Fencing, where practical such as premier athletic fields, will also keep skunks out of an area. Keep in mind that gates must remain closed at all times to prevent skunks from entering a fenced area. When necessary, skunks can be trapped and removed from areas where they are unwanted. A live trap baited with fish, fish-flavored cat food, chicken parts, bacon, or peanut butter on bread works well. Traps should be 9x9x24 inches or smaller.
Smaller traps are less expensive and reduce the chance of spraying.
Wrapping the trap with a tarp may entice the skunk to enter the trap. Given the controversy surrounding how to manage a trapped skunk and whether it should be humanely destroyed or not and what methods of destruction are considered humane, it may be best to contract with a wildlife control company when removal or disposal are issues. There are no biological agents available for skunk control. There are no chemicals registered to control skunks. If you're problem results from the digging activity of skunks in turf to access grubs and other insects, the use of a least toxic insecticide to control the insect problem will likely eliminate the skunk digging problem as well.
