How Do You Get Rid of Spider Mites—Fast?
If there’s webbing in your canopy, you’re past prevention.
It’s time for something that hunts spider mites now, not next week.
Phytoseiulus persimilis is your go-to specialist for full-blown infestations. These red-orange predatory mites don’t just suppress—they wipe out spider mites at all life stages: eggs, larvae, and adults.
They don’t stop to scout. They dive straight into the webbing and get to work.
Phytoseiulus persimilis Bottles (Live Adults)
Targeted Knockdown for Spider Mite Infestations
Each bottle contains fast-moving adult mites—no eggs, no juveniles, no waiting. As soon as they’re released, they begin feeding and reproducing directly inside mite colonies.
This is a direct-response tool for:
-
Two-Spotted Spider Mites (Tetranychus urticae)
-
Carmine Red Mites
-
Pacific Mites
Best For
-
Visible webbing and active spider mite damage
-
Infestations that have outpaced prevention
-
Warm, humid setups (tents, greenhouses, gardens, and field crops)
-
Growers who want results in under a week
Why Bottles?
| Feature | Why It Matters |
|---|---|
| Immediate action | Adults begin feeding on contact |
| Fast lifecycle | Full development in just 7 days |
| Web navigation | Excels in dense mite webbing |
| Scalable | Works for single-plant outbreaks or large-scale treatment |
| No sprays needed | Safe for organic and zero-residue systems |
This is your emergency-response predator—not a slow-release insurance policy.
How They Work
-
Adults begin feeding immediately
-
Females lay eggs near spider mite clusters
-
Eggs hatch in 2–3 days
-
New predators mature in ~7 days
-
Adults live for 20–30 days, continuing suppression as new waves hatch
Visible reduction in spider mite activity can occur in 2–5 days under good conditions.
Application Rates
| Use Case | Suggested Rate |
|---|---|
| General infestations | 0.5–2 mites per square foot, weekly as needed |
| Heavy infestations | 500–25,000+ mites depending on pest pressure |
| Spot treatments | Focus releases directly on infested areas |
Apply in the early morning or evening for best results.
Avoid direct watering or overhead misting immediately after release.
Environmental Guidelines
-
Temperature: Best at 68–90°F
-
Humidity: Needs 60%+ for strong reproduction
-
Not cold-tolerant: Avoid if space is under 60°F
-
Dry setups? Pair with Neoseiulus californicus for broader climate flexibility
Safe for Everything But Spider Mites

Pro Tips
-
Deploy as soon as webbing appears—earlier is always better

Don’t spray before or after—residues will kill your persimilis
-
Maintain humidity and avoid aggressive airflow
-
For lasting control, follow up with slow-release sachets or californicus for broader coverage
-
For stacked control, combine with Swirskii if other pests are present

FAQ
How does the Live Guarantee work?
We know how important it is for your mites to arrive healthy and ready to work. That’s why we offer a live arrival guarantee—with flexible options depending on when we hear from you:
- Let us know within 24 hours of delivery: We’ll gladly send a free replacement shipment.
- Let us know within 2–3 days of delivery: We can offer store credit to make things right.
- After 3 days from delivery: Because these are living organisms, we’re not able to offer replacements or credit beyond that window. By then, it’s harder to know what went wrong or whether shipping conditions were a factor.
We truly want your mites to succeed—so please open your package as soon as it arrives and check on them. If something doesn’t look right, don’t wait—reach out and we’ll take care of you.
Where are you located?
We have a number of different locations in NJ, Maine and Oregon. While we'd love to have you, we are not currently open to the public.
Can I call you?
We get it. Sometimes it's easier to talk to someone, and on a case by case basis we can try to figure it out. Unfortunately though, we're really not able to take calls—FGMN is a small nursery, and we're usually elbows-deep in plants or packing boxes. To make sure nothing gets missed (and everyone gets a timely reply), we keep all communication in writing.
Feel free to message us at info@fgmnnursery.com. We mostly respond quickly, but every once in awhile replies may take a day. Do follow-up if you don't hear in that time. We're human, we miss an email here or there.
Too Many Options?
We get it. Try our mite/insect matchmaking quiz and instantly get matched to the solutions you may need.
Our Live Delivery Guarantee
We stand behind every leaf and every mite. If your plant or predatory insects don’t arrive alive on the first delivery attempt, we’ll make it right.
Here’s what you need to know:
- Email us at info@fgmnnursery.com within 24 hours of delivery
- Include clear photos of the item and the shipping label
- Someone must be available to receive the package—plants and bugs don’t do well sitting in the sun, a mailbox, or the back of a delivery truck
For plants, we offer store credit if something goes wrong.
For predatory mites and beneficial insects, you’ll have the choice of a replacement shipment or store credit.
If you contact us after the 24-hour window, we may still be able to help—just know it’s handled case by case.
We pack with care, insulate when needed, and check the weather before shipping. But once it’s in transit, the fastest way to protect your order is to open it right away.

The Hidden Weather That Shapes Plant and Predator Life
Invisible weather shapes every growing space. Warm air pools under lights, cool air settles near the floor, and in between, tiny predators decide where they’ll thrive. Learn how microclimates influence the balance between plants, pests, and the mites that keep them in check.
If Ladybugs Are Just Going to Fly Away, Why Use Them?
Most ladybugs don’t fly off out of spite — they leave when the environment isn’t right. Learn how temperature, humidity, and shelter affect whether they settle or scatter, and how to create the ideal setup that keeps them working where you need them most.
