Swirski-Mite PLUS Sachets

Placement Tips:
• Hang sachets in sheltered spots, away from direct sun or heat
• Hold by cardboard strip to avoid damage
• Do not open sachets—exit hole is pre-made
• Open shipping box in crop and tear sachets along perforations
• For vertical crops/tall plants, place sachets above and below pest hotspots

Best Working Conditions
Temperature: Active from 59°F to 97°F; optimal range 68–90°F
Reproduction Peak: Fastest at 86°F
Humidity: Optimal at 63% RH or higher

Compatibility Guidance
• Avoid broad-spectrum pesticides before and after release
• Allow residues from oils or soaps to dry before application
• Compatible with Orius spp. and whitefly parasitoids
• Do not combine with other generalist predatory mites (Neoseiulus cucumeris, Amblydromalus limonicus, Transeius montdorensis, Amblyseius andersoni)
• May feed on eggs of other Type III mites and Aphidoletes aphidimyza—plan accordingly
• For compatibility details, check our Natural Enemies - Chemical Compatibility and Beneficial Insect & Pesticide Compatibility Table

Environmental Impact & Sustainability
Swirskii-Mite PLUS sachets support sustainable growing practices by replacing chemical sprays with natural predators. While not compostable like Ulti-Mite sachets, PLUS sachets still reduce pesticide runoff, protect pollinators, and maintain ecological balance across growing environments.

What to Expect
• Swirskii-Mite PLUS sachets release predators consistently after placement
• Thrips, whiteflies, and pest mites are suppressed as predators feed
• Predators disperse through foliage for 4–6 weeks
• Reapply based on scouting observations to maintain control and prevent resurgence

Recommended IPM Pairings
• Horiver Yellow sticky traps for flying pest monitoring
• Limonica or Orius spp. for layered thrips control
• Isarid Mycoinsecticide for knockdown in high-pressure zones
• Knowing and Recognizing book for pest ID and scouting reference
• Swirskii-Mite bulk bottles for curative coverage and hotspot targeting

FAQs

Do Swirskii-Mite Ulti-Mite contain adult mites?
Yes—sachets contain a mix of life stages, including adults, juveniles and eggs.

Is Swirskii-Mite safe for indoor plants?
Yes—completely safe for people, pets, and plants, making it ideal for use in enclosed environments like homes, offices, herb gardens and interiorscapes.

How soon will I see results?
Feeding begins immediately after release. In warm, humid conditions, suppression accelerates rapidly—visible pest reduction often begins within 2–3 days. Mites actively hunt and consume pest eggs and larvae, targeting hotspots with high efficiency. For best results, apply during early signs of pressure and monitor pest decline through scouting or sticky traps.

Can I use this on tomatoes?
Swirskii is not recommended for tomato crops. Tomatoes have natural resistances to certain predators, making it difficult for Swirskii to maneuver and hunt on the plant. There is no harm to using Swirskii in any set-up, however Swirskii’s performance in tomatoes is subject to the specific species of tomato and its maturity. For tomatoes we recommend using Thripex sachets to control thrips and Spidex to control spider mites. These predators can navigate mature tomato plants.

What is the difference between Plus and Ulti-Mite Sachets?
Ulti-Mite sachets are made from compostable film and tolerate humidity and temperature fluctuations. PLUS sachets are made from paper and should only be used in stable environments. Ulti-Mite is the preferred choice in most scenarios.
