Field & Stream's mid-south Rut Reporter Will Brantly talks about how to best use estrous scent to draw deer in close. Consider a scent trail, which can channel bucks to your stand, their head down, focusing on the ground rather than the hunter above.
Tea candles in a coffee can below a secondary can. One can contains syrup, the other bacon grease. The candles burn for about 4 hours and the wind has never blown them out.
Note these pots actually have too much grease and syrup in them (it had been a couple years since I used them). Use half as much (about 1/2"), to allow the full amount of scent possible to get into the air as it slow cooks. When you can see the wisps of smoke coming out of the cooker...it's perfect.
DYI Homemade Scent Blocker :
To make a homemade scent blocker, mix 1 quart of distilled water, 1/2 cup of baking soda, 1 quart of 3 percent hydrogen peroxide and 1 ounce of unscented body wash. Mix until the baking soda dissolves. The homemade scent blocker will give off some gases.
Bottling the Mixture:
Do not tighten the lids on the spray bottle or jug---leave them slightly unscrewed so the gases in the mixture can escape. Let the homemade scent bottler stand in a dark place for three days.
Applying the Scent Blocker:
Use the homemade scent blocker as a soap to wash your body and hair.
Do not apply scented deodorant after you are done showering or bathing. Dry your body and hair with a clean towel that was not washed in scented detergent. Spritz your body and hair with the scent blocker. Spray your clothes, boots and other gear. Carry the spray bottle with you to the forest or other hunting area and spray yourself again after you exit your vehicle. Avoid getting the scent blocker in your eyes and mouth.
