Do you smell that? It’s garlic! It’s eggs! No—it’s neem oil! This oil isn’t known for its flowery smell, but it is an extremely effective, all-natural pesticide and medicinal plant oil.
In fact, it’s often found in the secret stash of most gardeners worth their salt in caring for plants.
This pungent, thick oil made from the seed of the neem tree has been used for thousands of years in homeopathic medicine, but Westerners mostly know neem as an amazing pest-repellent (when used properly).
The thing is, indoor gardeners are commonly frustrated by this alternative to chemical pesticides: Even if you’re not buying neem oil concentrate, you almost always need to mix neem oil with water and mild soap before applying it to your plants in order to emulsify the fatty acids and prevent leaf burn.
Yes, you can burn your plants by using neem oil for plants incorrectly, so be sure to read up before applying a soil drench or dousing young foliage in this pesticide.
When used effectively, however, neem oil repels common houseplant pests like aphids, mealy bugs, fungus gnats, and spider mites kill larvae in the soil, and can be used to make your plant’s leaves shine like spring just arrived—every day of the week.
In this guide, we’ve reviewed the best neem oils for a wide variety of gardening needs, plus one for use in your skincare routine 😌 When looking for the best neem oil for plants, it’s important to consider how much you’ll need and what the dosing instructions are since neem oil does expire (see our FAQs for details). This is what we recommend:
The best neem oil for plants
1. Best overall neem oil: Verdana Organic Cold Pressed Neem Oil (8oz)
key specs: available in 8 oz, 16 oz and 32 oz | USDA Organic, cold-pressed, un-refined, filtered neem oil | mix with water and mild soap before use
This cold-pressed, pure neem oil from Verdana is our top pick for versatile pest treatment. It comes in four convenient sizes to suit everyone from the apartment houseplant fanatics to the greenhouse gardener looking for an effective, all-nature insecticide. With nothing added and nothing removed, expect a richly-scented dark brown liquid that looks like toasted sesame oil and smells like garlic. It’s earned Amazon’s Climate Friendly Pledge recognition for its USDA Organic certification. Not that this producer is currently listed in the USDA Organic Integrity Database after updating its practices and certifications. Shake it well before mixing with a mild soap (we recommend castile soap) and water!
- Has earned Amazon’s Climate Pledge Friendly
- USDA Organic certification
- Safe for pets and people
- Quality sealed—no mess in shipping like other neem oil brands
- Non-GMO Project certified
- You need to mix this neem oil with water and soap before applying to your plants—but it’s totally worth the extra effort!
2. Best budget neem oil: 100% Cold Pressed Neem Oil from the Neem Oil Company
key specs: available in 8 oz or 32 ox | cold-pressed and OMRI Listed for Organic Use | mix 2 Tbsp neem oil with 2 Tsp mild soap per 1 gallon of warm water
Looking for a budget-friendly solution to pest control? You’ll love this cold-pressed, 100% pure neem oil from the Neem Company. The instructions for use are clearly illustrated and written on the bottle (as with most neem products in this guide, you MUST mix this with water and mild soap before use), and the packaging is cute!Please note that there is conflicting research about the safety of 100% neem oil for pollinators (see the bottom of this guide for more details), and this product’s claim that it is “safe for pollinators and beneficial insects” isn’t the whole story. Due to its slightly thinner consistency than most neem oil products and nutty smell (more like peanuts than garlic), we suspect this neem oil has been refined but can’t find additional information about its processing. Buy 8 ounces if you only have a few houseplants, or 32 ounces for larger indoor and outdoor gardens. It works well as a leaf shine for monstera, pothos and other broad-leaved indoor plants.
- Thorough instructions for blending neem oil, water and soap in the correct ratios are right on the bottle
- Affordable and easy to use
- OMRI listed for organic use
- Sourced from small farms
- You’ll need to buy mild soap and a spray bottle separately
- Origin is unlisted and we suspect it’s refined, but no information is available on the processing
3. Best concentrated neem oil: Bonide Neem Oil Concentrate
key specs: 16 oz bottle | 70% neem oil extract and 30% stabilizers | mix 2-4 Tablespoons per gallon of water
If you’re looking for the all-around best organic fertilizer for your indoor garden, this pick from This highly concentrated neem oil extract from Bonide is an efficient, easy-to-store solution to your pesky pest problems. It contains 70% clarified hydrophobic neem oil, the active pest-control ingredient, which requires stabilizers to make an effective pesticide. That’s what you’ll find in the other 30% of this product. Produced by the US-based, family-started business Bonide, this company has nearly 100 years of experience making pesticides and insecticides for home gardeners. The big downside to this neem oil product is that it’s toxic to bees, so don’t use it when pollinators are out and about in your garden! It can also irritate the skin and eyes in concentrated form, so it’s probably best for gardeners without pets or kids. Take the advisory “for organic gardening” with a grain of salt; this product isn’t OMRI approved.
- 3 uses in 1 product; insecticide, miticide, and fungicide
- Stops powdery mildew in 24 hours, controls blackspot, rust, spider mites, and other common household pests
- Concentrated 70% neem solution is easy to store and lasts longer than 100% neem oil products
- Safe for use up to the day of harvest for vegetables and herbs
- Toxic to bees exposed to direct treatment
- Causes eye and skin irritation on contact in concentrated form
- Not really sure what’s in the 30% of this product that’s not neem extract!
4. Best ready-to-use neem oil: Bonide Neem Oil: Fungicide, Miticide, and Insecticide
key specs: 2 pack of 32 oz bottles | 1% clarified neem extract and 99% other ingredients | spray directly onto plants
Not all neem oil treatments require mixing and dilution. This RTU (ready to use) neem oil spray from Bonide is our recommended conventional alternative to pure neem oil or neem oil concentrate, but purists should note: It’s less than 1% neem oil extract! Although it advertises protection against fungus, mites, and insects at all life stages, this product is most effective against mature fungus gnats and aphids. It’s not the best neem oil product for killing larvae and is toxic to pollinators directly after application, so use with limited expectations. It’s handy in a pinch, but we think you (and your plants!) will be happier with the results if you take time to mix your own solution.
- Highly effective against fungus gnats and aphids
- Longer shelf life than pure neem oil products
- Spray directly onto plants, including roses, flowers, ornamental plants, veggies, herbs, fruit trees, and houseplants for a quick and easy pest treatment
- Can be used up to the day of harvesting herbs, fruits and veggies
- Not certified for organic gardening
- Toxic to pollinators directly after application

