Will spreading diatomaceous earth on a lawn get rid of grubs?

Yes, spreading diatomaceous earth on a lawn can help control grubs, as it acts as a natural insecticide. The sharp particles of diatomaceous earth damage the exoskeletons of insects, leading to dehydration and death. However, it’s most effective when applied directly to the areas where grubs are found and may need to be reapplied after heavy rain. It's important to note that while it can reduce grub populations, it may not eliminate them entirely.
