Snares will always remain an important trapping tool and wildlife control device as long as misuse does not become a factor. Avoid these possible scenarios by always using the minimum required for your target species. Try to keep your snaring location contained to the target animals home range and avoid populated areas. Sometimes an animals range will overlap with the public and domestic animals. Always try to find a way to avoid non target species captures.
Make sure you contact your local wildlife agency to become familiar with your states regulations, again this is critical. The common rule when setting snares is to THINK. Your actions will have an impact on other wildlife and other trappers. You have an obligation to the wildlife and those trappers to always be responsible and represent the tradition and or job in the best possible way.
