See, the presence of bugs, such as flies, moths, mosquitoes, and other pesky insects, causes a lot of discomfort ultimately making your life miserable.

Mosquitoes, in particular, are nerve-wracking due to their annoying buzzy sounds and itchy bites.

Bug zappers, also known as fly zappers, light bulbs, fly traps, or camping lanterns, offer an effective, safe and affordable way to eliminate the bloody insect around.

Typically, bug zappers take advantage of the insect's natural attraction to light and then use electrocution or dehydration to kill the tiny creatures. They offer one of the most unique and efficient ways of eliminating bugs.

But, just like with anything else, there’re plenty of bug zappers out there. And so, choosing the right zapper for your needs might feel a bit intimidating.

Flowtron BK-40D

Flowtron BK-40D is the real outdoor insect magnet with wide coverage.

With long-range coverage of up to 1 acre, it’s perhaps the ideal bug zapper for your large yard.

It's quite a performer, too, and using a combination of light and electrocution technology; this zapper is capable of eliminating the annoying flying insects and other bugs effortlessly.

Flowtron BK-40D

Features and Benefits

Design Quality

Flowtron BK-40D features a basic design, yet it complements your existing lighting system.

It’s a weatherproof option, too, with the polycarbonate lantern house preventing the zapper from fading, cracking or rusting.

While the material construction serves the durability purpose, it also translates to better aesthetics.

Many of the users reported using Flowtron BK-40D for several seasons without the zapper breaking down.

Flowtron BK-40D is undoubtedly built to last and withstand typical weather.


Flowtron BK-40D is available in a tapered lantern house, featuring a 4-watt UV bulb and an electrified grill.

The bulb attracts the bugs, and when they get close, they’re zapped by the powerful transformer.

Some of the bugs will fall through the bottom of the lantern, while others stick directly to the light.

Light Action

Light attracts bugs more than anything else. It doesn’t matter whether it’s your outdoor lighting or the enthralling of a zapper.

Now, if you’re never comfortable at your backyard because of the bug, or don’t have the energy to keep swatting mosquitoes, you’ll be better off with this bug zapper.

The UV bulb offers a convenient way to attract the bugs for elimination.

The only question is whether Flowtron BK-40D is capable of killing the pesky insects.

Zapping Action

The zapping action of Flowtron BK-40D is pretty interesting and effective, too.

Now, assuming you switch the zapper on, the bulb's compelling UV light attracts the insects.

Once they get close enough to the bulb light, they get electrocuted by the powerful voltage transformer.

While in operation, you might hear the popping sounds of the insects as they get eliminated, and at times, it might even send the zapped insects on your way if you’re close enough.


Flowtron BK-40D is a versatile bug zapper, and it’s designed to eliminate all forms of insects.

See, the light doesn't always attract some bugs such as mosquitoes, but this zapper has a solution for such bugs.

It features a cartridge containing octenal, a chemical that readily attracts biting insects.

However, if you’re sensitive to chemicals, you don’t have to use the cartridge.


Flowtron BK-40D has a generous coverage of 1-acre.

For those with smaller yards, the coverage might be on the higher side, and might even attract neighboring bugs.

However, for those needing to cover a large area, it can’t get any better than Flowtron BK-40D.


As with any other electric equipment, safety is paramount when operating Flowtron BK-40D.

Fortunately, the zapper is designed to keep the little hand and pets from getting zapped.

The grated exterior polycarbonate grid with small openings keeps the small fingers away from electrocution.

Still, it's prudent you take precautions and hang the lantern higher away from kids' reach.


Setting up this zapper is pretty straightforward.

All you've to do is figuring where to hang it since it features a strong metal hook at the top.

For the best performance, hook the zapper to a tree or metal pole.


The only real drawback of this zapper is the bright light. The light can, at times, get a bit dizzying, especially to those with sensitive eyes.

However, you can avoid this by placing the zapper at least 25 feet from your household.


  • Effective bug elimination technology
  • Durable build
  • Extensive coverage
  • Uses both light and chemicals to attract bugs


  • Bulb light is too bright

Flowtron BK-15D Electronic Insect Killer - Best for Average Yards

Looking to hold a cookout with friends and family, without worrying too much about the bugs?

The Flowtron BK-15D Electronic Insect Killer is a great zapper to have and will not engage a mosquito Armageddon to benefit neighbors.

Instead, it only covers half an acre, a range well within a majority of the yards.

Its step down to the Flowtron BK-40D we’ve just reviewed above.

Flowtron BK-15D Electronic Insect Killer

Features and Benefits

Design Quality

Flowtron BK-15D is designed with the same high build quality as its larger sibling.

It’s a reliable and durable option that doesn’t skimp on the performance.

It’s also a long-lasting and a weatherproof option that will stand up to whatever Mother Nature throws.

Notably, the top has a steel exterior acting like a pitched roof of a home, allowing rainwater to safely drip down the edges, far from the electrical grid and the UV lamp.

The zapper is around 8.5 x 8.5 x 13.5 inches, and depending on where you want to place it, it can be a bit large. However, it doesn't necessarily mean it's an issue since all you've to do is to take some measurements.

High Voltage Transformer

Flowtron BK-15D zapping performance is astonishing in its own right.

The high voltage transformer is effective at zapping the bugs and will eliminate all the bugs around.

Another cool feature with the transformer is that it runs without interruption, and so, you can leave it to run continuously, while at the same time eliminating the bugs.

