As Nomercy mentioned....good Camo and concealment will help You be a better Hunter....and scent control.Are You wearing under arm spray,shaving and splashing cologne all over Yourself?
First of all You need to shower with scent-free soap...Your Hunting Clothes need to be washed with scent-free detergent and dried with the earth scented dryer sheets or hung to dry outside the sprayed down with scent-killer spray before You put them on...its just like going Deer Hunting...You don't want the game Your Hunting to be able to smell You,I also wear rubber Hunting Boots and leave then outside and use them for Hunting Only.
There's plent of things You need to do before You even go out to Hunt to keep the Coyote's from smelling You.Be sure to have good Camo and stay hidden in the shadows or have some cover to hide Your body or outline....limit Your movement and sneak in to where Your going to set up to hunt.
Not so sure about Your Trapping Laws but we have to buy a Trappers Tag/License and our name and phone number has to be on the traps...and all traps have to be checked every day within a 24 hour period or we can be fined.
Coyote Hunting should be for enjoyment and a learning process,if You ask around You should learn a lot for free just by asking questions and reading other post and hints about Hunting them...learn as You go and share Your experiences with others!
Once You do shoot a Coyote...what are Your plans on what to do with it...You going to have it mounted or the hide Tanned....goin to give it away to a Trapper so he can skin it and sell the hide/fur?
