Rodent Surveillance Setup


(Smart Monitoring)

For properties experiencing recurring rodent activity, we offer optional surveillance monitoring to better understand movement patterns and nesting behavior. When Wi-Fi is available, we can install discreet monitoring devices in key pathways to track activity in real time. This allows us to place traps more strategically, respond faster, and deliver more effective results—all at no additional cost to you. It’s a smarter, data-driven approach that helps ensure the problem is solved thoroughly, not just temporarily
