This natural pesticide product contains Azadirachtin, a natural insecticidal ingredient found in Neem seeds.
Not only is it effective against caterpillars, but it’s also a thrifty and eco-friendly option for pest management in your garden.
In this article, we’ll explore how Neem Oil can help control and kill caterpillars on your oleander plants, as well as other tips and tricks for maintaining a healthy garden.
Will Neem Oil Kill Oleander Caterpillar?
The answer is yes, Neem Oil can effectively kill oleander caterpillars. These fuzzy critters can be a nuisance for oleander plants, but with the use of Neem Oil, you can get rid of them without harming your plants.
Neem Oil is available in natural pesticide products and concentrates that can be mixed with water to create a natural spray. When using Neem Oil to control caterpillars, it’s important to always read the label and follow the instructions carefully.
Neem Oil works by disrupting the insect’s hormonal balance, making it difficult for them to feed and reproduce. When applied correctly, Neem Oil can be quite effective against caterpillars as part of a comprehensive pest management plan.
However, it’s important to note that while Neem Oil is safe for most plants, it can be harmful to beneficial insects like bees and butterflies. Therefore, it’s important to use it sparingly and only when necessary.
Understanding The Oleander Caterpillar
The Oleander caterpillar is a bright orange caterpillar with black hairs that is commonly found in oleander plants. While they may seem harmless, they can quickly cause damage to your plants if left untreated. It’s important to note that even though the hair of Oleander caterpillars is not known to cause skin irritation in humans, it’s always better to be safe than sorry. When handling these critters, it’s recommended to wear protective gloves and avoid touching your face or eyes.
If you notice Oleander caterpillars on your plants, there are several ways to control and eliminate them. Handpicking them off the plants can be effective, but it can be a tedious task if you have a lot of plants. Another option is to use low toxicity and natural Bacillus thuringiensis-containing sprays marketed as Dipel, Thuricide and BT products. These sprays are slow to remove the caterpillars, but they stop feeding shortly after an application.
Synthetic sprays like Sevin and synthetic pyrethroids are also available for control, but it’s important to follow label instructions when using any pesticide. Seven Dust is another effective option for controlling caterpillars in oleander plants. It comes in either powder or liquid form, and it may take a couple of treatments, but you should be caterpillar-free in no time.
What Is Neem Oil?
Neem Oil is a natural pesticide that is derived from the seeds of the neem tree. It contains a natural insecticidal ingredient known as Azadirachtin, which is effective against a variety of pests, including caterpillars. Neem Oil is safe for humans and animals, and it doesn’t harm beneficial insects like lady beetles, ladybugs, birds, bees, butterflies, or earthworms.
Unlike conventional chemical and synthetic pesticides, Neem Oil targets specific insects or plant pests, killing them directly. It also acts as an organic fertilizer that helps make the plant healthier in general, increasing its resistance to various pest species. Neem Oil can be used throughout the growing season because it can kill pests at every stage of their life cycle, including when they are eggs, larvae (grubs), pupas, and adults.
When using Neem Oil to control caterpillars, it’s important to use it in the morning or evening and not in direct sunlight, as the combination of direct sunlight and Neem Oil can burn the plants. Additionally, it’s important to wash down plants immediately after spraying with Neem Oil if monarch caterpillars are present because they can be killed if they chomp on stems or leaves coated with Neem.
How Does Neem Oil Work Against Caterpillars?
Neem Oil contains a natural insecticidal ingredient known as Azadirachtin, which is toxic to insects and has been shown to affect caterpillars. The chemical works by blocking the insect’s nervous system, causing it to stop moving and eventually die. Neem Oil acts as a neurotoxin, which causes the caterpillar’s nerves to malfunction and ultimately kills it.
When using Neem Oil to control caterpillars, it’s important to dilute it with water and spray it directly onto the caterpillar’s body. The oil will quickly sink into its body cavity and kill it within hours. It’s also important to note that Neem Oil can kill bees, so it should only be sprayed at dusk when bees have returned to the hive.
