How can you destroy spider mites? - briefly
Apply a miticide such as abamectin or spinosad, spray the plants with a vigorous jet of water or horticultural oil, and introduce predatory mites like Phytoseiulus persimilis. Maintain low humidity and remove heavily infested foliage to inhibit re‑infestation.
How can you destroy spider mites? - in detail
Spider mites thrive in hot, dry conditions and reproduce rapidly, so effective control requires a combination of immediate actions and long‑term strategies.

Cultural practices
-
Mechanical removal
-
Biological agents
- Introduce predatory mites such as Phytoseiulus persimilis or Neoseiulus californicus; these species consume large numbers of spider mites and establish self‑sustaining populations.
- Apply entomopathogenic fungi (e.g., Beauveria bassiana) that infect and kill mites upon contact.
-
Chemical options
- Select acaricides labeled for spider mite control, preferring products with low mammalian toxicity and short residual activity.
- Rotate active ingredients to prevent resistance; follow label rates and re‑entry intervals precisely.
- Use miticides only after confirming infestation levels exceed economic thresholds, to preserve beneficial organisms.
-
Preventive monitoring
Combining these tactics creates a robust management program that eliminates existing mite colonies, suppresses future outbreaks, and protects plant health with minimal environmental impact.
