RE: Scents and calls. (is it to early)
I've used scents for twenty years. 18 years ago I found a company which I've been using since 1989. I won't hunt without it.
Does it work every time? No. Themost negative result I've witnessed is the animal paying little to no attention to it.
I will not use estrus scent before the middle of the pre-rut, but will from that point throughout the season. I prefer a pure non-estrus doe urine with interdigital (pedal) gland added. I formulate my own lure and have found for laying a scent line to the scent post the I.D. works wonders. I use this all year long as I keep mock scrapes going open 12 months.
The key to positive results using lure is using the "correct" lure for the "correct" timeframe you are hunting. It's not magic in the bottle, but, when handled and deployed correctly it does what a lure is designed to do. That would be to lure the animal in, in a calm state without alarm.
Handle the lure properly, don't contaminate the lure handling it without latex gloves, keep it clean approaching your stand site and especially while laying a scentline.
It takes a minimal amount of effort handling and deploying, and will pay dividends when the animal comes in on a string to the scentpost and sets up for the shot.
Find a reputable company that actually knows where the urine base comes from, preferably from their own herd and you'll be dealing with a better quality product than the companies who rely on buying bulk from several different exotic breeders who sell in bulk.
Do your homework before you commit to purchase. Ask questions. You'll know who's talkin' the talk and not walkin' the walk when it comes to lures.
You owe it to yourself to do it. Especially when you spend the time you do in the field. Nothing worse than an animal reacting negatively to the lure you're using and blow the set you've worked so hard for.
Like anything, know what you're using before you use it.
