We get asked all the time on when is it time to remake a set. It’s not the length of days it’s been there, it’s weather conditions that are our determining factor. A big rain can form a crust over the set basically keeping it from firing. Animals have a keen sense of smell and will still be able to smell the bait and lure you’ve used, but the dirt over the set is the concern. So if you’ve put a trap in and have been unsuccessful for the first couple days, don’t be concerned with resetting it unless there has been a big rain.
