Cannabis, like any other crop, is susceptible to voracious animals looking for a field feast. Knowing your plant’s enemies is the first step in protecting them, whether you’re growing indoors or outside. This article discusses cannabis’ main predators, their tell-tale indications, and how to best eliminate them, from crickets to caterpillars, moles to mites.

Here we mention some of the most common Pests you could have on your Cannabis Plants:

First step: Prevention

Regardless of what kind of plants you aim to cultivate outdoors, you’ll need to take precautions; if you want the finest potential results, you’ll need to take it seriously. If you don’t take steps to prevent pest infestations, you may find yourself with a problem that you can’t solve.

When it comes to insect infestation prevention, you’ll need to do more than just use products. You’ll need to carefully organize your grow, employ high-quality products, and sanitize the area beforehand. Let’s take a look at what you should be doing right now.

  1. Plan your grow (space, quantity of plants, where, etc.)
  2. Use quality materials (substrate, flowerpots, stakes etc.)
  3. Use organic products (solid fertilizers, substrates, etc.)
  4. Disinfect the growing area and tools (flowerpots, scissors etc.)

These first few steps are just as crucial as the rest, and while they may not seem like much at the time, trust us when we tell you’ll be grateful in the long run.

Cannabis pests | Organic or chemical pest control?

It’s not difficult to see why organic products are superior to those made using chemical components. Chemical products may appear to be more effective at first, but they are not efficient. It’s impossible to predict how your plants will react, and it also degrades the quality of the soil you’re growing in. Insect infestations develop a natural tolerance to chemical treatments over time, and if you apply them incorrectly, you’ll wind up ingesting part of the substance when you eat whatever you’ve grown with them.

When you use organic preventive solutions on your plants, you’ll be providing them with a formidable defense system, as well as encouraging plant development and improving your plants’ natural defenses, all while enhancing soil quality.

When should you take steps to keep cannabis pests at bay?

Plant-protection products usually come with a set of instructions detailing how to use them, how much to use, and how long to use them for. Because most organic products don’t leave any chemical residue on your plants, you can theoretically ingest cannabis that has been treated with organic products without flushing. However, we do not advocate doing so because the flavor and consistency of the plucked buds may be affected.

To avoid this, we recommend avoiding using preventive products (even if they are organic) within 15-20 days of harvesting, regardless of the manufacturer’s instructions. Also, while your plant has bloomed, we don’t recommend using chemical treatments because it’s easy for the product to attach to the resin and stay on your plants indefinitely.

The optimal time to use anti-pesticides for cannabis is during the growing and pre-flowering stages. If at all feasible, do it first thing in the morning or shortly before the sun sets in the evening. Spraying after it has rained or before it is about to rain is likewise not recommended.

It’s also used to keep colds and flu at bay during the winter. Cannabis producers know it for its incredible antifungal and anti-insect capabilities, which are used to keep fungi and insects at bay.

Propolis is a propolis-based product that is sprayed on leaves, trunks, and branches every 15-20 days at a concentration of 2ml per liter of water. We recommend spraying it once a week if you want the greatest and most dramatic benefits. It also helps to repair damaged cells in your plants, making it ideal for sprinkling after pruning or topping.

It’s extremely good at getting rid of powdery fungus-like oidium and mildew, and it’s especially good at getting rid of grey mold like botrytis. We recommend applying this useful preventive product if you want your plants to thrive as well as possible.

We propose spraying your plants with propolis after cleaning and sealing the cuts for better results. This will ensure that no fungi or bacteria can come near that area.

Biological pest control

Biological pest control is a highly effective method of controlling cannabis pests; it is more effective at eliminating pests than at preventing them. Because they can only thrive if they have other insects to feed on, you’ll need to introduce new insects into your cannabis grow after the infestation has already begun. They’re not a good choice as a preventive measure.

If you have a lot of plants and can afford it, we recommend introducing fresh preventive insects into your grow every 20 days — it’s a terrific way to keep bugs at bay while also being environmentally conscious.

Everything’s simple for your insects to die out or not be able to battle pests effectively enough, so you’ll need to do your homework to ensure that it works properly.

You’ll need to keep an eye on the beneficial insects once you’ve placed them in your grow and be patient while they expand. The evil insects aren’t going to go away right away; it could take a while, so they could be fighting for days.

Obviously, unless the beneficial insects are capable of resisting the treatment, which is exceedingly unlikely, do not employ insecticides or preventive measures if you adopt this strategy.
