In this article we want to talk about the insects that usually affect these marijuana plants.
Don’t be afraid if you find parasites in your marijuana plant. Nowadays there exist multiple solutions like Pheromone Traps against insects. These traps are really effective against plagues.
The Pheromone Traps for example, are chemical substances produced by the female insects, that are liberated in the air and attract male insects. Most of the sprays with pheromones try to avoid that the female insects copulate and the oviposition in the plants.
