Horiver Yellow Sticky Discs — 18 cm Diameter - Monitoring & Trapping for Soil-Emerging Pests
Horiver Yellow Sticky Discs are designed to monitor and trap soil-emerging insect pests such as root aphids and fungus gnats in a variety of growing environments, including greenhouses, indoor spaces, and hydroponic systems. Each disc is made of durable polystyrene and coated with high-tack dry glue for reliable adhesion. The 18 cm diameter format offers broad coverage around plant stems, making it ideal for precise monitoring at the substrate level.
A pack includes 50 discs. Discs are placed individually around plant stems for targeted interception of pests emerging from soil or media.

Use For
Horiver Discs target pests that emerge from soil or substrate, including:

Root aphids (Pemphigus spp., Aphis spp.)
Fungus gnats and sciarids (Bradysia spp.)

How It Works
Mode of Action: Trapping via color attraction and adhesive capture
Behavior: Soil pests are drawn to the yellow color and become stuck on contact
Visual Effect: Pests immobilized on the disc surface provide a clear indicator of pest pressure

Trap Placement & Monitoring Strategy
Placement Height: Lay discs flat on substrate surface, centered around plant stem

Application Steps:
Remove silicone cover from one side and place disc sticky-side down around the stem, just above the substrate
Remove silicone cover from the top side to expose adhesive

Best Working Conditions
Temperature: Effective across all growing environments
Humidity: Dry glue remains tacky even in high humidity
Plant Compatibility: Suitable for indoor, greenhouse, and outdoor plants
