Flowtron Electronic Insect Killer Reviews – What is The Effective Way?

Insects like mosquitoes and bugs are always annoying to us. Even though you live in a busy city or in a peaceful village, bugs and insects are still there. When it is warmer and more humid, especially in summer, these unwanted guests are harder to control.

You want to enjoy a lot of activities in your garden but end up with itchy bites and rashes. Have you paid so much effort in repelling these irritating insects in vain? Do insect sprays, bug traps, electric fly swatter, or citronella candles work?

If not, you might consider a new method: bug zapper. The Flowtron Electronic Insect Killer is an excellent choice of the advanced electronic zapper.

It contains a bulb that emits bright ultraviolet light to attracts insects and draws them near to the unit, then an electric shock kills them. That is how it works.

Here is our Flowtron Electronic Insect Killer review with some of the highly-rated products from this brand. We hope you can find a suitable one and succeed in repelling these nasties.

The Flowtron BK-15D Electronic Insect Killer is a top-rated and useful product that works effectively across a radius of ½ an acre. So, if you have a small to medium-sized garden or yard, this might be the thing you need.

The product is designed as a black lantern with powerful features. The highly intense ultraviolet light from the bulb attract insects to go through the cage. Then, they will be trapped on the killing grid with a high voltage transformer.

Do not worry about harming the surrounding environment. This UV insect killer is an environmentally friendly product, making it a safe way to repel flies, bugs, and other vermins.

With this product, you can use a USDA-tested Octenol, an insect attractant. You can buy this attractant separately.

An outstanding feature of this electric killer is the non-clogging trapping grid.

If you have already used other insect zappers before, you can see the filters accumulating debris, dirt, and of course, dead insects - and it is gross! Cleaning it is another challenge. It can also be dangerous, causing short-circuiting and combustion because the insects still stuck there.

Luckily, the grid of Flowtron BK-15D Electronic Insect Killer will blow your worries away. Basically, it kills the bugs without making them clog. It also helps to prevent potential short-circuiting because of insect remains.

Of course, there are some shortcomings, like the too short chord. To use the product, an extension is necessary. And the machine is not smart enough to distinguish between beneficial bugs needed for plant pollination and harmful pests.

To take advantage of the Flowtron BK-15D Electronic Insect Killer, put it in the place where you see the highest concentration of insects regularly. You do not need to think of how to trick them into flying to the machine - they still come anyway. Hang it at 4 - 6 feet from the ground and let the machine do its work.

Remember not to use it within the area of 25 feet used for human activity. You should not attach it to your deck or house, either. And the cartridge should be replaced every 30 days.


  • Affordable
  • Environmentally friendly
  • Weatherproof polycarbonate construction
  • Effective insect-killing power
  • Unique non-clogging trapping grid
  • Easy bulb replacement
  • Minimal noise


  • Short cord
  • Cannot distinguish between beneficial and harmful bugs
  • Bulb’s short life

Overall, the Flowtron BK-15D is one of the best models. It has a great design and offers a lot of benefits to users.

This Flowtron BK-40D Electronic Insect Killer can cover a larger radius than the Flowtron BK-15D above - up to one acre. 

Once warmed up, it will become a killing machine! The 40-watt bulb emitting high-intensity ultraviolet light and the powered Vertical Rod killing grid system are carefully tested to bring high performance.

It takes about half an hour for the bugs to find the light attractive. In two hours, this machine can kill dozens of mosquitoes and other flying insects.

One more thing is that the lightbulb in this unit may be too bright for sensitive eyes, especially in the dark. So, do not stare directly at it.

The device is made of robust and weatherproof polycarbonate construction so that it will not crack, rust, or fade over time.

When it comes to safety, the exterior polycarbonate grid has small gaps. They are big enough for bugs to go through but too small to your hands and noses.

You should hang the lantern at an appropriate height so that it will be out of children’s reach. Hanging the Flowtron BK-40D Electronic Insect Killer also gives it a 360-degree view and helps it work best.

Remember, this device is for outdoor use only. Do not attach it near your house or the place with a lot of people. We think it just attracts annoying bugs closer to the house, and you have to hear continuous zapping noise! Then the dead insects on the ground may attract more ants to come.

Once again, the Flowtron machine is non-toxic. So, you can completely be assured that this is an environmentally friendly way to get rid of mosquitos, flies, and biting insects from your living area.

Like the BK-15D, this model has a non-clogging killing grid and an open bottom design so that burnt insects will fall to the ground. It is like self-cleaning and requires no special maintenance.

However, if it still gets clogged, you can clean it by using compressed air to remove the stuck bugs. Or, if you want to use a garden hose, unplug the zapper and then spray water over the bulb and grid. Do not get water in the upper box because the high voltage transformer is located there.

If you see bugs sticking to the light, just use a brush to wipe them away.

The product also includes a cartridge containing Octenol, an insect attractant, but you can use it or not; it is okay. If you want to use it, attach it to the bottom of the unit.


  • Environmentally friendly
  • Energy saving
  • Larger killing zone
  • Effective
  • Can be used with or without the chemical attractant


  • High price
  • Too bright bulb
  • Must arrange a hook system to hang the device

If you have a smaller yard, you may want to buy a bug zapper with less coverage to save money. But if your area is large, this bug zapper is worth your investment.

The Flowtron BK-80D 80-Watt Electronic Insect Killer is the last product we want to introduce.

Designed as a beautifully decorated lantern, this insect killer will eliminate detestable flies and bugs but also embellish your yard or porch.

