I thought game snares were illegal. IS that not the case for Texas?
Well to get technical "Game" snares are illegal in TX. BUT, feral hogs are classified as pests not game, so they can be snared. To avoid snaring game "deer" you must put what is called a "deer stop" on the snare so that the loop of the snare stops closing when the loop gets down to about a 5-6 inch diameter. This is so deer don't snare their legs.
I've set up 10 snares for hogs on a property with a lot of trails that we hoped hogs were on. My brother in law was the one who had access to the land so I basically let him manage the snare situation after we initially set them up. We snared 3 coyotes and 2 foxes hahaha. He then obsessively moved the remaining snares all over until I think he forgot to set them back out so I guess he has the reaming 5, lost them, or threw them out. This was like 6 years ago. There were no hogs on the property, just bunches of coyotes it seems.
Snaring coyotes and foxes are no issue. They are not considered game and are not protected.
Louisiana may have different rules so it is always best to know what you can and cannot do :)
