I have a package of Active Scrape, the one with the hanging bag that drips. It is still unopened, but I bought it last yr. Is it to old to use? I know I can get a new bottle of fresh, but wondered if this could be used, since it is unopened.

Anyone? Also, does this really even work? Never used it, but sounded good to me.

I use one every year and have had many deer walk right up to it and smell it.
