Scarid 10 - Fungus Gnat Treatment

What is Scarid 10 and how does it work?

Scarid 10 is a professional residual insecticide designed to target fungus gnat larvae in the root zone. It disrupts the pest life cycle by preventing eggs and larvae from maturing, helping stop ongoing infestations at the source.

Does Scarid 10 kill adult fungus gnats?

Scarid 10 primarily targets larvae in the growing medium. It helps reduce adult populations over time, but for immediate adult control, pair it with sticky traps and environmental adjustments.

How quickly does Scarid 10 work, and how long does it last?

You'll typically notice fewer adults within a few days as larvae are eliminated. Scarid 10 leaves a residual effect in the treated media, but exact longevity depends on watering and media type.

Can I use Scarid 10 in soil, coco, or hydroponic systems?

Yes—Scarid 10 is suitable for use in soil, coco, peat-based mixes, and hydroponic systems (including DWC and RDWC). Always follow the specific application method for your setup.

What’s the correct way to apply Scarid 10?

You can apply it as a soil drench (5 mL/L), a hydro flush (0.5 mL/L with a clean tank, circulate 2 hours, then dump), or a preventative surface spray (30 mL/L weekly on the medium).

Is Scarid 10 safe for seedlings or clones?

Yes, but young plants can be more sensitive. Avoid splashing foliage and stick to label rates. Always treat semi-dry media and avoid overuse.

Will Scarid 10 harm beneficial microbes or predatory insects?

It can. Scarid 10 is a broad-spectrum insecticide, so it may affect beneficials in the treated zone. If you're using biological controls, apply them after treatment or rotate between methods.

Is Scarid 10 organic or natural?

No. Scarid 10 contains deltamethrin, a synthetic pyrethroid. It’s effective but not a natural or organic product—use it where biologicals aren’t cutting it or as part of a rotation.

Is Scarid 10 safe around pets or aquariums?

Use with caution. Keep pets away during application and drying. Avoid use near aquariums, as pyrethroids are harmful to aquatic life. Always ventilate treated areas.

Do I need gloves or PPE when using Scarid 10?

Yes—wear gloves and avoid breathing mist. Scarid 10 is a real insecticide, not a foliar tonic. Apply to the medium only, and ensure good airflow in enclosed spaces like grow tents.

Can Scarid 10 be used long-term or in an IPM routine?

Yes, but it’s best used as a targeted tool. For long-term success, pair with sticky traps, environmental fixes, and rotate with gentler options like BTI or nematodes.

How can I prevent fungus gnats from coming back after treatment?

Let the surface dry between waterings, clean up algae or moss, use sticky traps, bottom-water when possible, and avoid overwatering. Scarid 10 works best alongside good growing habits.

What if Scarid 10 doesn’t seem to be working?

Check for missed areas, poor watering habits, or reinfestation from untreated pots. Scarid 10 helps stop larvae, but you need to address environmental causes for lasting results.

How much Scarid 10 do I need for different setups?

For a 10L drench: 50 mL. For a 20L hydro flush: 10 mL. For a 10L preventative spray: 300 mL. Stick to label rates—don’t increase strength, as overuse can stress plants or harm soil life.

How should Scarid 10 be stored?

Keep the bottle sealed, upright, and out of heat and sunlight. Don’t premix large batches—diluted solutions are best made fresh for accuracy and stability.
