We live in North Texas, and the pool was a new build and finally we are enjoying the pool this month's after all the rain...... Anyhow, I have been catching 3 small snakes, 10 inches long, around the shady part of the infinity spa, the water channel portion. Is there a reason to be concerned? The snakes are in the water channels where the infinity spa flows into.... And I catch them when I just scoop the leaves and whatever inside of those channel. The water chemistry is good, and the pool is clear. Do I have a snake problems that needs attention?
