Look no further than neem oil!

This all-natural pesticide derived from the Indian Lilac evergreen’s seeds contains Azadirachtin, a potent substance that fights against a variety of garden pests, including sawflies.

In this article, we’ll explore the effectiveness of neem oil in controlling sawflies and provide tips on how to use it safely and effectively.

Say goodbye to unsightly damage caused by sawflies and hello to a healthy and thriving garden with neem oil.

Will Neem Oil Kill Sawflies?

The answer is yes, neem oil can kill sawflies. Sawflies are a type of pest that damage trees, shrubs, grasses, raspberries, and roses. They lay their eggs in slits cut into the foliage of plants, and once the larvae emerge, they begin to feed on the leaves, pollen, and/or buds causing unsightly damage.

Neem oil acts as a contact insecticide, which means that it kills insects upon contact. It contains Azadirachtin, which is a potent substance that works against a variety of garden pests, including sawflies. When neem oil is sprayed on sawflies, it disrupts their hormonal balance and prevents them from feeding and reproducing.

To use neem oil to control sawflies, mix 4 teaspoons of neem oil with a gallon of water and a little liquid soap. Spray this DIY sawfly killer on leaves and other affected areas. Reapply after heavy rains. Neem oil has a lasting effect because it’s sticky, especially when mixed with dish soap. You can mix water, neem oil, and dish soap and create a DIY home pest killer that lasts for weeks. The recipe is 1 liter of water, 12 drops of dish soap, and a few drops of neem oil depending on how concentrated it is.

It’s important to note that neem oil should be used with caution as it can harm beneficial insects like bees if not used properly. Always read the label and follow the instructions carefully. Avoid applying neem oil when pollinators or beneficial insects are present. Monitor adult sawfly populations with traps to allow for earlier detection of pest populations and suppress the number of new eggs being laid.

What Are Sawflies And How Do They Damage Plants?

Sawflies are a type of pest that belong to the order Hymenoptera. They are plant-specific and can damage trees, shrubs, grasses, raspberries, and roses. The female sawfly deposits her eggs in slits cut into the foliage of plants. Once the larvae emerge, they start to feed on the leaves, pollen, and/or buds causing unsightly damage.

Sawfly larvae look like large caterpillars with more than 5 pairs of legs and two eyes. They may be brightly marked with spots or stripes. Many of those that feed on conifers build webs or tents in which to feed. After feeding for three to four weeks, mature larvae spin a cocoon that turns brown and resembles a bud tip. Most fall to the ground. The adult sawfly will emerge from the pupal case, mate and start the life cycle again. Most sawflies have one generation a year; some have two.

When numerous, plant-feeding sawflies can cause substantial damage in forests and landscapes. Large trees are rarely seriously injured and normally put out another flush of leaves if heavily damaged. Young trees that are completely defoliated may be stunted or killed. Parasitic wasps and predaceous beetles commonly kill sawfly populations in natural habitats. In the landscape, larvae can be removed from trees and killed by squishing or dropping them into boiling water, although this is not practical on a large scale.

Small trees can be sprayed with a number of chemicals if mechanical removal is not effective. However, since sawflies may look like caterpillars or slugs but are not, it makes a difference in what chemicals are effective against them. For example, BT or Bacillus thuringiensis only works against true caterpillars and is ineffective on sawfly larvae – so be sure to read the label before using any insecticide.

Insecticidal soaps, neem oil, and many synthetic insecticides can be used to control sawflies. Apply insecticides only when larvae are actually present. It’s important to note that neem oil should be used with caution as it can harm beneficial insects like bees if not used properly. Always read the label and follow the instructions carefully.

Introduction To Neem Oil And Its Properties

Neem oil is a naturally occurring pesticide that is derived from the seeds of the neem tree. It has been used for centuries in traditional medicine and agriculture in India and other parts of Asia. Neem oil is known for its broad-spectrum insecticidal properties and is effective against over 200 species of insects, including sawflies.

