How to Get Rid of Onion Maggots (Natural & Organic Methods)

By Sabrina Wilson / August 1, 2022

Onion maggots are the larvae of the onion fly. They are white or transparent, and have a black head. They are about ¼ inch (6 mm) long when they hatch, and grow to be about ½ inch (12 mm) long. They are found in the soil near onion plants.

Onion maggots damage onion plants by eating the underground parts of the plant, including the bulb. This can make the plant dried out and stunted. If enough maggots are present, they can kill the plant.

Onion maggots can also spread disease from one plant to another. They are especially fond of onions that are already sick or rotting.

Maggots can be controlled by using pesticides, but the best way to control them is to prevent them from getting into your garden in the first place. You can do this by using a wilt-resistant variety of onion, and by keeping your garden clean and free of debris.

Experts suggest that when you're trying to get rid of onion maggots, natural or organic methods are preferable. Here are some reasons why:

1. Natural or organic methods are less likely to harm the environment.
2. These methods are also less likely to harm beneficial insects, like ladybugs, that might be present in your garden.
3. Onions treated with natural or organic methods are just as effective as those treated with chemical methods, and they're generally safer for you to consume.
4. Natural or organic methods of controlling onion maggots often rely on beneficial predators, like parasitic wasps, to do the job for you. These predators are generally harmless to people and pets.

In general, natural or organic methods are preferable for getting rid of onion maggots because they're safer for the environment and for you. If you're not sure which method to use, consult with an expert before proceeding.

Beneficial Nematodes

Onion maggots are the larvae of a fly that looks similar to a housefly. The fly will lay its eggs in the soil near an onion, and when the larvae hatch, they will burrow into the onion and start eating it from the inside. The onion will eventually rot and collapse.

To get rid of onion maggots, you can purchase beneficial nematodes from a garden center or online. You'll need to mix the nematodes with water according to the package directions, then pour them into a sprayer. Spray the mixture onto the affected area of your garden, being careful to wet the soil well. The nematodes will enter the larvae and kill them.

Neem Oil

Neem oil will kill onion maggots and other pests that may be bothering your onion plants. To use neem oil, mix two teaspoons of neem oil and one teaspoon of dish soap in one quart of water. This creates an emulsion that will help the neem oil stick to the plants and pests. Apply the mixture to the plants, being sure to coat the underside of the leaves where the pests are likely to be hiding. Reapply every few days as needed.

Insecticidal Soap

Insecticidal soaps are traditionally made from potassium salts of fatty acids. The soap is mixed with water and sprayed on plants. The potassium dissolves in the water and breaks down into two ions, K+ andfatty acid-. The fatty acid- ion is attracted to the cell wall of the insect and disrupts the cell membranes, causing the cells to leak and the insect to die.

If you have an onion that is infected with maggots, you can get rid of the little pests by using insecticidal soap. This soap is specially formulated to kill insects, and it will work on onion maggots as well. Just mix up a solution of the soap and water, and then spray it onto the onion. The maggots will drown in the soap and water solution, and then you can safely dispose of the onion.

Horticultural Oil

Insecticidal soap is a specially formulated soap that is designed to kill insects. It is made with ingredients that are safe for humans and animals, but that are deadly to insects. Insecticidal soap is an important tool in the fight against pests, and it can be used to protect your home, garden, and even your pets from harmful insects.

Horticultural oil is a great way to get rid of onion maggots. To use it, simply mix together equal parts horticultural oil and water in a spray bottle. Then, generously spray the mixture onto the affected areas of your onion plants. Be sure to coat the undersides of the leaves as well as the stems, as this is where the onion maggots are likely to be. Repeat this process every few days until the onion maggots are gone.
