Common Cannabis Pests and How to Deal With Them Leave a comment

Beginning your adventure with growing marijuana plants at home may not be that easy a task, especially when it comes to fighting common cannabis pests. For the record, pests are like cops; the moment they put hands on our plants, you’re screwed – and that’s a beautiful yet sad metaphor, isn’t it?

Well, dealing with marijuana pests can become a pain in the neck – that we already know. But dealing with those insects is one thing, and preventing them from even appearing on your cannabis plant is another. Given this, before we elaborate on different ways to combat the unwelcome guests, let’s get to know these guys in the first place.

Most Common Marijuana Pests

The list of natural threats to your cannabis plant is quite long to be honest. However, we distinguish a couple of particularly persistent pests that can really go hard on your future harvest.

Aphids

Aphids are characterized by the pale yellow color and are known for being one of the most annoying pests a marijuana grower can ever confront. These insects reproduce like crazy, not to mention that they’re also easy to miss before they become a plague. Aphids typically feed on marijuana leaves by taking its nutrients away, which may ruin the entire harvest. Watch out for them, especially when growing weed indoors.

Spider Mites

Similar to aphids, spider mites have a rapid reproduction rate. Being the nightmare of rookie growers, spider mites can quickly wreak havoc to your crops, and thus discourage you from even thinking of growing cannabis again.These insects love humid places, so if you’re growing marijuana indoors, it’s of utmost importance to check for their presence on a regular basis.

When you see white, yellow, or black spots showing up on the leaves, it’s an indicator that spider mites have started spreading. The fact that they are sticky and extremely difficult to get rid of doesn’t make the situation better, too. Once you spot a spider mite, act as quickly as possible, because if you give them time to spread, they will kill your cannabis overnight.

Fungus Gnats

Although the latin name for these insects could suggest an exotic meal or some similar stuff, the reality is a far cry from your initial guess.

Also known as soil gnats, fungus gnats are about 4-5mm wide and they occupy both the lower areas of your plant and the soil’s surface. These insects are rather easy to spot; simply look for larvas with a dark head and transparent body. Fungus gnats can be typically found at the first few centimeters of your plant’s base because they like moist areas.

Despite being less destructive than spider mites and aphids, soil gnats can still cause serious damage to your crops – this applies to roots and stems, too. These insects aren’t picky, they just devour the plant entirely, starting from the base and finishing in the very root system. The moment you notice your plant is growing slower than before, look for these larvas and don’t neglect the danger.

How to Deal With Marijuana Pests Without Harming the Environment?

Being a marijuana grower leaves you with two paths to follow in order to get rid of the aforementioned cannabis pests: you can either become an organic grower and minimize the danger of pests without using artificial solutions, or you can draw out big guns and take the risk of consuming these chemicals with the smoke once your buds are cured, dried, and ready for use.

Needless to say, we want to contribute to our environment, and thus we’re going to focus on the organic pest control.

Integrated Pest Management (IPM)

The integrated pest management aims at remaining full control over pest population on your cannabis plant with nothing but organic solutions.

The IPM system involves a number of strategies any grower should apply to deal with marijuana pests and prevent their occurrence. You may very well use fragrant oils (peppermint and cinnamon are great) or foliar sprays to protect your crops against insects, but some people go even further by creating an ecosystem for the grow room with the so-called companion planting. Extra plants in the growing area serve as a strong shield against the unwelcome guests.

Other growers take their creativity to the entirely new level by purchasing predatory mites that control other pests. Keep in mind, though, that this method is not suitable for newbies, as it requires more in-depth knowledge about predatory mites and the way they interact with other insects.

Simpler Methods, Please?

Okay, I have good news for those of you who want to keep things simple. You can easily make a DIY organic pesticide by placing one teaspoon of cinnamon in a dish filled with one-quart water and mixing everything together. Then, you’re free to spray the substance on your plants to create a natural barrier against common marijuana pests.

On the other hand, if you aim at making a more advanced organic pesticide, add cinnamon tea or pure Castile oil to the initial mixture. You can use it interchangeably with a mixture of water and pressed garlic. Garlic comes with a plethora of benefits for our bodies, but you may very well use it on the cannabis plant. However, it’s best to keep the use in moderation; otherwise, it may kill the good insects as well.

Another natural ingredient that proves invaluable for dealing with common marijuana pest are cloves. Cloves are very effective in terms of the plant protection, so if you want to keep your crops clean and healthy, prepare a mixture of cloves and a couple drops of essential oils like citrus or peppermint.The aroma of cloves keeps aphids, spider mites, and ants away.

Last but not least, use your preferred mix to the new growth at the very beginning to protect you to prevent marijuana pests from appearing.
