Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy.
There are some species of snakes that live in the ground or right at the soil surface. These are worm snakes and earth snakes. They will get about 12 inches long when they are full grown. They eat earthworms, slugs, snails and insects that live in the soil, so they can be left alone under the mulch. Wood piles are another great place for snakes to hide. Wood that is used for heating homes should be stacked at least 12 inches off the ground. This will reduce the hiding places for snakes and their prey.
Snakes are usually in an area or structure because there is food there. If you have a snake problem you probably also have an insect or rodent problem to go along with it. Snakes carry a variety of diseases, including salmonella, and can make you sick even without biting you.. Snakes are living in your home or yard because there is attractive habitat and nearby food. Most often they come into homes to den up for the winter and when they do this it can be in alarmingly large numbers.
