Say goodbye to pesky flies and biting mosquitoes with the Outdoor Electric Bug Zapper from Flowtron! This supercharged insect Eliminating system puts a powerful dual-action spin on the typical bug zapping lantern with its patented 2-in-1 UV light and octenol attractant, anti-clogging grid, and high voltage transformer that outperforms virtually every competitor on today’s market. Instead of inviting flies inside to collect, crackle, and burn, the powerful 5,600-volt shocker kills them upon contact, sending remains to the ground to be absorbed by the earth. A 40-watt ultraviolet bulb easily attracts biting nuisances from near and far; and with the octenol attractant cartridge, mosquitoes come flying from up to an acre away for TWICE the Eliminating action! This is because our patented design positions the octenol cartridge close to the UV lamp, allowing the liquid to heat up, vaporize, and—in combination with CO2—mimic the breath, body odor, and musk of cattle, deer, sheep, moose, goats, oxen, yak, and other ruminants, which mosquitoes favor. Despite the unit’s shocking efficiency, it still blends seamlessly with your outdoor decor, requires minimal maintenance, and has been rigorously tested and UL certified to withstand the elements for many years of reliable and affordable pest control. For best results, hang approximately 25 feet from your outdoor living space and away from other light sources. Once ideally positioned, plug in and prepare for a bite-free backyard experience!
Cancel the exterminator. It’s Flowtron to the rescue! Welcome home this patented 2-in-1 Electric Bug Zapper—the ultimate solution for ensuring cleaner, safer, more comfortable conditions anywhere you gather in the great outdoors. Position the decorative hanging lantern away from your immediate area, plug in to a standard outlet, and enjoy generous 1-acre protection from buzzing flies, biting mosquitoes, dive-bombing beetles, and other common flying pests. With longer range, higher voltage, and more luring methods than competitors, this 5600-volt model features an intense 40-watt UV bulb for attracting bugs and a patented non-clogging kill grid for zapping them to the ground. Insert an octenol cartridge into the integrated slot, and the powerful attractant is slowly warmed up by the light, resulting in 2X as many bugs eliminated! Each octenol attractant cartridge provides up to 30 days of non-toxic slow-release coverage. And there’s no changing bags, touching carcasses, refilling chemicals, or other costly upkeep necessary. Whether you’re keeping biting bugs away from your garden, backyard, barn, patio, or porch—choose the zapper with the cleanest and greenest Eliminating power! Flowtron handles any flying pest problem like a pro.
Kills Upon Contact: Inferior zappers allow bugs to land, buzz around, make noise, and enter the unit before meeting their ultimate fate. Thanks to its 5,600-volt grid, ours promises instant shock-and-kill action and zero chance of escape.Non-Clogging Design: Nowhere to run, nowhere to fly—and nowhere to gather! Instead of collecting inside a box, our patented vertical grid offers a more hygienic way to catch and kill. Pests simply fall to the ground and absorb back into the earth.Brilliant UV Light: The stronger the light, the stronger the lure! We increased our ultraviolet bulb’s intensity to 40 watts, making it suitable for small-to-medium sized backyards as well as sprawling properties up to a maximum 1 acre range. Octenol Partridges: Our electronic zapper is highly effective on its own, but for mosquito-infected areas, using additional lure makes it even more powerful! The octenol cartridge slowly releases attractant for 30 days and is USDA approved.Safe for People & Pets: With your zapper hanging high up and 25 feet away from your immediate living space, there’s no threat to children, dogs, livestock, or plants. Chemical-Free operation is also friendly to local flora and fauna.Kill More, Save More: This bug killer operates for pennies a day, making it the most economical choice for securing a bite-free zone for your family. Octenol mosquito cartridge replacements are also very affordable—shop the Flowtron Amazon store!Safety tested and approved: Flowtron Bug Zappers and other pest control accessories are proudly made in the USA, manufactured with the most durable materials, and always 3rd-party tested and approved for safety and quality.

Customers say
Customers find the bug zapper effective at killing mosquitoes and appreciate its functionality. The build quality and value for money receive mixed feedback – while some say it’s well-made and worth the price, others report receiving broken units and consider it a waste of money. The noise level and brightness also get mixed reviews, with some enjoying the satisfying zap sound while others find it noisy, and while the light is bright, it’s not very visible during the day.

LOVE IT
This thing is incredible!!! We have the dangerous breed of mosquitoes (white bands/spots) invading our property. It’s so bad, we haven’t been able to even get to our vehicles without being swarmed. They are everywhere. We have no standing water on our property, but there’s a creek half a block away.I didn’t want to have to keep using chemical bug sprays on our skin and lawn sprays that could affect our dogs. I understand bug zappers sometimes kill beneficial insects too, and I’m sorry about that… But this thing is incredible!!! I set it up last night and there’s a huge difference today. I can walk around in my yard without seeing a mosquito at all!I used a shepherd’s hook (Walmart) to hang it about 30 feet from my house. Our lot is just over an acre. I used a 25ft medium duty outdoor extension cord to plug it in to my garage. We plan to keep it running 24/7 for the summer and replace the mosquito attractant once a month. Do not mount this thing near your house, follow the directions. The mosquitoes do swarm the area around the zapper because they are attracted to it. This would be dangerous if you have little kids, you would want a taller shepherds hook. The one I have mine mounted on is 48 inches.

