doe in heat lure

[mmwb]

Sounds good, but not sure on the pheromones. I don't think it is some much that they evaporate into the air, but that they break down on a molecular level (short half life) very quickly. If this is the case, than isolation from the atmosphese is not going to change that. Also, in the process of getting the urine out of the bottle, you are going to create a vacuum. At some point you'll have to introduce some air just to get more of the stuff out! It may be a fine product, I just question if the pheromones are going to be any more of a factor after a couple of days, than in other urines taken while the doe was in heat.
