STEM Flying Insect Indoor Trap, 1 Device + 3 Cartridges — UV Light & Dual-Sided Adhesive

The STEM Flying Insect Indoor Trap is a plug-in UV light device that lures and captures flying pests using a dual-sided adhesive cartridge—no insecticides required.

Designed for indoor use, this compact, quiet trap uses blue/UV light to attract gnats, fruit flies, house flies, moths and mosquitoes into a disposable sticky cartridge. It runs continuously when plugged in, fits standard wall outlets, and rotates 90 degrees so you can aim the light where insects gather. The kit includes one trap base and three replacement cartridges; additional refills are compatible with common light-trap cartridges for easy restocking.

How does the STEM trap attract flying insects?

The unit emits a soft blue/UV light that draws flying pests toward the trap, then captures them on a dual-sided adhesive cartridge. There are no sprays or chemicals involved—just light plus sticky surface.

• Blue/UV LED targeted to common indoor flying pests.
• Dual-sided cartridge increases capture area and lifetime.
• Continuous operation ensures daytime and nighttime effectiveness.
• Quiet, odorless performance suitable for living spaces.

Where should I place the trap for best results?

Position the trap in areas where insects congregate: near fruit bowls, trash cans, kitchen counters, entryways or behind lights. Plug it into a low-traffic outlet about 3–6 feet above the floor for typical home use.

• Kitchens and pantries to target fruit flies and gnats.
• Bathrooms and entryways where moths and flies enter.
• Living rooms and garages for mosquitoes and general pests.
• Rotate the 90° plug to aim the light without extension cords.

How do I install and maintain the device?

Setup takes moments: peel the protective film, insert the adhesive cartridge, and plug the unit in. Replace the cartridge when it becomes covered with insects to maintain peak performance.

• Insert dual-sided sticky refill into base—no tools required.
• Replace cartridge as soon as capture surface is full or less effective.
• Compatible with Raid Essentials light trap refills for easy restocking.
• Wipe the exterior with a dry cloth; do not immerse in water.

Is the trap safe to use around people and pets?

The STEM trap is designed to operate without insecticides, sprays or fumes, making it a low-impact choice for households with children or pets when used according to instructions. Keep the cartridge out of reach of curious hands and dispose of used cartridges properly.

• Insecticide-free capture method reduces chemical exposure risks.
• Quiet LED operation suitable for bedrooms and living areas.
• Keep device plugged into a standard indoor outlet only.
• Follow directions for cartridge handling and disposal.
