I will give my hunting buddies some. I've had the same bottle of the concentrate for 4 or 5 years (using the last of it this spring). I keep it in a cool place when I don't need it and it's still very effective. I will mix a quart bottle of spray at a time and I wet everything thoroughly, hanging on a clothes line. I've read, it is effective for up to 28 days. I will normally reapply when I wash my clothes or half way through the season.
