Three-Stage Biological Kit for Thrips Control
Amblyseius swirskii · Orius insidiosus · Steinernema feltiae
5.0 · 1 reviewsA three-part kit for an established thrips problem: Amblyseius swirskii predatory mites for the larvae on the leaves, Orius insidiosus pirate bugs for the adults in the flowers, and Steinernema feltiae nematodes for the pupae in the soil. All three go out the same day, released onto the plants and drenched into moist soil. It is sized for moderate pressure, and it does not suit Echinothrips, which pupates on the leaf rather than in the soil.

Conditions for releasing thrips total control - three stage system
Thrips total control - three stage system work best when the growing space stays 65–85°F, 60–75% RH. These are preferred conditions, not hard limits.
Best temperature65–85°F
The band where all three agents are at peak activity at the same time, which is the point of running them together.
Best humidity60–75% RH
Critical rather than preferred, because of the nematodes: bone-dry media kills them. Keep the substrate consistently moist — not waterlogged — for two weeks after the drench.
RefrigerateNematodes only
Only the nematodes want the fridge, and they want it immediately. The mites and the Orius do not — they go out the day the box lands. Daylength matters for Orius too: under short days they go dormant, so fourteen hours or more keeps them hunting.
Releasing
What to do, and what you'll see
What to expect
- The Orius will be moving. Open their container and you'll see small, dark bugs bustling in the hulls. Normal, and a little startling the first time.
- Then the Orius vanish into flowers. After the first few hours they settle into buds and blooms where adult thrips hide. Out of sight means out working.
- The other two stay hidden. The mites look like pale grains and the nematodes are invisible in the soil. That's exactly how they're supposed to look.
- Fewer thrips, cleaner leaves. Over two to three weeks, fewer adults land on your cards and new growth comes in clean. Old scars stay as they were.
How to release thrips total control - three stage system
You may need to retreat
Eggs and young pests you can't see yet keep hatching after the first release. A second round catches that next wave.
You're done when you're seeing fewer pests and new growth comes in clean. Still seeing them, or fresh damage on new growth, at the check? That's your cue for another round.
Put it on a schedule and the next kit arrives on its own, 10% off the first and 15% off every one after. If it turns out you don't need it, pause or cancel anytime from your account.

For the curious
Everything else we know about them. Tap a topic to open it.
Is this your pest?
Thrips occupy three places at once: larvae on the foliage, adults in the canopy and the flowers, pupae in the soil. Total Control is the kit that covers all three, so no stage is left running to refill the others.
Thrips rasp the leaf surface and drink what comes out, leaving silvery or bronzed scarring with black frass specks on it, worst on the newest tissue and inside folded growth. Flowers come out streaked and distorted. The adults are slim and quick and fly up when you disturb a plant.
Three agents, one for each place thrips live. Amblyseius swirskii works the foliage and takes the larvae. Orius insidiosus, the minute pirate bug, hunts the adults in the canopy and in the flowers — the flying, feeding, egg-laying stage no predatory mite can catch. Steinernema feltiae nematodes take the pupae in the substrate. Nothing gets left running.
Then: is Total Control the right answer to it?
Choose this if
Choose it at moderate thrips pressure when you want the whole cycle broken rather than one stage suppressed. Covering all three stages at once is what makes that possible — partial treatments look like they are working and then are not, because whichever stage you missed refills the other two. It is also remarkably little work for what it does: all three go out the same day, in any order, with no waiting period between the foliage predators and the soil drench. Nothing to spray, no residue on the leaves, no re-entry interval and nothing to keep children or pets out of the room for. Between them these three reach the leaf undersides, the flowers and the root zone — more of the plant than any spray program covers — and thrips cannot develop resistance to being eaten.
Choose something else if
If there are no adults in play, Thrips Rapid Response covers the other two stages for less. If the infestation is genuinely runaway — widespread damage, high numbers in both soil and canopy — Ultimate Control upgrades the foliage mite and swaps the soil agent for one built for that. And if what you have is Echinothrips, dark and sluggish and on the leaf blade rather than in the flowers, it pupates on the leaf rather than in the soil, so the nematode third has nothing to find.
What it kills, and what it won't
Orius is the piece that makes this a complete answer rather than a good one. It is one of very few predators able to take an adult thrips at all — everything else in biological thrips control works on the stages behind them. That is the difference between a population that keeps topping itself up and one that runs out.
How it works
What it does to the pest, what it does on the plant, and what that leaves you looking at.
Three places, one day
Swirskii onto the foliage for the larvae, Orius into the flowers for the adults, Sf nematodes into the substrate for the pupae. They are compatible and the sequencing does not matter — there is no waiting period between the foliage predators and the soil drench. The gaps are what hurt you, not the order.
Orius hunts where thrips actually are
Adult thrips concentrate in flowers and buds, and so does Orius — it eats pollen as well as prey, which is what keeps it in the right place between meals. It is also the one agent here big enough to notice: small, fast and dark.
You read it on the cards and the crown
Blue sticky card counts fall as Orius works the adults, and new growth opens clean as the mites hold the larvae. Existing silver scarring never goes away — it is a record, not a reading — so judge it on new tissue and on the trend, not on the leaves you already have.
Being straight about one interaction. Orius eats predatory mites as well as thrips, and has been shown to push them out of flowers. The mites here ship loose, so spread them thinly across the foliage rather than leaving the carrier in piles, and expect to lose some to the bugs. It is not a reason to drop an agent: on its own, each one leaves a life stage running.
About the Total Control kit
Three separate products in one box, because thrips use three habitats. A mite bottle, a container of live Orius and a nematode pack — all released the same day.
New to beneficials?
Five things that catch almost everyone the first time.
What arrives
Three separate products: a bottle of loose swirskii in carrier, a container of live Orius in buckwheat hulls, and a pack of live Sf nematodes.
Only the nematodes want the fridge. The Orius will be moving when you open them, which is normal and mildly startling the first time.
All three the same day. They are compatible and the order does not matter. What does matter is not leaving a stage untreated while you wait for a better moment.
When it ships, and when it lands
Shipping
We ship when they're ready to travel. Live orders go out Monday to Thursday. If a colony needs a beat to peak, or we're propagating a fresh batch, yours might hold up to a week. All mites and insects ship 2-day or Overnight depending on what's best for them.
When it lands
Open it the day it lands. Sticky cards down first. Sprinkle the swirskii thinly across the canopy — thinly matters here, because piles of carrier are where Orius finds them. Release the Orius into and around the flowers and buds, at dusk if you can. Then mix the nematodes with room-temperature dechlorinated water and drench every pot, already moist, watering again afterwards to carry them to the root zone.
Why we pack extra
Two days in a van is a long trip for something this small, so we send more than you paid for.
A predatory mite is the size of a grain of table salt and an Orius is not much bigger. They ship in bottles, in a van, for two days.
A trip like that is hard on anything this small, so we price it in: the number on the label gets counted out, and then roughly 15% more goes in on top as a cushion.
Your 200-Orius container leaves here holding more than 200, and the mite bottle the same. The cushion is on us.
If you can see them
Ladybugs, lacewing larvae, Orius — the minute pirate bug — and the beetles. These are the ones big enough to see in the container.
Cold insects are very good at sitting still. That's normal. Release them as this page says, and watch the pest instead.

