Hello Dear Consumer. For your Zevo Flying Insect Trap, it's recommended to check the refill cartridge every 15 days or as needed. You can replace it sooner if it's full of insects. So, changing the insert after 12 days is totally fine if you feel it needs it. Keep an eye on the blue light flashing, it’s just a reminder to check, not a must-change signal. Keep those bugs trapped! If you need assistance please give us a call at (866) 215-1297.

Hi Angie! For best results, try moving the trap to a different spot where you see more flies. Also, make sure the blue light is on, showing the cartridge is properly inserted. Check the cartridge every 15 days and replace it when full. Our products undergo rigorous quality checks, and your feedback is important to our Quality Assurance Team. We would love to hear more about your experience and assist you further, so please call us at (866) 215 1297.