Great bug zapper
Bug zapper works great. This year was a bad bug year. I plug it in at dusk by dawn the screen is packed with dead bugs. I just blow dry them off & do it again the next day. It has made a significant difference with the amount of bugs I have in the yard. Before I purchased this, the mosquitoes would attack you immediately. Now I have an occasional bug bite. The only draw back on this zapper is having to blow off the dead bugs daily. The birds sit under the light and eat all the bugs blow off afterwards.
J. Boyd –
it works well the moment it is plugged in. Strongly recommended.
No wonder this bug zapper has a high rating – it just plain works! The construction is strong, the performance is awesome, and the price is reasonable. It began zapping mosquitos, flies, and gnats immediately after being plugged in. The 40 Wt bulb is bright, but not excessively so. Neighbors should not find it objectionable. We didn’t install the bug attractant, choosing to see how well it worked just with the blacklight. A couple of minutes after plugging the unit in we were zapping 1-3 bugs per second. So it works, and has continued to work nightly for the two months since we purchased it. We find it superior in construction to what we saw at HD. Hopefully it will last for more than one season.

These work great! (Just aren’t clog-free)
These zappers work great. I actually bought 2 for my house, front & back. BUT they are not clog-free. Every night it kills hundreds of bugs. Every morning I have to go & clear it out so it’s unclogged the next night for the bugs to get zapped/ electrocuted.I actually bought a little handheld rechargeable blower to blow the bugs off- like a can of air, but a machine, not a can. I had tried a little brush but that was difficult, time-consuming & gross. The little blower works great.The mosquitos still swarm my doorways, though, even though the zapper is 25 ft away from my door as directed. So I’m gonna try the DUNKS to put in standing water. The have a bacteria that disrupts the life cycle of mosquitos to where they die before they get big enough to bite. The water is still safe for everyone.
Juan Allievi –
It actually works!
Must admit I was skeptical. I bought it because wth it is inexpensive and I wanted to try if it would do anything.I installed it near my patio dining table, I guess not following the instructions that indicate it should be far from people.I was very much surprised by the result, I can be outside without wearing any repellant! In the past I’d get bitten to the point of desperation.Towards midnight, when humidity is higher, I do get some mosquitos in my ankles, but then I just wear a little repellant and that’s it.I still need to move it away from my table and see if it makes a difference.

Works great best shock bar that I’ve had strong metal
This is the best bug light on the market cost a little more but it’s worth it . I bought 3 of them 2 of the 1 acre and 1 of the 2 acre I like to here them sap the bugs with the noise they do that I use my leaf blower to clean them out every now and then most of them fall through. The metal on the kill bar is solid and not screen wire.
Clayton Miller –
Usa quality made!
This is by far the best bug zapper ive used. It covers a large area and when the bigger bugs get on the coils it takes them out. It is very powerful and bright. It seems to be made with quality components, and a thick plastic cage. We keep ours in our travel trailer, its very nice to have if we end up in a spot with a lot of bugs.
Tony –
Great over the years
Zaps and kills everything. Had it for 4 years now and it runs great every summer. I live next to the wetlands. It kills a ton of bugs nightly and has lasted longer than the Black Flag ones that I used to buy. I run one in my front yard and one in back. When the screens get “full”, I just hose them down with the garden hose or flush out the screen with my backpack blower.
Amazon Customer –
Item is used, has dead bugs on it. Item also doesn’t switch on.
racedogs –
This is a reasonably priced very efficient bug zapper. I purchased it specifically to help deal with a very large mosquito population that prevented us from sitting outside any time of day. This unit is quite strong, reportedly covering 1 acre, which I have. The unit is well made and works great. I hung it on a plant shepherd hook about 6 feet off the ground. It comes with one Octenol cartridge which does a nice job of attracting mosquitoes to the zapper.I would highly recommend purchasing extra cartridges immediately as they should be changed monthly to be effective. Debris in the unit is easily cleaned using a can of compressed air that will last for years.

Does not work
GRAHAM P. –
This product is not suitable for UK 240 volts, which it does not say in the product information. And despite being sold at a UK £ Price.The product is also poor quality being made primarily of cheap plastic.Although the suppliers ‘Covent Garden’ who it turns out are a US company promptly repaid only the purchase price when I complained and returned the product it still cost me £45.38 in postage.Avoid this product if you are in the UK and want to use with UK voltage.
Matt Webb –
DO NOT buy this product if you live in the U.K.! Supplier sent 120V unit instead of 240V. Only after having an electrician attempt to install it (as it does not come with a U.K. plug) was it realised that it was incorrect. The supplier refused to return the item as too much time has passed (as I had to wait for an electrician). Item description should have been clearer and refund should have been offered.
