lawns
The article states that treatments should be applied from late May to early August. You may wish to apply a short-lived, fast-acting, curative insecticide in August or September (options are given in the article). Treatments after early October are not effective and not recommended.
When applying the treatment, remember to read the label prior to use and follow the label directions attached to the treatment container you are using. The label is the law.
Good luck!
