The plants are infested by red mites or spider mites. Mites live on the undersides of plant leaves where many of them weave protective webs. We recommend the following:
- If you have other plants nearby, move the kit to another location (if possible) to avoid contagion
- Identify and remove infested leaves
- Sprinkle leaves with plenty of water
You can also try this homemade solution: Dissolve 1 teaspoon of soap shavings and put 5 drops of oil in half a liter of water and put in a spray bottle. The same amount of water and vinegar can also work. Spray the plant every 3 days.
