The photos show the tunnels I've located in newly planted sod. They appear to b inline vs a spoke pattern. I've read that before placing bait into a tunnel, it is imparative to locate the main traveling tunnels. I'm hoping for advise from others with more experience doing this. Specifically, do I need to find more tunnels and which ones should b baited ? all efforts with other methods have thus far failed. Thx for any suggestions
