Bug Ball Deer Fly Ball Replacement Kit - 3 Pack Replacement Traps

Our review of the Bug Ball Deer Fly Ball Replacement Kit finds it best suited for homeowners and small property owners who need a low-effort, pesticide-free way to reduce biting flies near patios, stables, and gardens. The single biggest reason to buy is its straightforward, reusable design: heavy-duty PVC balls that hang where flies naturally congregate and hold them on an odorless sticky coating. For anyone seeking a mechanical, non-electric solution to deer flies and horse flies, this replacement pack supplies multiple traps and the inflation needles required to keep them serviceable.

Key Features

• Replacement Pack: Includes three deer fly ball traps and three inflation needles so you can service multiple locations or rotate traps as needed.
• Coverage Guidance: Each ball is sized to contribute to coverage of about 1 acre when using two to three balls, giving a practical rule of thumb for placement across yards or small pastures.
• Sticky Coating Compatibility: The trap is designed to work with Catch EM sticky coating, which is odorless and requires no pesticides or electricity to immobilize biting insects.
• Durable Construction: Heavy-duty, weather-resistant PVC stands up to outdoor conditions and lets traps remain deployed near pools, barns, or orchards.
• Simple Setup: Inflate, coat with sticky material, and hang using the molded loop; recommended hanging height is roughly 4-5 ft in sun next to shade for best results.
• Target Effectiveness: Particularly effective on deer flies, horse flies and black flies, making it suited to areas where those biting insects are a recurring problem.

Who It's For

This kit is for backyard owners, gardeners, and small livestock keepers who want a low-maintenance, non-chemical option to reduce biting flies around people and animals. It is useful for anyone who can hang traps from trees, poles, or structures and who will reapply a sticky coating every 2-3 weeks for peak performance.

It is less suitable for large-scale commercial operations that require electronic or pesticide solutions, or for buyers who prefer a fully ready-to-use system with included sticky coating; this kit supplies the balls and needles but assumes the user will acquire Catch EM sticky coating separately if not already on hand.

Pros & Cons

Pros

• Effective at catching deer flies and horse flies when used with a sticky coating.
• Durable PVC construction that tolerates outdoor exposure.
• Includes inflation needles to keep traps serviceable without extra parts.

Cons

• Sticky coating is sold separately, so the kit is not a complete kill solution out of the box.
• Some users report applying the sticky coating can be fiddly and require patience to get even coverage.

Our Verdict

The Bug Ball Deer Fly Ball Replacement Kit is a practical, cost-effective choice for homeowners and small property owners who want a non-chemical way to reduce biting flies.

No, the balls are sold without sticky coating; they are designed to be used with Catch EM sticky coating which is sold separately.

Manufacturer guidance suggests 2-3 balls to effectively cover about 1 acre, so smaller yards will need fewer traps.
