A Beginner’s Guide to Using Eco Neem

So, you want to control pests on your plants, but don’t want to use harsh chemicals.

Eco neem is an eco-friendly alternative that can control pests without harming the environment.

Understanding how to properly use eco neem will help protect your plants and keep them healthy.

What is neem oil?

Neem oil is derived from the seed of the tropical neem tree (Azadirachta indica).

Neem oil works as a natural insecticide to help control both chewing and sucking insects including aphids, whitefly, scale, mealybugs and mites.

It reduces insect feeding, acts as a repellent, and interferes with insect hormone systems.

How does eco neem work?

Eco-neem is applied directly to the leaves of the affected plant, or it can be used as a soil drench.

When the insects feed, they consume the neem oil, which has the following effects on the pests:

  • Fails to shed their skin, which disrupts growth and reproduction
  • Loses desire to feed which results in starvation

You’ll be happy to know that eco-neem will kill only pests that bite, suck or chew on plants.

Beneficial insects (including bees) do not eat plants, so they will not eat the eco-neem.

What does eco neem treat?

Because eco-neem targets insects that eat the plant, it is effective against chewing insects and sucking insects.

Common insect pests controlled by eco neem include:

  • mites
  • caterpillar
  • mealybugs
  • curl grubs
  • citrus leafminer
  • fungus gnats
  • spider mites
  • aphids
  • whitefly
  • lawn armyworm
  • sooty mould

How do you mix eco-neem?

For applying directly to your plants, eco-neem should be mixed with water in a spray bottle.

The ratio will vary based on the pest you are trying to control.

For ornamental plants, most pests will be treated using a ratio of 10ml of eco-neam to 5 litres of water. Wingless grasshoppers and mealybugs require a higher amount of eco-neem.

For lawns and gardens:

  • use a ratio of 20ml per 5L to treat lawn armyworm, and
  • a ratio of 10ml per 1L to treat curl grubs.

Eco neem vs neem oil

Unlike other neem oil products, eco-neem is certified organic.

Eco-neem is made by a patented process that extracts the active properties from the neem seed without the inclusion of potentially harmful ingredients.

How to use eco neem for fungus gnats

Fungus gnat larvae live in the top few centimetres of soil. For this reason, eco neem is best used as a soil drench so that it can get to where the pests are.

Make a mix of neem oil using a ratio of 30mL per 10L water and pour this around the base of your affected plant. For best results, apply when larvae are present.

Repeat application may be required as the adult fungus gnats live for a number of days and may lay new eggs in the soil.

Pro Tip: Adult fungus gnats need to be able to access the soil in order to lay eggs. If you can create a barrier to the soil e.g. by covering it in sand or sphagnum moss, you will break the reproduction cycle.

How to use eco neem for curl grubs

Curl grubs are one of the most common lawn pests. They feed on the roots of grass causing dead patches on your lawn.

In severe cases, an entire segment of a lawn can die from a curl grub infestation.

Eco neem is an effective treatment for controlling curl grubs and other lawn pests.

It’s non-toxic to pets and can be used on lawns that have been recently mowed so you don’t need to wait until after cutting or watering in to apply it.

To use eco neem for curl grubs:

  • Make a mixture of 10ml eco neem per litre of water
  • Use a watering can to apply as a soil drench

The best time to use eco neem on curl grubs is when they are hatching, which is from mid Spring to mid Summer.

How to use eco neem for indoor plants

Eco neem is safe to use on all species of indoor plants.

Follow the recommended ratio on the container and make a mixture in a spray bottle to apply directly to your plants.

Is eco neem safe for vegetables?

Eco neem is only recommended for use on ornamental plants. It can be used to control chewing and sucking insects on roses and other flowers, as well as trees.

If you want to use something similar but more suitable for food crops, try Eco-oil. This product is safe to use on fruit and vegetables, and there’s no withholding period, so you can safely eat the same day that you spray.

  1. Hi, I have been a gardener for years and have recently moved into a flat so am gardening in pots – veges and ornamentals. My soil is inundated with small flies (fungus gnats?) I have eco neem. Can I drench the soil in pots? What about my veges – tomatoes, silverbeet and herbs? Thank you.

    • Are the flies black or white. If they are indeed fungus gnats, it’s best to let the top 5 cm or so of the soil to dry out before watering again as this will kill the larvae and make it less attractive to females to lay their eggs. I would also suggest getting some of that yellow sticky tape to hang around your plants. This will trap the adult flies and works equally as well for white flies.
