Product Details
Entomite-M (Stratiolaelaps scimitus) — Soil-Dwelling Predator for Fungus Gnats & Thrips Pupae
Entomite-M contains Stratiolaelaps scimitus, a soil-dwelling generalist mite that targets fungus gnat larvae, thrips pupae, and other pests developing in soil or growing media. These predators actively patrol the top half-inch of soil or potting media, feeding on pest stages that foliar sprays and sticky traps can’t reach. Use Entomite-M as a potting amendment or sprinkle it on the soil surface for preventative and curative control in any growing environment.
Entomite-M is chemical-free and safe for use in any growing environment including greenhouses, nurseries, orchards, flower beds, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.
Key Advantages:
Targets hidden pests: Controls larvae and pupae in soil where sprays fail
Broad compatibility: Works with sticky traps, BTI drops, and beneficial nematodes as well as other beneficial predators
Low maintenance prevention: Works silently and out of view in your soil or potting medium to rid plants of fungus gnat larvae and other harmful soil dwellers.
Use For
Entomite-M feeds on soil-dwelling stages of:
• Fungus gnats (Bradysia spp.) — eggs, larvae, and pupae
• Thrips (Frankliniella occidentalis, Thrips tabaci, and others) — pupae in soil
• Root aphids — immature stages
• Springtails and other small soil invertebrates (in moderation/opportunistically and when no other prey is present)
When to Use Entomite-M
Use wherever soil-dwelling pests and/or fungus gnats are present or anticipated. Effective across all growing environments.
Recommended for:
Preventative incorporation into potting media during transplanting
Active control of Fungus gnats
Thrips management programs targeting pupal stages in soil
Root aphid control
Growers seeking long-term prevention & control
How It Works
Mode of Action: Nymphs and adults pierce and consume larvae and pupae in the top half inch of soil
Behavior: Predators actively search for prey in the top-layer of soil
Visual Effect: Pest populations decline steadily as mites establish and feed
Feeding Behavior & Rates
Larvae: Non-feeding stage
Nymphs and Adults: Feed on fungus gnat larvae, thrips pupae, immature root aphids, and other small soil invertebrates
Feeding Rate: Adult females consume up to 4.5 thrips pupae per day under optimal conditions
Lifecycle of Stratiolaelaps scimitus
Egg Stage
White, oblong; laid in moist soil
Hatch in ~6 days at 68°F
Larval Stage
Non-feeding; six-legged, white
Short duration before molting
Nymphal Stages
Eight-legged, light brown; actively feed
Feeding duration: ~10 days
Adult Stage
~1 mm, beige with brown shield; actively Feed
Lifespan: Several weeks; females lay ~2 eggs/day
Release Rates & Application
Pressure Level Definition Rate per 10 sq ft Repeat Interval Preventative No visible fungus gnats or pest pressure 100–200 mites Every 4 weeks, or upon repot Low Pressure Early signs of fungus gnats or thrips pupae 200–300 mites Every 4 weeks, or upon repot Medium Pressure Multiple areas affected; moderate pest activity 300–400 mites(paired with foliar predator) Every 3 - 4 weeks, or upon repot High Pressure Widespread pest presence; visible damage or high trap counts 400–500 mites (paired with foliar predator) Every 3 - 4 weeks, or upon repot
Application Notes:
Tilt on side & rotate container gently before use to distribute predatory mites evenly within the container
Apply directly to soil or incorporate during transplanting
Avoid watering 10 minutes before and for a few hours after release
For cabinets, greenhouses and other areas where fungus gnats are harboring in non-plant material; Distribute into crevices, under benches, and around pipes
Best Working Conditions
Temperature: Minimum 59°F; optimal 68–77°F
Compatibility Guidance:
Allow residues from oils or soaps to dry before application

What to Expect
Entomite-M begins working immediately as these predatory soil mites patrol and feed. For curative control of fungus gnats combine with sticky traps. If sticky traps catch large amounts of fungus gnats per week introduce Entonem for increased control. For control and prevention of thrips combine with Swirskii, Thripor, or Thripex.
Recommended IPM Pairings:
Horiver Yellow sticky traps for adult fungus gnat monitoring
Thripor or Thripex for foliar thrips control
Generalist foliar mites (Swirskii, Limonicus, Andersoni)and/or Thripor (Orius spp.) for full thrips control
Entonem (Steinernema feltiae) for enhanced fungus gnat larval suppression
Atheta (Dalotia coriaria) for broader soil pest coverage
Microbial dips (Microflora SA) for propagation trays
FAQs
Can I store this for later?
Long-term storage, i.e. more than 48 hours, is not recommended. Apply promptly after receipt. Our products are shipped fresh for immediate use to ensure maximum performance. If needed, keep in a cool, dark, dry place for up to 1–2 days; longer holding reduces effectiveness and quality.
Does Entomite-M contain adults?
Yes—includes predatory nymphs and adults which actively feed.
Is Entomite-M safe for indoor crops?
Yes—safe for people, pets, and plants; ideal for enclosed environments.
How soon will I see results?
Feeding begins immediately; control builds quickly as predators move through soil.
Can I use Entomite-M with other beneficials?
Yes—pairs well with foliar predators and microbial products. For thrips control, pair Entomite-M with foliar predators like Swirskii, Thripor, or Thripex for comprehensive curative control.
Can I apply it to greenhouse floors or under benches?
Yes—sprinkle into crevices around pipes, and workbenches.Questions about Entomite-M?
