Catchmaster GRO Yellow Large Double-Sided Sticky Traps 50-Pack — UV & Water-Resistant, Ready-to-Use Plant Pest Control

Catchmaster GRO Yellow Large Double-Sided Sticky Traps are ready-to-use adhesive cards that capture flying and crawling plant pests around homes, greenhouses, gardens, and hydroponic setups.

These bright yellow, double-sided sticky cards from Catchmaster provide a simple, chemical-free way to monitor and reduce populations of common pests such as fungus gnats, whiteflies, fruit flies, thrips, aphids, sciarid flies and small moths. Each trap arrives pre-coated with an odorless, UV- and water-resistant adhesive designed to stay tacky through normal greenhouse and garden conditions. The thin, lightweight cards can be staked, tied, or rested against surfaces for flexible placement indoors or outside.

How do these sticky traps protect plants without pesticides?

The traps use color attraction and strong adhesive to intercept insects before they can feed or reproduce on your plants. Because they are mechanical traps, there are no active chemical ingredients and no residue on foliage.

• Double-sided adhesive increases capture surface area for better interception.
• Yellow color attracts many common plant pests that seek foliage.
• Water- and UV-resistant glue maintains effectiveness in typical growing conditions.
• Ready to use — no bait or mixing required.

Where should I place these traps for best results?

Strategic placement is key: position traps at multiple canopy levels and near known infestation points to both monitor and reduce pest numbers. For maximum coverage use a three-zone approach—below canopy, mid-canopy and above canopy.

• Stake in soil or tie to plant stems around beds and pots.
• Place along greenhouse aisles, barn walls, or near compost and trash areas.
• Use several traps per area to improve detection and capture rates.
• Replace or rotate traps when heavily covered or after prolonged exposure.

How long will a trap remain effective and how do I maintain them?

Catchmaster sticky cards are designed to remain effective up to about one year, depending on environmental debris and sun exposure. Keep the adhesive surface clean of dust and soil for longest life; if the surface becomes clogged, swap the card for a fresh one.

• Effective up to one year in ideal conditions; replace when full of insects or dirty.
• Resistant to moisture and UV helps prevent rapid breakdown outdoors.
• Dispose of used cards responsibly; adhesive is non-toxic but not meant for ingestion.
• Combine with cultural controls and monitoring for integrated pest management.

These sticky traps suit indoor houseplants, greenhouse benches, hydroponic and aeroponic systems, outdoor vegetable beds, orchards, and barns.
