How does the STEM Flying Insect Trap work?

A UV light attracts flying insects and a small fan pulls them onto a sticky glue card. There are no chemicals; you replace the card when it is full.

What insects does it catch?

It targets mosquitoes, house flies, fruit flies and similar small flying insects. It is not designed for crawling pests like ants or roaches.

STEM rates it for rooms up to 400 square feet. In open-plan spaces, place it near the insects' source rather than in the middle of the room.

Yes, when used as directed. It is chemical-free and the adhesive is enclosed, but keep the cord and the unit itself out of reach.

It is waterproof and suited to enclosed patios and screened porches. It is not built for open outdoor weather or rain exposure.

Replace the card when it is covered with insects or dust, which in a busy kitchen can be every few weeks. A clogged card reduces the fan's pull.
