STEM Flying Insect Trap Plug-In Two-Pack — Soft Blue UV Light, Silent Indoor Fruit Fly & Gnat Catcher with Replaceable Sticky Cart

The STEM Flying Insect Trap is a plug-in, insecticide-free blue-light device that quietly attracts and captures fruit flies, gnats, mosquitoes, moths and house flies using replaceable sticky cartridges.

Designed for indoor use around kitchens, bathrooms, entryways and other rooms where flying pests gather, this compact two-pack offers continuous, hands-off control without sprays or messy traps. The soft blue light lures insects to a dual-sided adhesive cartridge; installation takes moments, and cartridges are swapped out when full. Compatible with common light-trap refills for added convenience, the STEM units aim to reduce visible flying insects while operating discreetly day and night.

How does the STEM trap attract flying insects?

The unit uses a soft blue light to draw flying pests toward a replaceable adhesive cartridge. Rather than emitting chemicals, the light mimics the visual cues that many small flies and moths follow, leading them into the sticky surface where they become trapped.

• Soft blue UV-style LED light optimized for indoor flying pests.
• Dual-sided adhesive cartridge increases capture surface area.
• Continuous operation keeps attraction active around the clock.
• No sprays, fumes or loud fans—silent, odorless performance.

Where should I place the plug-in devices for best results?

Position each unit near areas where insects congregate—fruit bowls, trash cans, sinks, or entryways—placing them a few feet from the source for effective coverage. The 90-degree rotating plug lets you orient the light and cartridge toward the room rather than into a wall outlet for better exposure.

• Mount in kitchens near fruit or compost bins to catch fruit flies and gnats.
• Place by doors, windows, or entryways to intercept moths and flying insects.
• Avoid bright competing lights or outdoor-facing windows for optimum attraction.
• Use two units in larger rooms for broader coverage and redundancy.

How do I install and maintain the STEM flying insect trap?

Installation is straightforward: peel the protective layer off the sticky cartridge, insert it into the trap base, and plug the device into an indoor outlet. Replace the cartridge when it becomes densely covered with insects to keep trapping performance consistent.

• Peel protective film, seat the dual-sided cartridge, and plug in.
• Rotate the 90-degree plug for optimal light direction and positioning.
• Swap cartridges as needed; compatible with many standard light-trap refills.
• Wipe the exterior occasionally to remove dust and maintain light output.

Is the device safe to use around people and pets?

The STEM trap operates without insecticides and produces no sprays or odors, making it suitable for homes with people and pets when used according to the instructions. The adhesive cartridges keep captured insects contained, and the low-voltage LED light runs quietly and cool to the touch.

• Insecticide-free operation when used as directed.
• Cool-running LEDs reduce burn risk and avoid heat sources.
• Quiet, unobtrusive for use in living areas and kitchens.
• Keep out of reach of children and pets to avoid tampering with cartridges.

Who is this for: homeowners, renters and food-preparation spaces seeking a low-effort, chemical-free approach to reduce flying pests indoors. The STEM Flying Insect Trap suits kitchens with persistent fruit flies, living rooms and entryways where moths and mosquitoes invade, and anyone preferring a discreet, 24/7 option that pairs easily with widely available replacement cartridges.
