Game Changer
Color: Midnight Black
This product is the BOSS of zappers. I live in Mosquito-land Orlando FL and have been going through 2 cans of spray per month from April through October just to go out and work in my gardens, and was still getting bit up. I bought this zapper and leave it on from sundown to sunrise and poof-problem resolved. I rarely need spray now and all the red bite marks I grew accustomed to having are gone. When I first turn it on in the evenings, the first 10 minutes are pretty active as anything with wings heads straight for it. Then it's relatively quiet throughout the evening. When the termites came down from the oak trees this past summer, they went straight to it. The lizards are asleep overnight then in the morning after the light is off, they feast on the "bbq'd" bugs all over the ground then crawl all over the metal grill in the light and strip it clean. They know to be gone by a certain time but there have been just one or two that didn't get out in time. I'm going to buy another one for my front patio/courtyard to keep mosquitoes away from the front door. They hang out on the glass because its illuminated from the indoor lighting. They inevitably get in when the doors are opened and closed but another light should resolve that as well. Used the pack of mosquito bait included and haven't reordered, doesnt seem necessary in my situation. I've gone through a few smaller zappers I bought at Lowes and the bulbs went bad very quickly. I think this bulb is replaceable where they were not. Guess I'll cross that bridge when the time comes, but there's no doubt this zapper is by far superior and really delivers. Made in USA made it ALL THE BETTER.

Simple and clean (no fly swatter splats) way to fight pesky flying insects but not so much female biting mosquitoes
Color: Midnight Black
With cases of West Nile Virus and other mosquito-transmitted viruses such as Chikungunya (87 confirmed travel-associated cases in Florida in 2014, as of July 19.) cropping up in the U.S. and our area, I was proactive in helping when visiting my daughter in rural Baltimore, MD and encountering alot of flying insects. My daughter has a huge, covered back porch that runs the length of the house and a smaller one in front. There is a lot of foliage surrounding the house and bugs, particularly biting ones, tend to be bothersome. The porch is not screened in, so I bought bug zapper to see if it would help and it does! We had used one years ago at our cabin in New Hampshire which was also surrounding by trees and foliage and mosquitoes were a particular problem since the region used to be a swamp. It seemed to be working since we could hear the zap sounds of insect victims. My daughter says that bugs seem to be a lot less prolific. Indeed, light-seeking insects, and other flying ones that happen to fly in its path) will be killed by this zapper (moths, et al). Still, zappers tend to be ineffective in killing biting mosquitoes even though other insects will be killed by the score. Bug zappers attract insects using ultraviolet light and the low voltage current surrounding the mesh cage kills the insects that attempt to reach the light. The problem is that mosquitoes are not attracted to light; rather, they seek out carbon dioxide to locate blood proteins which are used to develop eggs, so only female mosquitoes need to draw blood and bite. Some mosquitoes prefer bird, snake, or frog/toad blood and others like plant nectar. A few don't even need blood to hatch eggs. Along with CO2, perfume, sweat, and body odor also can attract mosquitoes. Hence, the substance that comes with the bug zapper designed to attract female, biting mosquitoes. So, we heard tons of bugs being zapped at our cabin in NH and numerous studies have shown that bug zappers are rather ineffective at killing female mosquitoes. What bugs were being killed then? One 1997 study (1) determined that the mosquitoes found in zapper collection trays were non biting midges (look like mosquitoes) that are attracted to light. I also recall giving my daughter a DEET-based product to spray the area surrounding the house to repel mosquitoes. Perhaps she used that in addition to the zapper and that is why she has noticed a difference. Using DEET products and eliminating breeding habitats like standing water (e.g., after it rains) will help to reduce mosquito populations. Wearing protective clothing is also a deterrent. I provided more detailed information about mosquitoes since the mosquito-borne virus threat is serious and a current menace and I thought that people should not rely on this zapper to protect them from it. Anyway, I have no complaints about this bug zapper and recommend it for reducing flying insect nuisances - just not for effectively combating female biting mosquitoes. (1) Snap! Crackle! Pop!

Great Zapper! Really cooks ‘em

Great zapper, fair price. Kills bugs all night and the birds eat the fried bugs in the morning. Circle of life! Easy to clean, insects flock to it and it is very effective. Highly recommend.

