Put on a thick pair of gardening gloves, and begin pulling the onion grass out by the root. This is a laborious method to get rid of onion grass, and you might leave some bulbs behind that will grow new leaves. For the best results, use a trowel to fully remove the bulbs.
Mowing the onion grass will not kill it. However, consistent mowing makes the plants weaker and often prevents them from seeding. Mowing may also improve the uptake of a herbicide.
