Beetle grubs in garden #873372

Asked June 16, 2024, 9:06 PM EDT

I found beetle grubs in my raised garden. I’m not planting in said gardens this year, but have been prepping it for next year and it’s in essence two large compost bins. I have red wiggler worms in both for composting so I don’t want to add chemicals to kill the grubs and kill my worms as well, plus ruin good soil/compost. How can I safely remove without digging to find them?

As ugly as they are, they are common and rarely cause damage in gardens. No treatment is developed. https://extension.umn.edu/corn-pest-management/white-grubs#factors-that-increase-losses-1193311
