Chipmunks. I’m sorry to hear this.

What was the mode of the roses‘ death?

I have experience with an sound-wave emitting ”spike“ marketed to deter groundhogs. Within a few hours of putting it in the garden, a groundhog responded by sitting on it while decimating a Stokes aster. This was several years ago. We didn’t have chipmunks here back then. I would not have wanted to deter them.

Melissa: See below link of the 12 SPIKY air-pots that I bought, thanks to Hoang Ton setting an example with his amazing Austin roses in air-pots. Chipmunks used to climb up to my short plastic or styrofoam pots to eat the buds off from my roses, but THEY CANNOT climb up to tall & spiky air-pots. The spikes are sharp and hard to chipmunks to climb up, see below link of my 12 air-pots:
