Otters are cute. What's not cute is the mess they leave when the come into my boathouse and use the deck (and anything laying on it) as a latrine. It smells like fish and urine. The otters must go.
Trapping or poisoning is not an option. I don't have a dog and don't plan to get one. I'm only at my cabin (with the boathouse) 2 weekends or so during the month.
Is there something I can put in the boathouse that will keep these cute pests from using my boathouse as an outhouse?
