Amblydromalus limonicus Slow-Release Prevention Sachets
10% off your first 4 orders, then 15% off every order after.
Bulk sachet discounts still apply to repeat orders — even if your cart doesn't show them.
Heads up—this is just an estimate. We only ship when the bugs are happy and ready to travel (Mon–Thurs). If a colony needs a beat to peak, or we're propagating a fresh batch, your order might hold up to a week. Treatment bottles jump the line when you've got an active infestation.
Amblydromalus limonicus Slow-Release Prevention Sachets
At A Glance
Amblydromalus limonicus is an aggressive, generalist predatory mite that serves as a highly effective, heavy-duty alternative for pest control in greenhouses and indoor gardens. Because these mites are larger and more voracious than many other predatory species, they are exceptionally good at suppressing both Whiteflies and Thrips. Our Slow-Release Sachets act as mini-factories, breeding and releasing a steady stream of hunters onto your plants for weeks.
-

How to Use
How They're Shipped
Hang them up, then wait.
How to deploy your sachets, and how to read the results over the next few weeks. Sachets are prevention — a slow-release nursery that ramps up over weeks, not a quick knockdown for an active outbreak.
-
01
Open the box right away
Bring the package indoors as soon as it arrives. Don't leave it on a hot porch, in a cold mailbox, or in direct sun. If you can't deploy immediately, set the sachets somewhere room-temperature (60–75°F) and out of direct light — they'll keep for a day or two.
-
02
Don't open the sachet
Each sachet is a self-contained breeding colony. The mites and their food source live inside; they emerge gradually through a small exit hole on the breathable face. Cutting the sachet open ends the slow release and dumps the colony all at once. Keep them sealed.
-
03
Hang or place near the plant
Hook each sachet on a sturdy branch, hang from a stake, or set near the base of the plant — out of direct sun and away from anywhere it'll get watered. Mites travel from the sachet onto the plant on their own. One sachet protects roughly 2–3 feet of canopy; see the product description for exact spacing.
-
04
Leave them alone for 4–6 weeks
Predator emergence ramps up over the first two weeks, peaks around weeks three to four, and tapers off through week six. You won't see the predators (they're smaller than a grain of salt), and an "empty-looking" sachet at week one means nothing. The real signal is what isn't happening — pests not establishing on protected plants.

Help! I'm overwhelmed
Yeah, it's a lot the first time you're using predatory mites. Please email us at info@fgmnnursery.com and we'll be happy to help!
I don’t see anything moving in my bottle or sachet. Does that mean they’re dead?
Not at all! In fact, go ahead and deploy them.
Predatory mites are microscopic (often less than 0.5mm) and naturally blend into their carrier medium (bran or vermiculite).
- For Bottles: The mites often huddle in the center of the bottle for insulation during transit.
- For Sachets: These are "slow-release" nurseries. The mites stay tucked deep inside the breeding media and emerge one by one over 2–4 weeks. Seeing an "empty-looking" sachet or bottle is not proof of a loss; it is simply how they are packaged for maximum survival.

Cucumeris: Why It Works (and Why It Fails)
Cucumeris is reliable, widely researched, and genuinely effective — within a specific set of conditions. Here's what it actually does, what it won't do, and how to tell if it's the right species for your situation.
My Plant Has Webbing. Help.
Webbing on a plant isn't always spider mites — and the mite that causes the most damage indoors doesn't produce webbing at all. Here's how to tell what you're actually looking at before you treat.
Native vs Invasive Ladybugs
Most ladybugs you'll encounter are red with black dots — and that description fits native, introduced, and invasive species equally. Here's how to actually tell them apart, what the harlequin ladybug has been doing to native populations, and where the real ecological concerns are.
