Treating Spider Mites in Harsh Conditions? This Predator Doesn’t Flinch.

If your grow is hot, dry, inconsistent—or all three—and spider mites or broad mites are settling in, Neoseiulus californicus is your biological first responder.

This mite is tough, fast, and flexible. It feeds across all pest stages, reproduces reliably, and stays active when other predators tap out.


Neoseiulus californicus Bottles

Treatment-Grade Suppression for Spider Mites, Broad Mites, Rust Mites, and More

Each bottle contains live adult mites only—no eggs, no juveniles, no waiting. As soon as you release them, they begin hunting eggs, larvae, and adult mites across a wide range of species.

If you’re already seeing pest activity, this is your go-to for fast suppression under real-world conditions.


Use This Product To Treat:

Pest Targeted Stages
Two-Spotted Spider Mites Eggs, larvae, nymphs, adults
Broad Mites All life stages
Rust Mites Best used in outdoor crops and ornamentals
Red & Flat Mites Good secondary suppression
Other Plant-Feeding Mites Flexible predator—feeds opportunistically


Californicus is one of the only mites that thrives in low humidity and high heat—making it ideal for tents, greenhouses, and field crops that don’t stay stable.


Why Use Bottled Adults?

Benefit What That Means
Immediate suppression No egg-to-adult lag time—adults feed on contact
Broad environmental range Survives in 50–105°F and 40–90% RH
Full lifecycle targeting Disrupts reproduction at every stage
Persists after cleanup Can survive on pollen, dust, and debris
Versatile application Use in tents, beds, greenhouses, or outdoor rows


This is your on-call mite killer when the weather isn’t cooperating and the pest list keeps growing.


How They Work

  • Females lay eggs near pest hotspots

  • Eggs hatch in 2–3 days

  • Juveniles feed + mature in 7–10 days

  • Adults feed and reproduce for up to 30 days

  • Pest suppression often visible in 2–5 days (depending on severity)

This isn’t passive prevention. It’s full-stage treatment with biological follow-through.


How Much to Use

Infestation Level Suggested Dose
Light 5–10 mites per sq. ft. (apply weekly)
Moderate to Heavy 25–50 mites per sq. ft.
Large-scale (preventive) 25,000–50,000 mites per acre


Reapply every 5–7 days during active infestations. For lasting suppression, follow up with Californicus sachets or compatible predators.
