Does it work on mosquitoes?

It is listed for mosquitoes, but owner reports are weakest for them. Mosquitoes respond less to UV light than flies do, so expect limited results indoors.

How often do the glue boards need changing?

Replace them when the surface is covered with insects or dust, which in a fly-heavy room can be every few weeks. The unit ships with five boards.

Is it safe around children and pets?

Stem markets it as child- and pet-safe when used as directed because it uses no insecticides. The glue boards are sticky, so keep them out of reach.

Where should I place it?

Put it indoors near the insect problem, such as a kitchen, enclosed patio or screened porch, and keep it away from competing light. It needs an outlet within 6 feet.

How does it compare with a bug zapper?

It is quieter and safer around kids and pets, but zappers generally kill more large flies. This trap relies on glue boards and a fan, so placement matters more.

One gray trap unit and five glue boards. The UV bulb is included; check the listing for replacement board packs.

Our take on the Stem Flying Insect Fan Trap

The Stem Flying Insect Fan Trap is a plug-in indoor trap that uses UV light and a fan to pull mosquitoes, house flies and fruit flies onto glue boards. It is chemical-free and marketed as child- and pet-safe when used as directed. It is a slim, wall-friendly unit with a 6-foot cord, aimed at families who want no-spray control in enclosed patios and rooms where insects gather. Against zappers it is quieter and safer around kids, but it depends on glue boards and a fan, so it needs placement near the insects and regular board changes. Its 2.6-star average across 1,300 ratings suggests many owners found the catch rate disappointing.
