Horiver Professional Sticky Traps

At A Glance

Horiver sticky traps are the industry standard for IPM (Integrated Pest Management). Whether you are monitoring for early infestations or actively working to reduce flying pest populations, these professional-grade traps are the most reliable tool in your arsenal. With a high-tack, non-drying glue that remains effective in high-heat and high-humidity environments, they are designed to be the "eyes and ears" of your growing space.

  • Product Type: Sticky Trap (Monitoring & Mass Trapping).

  • Pack Size: 10 or 12 traps per pack

  • Key Advantage: Professional-grade glue that does not dry out, drip, or lose tackiness.

  • Compatibility: Completely pesticide-free and safe to use alongside predatory mites and insects.
Which Horiver is right for you?

Answ

Blue Trap (12 Pack): The Thrips Specialist. Blue is the mandatory wavelength for monitoring and trapping flying adult thrips.

Yellow Trap (10 Pack): The Generalist. High-attraction for Fungus Gnats, Whiteflies, and Shore Flies.

White Dry Trap (10 Pack): The Leafminer Specialist. Specifically targets leafminers without confusing the beneficial wasps you might be using.

Sticky Discs (10 Pack): The Precision Tool. Perfectly sized for small individual pots, cloning trays, or tight spaces where a full-sized card won't fit.
The Color-Coded Trap Guide

Pest behavior is wavelength-specific. Using the correct color is the difference between catching nothing and catching everything.

  • Blue Horiver (Thrips Specialist): Specifically tuned to the wavelength most attractive to Western Flower Thrips and other thrips species.Available in 10x25cm and 25x40cm.
  • Yellow Horiver (General Purpose): High-attraction color for a wide range of flying pests including Fungus Gnats, Whiteflies, and Shore Flies.Available in 10x25cm.
  • White Horiver Dry (Leafminer Specialist): Designed specifically to attract Leafminers without attracting beneficial wasps that might be confused by yellow or blue.
  • Horiver Discs: Smaller, circular versions of the above technology. Perfect for localized monitoring on individual pots, around the base of plants, or in tight grow tents.
Best Placement Practices

Height Optimization: Always place traps 2–4 inches above the canopy. As your plants grow, raise the traps to keep them at the "top" of the foliage level where pests are most active.

Entry Points: Place traps near known entry points (doors, air intake fans, or ventilation) to intercept "hitchhiking" pests before they settle on your crops.

The Canopy Line: Pests follow the tops of leaves. Placing traps at the same height as the canopy maximizes your capture rate.

Discs vs. Cards: Use Discs for tight spaces, individual house plants, or around the base of the stem. Use Cards for larger vertical runs in greenhouses or grow rooms.
Selection Guide

Use this guide to choose the right tool for your specific pest pressure:

  • For Thrips: Use Blue Cards or Discs. Blue is the mandatory color for monitoring and trapping flying thrips adults.
  • For Fungus Gnats & Whiteflies: Use Yellow Cards or Discs. Yellow is highly effective for early detection of these pests.
  • For Leafminers: Use White Dry Cards. This color attracts leafminers while leaving beneficial wasps unharmed.
  • For Monitoring: Use Discs or the 10x25cm cards. Place 1 trap per 50 square feet to act as your early warning system.
  • For Mass Trapping: Use the large 25x40cm Blue Cards. When dealing with an active outbreak, use 1 trap per 5–10 square feet to aggressively reduce the flying adult population.
Storage and Handling

Handle by Edges: The glue is exceptionally sticky. Handle traps by the edges or the non-sticky border to avoid getting glue on your fingers.

Keep Cool: Store in a cool, dry place away from direct light to maintain the tackiness of the glue.

Disposal: Once the surface is covered in pests or dust, remove and replace. These are single-use tools.

FAQ

Why use Blue for Thrips and Yellow for everything else?

Thrips are specifically attracted to blue light frequencies. If you use yellow traps for thrips, you will catch significantly fewer pests. Always use blue when thrips are the priority.
Why use White (Dry) traps?

Standard sticky traps can sometimes catch the beneficial parasitic wasps you are trying to use to fight leafminers. White traps are "blind" to those beneficials while still being highly attractive to leafminers.
Will these get rid of my infestation completely?

Sticky traps are a monitoring and suppression tool, not a "cure." Use them to reduce the flying adult population, but always pair them with biological controls (like beneficial mites or nematodes) to kill the eggs and larvae.
Are they safe for my pets?

Yes, but they are extremely sticky. Keep them well out of reach of furry pets. If glue gets into pet fur, it can be very difficult to remove.
How often should I replace them?

Replace them every 4–6 weeks, or sooner if the trap is fully covered in dust or pests.
What if I don't catch any pests on my traps?

If your traps are clean, that is actually a great sign! It means your garden is currently free of flying adult pests. Sticky traps are just as important for confirming your garden is healthy as they are for catching bugs. Keep them up as a preventative "early warning system"—if a pest suddenly appears, you’ll catch it on day one before it becomes an infestation.
