Whoa, scary! If the hot sauce doesn't deter them, you may have to set up a chicken wire fence around your plants.
I just returned from a Girl Guide training weekend. The catering was supposed to be free from blatant nuts and peanuts... but of course, peanuts and tree nuts made their presence at breakfast and snack: on ice cream bars, on muffins, in cookies. Yes, a good thing I brought all my own food.
The organizer (a doctor) saw the nuts and rushed to find me to warn me not to enter the room with nutty snacks. Two of my friends came to warn me too, both cross with the caterers, and sat with me to make sure I was ok. I was frozen in fear for the next hour as everyone finished their snacks and were touching everything in sight. And we just went over Maslow's triangle of needs that morning... *sigh*
I'm submitting my application for special diets coordinator for the big Girl Guide camp next summer (Guiding Mosaic 2016, if any of your girls wish to attend).
