Yes, grubs can be good for gardens. They give structure and texture to soil by opening up air and water pore spaces through their underground activities. They may add to nutrient availability and soil fertility through their decomposing bodies and serve as prey within food chains.
There's a good chance it would but it probably isn't a good idea. It's a dangerous substance and would greatly lower the pH of the soil, possibly causing more damage than the grubs.

Good Thanks... Occasionally makes a good meal.
A grub is basically the baby of an insect. A good example sentence would be, the garden was crawling grubs.
Bulldozing, controlled burns, mowing, soil drenches, and solarization are ways to get rid of grubs, weeds, and worms at the same time. A combination of controlled burns, soil drenches, and weekly mowing generally controls pathogens and pests within a year. Bulldozing and solarization with weighted-down black plastic sheeting makes the soil inhospitable to pesty soil food web members.
why would you want to when they improve the soil ? There are other wormlike creatures that are grubs, and you would want to carefully eradicate those by picking them out of the soil. If you use a pesticide, you risk killing the earthworms which are beneficial to your soil.
