Cannabis Pest Control, Alternative Methods...

Cannabis grown outdoors, though natural and vigorous, is at the mercy of natural elements. Pests, furthermore as strong winds and blistering daylight all, threaten to break to your plants if not taken under control. The value will occur over time, however, only too typically the injury is caused night long and might cause significant loss of foliage particularly to young plants. Pests are available several shapes and sizes, from principally visible caterpillars to teensy small aphids that area unit too tiny to identify. once these pests eat the plant’s leaves, it removes the plant’s ability to method light-weight from the sun into energy

Pests on cannabis, unfortunately, numerous different pests can overrun your planting area in as little as a couple of hours, however, thankfully there are also many ways of dealing with it. What will work best for your crop will be dependent on location, ethics, and budget?

The first two months or so are the most critical time for your plants’ development; meeting all her needs for a healthy, strong vegetative stage and ensuring that pests don’t take over. During the vegetative phase, any damage caused by insects or other pests can be quickly repaired by the plant’s natural response to heal itself.


Spiders and ladybugs are some of the beneficial predators that can be used to protect outdoor plants and keep pest numbers down. They are often bred specially for this purpose and purchased commercially. If you have a small cannabis garden, this may not be the most effective method of controlling pests, as the predators won’t have enough food to maintain them. These will work very well in a greenhouse or simple shaded enclosure.

Other than insects, predators such as frogs, turtles, and lizards are alternatives, if your growing near a river or stream. You can do this by merely leaving food for them near your grow site every once in a while. Birds are another predator that can be used similarly, encouraging them to visit with birdseed and bird feeders.


Due to today’s ‘organic movement,’ you can easily find both non-organic and organic insecticides. Organic insecticides work by copying the effects of a plant’s natural pesticides. A conventional organic insecticide used is pyrethrum, because of its superior strength.

Even though organic insecticides don’t contain chemicals, they still can kill beneficial insects and mammals as well including your predators that you have been using to keep the pests away! Use with caution and only if pests are destroying your outdoor cannabis plants.

When your cannabis plant begins to mature, the more efficient its own natural defences will be.


Another great option is homemade sprays and tonics to protect your young cannabis plants from harmful pests. You can find many recipes online, especially on homoeopathic gardening sites.

Here are a few recommended home remedies for cannabis pest control:

  • ONION AND GARLIC SPRAY - Garlic is well-known for its pungent aroma; it is this strong scent that comes into play when used as a natural insecticide.

    Mince two cloves of garlic with two medium-sized onions. Puree them in a blender or food processor with about a litre of water. Wait one hour and then add two teaspoons of cayenne pepper and one tablespoon of plant-based liquid soap to the mix, spray liberally on infested plants. This spray will keep its potency for up to one week if stored in the refrigerator.
  • CHILLI PEPPER / DIATOMACEOUS EARTH - Diatomaceous Earth is a natural substance and made from a sedimentary rock created by fossilised algae (diatoms). Diatomaceous earth has many uses in and around the home, and acting as a natural insecticide is just one of them. Diatomaceous Earth works not by poisoning or smothering the insects, but instead under its abrasive qualities and its affinity for absorbing the lipids (a waxy substance) from insects’ exoskeleton, which then dehydrates them to death. It will help control snails and slugs as well as other crawling insects.

    Grind two parts dry chillies with 1 part Diatomaceous earth, into a fine powder.
    Add to 2 litres of water and let sit overnight.
    Shake well before applying.
  • NEEM OIL - Neem oil is an extract taken from the seeds of the neem tree and is a potent natural insecticide, perhaps one of the most powerful, holding over 50 natural pesticides. This amazing oil is effective on insects at every stage of development, whether adult, larvae or egg. Neem oil acts as a secretion disruptor and as an “antifeedant” for insects that go after leaves and stems. It is biodegradable and non-toxic to pets, birds, fish, and other wildlife.

    To make your neem oil spray, add about 15 grams of high-quality organic Neem Oil and ½ teaspoon of a mild natural liquid soap to two litres of warm water.
    Stir slowly.
    Add to a spray bottle and spray on the affected cannabis plant foliage immediately.

    Neem oil can also be used preventatively by spraying the leaves of plants that are often ravaged by pests before an infestation takes place.

Apart from pesticides and insecticides, another great option would be to plant insect-repelling plants in and amongst your cannabis plants, for example, you could plant marigolds around your cannabis crop. The pungent smell of the marigold acts as a repellent to many insects are drawn to flowering plants.

Cannabis is vulnerable to insects and other pests; however, it's not recommended the use of pesticides on your cannabis plants. It is not environmentally safe, and you would not like to ingest or inhale any harmful chemicals. Pay particular attention to the substances with which you treat them, consider using only organic treatments on your marijuana plants, however, if you are going to use pesticides, be sure that you are using a product that is labelled “safe for use on food crops”.

Remember to use any kind of pesticide, organic or not, as little as possible.
