Horiver Dry - White

Horiver Dry – White Sticky Traps — 20 × 40 cm - Monitoring & Trapping for Flying Insect Pests
Horiver Dry – White Sticky Traps are designed for clean, high-contrast monitoring of flying insect pests in greenhouses, nurseries, interiorscapes, and outdoor growing areas. Each card features a dry adhesive surface that holds pests securely without staining hands or plants. The large 20 × 40 cm format offers generous capture area for high-visibility scouting and trend tracking. This format is ideal for high-pressure zones and large-scale plant areas, integrating seamlessly into IPM programs for early detection, scouting, and population tracking.

Use For
Horiver Dry – White traps target a wide range of flying pests, including:

Whiteflies (Trialeurodes vaporariorum, Bemisia tabaci)
Leafminers (Liriomyza spp.)
Fungus gnats and sciarids (Bradysia spp.)
Shore flies (Ephydridae spp.)
Lygus spp. (especially effective compared to yellow traps)

Traps placed near vents, doors, and perimeter areas can intercept airborne introductions before colonization.

When to Use Horiver Dry – White
Use Horiver Dry – White year-round. 

Recommended For:
Continuous monitoring of problem populations
Early detection before pressure escalates
Post-treatment or biocontrol performance checks
Placement in high-risk zones like doors, vents, and perimeter areas

How It Works
Mode of Action: Trapping via color attraction and adhesive capture
Behavior: Flying insects are drawn to the white color and become stuck on contact
Visual Effect: Pests are immobilized on the trap surface, providing a clear visual indicator of pressure

Monitoring Value:
Reveals pest presence, density, and movement trends
Supports timely biological control decisions
Reduces reliance on chemical interventions when paired with scouting

Placement Rates

Trap Placement & Monitoring Strategy
Hang traps evenly at or just above canopy height
Focus on entries, vents, benches, and known hotspots
Replace cards weekly or when surfaces become saturated

Best Working Conditions
Temperature: Effective across all growing environments (32–104°F)
Humidity: Works in dry or humid conditions
Plant Compatibility: Suitable for indoor, greenhouse, and outdoor plants

Compatibility Guidance
Safe for use with all biological control agents
Compatible with chemical controls

Product Specifications
Card Dimensions: 20 × 40 cm
Adhesive Type: Dry glue (non-staining)
Color: White (high-contrast monitoring)

Storage & Handling
Store flat in a cool, dry place away from direct sunlight
Keep protective liners on until installation
Handle edges to avoid contaminating adhesive surface

What to Expect
Immediate attraction and capture of flying pests
Clear visual indication of pest pressure
Enhanced scouting accuracy when integrated with biological controls
Replace traps weekly or as needed based on pest load

Recommended IPM Pairings
Biological controls such as Swirskii sachets for thrips and Entomite-M for fungus gnats
Use in tandem with scouting guides
Combine with yellow or blue sticky traps for targeted pest monitoring
Ideal for use alongside sachets and bottle-format predators

FAQs
What pests does the white card help monitor?
White cards are commonly used for whiteflies, leafminers, fungus gnats, shore flies, and Lygus spp.

How many traps should I use?
Follow action rate guidelines:

Light pressure: 1 card per 10 sq. ft
Heavy pressure: 2–3 cards per 10 sq. ft
Increase density in hotspots and near entry points.

Where should I place the traps?
Hang at or just above canopy height, near vents, doors, benches, and known hotspots. Avoid banker plants and beneficial release zones.

Will these impact beneficials?
Sticky traps may occasionally capture flying beneficial insects. To minimize this, release beneficials away from trap locations.

How does white compare to yellow sticky traps?
White cards: Especially effective for Lygus spp. and provide clean, high-contrast monitoring with dry glue (no staining).
Yellow cards: More attractive to whiteflies, thrips, and other pests.
