How to Treat Grass Grubs and Porina in Your Lawn with NZLA Grub+

Hi team,

I suspect I have some pest activity in my lawn, I know there is the odd grass grub in the root zone but I am also seeing little holes in the dirt which I think could be Porina.

I understand that using Grub+ to treat grubs requires the product to be watered in “immediately” and for treating surface pests the directions are to delay irrigation for 24 hours.

If I want to treat for both pests can I spray it on, wait 24 hours and then water it in to treat the grubs, or do I need to put a second application down the next day to water in for the grubs?
