I agree with the conibear traps, and live traps for removal. The faster they are euthanized, the less chance of having them spray. I would consider maybe a live trap with a bag over it also to reduce or eliminate residual smells after the skunk is removed. You must be careful because in some areas, skunks can be often known carriers of rabies. When handling anything around the skunks, just be sure to wash thoroughly and keep your pets up to date on vaccinations. Once you have them in a live trap, you may either relocate them (illegal in many areas) which I prefer to do or a well placed shot to the head will usually keep them from spraying but, not always! If you are able and are a good shot, you can shoot them with a .22 but, only if you feel you can make a clean head shot to reduce the chance of spraying! Good luck!
