Onions are a popular vegetable that contribute to the flavor of many dishes. But these vegetables can also attract other creatures. Unfortunately, some animals love to eat onions too! If you grow onions in your garden, it’s important to understand what animals eat onions and how to protect them from getting eaten by unwanted critters. In this article, we’ll answer frequently asked questions about animals that eat onions in the garden, as well as provide useful tips on how to protect your onion harvest.
Thrips
Thrips are a type of tiny insect that can wreak havoc on your onion plants. They feed on the leaves, stems, and bulbs of the plant, leaving behind white streaks or specks.
Thrips can also transmit viruses that cause deformities in the onions. To protect your onions from thrips, remove any weeds around your garden and use insecticidal soap or neem oil to kill the pests.[1]
Onion Maggots
One of the most common animals that eat onions are onion maggots. These pests will ruin your onion harvest if left unchecked.
Cutworms
Cutworms are a type of caterpillar that can cause significant damage to your onion plants. They eat through the stem near the soil level, causing the plant to wilt and die. It’s important to keep an eye out for cutworm activity in your garden, as they can quickly decimate a crop of onions. Fortunately, there are some steps you can take to protect your onions from cutworms.
Chickens
One of the most common animals that eat onions are chickens. Not only do they enjoy the taste of this vegetable, but it’s also a great source of nutrients for them. Chickens especially love to peck at young and immature onions, which can cause damage to the plant. To protect your onion plants from chickens, you should consider building a fence around your garden to keep them away. Additionally, you should remove any fallen onions from the ground so that chickens won’t be tempted to eat them.[1]
Leafminers
Leafminers are small insects that feed on plants, including onions. They create tunnels or mines in the leaves and stems of the plant, which can weaken the plant and reduce its yield. Leafminers are hard to spot because they usually stay hidden inside the leaves. To protect your onion crop from leafminers, you should check your onions regularly for signs of infestation. If you find any, remove the affected plants and dispose of them far away from your garden.
Onion Flies
Onion flies are the most common pest of onions. They lay their eggs in the soil around your onion plants, and when their larvae hatch, they feed on the foliage and roots of your onion plants. Onion flies can cause significant damage to your onion crop if left unchecked. Fortunately, there are a few simple steps you can take to protect your onions from these pesky pests.[1]
Rats & Mice
Rats and mice are two common animals that love onions. They will seek out your onion patch and nibble away at them, leaving them with barely a trace of their original shape. Luckily, there are a few ways to protect your onion from rodent damage. First, you should be sure to keep the area around your onion patch tidy as rats and mice are attracted to clutter and debris. You can also use bait traps or sonic repellents to keep these animals away from your onions.
Snails and Slugs
Snails and slugs are some of the most common critters that will munch on onions in your garden. They often feed at night, so you won’t even notice their presence until it’s too late. If your onion plants look like they have been munched on during the day, then snails and slugs are likely to blame.
The best way to protect your onions from snails and slugs is to create a barrier around them. You can use copper tape or wire mesh to keep these pests away from your onion plants. Additionally, you can also set out beer traps or eggshells that have been crushed up in order to deter the snails and slugs from getting near your onions.[1]
Grasshoppers
Grasshoppers are a type of insect that feed on a variety of plants, including onions. They often jump from plant to plant in search of food and can quickly strip an onion patch bare if left unchecked. To keep grasshoppers away from your garden, try planting mint or tansy near the onions as these plants are known to repel grasshoppers. You can also consider using floating row covers to block grasshoppers from accessing your onions.[3]
Roundworms
Roundworms are attracted to onion beds because they provide an ideal habitat for them. The moist soil in an onion bed is the perfect place for roundworms to lay their eggs. Once hatched, these worms will feed on the onions, leaving behind unsightly holes in the bulbs and stalks. In order to prevent this from happening, you should regularly till your onion beds to disrupt the life cycle of these worms. You can also apply a light dusting of diatomaceous earth around the onions, which will help keep roundworms away.[3]
Owlet Moths
Owlet moths are among the most common animals that eat onions. These small, nocturnal moths feed on onion leaves and stems, causing significant damage to the plant. The larvae of owlet moth species such as the turnip moth (Agrotis segetum) and carrot rust fly (Psila rosae) are especially fond of onions.
To protect your onion crop from owlet moths, place floating row covers over the plants during the early stages of growth. This will prevent the adult moths from laying eggs on the leaves and stems. Additionally, you can spray insecticides containing Bacillus thuringiensis (BT) on the plants to stop larvae from feeding on them.
Deers
Deers are a common garden pest that will munch on your onions if given the chance. To keep deers away from your onion patch, it’s best to use physical barriers such as fencing, netting, or even thorny plants like roses around the perimeter of your garden. You can also install motion-sensing lights in and around your garden to deter these creatures from entering the area.
Birds
Birds such as ducks, geese, and chickens are all known to eat onions. Because of their sharp beaks, they can easily pick apart the onion leaves and consume the juicy bulbs. In order to protect your onion crop from birds, you can erect a fence or cover the area with bird netting. Alternatively, you can create a scarecrow-like object to deter the birds from eating your onions.
Moles and Voles
Moles and voles are two animals that can cause destruction to your garden, specifically when it comes to onions. They love digging through soil in search of their favorite treat – onions! Fortunately, there are a few ways you can deter moles and voles from eating your onions. First, make sure the area around your onion patch is free from rodents by regularly mowing the lawn and removing any debris that could provide cover.
Second, spread deterrents like crushed eggshells, strong-smelling soap, or cayenne pepper around the patch to discourage them from entering your area. Additionally, place hardware cloth or chicken wire around your garden bed as an extra defense against these critters.[3]
Groundhogs
Groundhogs, also known as woodchucks, are one of the most common animals that eat onions in gardens. These critters love to nibble on onions and can quickly decimate a crop if left unchecked. As groundhogs have sharp claws and burrow underground, they can often be difficult to keep out of your garden.[2]
Squirrels
Squirrels are one of the most common animals that will happily munch on onions.
Rabbits
Another common garden pest that loves to munch on onions is rabbits. Like squirrels, there are several methods for deterring rabbits from eating your onions. These include using repellents such as coyote urine, garlic or onion powder, or hot pepper spray. You can also build a fence around your plants to keep rabbits away.
Raccoons
Raccoons are notorious garden raiders and they love to eat onions. To keep them away from your onion plants, you can use motion activated sprinklers or lights that will scare them away when triggered. You can also build a fence around the plants using chicken wire or mesh, as raccoons are good climbers and jumpers so make sure the fence is tall enough.[2]
Dogs
Dogs may also be tempted to chow down on onions in the garden. To keep them away, make sure your garden is fenced off and that you don’t leave any onions lying around where your dog can get access to them. You should also pick up any onions that fall off of the plants as soon as possible so that they are not eaten by your pet.[2]
Cats
Cats love to explore gardens and may also get tempted by the onions.
To keep them away, you can use special repellents such as citrus peels or cayenne pepper, or create a barrier around the plants with chicken wire. You can also try using motion activated sprinklers to scare cats away if they wander into your garden.[2]
