I don't know how effective they will be against your turkey rapers...but they work for our little ones over here...
For once, you can believe the hype. T-Cell is the real deal. Only a couple of things to be careful of, keep it horizontal once lit, not hanging vertically like I did the first year I had one. Take a look at it and make sure you see a wisp of smoke comin out of it and once your blue wafer is white, slap another one in there. Great product.
