Two-spotted Spider Mite Control

Defeat Two-spotted Spider Mites — Without Chemicals

Tetranychus urticae is one of the most destructive pests in commercial and home growing. Twospotted spider mites reproduce rapidly in warm, dry conditions — a single female can produce hundreds of eggs in her lifetime. Left unchecked, they cause stippling, bronzing, webbing, and complete defoliation. Biological control stops them at the source.

Signs of Twospotted Spider Mite Infestation

• Fine stippling or yellowing on upper leaf surfaces
• Webbing on undersides of leaves and between stems
• Bronzed, dried, or dropping leaves
• Visible mites (tiny, 8-legged, often with two dark spots) on leaf undersides

Biological Control Options

• Predatory mites (Phytoseiulus persimilis, Neoseiulus californicus, Amblyseius fallacis — hunt and consume spider mites directly; best deployed at first sign of infestation
• Generalist predators (lacewings, minute pirate bugs) — effective as part of a broader IPM program
• Bioinsecticides (insecticidal soaps, botanical oils) — for knockdown of heavy infestations before releasing predators

Why Biological Control Beats Miticides

• No resistance development — spider mites rapidly develop resistance to chemical miticides; predators stay effective
• No re-entry intervals — workers can re-enter treated areas immediately
• Safe for pollinators and other beneficials
• Works across all crops — cannabis, strawberries, tomatoes, cucumbers, ornamentals, and more
