Limitation: Glue-based systems may require periodic replacement if exposure to heavy rains or direct sun reduces stickiness.
Buying Guide: Key Purchase Considerations
- Target pests: Identify if your area has deer flies, horse flies, yellow flies, greenhead flies, or other biting insects to choose the most effective trap type.
- Coverage needs: Estimate acres and the number of traps required (2-3 traps per acre is a common rule) to avoid gaps in protection.
- Coating and maintenance: Many kits rely on Catch EM’ sticky coating sold separately. Consider whether you prefer ready-to-use coatings or buying components separately.
- Placement strategy: For best results, place traps away from direct wind paths, near problem areas like gates, feeding zones, and barn entrances.
- Safety and practicality: All items listed are designed to be kid- and pet-safe when used as directed; ensure proper storage and handling of coatings.
- Weather resilience: If you operate in regions with heavy rain or sun, prioritize weather-resistant PVC or material that maintains adhesion under varying conditions.
- Future scalability: If insect pressure fluctuates seasonally, choose a kit that allows expanding coverage with additional traps or replacement balls.
