Japanese Beetle control not on calendar

Asked June 6, 2019, 10:27 AM EDT

Sorry if the calendar and corresponding insecticide recommendations for Japanese Beetle control are somewhere on your site which I couldn't find. The link to "Root Feeding" is a 404 error. https://extension.umn.edu/garden/insects/find/lawn-and-turf-insects/root-feeding/ Seems we're at the in-between stage of larval maturation now in early June. Am I too late? I have some granular Carbyrl, but before wasting it I hope to know your "best practice" recommendations at the moment. I can confirm the issue is Japanese beetle larvae consuming the roots of my grass. Thank you in advance for your help!

Thanks for the question. We are sorry that the link previously given you was not active.

Here are three active links that, hopefully, will answer your question. As you can see grub treatment at this time is not recommended and probably not effective:




Good Luck!!
