Insecticide For Cannabis Plants

Insecticide for cannabis plants. An overwhelming majority of pesticides are geared towards outdoor pest control this site which you can buy can be used on cannabis plants. Synthetic pyrethroids (permethrin) and carbamates (carbaryl, carbofuran) was developed in the 1950s, and are quite safe for mammals, but capable of killing many insects. However, these insecticides are rarely used on plant crops.

Some insects are not desirable around our plants, while others we welcome with open arms. Many insects prey upon other pests insects. Ladybugs and lacewings are prime examples. To boost their populations, we buy and release beneficial insects in our garden. This is something I suggest for any type of garden and plant, not just for cannabis pest control.


Ladybugs are ferocious predators of aphids, spider mites, mealybugs, white flies, and other soft-bodied insects. Especially in their larval form. According to the Planet Natural Research Center, a ladybug will eat up to 50 aphids a day. That means that during its lifetime, a single ladybug is capable of consuming up to 5,000 aphids.

If you are struggling with soft-bodies pest insects, consider releasing ladybugs on your plants as organic cannabis pest control. Either for an outdoor grow, or in a greenhouse setting. I probably wouldn’t recommend this if you’re growing in your closet though. Ensure you’re buying native American ladybugs and not invasive Asian ladybeetles. Here is a trusted source for the right ones.

When you release your ladybugs, here are a few tips to ensure they stick around. They have a reputation for flying off.

  • When they arrive, store the ladybugs in the refrigerator until that evening. This slows down their metabolism and activity but is totally safe.
  • Release ladybugs that evening, just after the sun goes down.
  • Wet the plants that you are going to place them on first.
  • Ensure you release them near a food source, e.g. aphids.

Despite spraying our cannabis plants routinely with dilute neem oil (described below) we still find ladybugs all over our plants. This says a lot about just how mild neem can be. It helps deter pest insects but doesn’t impact the beneficial ones – when done right.

Green lacewings provide very similar benefits as ladybugs. They feed on aphids, leafhoppers, spider mites, mealybugs, thrips, and other soft-bodied insects. Most often, lacewings are sold and shipped as eggs, since they can be quite fragile. The benefit of this is that eggs can’t fly off upon arrival, as some ladybugs do. Here is one source to purchase lacewing eggs.

Like ladybugs, lacewings can be useful for cannabis pest control when released either outdoors OR in a greenhouse. We never used to see lacewings in our garden. Then, we bought a batch of lacewings eggs several years ago. Guess what? We see them all the time now.

Organic Cannabis Pest Control Foliar Spray Recipes

Before we dive into the details, it is important to note that these foliar sprays are divided into two sections – for a reason. For the most part, you want to avoid spraying your buds once they begin to develop, especially in organic gardening. Introducing extra unnecessary moisture can increase the risk of bud rot or mold.

More importantly, any ingredients, odors, or flavors in those sprays are going to be incorporated into the flower, which you then consume in one way or another. This alone is one of the largest motivators for us to grow our own cannabis at home. It is not uncommon to find pesticide and fungicide residue in the flowers from large-scale, inorganic, commercial cannabis operations that sell to dispensaries. I don’t know about you, but I don’t want to smoke that shit.

Therefore, we suggest using the neem-based cannabis pest control recipe below during the vegetative growth cycle only. We have found it necessary to use another foliar spray during the flower cycle, to ward off budworms (cabbage loopers). However, the ingredients in that spray are extremely mild, natural, and short-lived – and the only thing we personally feel comfortable treating our plants with once they’ve begun to flower. I’ll tell you more below.

Vegetative (Pre-Flower) Foliar Spray Recipe: A Neem-Based Spray

What is neem oil?

Neem oil is a plant-based concentrated oil, extracted from primarily the seeds of the India-native neem tree. Cold-pressed extractions yield the highest quality virgin neem oil and contain all the desirable active constituents.  In addition to being a natural, mild insecticide, neem also has healing medicinal properties and is commonly used in personal care products.

Neem oil is particularly effective against small soft-bodied insects. Examples include aphids, thrips, spider mites, mealybugs, and white flies – many of those so common to cannabis. However, it doesn’t seem to bother larger beneficial insects like ladybugs or bees – especially if you take care to spray it only in the evening hours when beneficial insects are least active.  Note that neem doesn’t do much to control caterpillars.

“Neem oil is made of many components, including Omega 3, 6, and 9 Fatty Acids. Azadirachtin is the most active component as a pesticide. It reduces insects’ ability to feed, and acts as a general insect repellent. It also interferes with insect hormone systems, making it harder for insects to grow and lay eggs. Azadirachtin can also repel and reduce the feeding of nematodes.”

Insecticide For Cannabis Plants

In the world of cannabis production, there are many ways to reach the end goal of growing a healthy, thriving crop. However, one thing that is clear is that insecticide is an integral part of the process. Insects can wreak havoc on your plants and their growth if left unchecked.

One way to combat this is by using an insecticide for cannabis plants. There are many different types available on the market today and each one has its own benefits and drawbacks. In order for you to make an informed decision about which product will be best for your needs, it is important that you know what these products do and how they work.

One example of an insecticide for cannabis plants comes in the form of a chemical known as neem oil. This substance is derived from seeds found inside a tropical tree called Azadirachta indica. The compound works by disrupting the nervous system in insects such as aphids, spider mites, and thrips which prevents them from feeding off your buds or leaves causing destruction or damage to them over time.

Can Neem Oil Be Used on Cannabis?

Yes. Neem oil is a safe and effective treatment for cannabis plants. Neem oil is made from the seeds of the neem tree, which grows in Southeast Asia. It’s most commonly used as an insecticide, but it can be used as a cosmetic, in food, and even on your pets.

Neem oil has been shown to be more effective than other pesticides at treating pests because it’s safer than many other chemicals. It also helps prevent diseases that cause insects to feed on the plant. In fact, neem oil can even be used to treat problems like powdery mildew and spider mites.

Neem oil is safe for use on both indoor and outdoor plants. It does not harm humans or animals, even when consumed, and it doesn’t leave any residue behind once you’ve applied it. You can use neem oil on other plants besides cannabis too; just make sure to avoid getting the leaves wet for three days after application so that the protective coating doesn’t wash off prematurely.

Can I Spray Insecticide During Flowering?

Yes, you can spray insecticide during flowering. Insecticides are a common way to prevent the spread of pests like insects and mites. However, if you are going to spray your plants with an insecticide, it’s best if you do so during flowering, not after.

When sprayed before flowering, insecticides will kill off any pests in your crop while they’re still small and manageable. If you wait until after flowering to spray, however, your plants will already be producing fruit or flowers and will have likely been exposed to many more pests than earlier on in their growth cycles. If you spray after this point, it might cause damage to your plants or reduce their fruit yields.
