STEM Flying Insect Trap – Indoor Light Trap for Fruit Flies & Gnats (2 Plug-ins, 4 Cartridges)

The STEM Flying Insect Trap offers a simple, odorless way to attract and capture a range of flying pests without chemicals. Two plug‑in devices provide flexible coverage across rooms, while four sticky cartridges handle ongoing capture. The soft blue light helps lure insects in a discreet, low‑noise design that blends with home decor.

Designed for indoor use, the trap runs continuously around the clock to help reduce nighttime nuisances and daytime interruptions. It is formulated with people and pets in mind when used as directed, and it does not rely on sprays or odors. Replace cartridges when they become full to maintain effectiveness and keep the trap performing at its best.

How it works

The device uses a gentle blue UV light to attract a variety of flying insects, then the sticky cartridge traps them on contact. Because there are no insecticides involved, there is no chemical smell or spray, making it a low‑maintenance option for many spaces. Running continuously, the system can help reduce the presence of common kitchen and living area pests over time.

• Attracts and traps mosquitoes, gnats, fruit flies, moths, and other small flying insects
• No insecticides, no sprays, no mess
• Quiet operation suitable for living rooms, bedrooms, and offices
• Compatibility with Raid Essentials light trap refills for easy replenishment

What you get & setup tips

Included with the STEM Flying Insect Trap are two plug‑in devices and four sticky cartridges, designed for immediate use and multi‑room coverage. Set up is simple: remove the protective seal from the cartridge, insert it into the base, plug the unit into a wall outlet, and adjust the 90‑degree rotating plug to fit your space.

• Two plug‑in devices for flexible placement
• Four sticky cartridges ready to deploy

Maintenance is straightforward—replace cartridges when full and clean the base window if needed. Place units away from strong air currents and direct sunlight for best performance, and position them where activity is highest (near fruit bowls, trash bins, or entryways) without creating clutter.
