Mafiti Fly Killer 20W Electric Indoor Mosquito & Fly Zapper
Product description
If you’re fed up with insects that keep turning up in the kitchen or living areas, an indoor fly killer can feel like the most sensible “set it and forget it” solution. The Mafiti Fly Killer is a plug-in UV zapper designed to attract flying insects and then trap and electrically dispatch them using charged metal grids—so you don’t have to wave around a mat or go hunting every time one lands.
That said, it’s worth keeping expectations realistic: this is an indoor trapping/zapping approach. It won’t replace good door and window habits, and the results depend quite a lot on where you place it.
The essentials
This electric insect killer uses UV light to attract a range of flying bugs indoors. The manufacturer lists mosquitoes, flies, moths, wasps, gnats and beetles as the intended targets. Once insects are drawn in, they’re trapped and electrocuted in high-voltage metal grids.

Because it’s wall-mount or tabletop usable, it can suit different rooms and layouts. The product is positioned as chemical-free, with no fumes and no smell—an angle that matters if you’re trying to avoid sprays in areas like kitchens or around children and pets.
What you’ll notice in everyday use
The practical day-to-day difference is convenience. It’s powered by plugging it in, so you’re not dealing with battery swaps or charging. The unit is designed to be hangable (wall mount) using the included stainless chain, while the flat bottom can also keep it stable on a worktop or other flat surface.


A simple usage scenario: place it near where you tend to see insects flying indoors—perhaps close to a frequently used kitchen doorway—then leave it running. You’re essentially giving it a consistent “attraction point” rather than reacting each time you spot a bug.

Key points on safety and convenience
Safety is handled with a 360° protective grid cover, aimed at preventing accidental contact with the electrical grid. For households with kids and pets, this kind of physical barrier is a key consideration, especially compared with open-style insect traps.
On the “clean it without hassle” side, the design allows the grids and bottom tray to be removed. The bottom tray can be pulled out and washed, then pushed back in. That’s the bit that usually gets neglected with cheaper traps, and it’s good to see it called out here.
Where it shines (and where it may fall short)

If you’re specifically looking for an indoor electric zapper that relies on UV light and high-voltage grids—without chemicals or odours—this is aligned with that goal. It also feels geared towards regular household use: kitchen, living room, indoor garden or even outdoor yard use is mentioned in the name/description.
However, it may not be the best match if you want fast results in a large, open space. The manufacturer claims it can kill flying insects in an indoor area of 583 sq ft, so in a bigger home or in rooms with a lot of airflow, results could be less satisfying. Also, if insects are entering mainly from a specific source (for example, an open window or a gap), tackling that entry point alongside the zapper usually makes more sense.

Is it worth it?
Worth considering if you want a plug-in indoor fly killer that attracts insects with UV light, then traps and electrically kills them—particularly if you prefer to avoid chemicals, fumes, or smells in kitchen and living spaces. It also suits people who value simple setup (hang on wall or place on a surface) and easier cleaning via removable parts.
It may not suit you if you’re trying to deal with a persistent insect problem across large indoor areas, or if you expect it to override the need for basic entry prevention (windows, doors, vents). It’s a practical tool, but it’s not perfect for every home layout.
