Quick verdict
A 40 watt UV and octenol lure electric bug zapper from Flowtron, rated for up to 1 acre and built around a 5600 volt kill grid that drops insects to the ground on contact, with a 100 hour octenol cartridge included to boost the mosquito specific kill rate. It suits a yard, patio or farm that wants a visible, immediate kill rather than a passive trap. The caveat that applies to every electric grid zapper, including this one, is that the grid also kills large numbers of harmless and beneficial insects along with the mosquitoes it targets.
Strengths
- 40 watt UV light combined with an octenol lure, which the maker says increases mosquito kill rate over UV only zappers
- 5600 volt grid kills on contact, no collection needed since insects fall to the ground
- 100 hour octenol cartridge included in the box
- Weatherproof polycarbonate housing, UL listed
- No sprays, fogs or sticky strips to apply or clean up
Weaknesses
- Electric grid zappers kill a wide range of insects drawn to the UV light, not only mosquitoes, so many harmless and beneficial species are caught along with the targeted pests, a long-documented drawback of this whole product category
- Octenol cartridges and the UV bulb are ongoing consumables, and the listing does not state a replacement cost
- Needs a standard outdoor outlet, so placement is limited by cord reach rather than being fully portable
- The 5600 volt grid produces an audible snap on every kill, which is noticeable close to a patio or bedroom window
The overall YardToolLab Score is out of 100. Section scores are out of 10.
Who this zapper is for
Some households want proof a mosquito control device is working: a visible light, an audible snap, insects on the ground by morning. The Flowtron electric bug zapper is built for that preference, pairing a 40 watt UV light with an octenol scent lure and a 5600 volt kill grid, rated for up to 1 acre of yard, patio or farm. It suits anyone who wants an immediate, visible kill rather than a passive trap that needs its basket checked to know it is working.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The listing states a 40 watt UV black light, an octenol attractant cartridge rated for about 100 hours and included in the box, a 5600 volt non-clogging shock grid, coverage up to 1 acre, a weatherproof polycarbonate housing that is UL listed, and a standard plug for any outdoor outlet. Flowtron states insects fall to the ground after being killed and are left to break down naturally rather than needing to be collected. Not stated: the unit’s dimensions, weight or exactly how long the UV bulb is expected to last before replacement.
Light, lure and the kill grid
This is a true electric grid zapper, not a fan trap like a DynaTrap unit: insects are drawn toward the UV light and the warmed octenol cartridge, then killed on contact with the charged grid, producing the audible snap that gives this style of device its name. Octenol is the detail that sets this Flowtron apart from a plain UV-only zapper. The cartridge vaporizes under the lamp’s heat and mimics the scent of an animal’s breath and body odor, the cue mosquitoes track above almost anything else, and Flowtron states this meaningfully increases the mosquito specific kill count compared to light alone.
Coverage and placement
A 1 acre rating puts this zapper at the larger end of homeowner models, suited to a farm, a big backyard or a property with standing water nearby that breeds mosquitoes faster than a small unit can keep up with. As with any zapper, placement away from the areas people actually sit is worth considering, since the light and lure draw insects toward the device from a distance, and a unit mounted right next to a dinner table pulls activity through the gathering space on the way in.
The zapper trade-off
Every electric grid zapper, Flowtron included, works by attracting flying insects to a light and killing whatever reaches the grid, and that is not selective for mosquitoes. A wide range of moths, beetles, and other nocturnal insects, many of them harmless or even beneficial pollinators, are commonly caught on the grid right along with the mosquitoes, flies and gnats the device is sold to control. This is a long-documented limitation of grid style zappers as a category, and the octenol lure here helps bias the catch toward biting insects without eliminating the broader kill. Anyone who weighs insect impact heavily should know this before buying any grid zapper, not only this one.
Living with it
Keep a spare bulb and octenol cartridge on hand for peak season, since both are consumables and the listing does not give exact lifespans for either. Wipe down the weatherproof housing occasionally, and let insects fall and break down naturally as the maker describes rather than trying to collect them. Mount it where pets and children will not brush against the grid, and expect the audible snap to be noticeable on a quiet patio.
Alternatives to Consider
A DynaTrap fan trap such as the DT1130SR or DT2030-GRSR pulls insects into an enclosed basket instead of an exposed grid, trading the visible kill for less impact on harmless insects. The GOOTOP electric zapper is a smaller, lower voltage grid zapper for a half acre yard at a lower price, without an octenol lure. For a single patio rather than a full acre, a propane or citronella based repellent avoids an electrical trap entirely.
Verdict
Buy the Flowtron 1 acre electric bug zapper if the property is large, you want a visible and immediate kill backed by an octenol lure, and you accept that a grid zapper will also take out some harmless insects along with the mosquitoes. Skip it if minimizing harm to moths, beetles and other non-target insects matters more than a visible kill, where a fan trap like DynaTrap is the better fit.

Flowtron Electric Bug Zapper, 1 Acre Outdoor Coverage, 40W UV Light, 5600V Grid, Black FAQs
Flowtron states that the octenol cartridge vaporizes when warmed by the UV lamp and mimics the breath and body odor of animals mosquitoes track, which the maker says significantly increases kill count compared to UV only zappers. Octenol is a well established mosquito attractant used across several zapper and trap brands, so the mechanism itself is not unique to Flowtron.
No. Electric grid zappers attract insects with UV light, and a wide range of flying insects are drawn to that light regardless of whether they bite. Moths, beetles and many other harmless or beneficial species are commonly caught on the grid along with mosquitoes, flies and gnats, which is a well known limitation of grid style zappers in general, not just this model.
Flowtron rates the octenol cartridge at about 100 hours and says to replace the bulb when it burns out, without giving a fixed bulb lifespan. Treat both as seasonal consumables and keep spares on hand during peak mosquito months.
The maker states the unit is safe for use around children, pets and wildlife with no additional sprays or treatments required. The usual precaution with any high voltage grid zapper still applies: keep curious hands and paws from reaching into the grid itself, and mount it where people do not brush against it.
