I put together a list of cannabis pests and relatively safe treatment products.

Disclaimer: While almost all of these are certified organic and are relatively safe, even organics can pose a threat to humans, animals and the environment. Do some research if you plan to use these (some beneficial predators may also be harmed by some of the products). In the same respect, this list is not exhaustive, nor is it being shared as fully vetted. Do some research. There may be products that work for some of these I haven’t listed or there may be pests that some products treat that I did not include. Do some research. Use caution when using these as time of application, combinations with other products, or number/timing of treatments may pose hazards to you, your plants, or the environment.

Where specific pests are identified, the sources used were specific, but where they are general, the sources did not go into detail (i.e. spider mites vs. mites). Where the term “soaps” or “oils” are used, they are general terms meaning insecticidal or potassium soaps and vegetable and/or essential oils respectively.

Many of these pests may be treated best through alternating products and applications. Do some research. This is just a starting point to head us in the right direction. I used many different sources, but made sure each had some level of credibility. If I don’t get too many haters, I may do the same for non-insect cannabis plant pathogens.
