So many people have a terror of snakes, any snakes. However, each year many more snakes are killed by humans than humans by snakes. There are precautions you can take, such as wearing sturdy boots while walking through tall grass, treading heavily, and being alert. Snakes do not have ears, but sense movement by "feel". Therefore, if you walk heavily they know you are coming and flee. Snakes' diets are mainly rodents. No snakes equals a rise in the rodent population. Welcome to our house, mousy! We killed that nasty black snake that ate your cousin Ralph. The vast majority of snakes are non-venomous, and those that are often "dry bite" meaning they do not inject venom when biting. Building up venom takes time and effort, and there is no reason to waste it on a rat. Snakes are not slimy, but are dry and oh, so muscular. You can tell I respect and even like snakes. They are useful, quiet, and rather pretty.
