Katchy Indoor Insect Trap Review

The Katchy Indoor Insect Trap is an innovative way of dealing with flying insects around the home. Unlike bug zappers that use light to attract insects and then zap them, the Katchy insect trap takes a modern approach that’s completely more modern than everything else.

Instead of zapping insects and making noise in the room each time an insect is neutralized, the Katchy indoor insect trap combines fan suction, attractive UV light, and a sticky pad to trap insects, all in a fashionable design that creates a safe and sanitary solution to flying pests in the home. You no longer have to rely on annoying zappers to trap indoor flying insects anymore.

About the Katchy Indoor Insect Trap

As mentioned, the Katchy fly trap uses a different approach from bug zappers, but in reality, both use the same mechanism to attract and trap the insects, only the method of elimination differs. First, the trap uses an ultra-violet (UV) light to attract the insects, making it effective at night with surrounding lights turned off. So, you’ll want the Katchy light to be the brightest in the area so all the flying insects are attracted to it easily.

Once the insects get close to the light, there’s a fan that sucks the bugs into the trap. Once the insects are sucked into the holding area, and with the fan constantly working against them, it’s practically impossible for them to crawl or fly up the trap.

At the bottom of the trap, there’s a sticky board where the insects will land (or get blown directly into it from the fan). The bugs are then stuck to the glue and they can’t move. This is the same mechanism used on the sticky tape that hangs from the ceiling, only that it’s more hidden inside the beautiful device so it doesn’t look gross.

On the other hand, most bug zappers like the Flowtron BK-40D Electronic Insect Killer use ultra-violet lights to attract insects, too. However, instead of blowing the insects into a trap or jar, the bugs are attracted to the center of the device, where they are electrocuted, usually between two metal grids, and then they drop dead into a collector at the base.

While they’re effective at killing flying insects, the downsides include the constant noises each time an insect is electrocuted, and they don’t necessarily kill the specific bugs that bother you.

How to Use the Katchy Insect Trap

You can use the Katchy indoor trap pretty anywhere, but ensure it won’t get wet and the location has a power source. It comes with a sizeable plug that you can use in a standard outlet, but you can alternatively power it via USB.

Measuring 5.5 x 5.5 x 9.1 inches and weighing only 1.37 pounds, the Katchy trap is a small and portable device that you can use at home, likely in the kitchen near your fruit basket. For efficiency, you should place it around wherever you’re seeing the most insect activity.

Also, you can take the Katchy camping with you, and it will fit well in your tent. The portable and small size means that it won’t add more weight to your vacation itinerary.

This trap works best with the lights off so it can attract more bugs to the UV light. It has both manual and automatic modes, the latter uses a light sensor at the top of the unit so the UV light will only come on in the evening when the other lights are off.

Katchy Indoor Insect Trap Specs

  • Range: The Katchy indoor insect trap has a coverage area of 320 square feet, and since it uses UV to attract bugs, it works best when it is dark.
  • Capture mechanism: Its three-level trapping system uses light to bugs in to the fan, which sucks them into the system, and the glue trap which holds then in place. Since the fan is located at the top of the trap, it prevents insects from flying back out.
  • Quiet operation: On the Katchy insect trap, the fan is the only moving part and it runs relatively quiet. The fans don’t need enormous power to keep the insects trapped, all it has to do is maintain rotation in a single direction to keep them inside the trap.
  • Killing Power: The glue paper trapping method is great for small insects. Since the vents at the top of the Katchy don’t allow for larger bugs such as house flies or bees into the trap, so it won’t work for them.
  • Ease of use: This trap can be set manually or in automatic mode. It comes with a sensor that will allow it to automatically turn on at night. Using it is pretty straightforward, all you need to do is plug it in and set on automatic mode and it will eliminate annoying household insects.
  • Safety: The Katchy doesn’t use any chemicals or toxic substance to kill bugs, just a UV light, a soft blowing fan, and a sticky board. This makes it safe to use anywhere in the house.

Elsewhere, the Katchy Insect Trap sports an attractive design that will fit anywhere in your home without being obtrusive. It comes in white or black colors, but the UV light is always a purple-ish color. You can use it in the kitchen office or on your outdoor patio.

Cleaning the Katchy Indoor Insect Trap

All insects captured by the Katchy are held by the glue trap, so it needs to be cleaned out once it is full. How often you clean it depends on how many bugs you’re catching. Some people can go a month or more on one trap; that should be ideal unless you’re dealing with a serious infestation.

Replacing the glue trap is straightforward: Just press the release button on the side of the Katchy and the bottom drops open. From here, you can empty the glue board directly into your trash without ever having to touch it. Once that’s done, install a new glue board into the device and you’re ready for another cycle. The Katchy Refillable boards are available in 4-pack, 8-pack, and 24-pack sets.
