Scares deer, but blood meal attracts racoons and skunks.
Really? I had a skunk underneath the house this winter. But I haven't put out blood meal in a few years. I ran the skunk off with Rodent Repellent ultrasonic frequencies on youtube cranked up to about 3 times the normal listening volume.
Hey that might be a strategy for Freya. String the dock with speakers and play repellent frequencies 24/7. We can't hear them. But a Walrus might.
