    Pulling them up, bulbs and all (can use a spade) is most effective.

    It's actually garlic but best option may be pulling or digging up. You have to find that bulb to stop it. Since you have to put up with them you could use the tops n salads or whole thing in place of onion or regular garlic.

    If ever there was a plant made to survive weed removal methods, wild onion is it. For these reasons, wild onion control needs to be a done with a combination of methods. It is best to take steps to get rid of wild onions in the spring, before the plants have a chance to go to seed, or in the fall, which will weaken any surviving wild onion plants, making it more difficult for them to survive through the winter. Killing wild onions starts with removing as much of the clump of wild onions as possible. Do not try to pull the clump of wild onions out of the ground. The small bulblets are designed to pull away from the mother plant when pulled, which leaves extra bulbs in the ground that will rapidly regrow. Instead, dig the clump out of the ground with a spade or a trowel. Throw the entire clump away. Do not try to shake excess dirt off back into the hole and do not compost. If you do, this will only respread the wild onion bulblets back into your garden. The next step to kill wild onions is to treat the area with either a non-selective herbicide (like Round-up) or boiling water. Both boiling water and non-selective herbicide will kill any plant it touches, so keep this in mind in regards to surrounding plants. After removing the wild onion plants, keep a close eye on the area and repeat the process if any new wild onions start to grow. Due to the hardy break-away bulblets, you can expect that they will grow back at least one time.
