ole442,, NC has the law against relocation of animals that can be rabies vectors,,, so we too have to kill the offensive critters.
The differences are HOW you kill them.
I can legally shoot a critter, I can use a gas chamber, or a guillotine. (The guillotine is allowed because the State uses them to kill animals they test for rabies.) I can also use a kill type of trap.
BUT,, in most city limits in this country,, shooting a firearm is illegal. So,, that option is out. I use a lot of live traps,, remove the animals from a home,, and kill them at my place.
By doing this,, it also reduces the chances of offending a neighbor of a customer if they were to happen to see something they disliked. Now I also use kill traps. Very efficient too! But skunks get the live traps. No need to have them stink up the neighborhood.