If you can't see them
Mites, nematodes, eggs — two thirds of this box. A bottle of carrier looks the same whether it holds live mites or none, and a nematode pack tells you nothing at all from the outside.
Email info@fgmnnursery.com and our entomologist takes you through the diagnostic instead — where the box sat, what your room was doing, and then what the pest is doing about ten days later.
The Orius are the exception: they are big enough to see, so the section above applies to them.

Questions about thrips total control - three stage system
Will I have bugs flying around my house?
No. They stay on the plants, where their food is.
Can I run these predators together?
Yes. They work side by side on real plants, and each one goes after the pest where it lives: swirskii takes the larvae on the leaves, Orius takes the adults in the flowers, and the nematodes take the pupae in the soil.
Can I use this if I already have sticky traps up?
Yes, with one adjustment. Blue sticky traps are worth keeping for monitoring, and they do catch adult thrips — but they catch Orius just as efficiently. Keep them at the room perimeter rather than inside the canopy, and pull them for about a week after an Orius release. Then put them back up and watch the adult count decline.
Is this safe for my plants?
Yes. These are naturally occurring biological controls. They do not feed on plant tissue, do not damage roots, and leave zero residue on your harvest.
When should I re-apply?
For a total reset, we recommend a follow-up release of Swirskii every 4 weeks to maintain the standing army. The Orius and Nematodes can be re-applied every 6 to 8 weeks depending on your pest pressure.
Can I use chemical sprays, Neem oil, or essential oils with this bundle?
No. Chemical pesticides, soaps, and oils are non-selective—they will kill your predatory mites and Orius just as quickly as they kill the thrips. How long you wait depends on the active: neem and horticultural oil only need to be dry, insecticidal soap a day, spinosad 14 days, sulfur 21, a synthetic pyrethroid 8–12 weeks. Release the Thrips Total Control bundle after whichever of those applies, and later still where the label says so.
How soon will I see results?
Unlike chemical sprays that provide an instant "knockdown," biological control is a system that works over time. What you are watching for is the population stabilizing first, then pest activity dropping. How long each stage takes depends on how heavy the pressure is. Patience is key—you are establishing a living army that will continue to hunt for you long after a spray would have evaporated.
How many Thrips Total Control kits do I need?
Count every plant in the space, not just the ones with damage. Pupae drop into whatever soil is underneath, so the nematode drench goes on every pot. Then pick the size that covers that count:
- X-Small: 10 plants
- Small: 25 plants
- Medium: 50 plants
- Large: 100 plants
- X-Large: 250 plants
- Heavy pressure (whole leaves silvered, adults lifting off in numbers): go one size up.
- Light pressure (a few flecks on one or two plants): one size down is fine.
- One kit is one release of all three. Check again at about two weeks; repeating the mites and nematodes then is the normal second round.
