Bug Ball Starter Kit

The Bug Ball Starter Kit includes two heavy-duty PVC Bug Balls, plus an 8-ounce Catch EM’ spray-on coating and two inflation needles. It takes 2-3 balls to cover about one acre. Best for buyers seeking a simple entry point with a ready-to-use sticky coating. This kit targets yellow flies, horse flies, deer flies, greenhead flies, and other biting insects. Suitable for homes with pets and kids due to no pesticides or electricity required.
Best for: new buyers or households wanting an all-in-one setup with coating included. It’s a balanced option for medium outdoor spaces and bug-prone yards. Caution: ensure stable storage of inflation needles to prevent misplacement.
Bug Ball Replacement Ball (3 Pack)

The Replacement Ball 3-pack is designed for ongoing pest control with three heavy-duty PVC balls and inflation needles. It takes 2-3 balls to cover 1 acre and works with Catch EM’ sticky coating (sold separately). Safe for homes with children and pets. This option is ideal for replenishing an established setup without buying a full kit again.
Best for: existing Bug Ball users who need quick replenishment. A potential limitation is that the Catch EM’ coating is sold separately, so plan for a complete setup in one purchase.
Mysora 2 Pack Inflatable Fly Trap Balls

The Mysora set includes two PVC trap balls and an air pump, designed to reduce black, yellow, and greenhead flies outdoors. Glue/coating is not included, but the kit is compatible with sticky coatings for capture. These traps are non-electric and suitable for barns, gardens, and greenhouses. Durable and weather-resistant, they tolerate outdoor conditions well.
Best for: buyers wanting a straightforward, electric-free option with quick setup in barns or yards. Caution: glue or sticky coating must be purchased separately for trapping effectiveness.
Bug Ball Deer Fly Ball Deluxe Kit

The Deer Fly Ball Deluxe Kit provides three Deer Fly Balls, three inflation needles, and a Catch EM’ spray-on sticky coating. Coverage is 2-3 balls per acre to tackle deer flies, horse flies, stable flies, and similar pests. It’s designed to work with Catch EM’ and offers a safe option for households with children and pets. A potential limitation is that it targets large flies primarily; smaller biting insects may require additional units.
Best for: properties with deer fly activity or sunlit fields near pastures. Choose this if deer flies are the primary concern and you want coating included for immediate use. Avoid this if you need a broad-spectrum solution for many small biting insects in a compact space.
Bug Ball Replacement Kit

Best for: continuing control of biting flies in established trap systems. Limitation: coating sold separately can add to the total cost if not previously included in a bundle.
Bug Ball Starter Kit (3-Pack)

Starter Kit includes three Bug Ball traps, three inflation needles, and one Catch EM’ brush-on sticky coating. Coverage is 2-3 Bug Balls per acre. The kit relies on Catch EM’ coating for effective trapping and is safe for families and pets, with no pesticides or electricity needed. This option offers a balance of quantity and cost for growing outdoor spaces.
Best for: medium to larger outdoor areas needing a scalable, pesticide-free trap system. Choose this if you want a high-capacity starter that can be expanded with replacements as needed. Caution: ensure you have enough Catch EM’ coating on hand for optimal results.
Buying Guide: Key Purchase Considerations
What should you consider when choosing a horse fly trap ball system?
- Coverage and scalability: How many bug balls are needed per acre? Look for product sets that specify 2-3 balls per acre as a benchmark and consider future expansion with replacement kits.

- Ease of use: Look for sets with inflation needles and simple setup. Non-electric options save energy and reduce maintenance.
- Target pests: Different products emphasize deer flies, horse flies, yellow flies, or greenhead flies. Pick traps aligned with your most problematic species.
