Late summer into fall is peak season for tiny flies hovering over the fruit bowl, the trash can, and the houseplants. Indoor fly traps are one of the fastest-rising home products on Amazon right now, and the category splits into two very different approaches: plug-in light traps and liquid bait traps. They’re good at different bugs, so the first job is figuring out which one you have. Here’s how we’d sort it out, and the traps we’d put on the counter.

First: Which Bug Is It?

Where the flies hang out tells you most of what you need to know. Fruit flies cluster around ripening fruit, recycling, and the trash, and they’re drawn to anything fermenting. Fungus gnats hover around houseplants and breed in damp potting soil. Drain flies are fuzzier, moth-like, and show up near sinks and shower drains. Bait traps are built for fruit flies. Light traps catch a broader mix of small flying insects, including gnats. Drain flies are mostly a cleaning problem, so a trap alone won’t fix them.

Plug-In Light Traps

These plug into an outlet, use blue or UV light to draw small flying insects in, and hold them on a sticky pad. No spray and no zapping, which makes them easy to live with in a kitchen or next to a plant shelf. The tradeoff is the ongoing cost: the sticky pads or cartridges get used up, so budget for refills rather than thinking of it as a one-time purchase. Placement matters too, since they work best close to wherever the bugs gather.

Our pick: Zevo Flying Insect Trap, Plug-In Base + 3 Refills. The long-running favorite in this category, with tens of thousands of ratings behind it. The adhesive cartridge faces the wall, so you don’t have to look at the catch, and a blinking light reminds you when it’s time to swap. The catch is that cartridges are proprietary, so you’re committed to Zevo refills. Check price on Amazon →

Trending pick: DOVSAV UV Gnat Trap with Suction Fan and Timer. One of the fastest-selling new releases in Home & Kitchen right now. It adds a small fan that pulls insects down onto the sticky pad, runs off USB power, and has 6- and 12-hour timer modes if you don’t want it on all night. It ships with 10 replacement pads. It’s newer, with a much shorter track record than Zevo, so treat it as a promising option rather than a proven one. Check price on Amazon →

Bait Traps

If your problem is squarely fruit flies around the fruit bowl, a food-based bait trap is the simplest fix: no outlet, no light, just a lure fruit flies can’t resist. It won’t do much for fungus gnats or drain flies, since they aren’t chasing the same smell.

Our pick: TERRO Fruit Fly Trap, 4-Pack. Apple-shaped traps that sit in or next to the fruit bowl without looking out of place, with a window so you can see the catch and the lure level. Each trap lasts about 45 days, and the 4-pack covers roughly six months. Reviews are more mixed than the plug-in traps. The common complaint is weak results when the flies are coming from somewhere other than where the trap sits, which is another reason to find the source first. Check price on Amazon →

The Step No Trap Replaces

Traps catch the adults, but the flies keep coming as long as they have somewhere to breed. Move ripe fruit into the fridge, rinse recycling before it goes in the bin, take the trash out more often for a week, and let houseplant soil dry out between waterings. Do that alongside a trap and most infestations fade within a couple of weeks. Skip it and the trap just keeps filling up.
