Flowtron Outdoor Bug Zapper — 120W UV, 2-Acre Coverage, 5,600V Grid with 450‑Hour Octenol Cartridge

Flowtron's 120W Outdoor Bug Zapper is a heavy-duty electronic insect control unit that uses three UV bulbs, an octenol cartridge, and a 5,600‑volt shock grid to manage flying pests across up to 2 acres.

Designed for large yards, farmlands, patios and wooded lots, this Flowtron model combines multiple insect-attraction methods with a high-voltage elimination grid in a weatherproof housing. It is powered by a transformer-driven shock system and includes a slow‑release octenol attractant cartridge (450-hour) to extend reach. The unit is UL listed, EPA-registered and built to resist outdoor elements without relying on sprays, sticky materials, or messy catch trays.

How does this unit pull bugs in and remove them?

The zapper uses two complementary lures: three 40W ultraviolet blacklight bulbs to draw phototactic insects, plus a slow-release octenol cartridge that imitates human/animal scents to attract biting species. Once in range, insects contact a supercharged 5,600‑volt grid that delivers an instant kill and avoids mesh clogging.

• Three 40W UV bulbs for long-range visual attraction.
• Included 450-hour octenol cartridge for mosquito and biting insect appeal.
• 5,600V transformer-powered grid for immediate elimination.
• Non-clogging design sends remains to the ground—no interior buildup.

What area will it protect and where should I place it?

This Flowtron covers roughly 2 acres in typical outdoor wooded or yard settings and about 2,000 sq ft for open or semi-enclosed spaces when used near living areas. Placement matters: locate it downwind and away from human activity to pull pests away from people and pets.

• Effective up to 2 acres in wooded or high-pressure pest environments.
• Recommended 2,000 sq ft coverage for close‑in yard and patio use.
• Mount on a post or hang 4–6 feet high and away from gathering spots.
• Do not use octenol cartridge indoors—outdoor use only.

How does the design make maintenance and durability easier?

Flowtron engineered this model to be low-maintenance and weather-tolerant. The polycarbonate housing resists rust, cracking and fading while the no-bag/no-tank approach means there are no sticky trays or liquids to empty; most debris falls beneath the unit.

• Rugged weatherproof polycarbonate housing for long outdoor life.
• Zero chemicals, fogs or adhesive strips—environmentally friendlier operation.
• No internal receptacle to clean regularly; insects fall away automatically.
• UL listed and EPA registered for compliance and safety assurance.

Is the high-voltage grid safer or better than lower-voltage models?

The transformer-powered 5,600V grid is designed to kill instantly and reduce short circuits common in lower-voltage units. That higher voltage improves performance on larger or more resilient insect species and minimizes the chance of insects bridging the grid and causing clogs.

• Higher-voltage output for reliable instant kills, even on larger insects.
• Transformer power reduces arc-related shorting and electrical issues.
• Grid design keeps the interior clear so performance stays consistent.

Who this is for: homeowners, small farmers, property managers and outdoor venue operators who need a robust, low-maintenance insect control solution for large yards, wooded lots, barns, patios and decks. If you want a chemical-free, weatherproof unit that combines UV bulbs plus octenol attraction with a powerful shock grid and covers multiple acres, the Flowtron 120W model is built for those heavier-duty outdoor needs.
