Do bug zappers effectively kill gnats? Interested in experiences or expert advice!
In my experience, yes, they do! I’ve had a zapper on my porch for months and noticed fewer gnats around.
I second this. But make sure it’s a zapper that emits UV light at a wavelength that attracts gnats.
But aren’t bug zappers also killing beneficial insects?
That’s true! It’s a trade-off situation. Better to use gnat-specific traps.
| Bug zappers can kill some gnats, but honestly they’re not super effective. Gnats aren’t always strongly attracted to UV light like moths or flies. |

I tried using one on my patio last summer. It zapped a few, but most of the gnats just hovered around my plants instead.
@LightChaser92 Right, I noticed the same. They go for moisture more than light, so a zapper isn’t their main weakness.
If gnats are the problem, you might be better off with sticky traps or apple cider vinegar bowls. Works way faster in my experience.
I keep a zapper by my back door and it does catch some gnats, but way more mosquitoes and moths. It’s not a total solution.
@BugBattleBecky Totally agree. I think bug zappers are more of a “bonus” against gnats rather than a fix. You need to tackle breeding spots too.
The key is draining any standing water nearby. I used to think my zapper was failing, but once I removed the water sources, the gnats disappeared.
Some studies show bug zappers mostly kill harmless insects instead of pests. So don’t expect them to be a magic bullet for gnats.
I prefer natural repellents. Basil or lavender plants around the porch actually made a big difference for me.
I still keep a zapper out though—it’s satisfying to hear that “zap” now and then, even if it’s not the most efficient tool
