Understanding Their Behavior

By understanding the general behavior of snakes and what attracts or repels them, you can effectively control their presence in and around your property.

Snakes are attracted to warm, dark, and moist environments. Since basements and attics are the two places around your property that meet all the ticks, they find shelter and prey.

Snakes have a keen sense of smell and can detect vibrations. This makes them highly sensitive to their surroundings.

The most dominant sense they possess is the sense of smell. It allows them to locate food and avoid danger. This sense of smell can be the main factor that leads them to your house if they can sniff out a steady food source, meaning rodents.

Some folks might want to take this as a hint that they may have a rodent infestation on their property to have attracted snakes.

Snakes hate the smell of vinegar and ammonia. It overwhelms their keen sense of smell.
