Horiver Discs

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
Trap Saturation: Replace discs weekly or when surfaces become saturated with insects or debris
Monitoring Frequency: Check discs at least once per week
Record pest counts to track trends and inform release timing of biological controls
Dynamic Adjustment: Increase disc density in hotspots or high-pressure zones
Perimeter Monitoring: Combine discs with sticky cards near doors and vents to intercept windborne pests and prevent secondary infestations.

Best Working Conditions

FAQs
What does “pressure” mean?
Pressure refers to pest population levels:

Preventative: No pests detected; proactive monitoring
Low Pressure: Few pests detected; early-stage presence
Medium Pressure: Moderate pest counts; localized hotspots
High Pressure: Heavy pest presence; widespread risk

How many discs should I use?
Follow action rate guidelines: one disc per plant for preventative and active monitoring. Increase density in high-risk zones or where pest pressure is escalating.

Are these traps safe for beneficials?
Sticky surfaces may occasionally capture flying beneficial insects such as parasitic wasps. To minimize this, release beneficials away from disc locations. Despite this minor risk, discs remain essential for early detection and accurate population tracking.

Can these detect pests other than root aphids and fungus gnats?
Horiver Discs are optimized for soil-emerging pests. While they primarily target root aphids and fungus gnats, they may also intercept other crawling pests near the substrate.

What makes discs different from sticky cards?
Discs are designed for horizontal placement at soil level, directly around plant stems, making them ideal for pests emerging from substrate. Sticky cards, by contrast, monitor flying pests above the canopy.
