Wow, those are hunger chipmunks!!
Mine just make tunnel in my gardens, veggie and flower, and eat the plants from underneath!!
I also hate powdery mildew!! I have NO luck with squash, cucumbers, or melons. I get one or two, then the mildew hits and that’s the end. Keep rotating between raised beds, but that doesn’t help.
Hungry? Not likely. With all the birdseed they eat it is a wonder they aren't too fat to move. They are just evil.
If the cats are inside, the chipmunks parade up & down in front of the window to tease them.
If the cats are out, the chipmunks are nowhere to be seen, but I worry about the cats getting run over.
