What an educational post! I've never heard of Bacillus thuringiensis (Bt), but it's kinda freaky how it works. 😯 I hope it gets rid of the Squash Beetles that are ruining your pumpkin plants — although they're cute, so sad they have to be destructive. I, too, would be curious about ruins like that! Good for you, looking them up to see what they are! Too bad they don't have an historic marker somewhere nearby. 😕 That's awesome that the Activities Director wants you to perform again! You bring so much joy and many smiles when you do that! 😊
