Centex said it all, "crazy and paranoid". We have the luxury in farm country here to reduce/eliminate the Damage (ADC - Animal Damage CONTROL) by spooking the coyote enough that he leaves the immediate area and takes the Damage with him.. Catch/shoot his mate, kids, family, neighbors and he realizes this is not a safe address to keep his skin. Lots of human association/activity in our area seems to spook the REMAINING coyote(s) enough to cause some "Flight". Usually plenty of small mammals on other areas where he can "make a living". In another month different story as Ma will be lookin/picking a den site as she gets chubby and they have a down payment on their locale. If you are in Texas, trapping a ranch (lots bigger than our 50-100 cow farm/ranches) European Style (meaning eliminating everything that competes against what you want) then its a tougher row than a lot of places. Restricting your contact to the areas coyotes visit is probably the best advice I can muster. Every other day checks or close examination of sets are a No No, for me. You are not fur trapping. Boot leather over the best spots your previous catches were made to find some returning sign of the remaining ones (even a denning spot) is what I do, then leave for at least a week or 10 days, come back and re-check for activity and set traps/snares WITHOUT any lure or attractant. Come back in 1 week or so and add your attractant as if you were walking/driving through. No dirt hole for me. You can use a call if you know what/how to do that and the 5000.00 thermal scopes are quite an advantage now-a-days. That is roughly the way I have done the tough ones in here. Yes Sir mentioned scent association and I guess the way I use is similar to his experience. .......................the mike
