hello, we use Deer Stopper on our gardens to keep deer from foraging. Last fall we put our unused portion in the basement which we do every year if there are any leftovers. This April, probably later month and now all the plants I sprayed, including my wonderful native garden have died! I am heartbroken. My question is..... will these plants come back or are they a goner? The ingredients in Deer Stopper are only egg, rosemary oil and mint oil.