Double Lure System

Same as Flowtron BK-40D, Flowtron BK-15D uses both a 15-Watt bulb and pheromone cartridges to attract insects.

The chemical attractant lures the biting insects such as mosquitoes, while the UV light from the bulb draws any type of insects.

Together, the double lure system forms a system that is just as effective during the night as it is during the day.

Multi-Bug Elimination

The double-lure system is effective at dealing with nearly any type of flying insect.

So, whether you’re worried about flies, moth, beetles, mosquitoes or gnats, this zapper can eliminate all of them.

The only flying insects it can’t handle are the bees and yellow jackets since they’re not attracted to light.

Clog Protection

The biggest issue with most of the bug zappers is clogging. When the zapper gets too clogged with bugs, it short-circuits, causing the unit to fail.

However, you don't have to worry about that with this zapper because it's designed using a patented, non-clogging grid to protect it from getting back up and failing.

So, the zapper offers an effective, uninterrupted coverage than other zappers do.


Another issue with zappers is they're too open and can attract and kill other animals. Plus, the electric current can harm your curious kids, too.

However, Flowtron BK-15D is encapsulated with a grid protecting other animals and kids from touching the transformer. 


  • Nice design
  • Easy to set up
  • Ideal for medium-sized yards


  • Short cable

Best Bug Zapper Buying Guide

Best Bug Zapper Buying Guide

With plenty of options in the market, choosing the right bug zapper for your needs might feel quite challenging.

The good news is, we’ve compiled a comprehensive buying guide to help with your selection process.

But first, let’s look at the different types of bug zappers in the market.

Types of Bug Zappers

There’re different types of bug zappers, but we shall only look at the three popular options.

  • Insect Traps

These zappers work by luring insects to the device with light, and then a vacuum sucks them into a chamber.

The chamber on the insect trap contains a dehydrating agent that sucks the life out of the insects.

  • Electronic Zappers

The electronic zappers also use light to lure the insects into the device.

However, rather than trapping the insects, they electrocute them when they touch the unit’s grid. There’s usually a tray at the bottom of the zapper that catches the debris.

  • Electric Swatters

The electric swatters resemble a tennis racket, and they run on batteries.

The mesh surface features an electric grid that electrocutes the insects when you wave the swatter at them.

Features to Consider When Purchasing a Bug Zapper

Now that we know the various types of bug zappers, let's look at the features to consider when selecting a bug zapper.

  • Indoor/Outdoor Use

Some zappers are designed for use inside your house, while others are designed for use in the field.

Some of the common types of indoor zappers are insect traps, electronic zappers, and electric swatter. Most of these don't release any harmful chemicals, and their range is pretty limited.

On the other hand, outdoor zappers are designed for use in the field.

Most of these zappers are bulky and have extensive coverage.

Common types of outdoor zappers include; solar-powered zappers, battery-powered zappers, and garden-lamp combo.

  • Range

A zapper range is a crucial feature, and you need to pick one with a large enough range to cover the area you need to eliminate bugs.

However, the biggest range is usually not the best: many homeowners make the mistake of buying a zapper with an extended range, which only ends up attracting bugs from the neighboring yards and areas, as opposed to killing pests already present.

To find the best zapper range, measure your yard, and choose a zapper with a range fitting the area you’re trying to protect.

  • Noise Level

The fan-based zappers normally generate a low humming noise operation. On the other hand, the electric-based zappers might generate a popping sound when the insects are killed.

Whatever model you pick, you should always ensure you pick one that is quiet as possible, especially if you plan to use it in your bedroom, nursing area, or study room.

  • Design

The design and elimination process of your zapper will depend on the type of insect you need to target.

For instance, zappers using light as an attractant are suitable for bugs such as moths, mayflies, crane flies, and beetles.

And because light doesn’t attract all insects, you may want to choose a zapper that lets you add chemical attractants. This is the case of biting insects such as mosquitoes.

Finally, if you choose a zapper that electrocutes insects, choose one designed to protect you from accidental contact, so you don’t end up injuring yourself, your kids or pets.

  • Timer

Depending on your needs and budget, you might also pick a zapper with a timer, which turns off the zapper on or off on a programmed schedule.


Bug zappers offer an effective and hassle-free way to eliminate the bugs.

And depending on the model, you can also get an option free of the toxic chemicals, so you won’t need to worry about your health.

The above-listed bug zappers will allow a more efficient bug elimination, and all you’ve to do is pick a model suiting your needs.


For how long should I leave the zapper on?

A god zapper should work 24/7, but most users would keep it on from dusk to dawn. The system kills the insect's breeding cycles and keeps all the flying insects away from your house. 

Will the bug zapper kill mosquitoes only?

No, the bug zapper attracts a lot of insects, both harmful and innocent. Unfortunately, it ends up killing all of them. This is dangerous to the insects that have beneficial aspects for the environment.

Do the bug zappers cause a fire?

They are not that dangerous but keep the wires away from hazardous zones to ensure it remains safe when in use. The electrical cord should be kept secure if you are using it outdoors.

At what point should I replace the bulb on the zapper?

If the bulb stops functioning or turns black on the ends, it is time to replace it. Additionally, if you notice more flickering and dullness, then replace the unit quicker.

Is it easy to attract flies to the bug zapper?

Yes, the flies will move closer to food, so if you want to lure them, get food. Honey and sugar are common and should be smeared on your bug zapper.
