My wife warns that it is incorrect to kill snakes that have taken residence along the margins of our koi pond, but still she wants to be rid of them, by violence or persuasion, she doesn’t care. I remain conflicted. The Northern Brown water snakes are a bit of a nuisance, causing me to be overly cautious weeding stilt grass that invades clumps of irises where the snakes reside. Certainly, there’s no issue with the occasional fish they snatch since there are another hundred or more, but there is an uneasiness around the pond that is less than ideal.
Generally, I prefer to let nature take its course with minimal interference. This constructed garden attracts diverse wildlife, which is appreciated, so if Japanese beetles or caterpillars munch a few leaves, there are plenty more. While no pesticides are sprayed, I spray a repellent to discourage deer, though this harms no creature except deer burn a few additional calories moving on to the next property.
Eventually, I’ll get around to pulling the stilt grass, but probably long after it’s dropped seeds for the next crop. I’ll do some stomping around before I do much reaching into the iris clumps, so perhaps this will be enough of a warning that the snakes will go off to the other side of the pond. If I was as brave as I claim, I’d snatch them up and relocate them down the road, but that’s a bit much for me. Mostly, I fear being startled and falling head first into the pond. Not that there’s much danger involved, but I’d prefer to stay upright and dry.
