Hi. Do pheromones expire after a while and become uneffective?
If yes, how long does it take? I have some which are 1 year old and I wonder if they are still useable or not.
Depends what they are and how you treated them.
Are they alcohol based or oil based ?
Did you store them in a cool dry dark place ?
1 year should be fine for both oil and alcohol. In fact stored correctly alcohol should last years and years. Oil tend to break down or separate after a few years easier.

Hi, they are alcohol based.
What do you mean with cool place? A fridge? I just stored them at room temp.
By cool I am mean not in the sun, the car or any other place that can heat up beyond the normal everyday temps you get in the shade.
Room temp is fine.

Ok, thanks
