Spider mites are among the most destructive pests in horticulture, damaging crops rapidly and thriving in hot, dry conditions. Their resistance to chemical pesticides makes biological control a critical and sustainable option. Predatory mites offer a powerful defense, ensuring healthier crops and more reliable yields.
Spider mite impact on crops
Tetranychus urticae (Two-spotted spider mite) is the most common species in greenhouse and open-field crops. These pests pierce plant cells, causing stippling, leaf yellowing, and eventual necrosis. Outbreaks can escalate quickly under warm, dry conditions - requiring proactive, effective strategies.
Biological control of spider mites with predatory mites


Certain predatory mites specialize in feeding on spider mites across multiple life stages, including eggs, larvae, and adults. Their integration into IPM programs forms the cornerstone of success, ensuring population suppression, crop vitality, and reduced chemical use.
Key benefits of using predatory mites
- Targeted action: feeding on all life stages of spider mites.
- No side effects: a natural solution without harm to other natural enemies or pollinators.
- No resistance development: unlike chemical pesticides, pests do not develop resistance to natural predators.
- No residue: supporting growers to meet residue requirements or organic certification standards.
- Compatibility: easily combined with other biological and soft chemical tools in an IPM program.
