While in Kerala last month I happened to briefly visit a pineapple farm. The rows and rows of the plant was a lovely sight. Almost all of them had mature fruits ready for plucking. In fact, the harvesting was due a week later.
One strange thing I noticed was long pieces of old fishing nets strewn on the ground at several places on the plantation. The owner of the farm explained to me that the nets were cheap and efficient snake traps. The reptiles get entangled in the mesh as they crawl along.
He went on to explain that the method offered effective protection against snakes. He has arrangements for collecting discarded nets from fishermen; they cost next to nothing. According to him often, in the mornings, snakes are found trapped in the net.
I think this line of defense against reptiles is a good idea. Perhaps it is already well known, but is new information to me
I have heard it said that snakes shy away from places where there are tulasi (basil) plants but could not find any authority to rely on. However, in the United States there is a product named Snake Away. It is a repellent which is claimed to keep reptiles away by its odor. The University of Florida has, reportedly, tested and certified it under the EPA Testing & Protocol. Perhaps basil has similar properties.
There is a useful FDA sponsored article on snakebites by John Henkel titled For Goodness Snakes. You can download it at:
