Natural attractant bait station that lures flies away from entry points
Mobile app to monitor fly activity and refill reminders
Weatherproof design for outdoor use

Target Users: Homeowners with garage or backyard doors that must remain open during summer months, especially those in suburban or rural areas with high fly populations.

Revenue Model: $79 one-time hardware purchase, plus $12/month subscription for bait refills and app data analytics
