Stem - Flying Insect Fan Trap for Indoor Bug Control, Plug-in Fan with UV Light, Starter Kit Includes 1 Device and 5 Glue Traps

I like this product for catching fungus gnats that hitched a ride inside after I brought my outdoor plants inside for the winter. It seems to do well attracting the adults, while I work on stopping the source they're originating from. It's super quiet. I have to put my hand over it to feel if it's working sometimes. There's an indication light, but I don't always trust stuff and like to check anyway. I have it plugged in and running 24-7, but there is an option for a timer. It's a simple touch screen with lights and pictures as buttons. It seems to catch bugs easily. I also have the plug in type that works well. I think they do about the same job attracting and trapping critters. It came with a refill pack of six discs of the sticky cardboard you place inside, that catches the bugs. It's nice not having to immediately buy replacement parts. It's powered by a USB style plug in cord which is included. It looks decent in a room. It's nice that you can't see the bugs on the sticky pad inside.

This work great

Pros: - Works really well for light-focused bugs - Much better than other UV fly traps I've tried that don't have a fan. Worth the extra cost Cons: - Not going to work well for bugs that are more scent-focused (like fruit flies or large house flies) - Safety hazard if it is placed where children can look at the light - The slow-speed mode for the fan causes the device to emit a high-pitched coil whine noise. Not a big deal since the fan isn't very loud in high-speed mode - Doesn't automatically turn back on after losing/regaining power

Don’t waste. your money on this product.

Works awesome! Catches a lot of bugs. Including stinkbugs. But those big stupid idiots get stuck in the bottom of the funnel and block it so you have to poke them through or shake them out. I'm very glad it catches them. I might just try to Dremel the hole larger. It makes a noticeable difference in how many bugs are bumbling around the house.
