I'm wondering what you did with the snake. did you kill it? I guess its just right if you did. i mean, you cant repel that any more. it already knew where to get food fo it will just come back for more.Oh no! Have you tried Bonide snake repellent? I personally have not used it yet but I've asked quite a few people who all say it works great. You can get it at TSC, amazon or ace hardware!