This product uses a material resistant to rust so that you can leave it outside in the rain without worrying about anything. It actually does great in that condition. Meanwhile, many other products on the market do not feature weatherproof and durable material like this.

The device uses two 40-watt "U" shaped bulbs BF-150 producing high-intensity ultraviolet light for larger lure capacity. Many users agree that this 80-watt version is the most powerful of the three models.

Another nice benefit is that the bulbs can last for a long time. The product is already energy efficient so that you can use this bulb for up to one year.

For better effect, you can use the USDA-tested Octenol mosquito attractant cartridge (6 packs). It will be activated when you turn on the unit.

In addition, this device has all the features that are already on the two models above. For example, there is no toxic chemical, non-clogging killing grid, weatherproof polycarbonate construction, and easy bulb replacement.

If you have dogs and cats, then you have to face one drawback - the electronic insect killers can frighten or annoy your pets. If they can get used to the device, you should keep the zapper some feet away from your yard.

And again, the too-short power cord is a common problem of the Flowtron zappers. The length of 8 inches is not enough to do anything! You will need an extension cord to use it.


  • Environmentally friendly
  • Energy efficient
  • Most powerful
  • Bulbs’ long life
  • Easy bulb replacement


  • Frighten cats and dogs
  • Short power cord

The Flowtron BK-80D 80-Watt Electronic Insect Killer operates only for pennies a day but helps you to avoid the lasting expense and consequence of toxic chemicals.

Why Should You Invest In The Flowtron Electronic Insect Killer?

You must have heard of Flowtron, a division of the Armatron International. It has produced electronic insect killers and other outdoor devices for half a century and become globally prestigious. And you already know how this kind of zapper works - the way it lures and kills insects is so effective.

What other benefits do the Flowtron Electronic Insect Killer bring you?

Ease of Use

Unlike many other pest control methods, every insect zappers of Flowtron is pretty easy to use. Many mechanisms enquire complicated preparation, assembly, or installation.

But with this device, everything becomes easier. However, the power cord is too short so that you will need an extension. After you plug it in, it will work uninterruptedly.

You do not need special maintenance, either. You can easily spray the bulb with a hose or use compressed air to prevent your device from becoming clogged. The grid can automatically turn off if it is too clogged to avert overheating.

High-quality material

Another outstanding feature of the Flowtron Electronic Insect Killer is the rugged and weatherproof material, which is resistant to rust, crack, or fade.

That also means the longevity of the device will be higher. If you maintain the product well, you can use it after some seasons without repurchasing.


We know some insect-resistant products may require you to use chemicals on your skin or spray chemicals in the air. But everything is different with the Flowtron Electronic Insect Killer.

It effectively kills mosquitoes, flies, and bugs by using high voltage instead of spraying chemicals. It is also friendly to your living environment.

Although it is safe, you must follow the manufacturer’s instructions strictly. For example, do not place the zapper right next to your house or the place of human activities; otherwise, it will attract more insects to come.

Quick Insect Killing

Some traditional methods can be so slow acting. They may take from several hours to days to be fully active. In contrast, the Flowtron zappers can kill them immediately once in touch with them.

After the first night of use, go to your garden and check - there would be many dead mosquitoes!


We have to say that the Flowtron Electronic Insect Killer works great - it is incredibly excellent at killing mosquitoes and other flying insects. The high-intensity ultraviolet light from the bulb really attracts insects toward it without using any toxic chemicals.

When you plug it in, you do need to worry about the power stopping while you are sleeping or replacing the bulb regularly. As a whole, it will give you maintenance-free operation and high performance.

How To Select The Right Insect Zapper?

This instruction is applied not only with Flowtron Electronic Insect Killer but also with other kinds of bug zappers. Cause you know, there is a variety of bug zappers available. Some are powered by electricity, like Flowtron devices. Some use a magnetic, battery, or solar power.

Indoor or Outdoor Use

Consider whether you need to kill mosquitos and flying bugs inside or outside your house. Some models are for outdoor use only, especially the ones that produce a harsh chemical.

However, some models can be used both indoor and outdoor.


Is your choice of zapper safe to yourself, children, pets, and the surrounding environment? Or does it use harmful chemicals and emit a bad odor?

You should select non-toxic methods, which still do a great job without dangerous pesticides or baits. The device with a high-density ultraviolet light bulb is a great idea.


Do you consider the size before buying an insect zapper? You should check the product specification carefully to choose the one that suits the size of your yard, garden, or the place you intend to place the device.

Like, some models are advertised to work efficiently in a radius up to one acre. But if you want to cover a much larger area, you may consider having more than one.


Some models require you to clean it often while some do not. Just remember not to let the tray to be full of dead insects.


Check the specifications carefully to know whether your zapper is weatherproof and waterproof or not. And of course, if you choose a device for outdoor use, it should be waterproof.

So, Make A Choice!

We have already shown you the three outstanding models of Flowtron.

Our favorite choice is the Flowtron BK-15D Electronic Insect Killer. You do not need to pay too much money to have it. Although it is a small device, it is useful in killing annoying insect guests and can cover a medium-sized garden.

It is also an innovative method to capture and kill insects - using high voltage. So, you can rest assured it is safe for you and the environment during use.

We also prefer the BK-15D to the BK-40D because it seems more versatile and economical. However, if your place is more extensive, you can go with the BK-40D model. For a better result, you can also buy the attractant bundle to use with it.

So you see, this brand has unceasingly designed devices that effectively repel unwanted and harmful insects from outdoor areas.