One of the main active compounds in neem oil is Azadirachtin, which works by disrupting the hormonal balance of insects, preventing them from feeding and reproducing. Neem oil is also a hormone disruptor, which prevents normal growth and development in detrimental insects. It is effective in all stages of insect growth, killing eggs, larvae, nymphs, and adults alike.

Neem oil is considered safe to use as it is practically non-toxic to birds, mammals, bees, and plants. It is slightly toxic to fish and other aquatic organisms, but it does not harm beneficial insects like ladybugs and predatory mites. Neem oil does not impact honey bees and other pollinators like butterflies as long as they are not sprayed directly.

Neem oil can be used as a contact insecticide or as a systemic pesticide when applied to the soil. It has a lasting effect because it’s sticky, especially when mixed with dish soap. Neem oil can also be used to prevent pests from laying eggs on plants by stopping eggs from hatching and larvae from developing if sprayed directly on them.

How To Use Neem Oil To Control Sawflies

Neem oil is an effective and natural way to control sawflies on your plants. Here’s how to use it:

1. Mix 4 teaspoons of neem oil with a gallon of water and a little liquid soap.

2. Pour the mixture into a spray bottle.

3. Spray the mixture on the leaves and other affected areas of your plants.

4. Reapply after heavy rains.

It’s important to note that neem oil should be applied early in the morning or late in the evening to avoid harming beneficial insects like bees. Also, avoid applying neem oil when pollinators or beneficial insects are present.

Neem oil can also be mixed with dish soap and water to create a DIY home pest killer that lasts for weeks. The recipe is 1 liter of water, 12 drops of dish soap, and a few drops of neem oil depending on how concentrated it is.

By using neem oil, you can effectively control sawflies on your plants without harming beneficial insects or using harmful chemicals.

Precautions And Safety Measures When Using Neem Oil

While neem oil is generally safe to use, there are a few precautions and safety measures that you should keep in mind when using it to control sawflies.

Firstly, neem oil should only be used on soft-bodied insects, larvae, and eggs. It does not work on hard-bodied insects like beetles. So, if you’re dealing with a different type of pest, neem oil may not be effective.

Secondly, neem oil should not be ingested by pets or livestock as it can cause fatigue, diarrhea, and vomiting. Exercise caution when using neem oil around ponds, lakes, and other bodies of water as it can be harmful to fish, amphibians, and other aquatic organisms.

Lastly, neem oil is considered moderately harmful to bees, butterflies, and other beneficial bugs. To protect them, avoid spraying near known hives and only spray at dusk or in the very early morning before the pollinators are active.

Other Natural Remedies For Sawfly Control

Aside from neem oil, there are other natural remedies that you can use to control sawflies. One of these is diatomaceous earth (DE), which is made from fossils left in mineral deposits and is completely natural, so it’s safe for humans, pets, and plants. You can sprinkle DE on the soil of the plants you want to protect from the flies, as the larvae will be crawling around on it. Also, make a ring of DE around the stem to prevent any larvae from crawling back onto the plant after they’ve fallen off. This also helps stop them from migrating between plants as they’ve yet to fly. If they can’t climb up on the plant, this will save the leaves.

Another effective option is insecticidal soap, which is safe in the garden and will not harm your beneficial insects or other crops. It kills exposed sawfly larvae but may damage blossoms. If you find that treating with insecticidal soap is not having the desired level of effectiveness, we recommend trying neem oil next. Finally, if both of these methods still haven’t provided total relief, you may treat the affected plants with a Spinosad-based treatment, using caution around other crops and making sure to never use spinosad during the flowering phase of your plants.

In addition to these natural remedies, you can also prune damaged foliage and stems and introduce parasitic wasps and predaceous beetles to commonly kill sawfly populations. Diligent monitoring will allow for earlier detection of pest populations and will suppress the number of new eggs being laid. Remember to keep trying different methods, maybe add a few natural predators to your garden, and stay positive. These bugs may be tough, but we won’t let them bring us down!
