Yo I need some advice for a friend that has Water Moccasins in her pond. I have not seen the pond but know it has not been treated with anything for years if ever treated. My first advice to her was to weed control everything in and around the pound to remove any habitat that helped the Water Moccasins. I am also told that Sulfur helps to repel all snakes. Her Main concern is her horses drink from this Pond. She does not want to poison the pond in any way to hurt the drinking quality of the water. She would like to use this pond with her small boat. BTW I have contacted the County Extension Agent about this problem with little success so far. The Agent has send requests for help to our State Land Grant University with no results so far. I am sure there has got to be a way to either trap, repel or kill these creatures. However Gators continue to be a problem in the city residential ponds in my area. Snakes are becoming less a problem due to Fire Ants that eat their eggs. However Water Moccasins give live birth and no eggs. BTW This is for a friend and I am just trying to help her out, not make money on the deal.
