It has been years since I trapped too but I used to just put them to sleep and they wouldn't scent. I used a 4' hoe to rough up the area and just cut the top end so it had a flat spot. Then I fastened 2 angle brackets to the top (basically these could be loosened and a syringe hooked under it...a jab pole). I used acetone and put in the syringe. Just move slow talking to the skunk and you let it sniff the needle, this slow movement keeps the skunk from spraying (usually!). Place the needle right behind the front leg and push to stick the needle into the skunk. Then just push the contents into the skunk. Pull it out and back off. The skunk will get sleepy and start yawning and go to sleep in under a minute. Tehn tap the skund on the nose to make sure it is asleep and put another ccor two in the needle and insert right into the heart to make sure it is dead. I did several skunks in one day once and had them in the trunk so this works. Easier to see then to explain. Any ? just e-mail.