15 watt Flowtron vs 40 watt model
Color: Midnight Black
Recieved this device (15 watt Flowtron), along with the spare bulb I purchased, and plugged it in 30 minutes ago about eight feet from my favorite couch. It has already zapped well over a dozen bugs. Instead of using chemicals as I have in the past, sought a better way to rid my home interior of bugs. The noise is minimal. Like one reviewer said: the cord is short- real short. Less than a foot. It's working beautifully. Now, just need to replace my roach baits and I'll be ready for the summer bug season here in my sub tropical, coastal, bug infested location. Will likely need to fabricate a tray device to catch dead bugs as they fall. Think I'm gonna like this thing. Update: It has now been five days since I received my 15 watt Flowtron bug zapper and I'm happy with it. It has been on 24/7 since I plugged it in. It's not terribly bright which makes for a soft night light for my den. As I kicked back with my laptop tonight and listened to a bug fry every now and then, just ordered two more 40 watt Flowtron units. Hope to have a very bug free summer in my home. Be advised that these things do not discriminate between benificial bugs that we need for pollination of plants and such. Therefore, there is valid scientific criticism regarding their indiscriminate outdoor useage. Any bug inside my home is fair game. It did not zap every last bug but it has put a big dent in my bug population. My cats don't quite know what to think of it yet. Update #2: Before buying my first Flowtron, sought information to help me decide what size unit to buy. Have now tried out a 40 watt model in my home. It works well, is significantly larger than my 15 watt unit and the transformer hum is a little bit louder. The bulb in the 40 watt Flotron cost twice as much to replace. Leave the 15 watt unit on 24/7 inside. It works well and uses less power. The 40 watt units are brighter and would be my choice for serious outdoor useage. Will use both of the 40 watt units if needed and turn them off when I go indoors. Inside, just can't see much advantage of using the larger 40 watt unit size. Now, leave my door open longer when going to and fro knowing the 15 watt bug zapper is always at work inside. It's popping a bug every few minutes or so tonight. Should be able to use significantly less insecticide in my home now. They do not zap every bug but work quite well. Only notice the 15 watt model eight feet from me when a bug gets zapped. Flowtron seems to make a solid, well thought out American made bug zapper and stand behind them. June 25 2009: My 15 watt bug zapper has been on nonstop since I first plugged it in over a month ago. It has been frying bugs in my house day and night trouble free. Have not cleaned it yet. One of my cats runs and hides sometime when a big bug makes more noise than usual. If and when this one quits, will get another 15 watt model for my home interior. It does not zap them all but sure helps a lot. July 29 2009: A house fly was bugging me bad in my home the night before last. Knew that if I was patient, the annoying little bug would find his way to my 15 watt flowtron at some point just like many before him. Sure enough, as I went to sleep, he fried- well done. Have used very little insecticide this summer in my home with this thing working 24/7 nonstop and consuming only 15 watts of electricity. Wish I had thought of using one of these things sooner. My jumpy male cat has gotten more use to it now. Would go with a 40 or 80 watt model for heavy duty outdoor use at night. The 15 watt size is perfect for my indoor purposes. Still haven't cleaned it. It's right trouble free. There is a bit of an odor when a house fly or large bug gets zapped. That's no problem relative to getting rid of the bugs. April 8, 2010 : Since this makes a good night light, left it on all winter. Have not turned it off since I first plugged it in. It just zapped one of those large, lanky, mosquito looking type bugs. Was wondering how long it would take for him to get fried (about an hour since I first saw him). Have not needed the spare 15 watt bulb yet. With ten boxes of fresh new roach baits, am ready for bug season again. May mount one of my 40 watt Flowtron units inside this Summer if needed. August 6, 2010: It's time to deal with hurricanes, bugs and heat now. My trusty 15 watt Flowtron is busy tonight for I have little nats and other flying bugs in my house. That same 15 watt unit has been on nonstop since I first plugged it in- same bulb with no problems. Just needs some cleaning up now and then. At less than $30 currently with shipping, think I'll buy another 15 watt unit to put in the other end of my home. Need to step up my roach battle also. Have four tubes of roach gel. It's impossible to keep them out around here. Like living near the ocean even with the bugs. Before I got this device, used insecticide (flying insect killer) every second or third day during the tropical season. Now, have not gassed my whole house like I use to do yet this summer. Surely that is healthier than the chemicals I used before. It keeps the bugs under control- they don't bother me with this device in service 24/7. Just use common sense if you intend to use it indoors. Keep it away from all flammable things. It's an electrical device that'll have dead bugs falling from it. It is always possible that the device can catch on fire. So use good sense and understand the potential hazards it can present wherever you use it. Have mine on power strips such that I can easily switch them off when I leave the house if I wish to do so. May 10, 2011: Ordered two 18" round pizza pans to suspend below my indoor units in order to catch most of the zapped bugs as they fall. Some black coat hanger wire and a drill should do the trick. Have not had my bug zappers on yet and I can really tell the difference inside already. Bought six cans of Raid insecticide for the summer. A roach actually bit me on my right arm tonight. He's high on Raid now. Wish I could find something like this Flowtron device to help zap the big roaches as they somehow find a way inside. It takes time for them to find the roach baits that are all over the home where food and water are available. There's no way to keep them out around here. April 15, 2012: Have had one of my 40 watt bug zappers on indoors for a week now as Summer approaches. These were money well spent for me. A screw in Levitron socket to outlet adapter available from Amazon or a hardware store will allow one to plug these units into a standard light bulb socket on an overhead light fixture or wherever. There is something sadistically satisfying about hearing a bug get fried now and then as I write this :) 2013: Harris boric acid tablets have got to be the best thing I've ever used on roaches. Put them out last Summer and in 30 days, no more roaches. They eat them like candy. Simple, safe/natural and cheap. No hazardous chemicals.

