YISSVIC 20W Fly Zapper: Indoor UV Bug Trap with Extra Bulbs
Product description
What it is and what it does
The YISSVIC 20W Fly Zapper is an indoor electric insect trap designed to attract flying pests using dual 365nm UV bulbs and eliminate them instantly with a high-voltage grid. Built for home use, it offers a physically based solution that avoids chemical sprays, delivering odour-free operation in spaces like kitchens, bedrooms, and living areas.
How it works in practice

The device attracts mosquitoes, midges, gnats and moths with UV light, then zaps them on contact. Its 4300V grid provides quick efficacy, while the insulated ABS shell keeps the exterior safe to touch. The unit can be placed on a counter or hung on a wall using the 1.8m power cord, giving flexibility to fit various room layouts.
Design and suitability
With a modern square silhouette and a PU leather handle, it blends into typical home decor. The wall-mount or free-standing option makes it versatile for kitchens, garages, bedrooms or living rooms. The removable collection tray at the bottom simplifies maintenance, simply pull out the tray, sweep debris with the included brush, and slide it back in.



Pros and practical limits
On the plus side, it offers a chemical-free approach to pest control and is odourless. It is easy to operate via a side-mounted power switch and requires minimal ongoing maintenance thanks to the removable tray and spare bulbs. A potential limitation is that effectiveness hinges on the insects being attracted to the UV light, in some rooms with competing light sources or strong outdoor insect activity, results may vary.
Who it’s for

This zapper is well suited to households seeking a straightforward, low-odour solution to indoor flying pests in common living spaces. It’s particularly suitable for kitchens and bedrooms where chemical sprays are less desirable.
When it makes sense to buy
If you prioritise a non-chemical method, value a long-term maintenance plan with spare bulbs, and want a device that can sit neatly on a worktop or be mounted on a wall, this model fits that use-case. It may be less effective in spaces with heavy outdoor insect influx or bright competing UV sources.



What to check before buying
Confirm the room size and lighting conditions to set expectations about capture rate. Consider placement height and access to the 1.8m cord for best coverage. If you value easy cleaning, the bottom tray and included cleaning brush are helpful.
A practical use example

Imagine a busy kitchen after sunset. The zapper sits on the counter near the dining area, drawing in gnats and small flies with its two UV tubes. A quick check of the tray reveals a few captured insects, easily cleared with the brush and tray reinserted—no sprays, no odours, just a simple clean-up and peace of mind.
Quick comparison note
If you weigh options between chemical-free traps and traditional sprays, this unit sits in the middle ground: straightforward to use, with a focus on durability and low ongoing cost thanks to extra bulbs. It won’t replace heavy-duty pest control in larger, open spaces, but it’s a solid choice for individual rooms.



What’s included
Pre-installed UV tubes plus 2 additional replacement bulbs are provided, alongside a cleaning brush and a removable tray for easy maintenance.
FAQ
- How do I maintain the device? Remove the tray, brush away debris, and slide it back in. Replace bulbs as needed with the included extras.
- Is it safe around children? The outer casing is insulated and designed to prevent contact with the internal grid, but as with all electrical devices, keep out of reach of curious hands.
- Can it be used in a garage? Yes, it’s designed for indoor use and can be wall-mounted or stood on a surface, provided there’s a power outlet nearby.
Decision time
Is it worth it? It’s a practical, odour-free option for targeted indoor pest control, particularly if you value a non-chemical approach and straightforward maintenance.
