The 10 Best Organic Insect Spray (Reviews 2023)

Top 10 Organic Insect Controls for Indoor

#1 Best Organic Neem Oil: Organic Verdana Cold Pressed Neem Oil – 16 Fluid Ounce

If you are serious about growing vibrant, healthy cannabis, then you will know Neem-oil is a must-have natural product to help prevent and cure insect and fungus problems impacting your crop. This Certified Organic Neem-oil from Verdana is totally non-toxic yet keeps away unwanted bugs without affecting friendly ones and keeps your plant looking beautifully green and bug-less without scaring away bees, butterflies or ladybugs.
With regular application of this powerful natural tonic, you will also help to suppress conditions that would otherwise thrive in the humid environment you will want to create for your plant. For example, this excellent product will prevent powdery mildew, rose black spots and rust fungi developing and stifling healthy growth. If used alongside sticky strips you can even bring an infestation of fungus gnats under control as the Neem makes the leaves inedible.
The only cons of this product is that it doesn’t like the cold, it can’t be used from 3 weeks before harvest and you need to apply it regularly to keep your plants bug free.

#2 Best Indoor Fly Trap: Sticky Bug, Gnat, and Fruit Fly Trap

When growing indoors it is easy to become overrun with all sorts of unwanted insects that your plants will hate and will ruin your harvest. These excellent insect catchers with double-sided glue work great to catch and trap fungus gnats, fruit flies, aphids and other flying pests without the need to spray your plant with harsh pesticides.
The pros of this product are that it is cheap (it comes with 25 strips), it is easy to install (comes complete with useful hanging hooks and a soil loosening tool), and it naturally removes pests (without the need for chemical use). However, once exposed, the strips do only last for around 30-days and putting them up can be a bit of a tricky and sticky process even with the usefully included tools. Ultimately, the best thing about this trap is that it will rapidly rid you of flying insect infestations.

#3 Best Azadirachtin for Cannabis Plants: General Hydroponics GH2045 AzaMax, 4 Ounce

Another excellent organic option for targeting whiteflies, spider mites, fungus gnats, thrips, aphids and leaf miners which attack your cannabis plants is through the use of Azadirachtin. Extracted from the neem seed kernel, this product from AzaMax works as an antifeedant and growth regulator – meaning that it prevents the synthesis and metabolism of the insect.
A real positive of this product is that there are no harsh chemicals involved so there will be no adverse effects on your plants. It is also incredibly smart and is able to target pests at different stages of their development, it is also very difficult for those pests to develop resistance to this product so you can continue to use it. This AzaMax Azadirachtin works best in warmer climates so one con of this product is that it won’t work as well for those of you living in colder climates.

#4 Best Pyrethrin Spray for Spider Mites: Bonide Products 857 Pyrethrin Spray Concentrate

If you are finding spider mites to be an issue or have tried Neem with little effect on a bug infestation, then you might want to give this Pyrethrin spray a try. Made from a chemical found in chrysanthemum flowers this chemical is also toxic to insects such as mosquitoes, fleas, flies, ants, and moths. This certified organic product is safe for use to keep your harvest insect free.
The pros of this product are that it is a highly effective insect killer that won’t damage your plant and even when ingested by humans can be rapidly broken down by the body. You can also gently rinse your plant with water to remove this product if you think it has been over applied. However, it can be more harmful to humans if it is absorbed by the lungs so you should be careful about using this product too close to harvest time, despite its organic status.

#5 Best Live Ladybugs – Small Bag: 150 Live Ladybugs – Good Bugs – Ladybugs – Guaranteed Live Delivery!

If you are growing indoors but like the sound of what ladybugs have to offer in terms of bug protection and wholehearted organic nature, then this small bag of live ladybugs might just be what you need. So whether you have an infestation of mites, moth-eggs, thrips, leaf-hoppers or whitefly, these will be the predator you need to take them out, whilst not being so many that your indoor grow space is more ladybug than weed paradise.
The best thing about this bag of ladybugs is that it is small, making it perfect for indoor growers, and will ensure you can keep your plants pesticide free even if you see the dreaded growth of a spider-mite population. The downside of using ladybugs indoors will be the added burden of looking after them – just make sure you release them into a contained space with plenty of water, food and an opening that will allow them to attend to the bugs you are keeping them to fight against.