Kills bugs when it’s dark out, not in the evening when you are out.
Color: Midnight Black
During the evening when it is dusk, it’s almost completely ineffective. I almost don’t hear a single bug getting zapped the entire time period, while the mosquitos flock around me, even if I’m sitting close to the unit. Once it gets dark outside, bugs that love the light flock to it and it does a good job then. I bought it primarily for mosquitoes, though, and it doesn’t seem to make much of a difference there at all.

I bought this 11 years ago, and it has worked perfectly ever since. I run it a every summer, and the bulb just now needed to be replaced. It's easy to take apart and clean. I've used it on flies in my garage, mosquitoes and moths outside. It killed an entire yellow jacket nest that had made its home under my house in the crawl space. Took a few days, but it got every one of them.

Mosquito Destruction! (FAIL)
Color: Midnight Black
UPDATED AUG 17, 2020: DO NOT BUY. Changed from 5 stars to 1 star. After many years, my bulb failed, and I ordered another unit. The product now has a more "clear" bulb vs the blacklight style bulb of the former unit and doesn't attract bugs the same way. Or at all really. Returning. It's sad when a company has a really great product and then ruins it because of a slight change. I don't know how long this product had been changed with my former review up. FORMER REVIEW June 23, 2015: We live between a swamp and two ponds in a heavily wooded area, therefore we are always waging war on mosquitoes. This spring we placed a propane powered mosquito vac in our yard, and had to clean it every day, because the basket will fill to the point where it would loose suction and stop sucking mosquitoes. And while it did collect at least a few hundred mosquitoes a day, it would loose suction from all the bugs and the cottonwood tree fluff. So we placed this Flowtron (1/2 acre) bug zapper unit within 5 feet of the propane powered vac in hopes that it would take some of the load off of the mosquito vac. I would have been happy if the bug zapper got even half as many mosquitoes as the mosquito vac, but that was not the case! What we found was that this zapper kills at least 1000 times more mosquitoes than the propane unit!! IT'S INCREDIBLE! I included a picture of what the unit looks like in the morning after hosing it completely out. THOUSANDS of little buggers! There were maybe a few dozen bugs that weren't mosquitoes, all the rest were mosquitoes. I wouldn't expect this type of performance with just the stand alone bug zapper, I think it is due to the combination of the propane mosquito vac luring them in, that that's right beside the bug zapper. However, this mosquito carnage comes with a downside. Now we have to clean this unit out every day as well! The grid simply becomes so solid with fried mosquitoes it blocks all light from the bulb! We simply unplug, hose out with a light spray of water, and dry by setting it on our central air condenser unit for 30 min or so (gentle blast of warm air!). So 5 stars for inflicting massive damage to the mosquito population, (thousands per day!) 4.8 stars for needing to clean it out every day. I can't give 4.9 stars, .so 5 it is! WARNING: Do not hang this unit over a deck, or near anything that could burn as it will occasionally rain flaming (as in on fire!) bug debris! Seriously, there should be a warning sticker on it. FLAMING BUGS WILL FALL FROM THIS UNIT. I would not be surprised if the whole bug zapper just burst in to flames some night. (and I wouldn't at all be disappointed! DEATH TO MOSQUITOES!) We've decided to order another Flowtron, the larger 1 and 1/2 acre unit as well to hopefully better handle the mosquito load. We hang this in our yard, at the end of a 50 foot extension cord -it only has a 6 inch cord, you will need an extension cord!- on a shepherd's hook. I would never recommend hanging this on, or near anything that you weren't ready to burn to the ground. Update July 1, 2015: The 1 and 1/2 acre flowtron was a complete failure at killing mosquitoes. It didn't even really hardly kill any bugs at all! The bulb on the smaller 1/2 acre unit is like a black-light. Deep purple, not very bright. Lures in bugs like crazy. The bulb on the 1 and 1/2 acre unit is blue and super bright. Light up the whole back yard bright, including the neighbor's house bright! Crazy bright! I'm not sure if the color is wrong to attract bugs, but it actually seemed to repel them away from the mosquito vac! I'm not sure what I'll do with the 1 and 1/2 acre unit with the super bright bulb. I would never buy it again, and recommend people steer clear from it. Go with the 1/2 acre unit, it's wonderful.
