How Do You Keep Spider Mites And Thrips From Coming Back?

You cleared the thrips. The webbing’s gone. That twisted new leaf finally unfurled normally.

Now what?

You’ve seen how fast spider mites, broad mites, russet mites, and thrips can spiral out of control—and you don’t want to go through that again. These sachets are how you stay ahead of it.

Biological Pest Prevention for Spider Mites, Broad Mites, Russet Mites, Thrips, and More

These sachets release live predatory mites gradually over 3–5 weeks to prevent pests from establishing in the first place. No sprays. No mixing. No guesswork.

If you’ve ever dealt with an infestation—or just want to avoid one—this is your slow-release insurance.

Each sachet contains four species of beneficial mites, selected to cover multiple pests, microclimates, and plant types. The mites emerge over time, spread throughout your foliage, and quietly take out pests while they’re still in egg or larval form.

You won’t see the mites. You also won’t see the pests. That’s the point.

What It Prevents

This mix is especially helpful if:

• You aren’t sure what pests you’ll be dealing with

• You’ve cleared an infestation and want protection

• You grow in a warm, humid space with lots of foliage

• You want to stop spraying and try natural prevention instead

What's Inside

Each sachet contains a balanced mix of four compatible predatory mite species:

• Amblyseius swirskii – Targets thrips (eggs + larvae), whiteflies, broad mites, russet mites

• Amblyseius cucumeris – Thrips larvae, broad mites, cyclamen mites

• Amblyseius andersoni – Spider mites, broad mites, cyclamen mites; climate-flexible

• Phytoseiulus persimilis – Specialist spider mite predator (Tetranychus spp.)

Each species plays a different role—some dominate in heat, others tolerate cold. Some feed on eggs, others on mobile juveniles. Together, they give you coverage across pests before damage is visible.

How It Works

Sachets are designed for biological slow-release. Each one contains a mix of:

• Adult predatory mites

• Juveniles

• Eggs

• A food source (bran + supplemental feed)

Here’s what happens:

1. Mites exit the sachet gradually through the vent

2. They crawl onto leaves and stems, seeking pest eggs and larvae

3. Adults feed and reproduce

4. New generations emerge and continue hunting

5. Coverage lasts 3–5 weeks depending on temperature and humidity

No spraying. No reapplication during the active release period.

How to Use

• Do not open the sachets. Mites exit naturally through the release hole.

• Hang sachets near foliage, but above the watering line—do not soak.

• Works under both grow lights and natural light.

Best Conditions for Success

If your environment is dry, mist near (not on) plants or use a humidifier to improve mite emergence and reproduction.

Pro Tips

• Start early. Don’t wait for visible pest symptoms—these are for prevention.

• Pair with Good Bug Diet if you’re using sachets preventatively in low-pest conditions.

• Use sachets after bottles to maintain control after knockdown.

• Stay on schedule. Especially during spring, summer, and early fall.