#6 Best Organic Insect Control for Throughout the Growing Season: PyGanic Gardening 8oz

If you notice that the leaves of your cannabis plant have some small brown or black spots on them, or perhaps a trail that looks a little snail-like – then, unfortunately, some pesky thrips have decided to make your plants their home. These can be seriously damaging to your plants but, worry not, they can easily be eradicated thanks to this Pyrethrin Concentrate from PyGanic Gardening.
Pyrethrin is a natural insecticide that comes from Chrysanthemum flowers – so entirely natural. This extract is poisonous to insects as it shuts down their nervous system resulting in their death. This is a very popular natural alternative among cannabis growers. A real pro of this product is that it can be used at all stages of your plants’ growth – up until the harvest, a con, however, is that you really need to make sure you get your dosages right as it can damage your plant if you use too much concentrate.

#7 Best Predatory Mites: 2,000 Live Adult Predatory Mites

If you’re a committed organic grower but have found your plants overrun with spider-mites and had no luck getting the ladybugs to bring down their numbers, then a good alternative that has only recently become available commercially is the introduction of predatory mites to your garden. These bugs prey specifically on mites, making them highly effective if you are becoming overrun with broad mites, rust mites, cyclamen mites or russet mites.
The pros of this pest control option are their: 100% non-chemical nature with no risk of residual pesticide formation; targeting of mites specifically (including their eggs); suitability for hotter climates compared to ladybugs; and their huge appetite. However, as a new product to the market they are a lot more expensive than ladybugs and pesticides, but you won’t regret keeping pesticides off your plants and these guys are just as effective.

#8 Best Natural Mite Control Spray: Sierra Natural Science Mite Control – 1 Quart

If you are getting started with organic growing, have noticed that some of the certified organic pesticides still appear to be a harsh chemical product that you don’t want making its way into your crop, and don’t like the idea of adding more bugs into the mix, then Sierra Natural Science have a great range of products that will offer you a third way. This spray, made of natural salts and fatty acids drawn from rosemary kills mites and their eggs whilst being fully non toxic to humans and animals.
The best things about this product are that it is super effective at killing off spider mites and their eggs, it is not a harsh chemical that will leave nasty pesticide residue in your weed that could cause damage to your lungs, and it is a spray on treatment that doesn’t require more bugs to control a bug infestation! Whilst it is quite expensive, it definitely seems worth it considering the benefits you’ll get.

#9 Best Citrus Spray for Cannabis Plants: Bonide 218 Concentrate Citrus Spray, 32-Ounces

An organic alternative to using chemical based pesticides is citrus oil. Citrus oil can be used as an effective pesticide against common pests that congregate onto cannabis plants such as spider mites, aphids, and whiteflies. It is also a great option to use in combination with neem oil to make these organic pesticides more effective.
This product from The AMES Company comes in a concentrate so just add water and you can spray your plants immediately. Citrus oil is great to use as a preventative as well as a treatment for pests so it is worth investing in some of this stuff to keep your plants healthy and insect free.

#10 Best Natural Pesticide for Cannabis Plants: Sierra Natural Science Pesticide Concentrate

An attack of thrips, aphids, whiteflies or fungus gnats on your cannabis plants can be disastrous. Aphids suck out the important sap from your plants, thrips attack the leaves, whiteflies suck out the chlorophyll and fungus gnats damage the roots. You really need to target these beasts as soon as you spot them, and you can do this in a completely natural and organic way.
Step in Sierra Natural Science Pesticide Concentrate – as the name suggests it is made of completely natural ingredients, so no nasty chemicals. To set this to work add the correct amount of water and spray it directly onto your plants. It works by dehydrating the pests and also targets their food sources also (fungus and algae). To make destructive pests a thing of the past and watch your cannabis plants prosper, it is certainly worth investing in some of this stuff.

#11 Best Small Hand Sprayer: Solo 418 One-Hand Pressure Sprayer

If you are finding the need to regularly spray nutrients, pesticides and/or insecticides on your plants, then it is well worth investing in a decent sprayer. Compared with the other sprayer on this list, this unit is smaller, and designed for use with one hand only, which can be useful to help you reach plants tucked away in difficult to reach corners. Built with chemical resistant seals that can withstand the use of harsh chemicals, this unit will last a long time even under regular use.
Other pros of this product are: its adjustable nozzle that can be pointed in multiple directions; a locking trigger for if you have lots of spraying to get done; the useful pressure relief valve which doesn’t require you to fully unscrew the lid; and the effective anti-drip guard. On the negative side, the plastic material is not the sturdiest, so you do have to treat it with care to avoid creating cracks.
