When you've got a Zevo Flying Insect Trap in your home, gnats, house flies, and fruit flies don't stand a chance resisting the hypnotizing blue and UV light, that draws in insects. Once there, they get stuck on the adhesive pad, and never bug you again. It may help to move your Trap to another location, where gnats can easily see it. Once you move it, give it a week or so, to see if the new location is better. Need more help? We're here, and happy to assist. Call us Mondays through Fridays, from 9 AM to 6 PM, EST. Our number is 1 (800) 374-9429.
