Do you ever see a spider darting across your living room floor, or chilling in the corner of your ceiling, and jump? For most people, spiders are unwanted house guests who are very useful in controlling other pests, but their presence usually comes with an uncomfortable disposition. But did you know that there is a natural and efficient way to avoid spiders in your house?
Why Do Spiders Have a Response to Odors?
The Science of Spider Behavior
Spiders don’t have noses like humans, but they are extremely sensitive to their surroundings. Rather than smelling through nasal passages, they use special sensory organs on their legs and body. These organs sense vibrations, chemicals and scents in the air to guide spiders through their surroundings and help them find prey.”
Some odors are so strong or pungent that they can overwhelm those sensory systems, making them virtually disoriented. The odor of these oils is enough to make it unappealing to be in the area of where you apply these oils.
Common Spider Habits in Homes
Before you get into how to repel spiders, it’s important to know what the most common culprits may be for them entering your home in the first place. Spiders are attracted to areas that provide:
- Shelter: Basement, attic and closet are hideaways, dark, quiet places.
- Food: Spiders eat insects, so if you have bugs in your house, spiders will probably move in too.
- Moisture: Certain species of spiders like low-lying, damp areas such as a bathroom or kitchen.
By eliminating these conditions, and using odorous smells they hate, you can decrease the chances of meeting spiders in your home.

Myths and Facts About Spider Deterrents
Do Conkers Really Work?