Neem Oil is effective against many types of pests, including earwigs and aphids, so you don’t have to worry about killing your plants. Farmers have used Neem Oil to prevent caterpillars from eating their crops, and it worked so well that they would apply it to their fields before planting them to keep pests and other caterpillars away until harvest time.
How To Use Neem Oil On Oleander Plants
If you have an oleander plant that’s infested with caterpillars, using Neem Oil can be an effective solution. Here’s how you can use Neem Oil on your oleander plants:
1. Make your own Neem Oil mixture: You can buy Neem Oil in gardening stores, but making your own mixture is cheaper. You’ll need 100% Neem Oil (cold pressed and unfiltered), a spray bottle (500ml / 16oz), warm water, and dish soap. Fill the spray bottle with warm water and add 0.5 teaspoon of Neem Oil and a few drops of dish soap (3-4 drops). Put the lid on the bottle and shake it well.
2. Spray your plants: Once you’ve shaken the spray bottle, you can spray your plants. Make sure to cover every surface of the plant completely. It’s important to note that Neem Oil is an oil and doesn’t mix well with water, so you’ll need to shake the spray bottle every time before using it.
3. Repeat as necessary: Check your plants daily to see if the caterpillars have returned. If they have, repeat the spraying process until they’re gone.
It’s important to use Neem Oil sparingly and only when necessary, as it can harm beneficial insects like bees and butterflies. Also, it’s essential to read the label and follow the instructions carefully when using any pesticide product.
Other Natural Pest Control Methods For Your Garden
While Neem Oil is an effective natural pesticide, it’s always helpful to have a variety of pest control methods in your arsenal. Here are some other natural options to consider:
1. Diatomaceous Earth: Made from the fossilized remains of tiny aquatic organisms, diatomaceous earth is a fine powder that can be sprinkled around plants to control pests like aphids, snails, and slugs. It works by dehydrating the insects’ exoskeletons, leading to their demise.
2. Companion Planting: Certain plants have natural pest-repelling properties that can be used to your advantage. For example, planting marigolds around your garden can help deter pests like nematodes and whiteflies.
3. Homemade Insecticidal Soap: Mix together one tablespoon of mild dish soap with one quart of water to create a simple insecticidal soap spray. This can be used to control soft-bodied pests like aphids and spider mites.
4. Garlic Spray: Crush several cloves of garlic and steep them in a gallon of water for 24 hours. Strain the mixture and add a tablespoon of mild dish soap. This can be sprayed on plants to control a variety of pests.
5. Row Covers: Covering your plants with lightweight fabric or mesh can help prevent insect infestations by physically blocking them from accessing your plants.
By incorporating a variety of natural pest control methods into your gardening routine, you can keep your plants healthy and pest-free without relying on harmful chemicals.
Tips For Maintaining Healthy Oleander Plants
Oleander plants are known for their beauty and low maintenance, but they can attract caterpillars and other pests. Here are some tips for maintaining healthy oleander plants:
1. Regularly prune your oleander plants to keep them clean, tidy, and free from bugs. Pruning can also help control the bug population by instantly vaporizing them.
2. If you notice caterpillars on your oleander plants, apply Seven Dust onto the plants at the first sign of infestation. Seven Dust comes in either powder or liquid form and can be effective in controlling caterpillars.
3. Soak the soil around your oleander plants with organic neem oil pesticides to prevent pests and disease from taking hold. Repeat this process every 2 to 3 weeks until the insects have left the area or the disease symptoms lessen.
4. If you choose to use Neem Oil to control caterpillars, always read the label and follow the instructions carefully to avoid harming beneficial insects like bees and butterflies.
5. Dip the oleander leaves into soapy water to instantly kill aphids hiding in the leaf litter. Remove wilted, torn, or otherwise damaged leaves from the shrub to keep it healthy.
By following these tips, you can maintain healthy oleander plants and keep them free from pests and disease without harming beneficial insects.
