Hi Peter,Is it too late (September 13th) to kill grubs this year? Should I just wait until next summer? Thanks for your advice!
This late in the season you’ll have to resort to the contact killer from Bayer called 24 hour Grub Control. Apply it and water right after with 1″ of water…don’t count on rain, it wont be enough. Next year apply Bonide Annual Grub Control in July and water that in with an inch of water. It is more effective that the contact killer and is a safer chemical to use.