6. Best bulk neem oil: Neem Bliss Pure Organic Neem Oil
key specs: 1 gallon container | USDA Organic unrefined, filtered neem oil | mix 1 1/2 Tsp neem oil plus 1/2 Tsp soap with 1 quart water to use
If you want to stay away from concentrated neem products but need a LOT of this natural insecticide for your plants, this pure, premium neem oil from Neem Bliss is your go-to. When mixed into an insecticidal soap, it’s just as effective at combating spider mites, mealy bugs, aphids, fungus, and gnats as any neem oil in this guide. It comes in a range of quantities all the way up to a full gallon that should suit most bulk buyers.
Note that due to the high fatty-acid content of this neem oil, it solidifies at temperatures below 60°F or so. This feature may complicate storage if you’re planning to pop this in the fridge to extend its shelf-life, so it’s best for gardeners who will use it within 6 months.
- OMRI Certified for organic growing
- Quality sealed for no-worries shipping
- This is a LOT of neem oil! Enough to treat all of your indoor plants, your greenhouse, and lawn—with leftovers to share with neighbors
- This product is stronger-smelling and a bit thicker than other neem oils due to its processing; expect a coconut-oil type consistency that definitely doesn’t smell like roses 😉
- Storage may be tricky due to its consistency and expiration
7. Best neem oil for skincare: Vegan Mia Clarity No. 15 Concentrated Balancing Elixir
key specs: .34 Fl Oz | blend of 7 nutrient-rich oils | add 3-5 drops to your face moisturizer morning and night
Neem oil has been used for thousands of years in Ayurvedic medicine, the ancient Indian healthcare practice, to treat skin and hair conditions and make skin glow all over. If you’re not wild about the idea of using a strongly garlic-scented oil on your face, though, this Balancing Elixir from Vegan Mia is a good solution.
It’s a blend of sunflower seed oil infused with neem leaf extract, amongst other medicinal plants and herbs, jojoba, rosehip seed, passionfruit seed, black cumin seed, along with bergamot, cypress, vetiver, ylang ylang, coconut and vanilla for a heavenly, herbal scent.

FAQ About Using Neem Oil for Plants
Q. Is neem oil safe for bees?
The best answer to this question is, no neem oil is not bee-friendly. Scientific research by the University of California has shown that when used outdoors, neem oil is moderately toxic to bees for the same reason it keeps other pests away: It disrupts their reproductive cycle. Using neem oil indoors generally presents low risk to pollinators (unless you’re beekeeping 🐝 in your living room!!), which makes it suitable for houseplants. UC recommends application only during late evening, night, or early morning and when plants are not blooming, i.e., when bees are not typically out foraging. Bee Culture magazine has great recommendations for pollinator-friendly pest control if you’re keen on non-toxic alternatives for outdoor use. Although neem oil is considered non-toxic to people and other mammals, do take precautions with this potent product if you have sensitive skin. You can read more about common reactions and precautions in the National Pesticide Information Center.
Q. Does neem oil expire?
Yes! Every neem product should come with an expiration date on the bottle—usually neem oil expires about 12-18 months after the date of purchase. Cold-pressed oils last longer and retain their potency longer than hot-pressed oils, so choose these whenever possible. To increase the shelf-life of your neem oil, store it in a cool, dark place. The fridge is a good option if you don’t mind warming up the neem oil in a water bath before use, because it will solidify at temperatures below 60° F or so.

Can the Neem products be used around cats.
Yes, neem products are generally safe to be used around both cats and dogs.
Just to be sure, I double checked for you and found a statement by an ASPCA staffer: “Neem oil is not listed as a toxic plant product for cats or dogs as per the ASPCA Poison Control Center or Pet Poison Helpline.”
I hope that helps.
