There is nothing wrong with using last years bug spray! We had our Refill Jug full of 2020 mix and we decided to put them in our squatty amber bottles. They fill 1.7 fl oz so it's a bit short of the typical spray.
We decided to go ahead and put them on sale for you in case you need extra spray for your child nature bags, your purse, or an extra bottle for your car!
Hurry before they are gone as there is only a limited amount available!
