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.

Spectacular! Bought some soil that was infested with fungus gnats and fruit flies bought 2 of these to help and within 15 minutes they had both caught 5 each. Theres a circle in the center under the light and I put a felt pad there with apple cider vinegar we'll see if that increases the capture rate
