My grandmother had a sure fire cure for egg eating snakes. Blow out an egg and fill it with salt. Place back in the nest. Any snake that eats that "loaded" egg will die----problem solved.
We have all kinds of snakes here in Florida. I live in town, in a large subdivision just off a main road and I have seen all sorts of snakes in my yard; black racers, coral snakes, worm snakes, pine, etc. For several years, we had a black racer that sunned on our sidewalk just outside the front door. I nearly broke my neck several times when I didn't look down and would almost step on her.
We would see each other at the same time and she would slither the same way I was trying to go to avoid her. Yes, I know it was a "her" because of the split picky plates and the fact that she showed me her clutch of eggs 3 years in a row. Probably a descendant of hers used to come through our back yard along the fence line - where our chicken run and coop are now located - every afternoon about the same time. When the chicks were babies they would fuss a little, cluster around and look and as they got older they became more curious and after the second time all five of the girls ganged up on the poor snake - it was bleeding in multiple places - it has changed its path. It still comes through the yard at the same time - but along the house and deck where the girls can't get it. I would never kill it as there are a few empty houses in our neighborhood and we have seen and trapped a number of rats and black racers eat said rats. DH is terrified of
snakes so calls me to identify and "take care of" the offender.
