Flowtron Outdoor Bug Zapper 1-Acre Protection — 40W UV Lantern with Octenol Attractant and 5600V Grid

The Flowtron outdoor bug zapper is a weatherproof, UL-listed 40W lantern that uses a 5600-volt kill grid plus a slow-release octenol cartridge to protect up to 1 acre from flying pests.

Designed as a low-maintenance alternative to sprays and traps, this Flowtron unit combines a high-intensity UV lamp with a vaporized octenol lure to draw in mosquitoes, flies, moths and other biting insects. The transformer-powered high-voltage grid ensures instant kills while the non-clogging design drops insects away from the unit so it stays effective season after season. Built in the USA with a durable polycarbonate housing, the lantern hangs easily in yards, patios, farms and wooded properties for continuous outdoor comfort.

How does the 2-in-1 attraction system increase bug catch?

The Flowtron zapper pairs a powerful 40W ultraviolet black light with a slow-release octenol cartridge so bugs are targeted by both visual and chemical cues. When the lamp warms the cartridge, octenol vapor mimics the scent of animal breath and attracts more blood-seeking mosquitoes. This layered approach brings higher capture rates across a wider range of species than light-only devices.

• 40-watt UV bulb for strong visual attraction
• 100-hour octenol cartridge included to boost lure
• Octenol vaporization by the lamp reaches more active insects
• Effective against mosquitoes, flies, moths and gnats

What makes the kill grid more reliable than cheaper zappers?

Unlike many competitors, Flowtron uses a transformer-powered 5,600-volt shock grid that delivers a decisive instantaneous kill and resists short-circuiting from larger insects. The grid’s non-clogging geometry causes stunned bugs to fall through rather than jam inside the lantern, preserving performance and reducing cleanup. That higher voltage improves effectiveness across tougher or larger species.

• 5,600-volt transformer-powered grid for instant kills
• Non-clogging design prevents build-up inside the unit
• Fewer short circuits compared with lower-voltage models
• Easy maintenance: occasional bulb and cartridge changes

Is this unit durable and safe for family outdoor spaces?

The Flowtron lantern is UL listed and housed in weatherproof, rustproof polycarbonate built to withstand rain, snow and sun without cracking or fading. Because it eliminates pests electronically, there’s no need for chemical sprays, sticky traps or messy tanks, making it safer around people, pets and wildlife when used as directed. Simple hanging installation means you can place it where it protects living areas without direct contact.

• UL certified and made in the USA for reliable safety standards
• Weatherproof polycarbonate housing resists corrosion and UV fade
• No pesticides—chemical-free electronic control
• Mounts or hangs easily for flexible placement

How large an area will it protect and what upkeep is required?

One Flowtron unit is rated to cover up to one acre in typical yard and wooded settings when hung in a central location. Routine maintenance is minimal: replace the UV bulb periodically and swap the octenol cartridge as it expires to keep attraction high. The fall-through grid design reduces the need for manual emptying and keeps the lantern functioning longer between service intervals.

• Coverage: up to 1 acre, depending on placement and landscape
• Included: 40W UV bulb plus a 100-hour octenol cartridge
• Maintenance: occasional bulb and cartridge replacement
• No messy bags, tanks, or pesticide refills required

Who is this for: The Flowtron 40W outdoor bug zapper is aimed at homeowners, small-scale farmers and anyone who needs continuous, low-effort insect control over yards, patios, decks and wooded properties. It’s a good match when you want an electric, chemical-free solution that’s weatherproof, high-voltage for reliable kills, and simple to install and maintain for season-long protection.
