BS! The stink bugs were invasive and tried this new place and the normal climate did them in. Also, after a few years, the local food chain figured out how to eat them. Birds don’t just start eating strange things, they slowly decide that new things are edible after assuming first that the bugs might be poisonous. Yes, discrimination as a survival tool!
Amazing how the climate hoaxers will latch on to anything and shape it to their needs.
Our Cane Corso Italian Mastiff absolutely LOVES to eat the damned things. She found a pile (like a double handful) in between two pillows on the Patio furniture and just stood there crunching away.
I asked Her if She wanted any salt, chocolate sauce or anything else, She just kept on eating them till they were gone.
Any that make it in the house get chased down and eaten.
