Finding a lizard scurrying across your living room wall can trigger two very different reactions: mild panic or quiet curiosity. While some see it as a pest, others believe it carries deep cultural, spiritual, and even ecological significance. Across the world, the humble house lizard is not just another reptile—it’s a symbol, a messenger, and in some cases, even a protector.
Cultural and Spiritual Beliefs
1. In Indian Tradition
In many parts of India, lizards are closely tied to Vastu Shastra (the ancient science of architecture) and astrology. According to the Gauli Shastra—a traditional lizard astrology system—where a lizard falls on a person’s body can signify upcoming good or bad events. For example, a lizard appearing in your home can be interpreted as a sign of change, often associated with transformation and growth.
2. In Southeast Asian Beliefs
In countries like Thailand and the Philippines, a lizard’s call or sudden appearance can be considered a message from the spirit world. Depending on the timing, it might be a sign to avoid a certain action or a warning of unexpected visitors.
3. In African Folklore
Certain African tribes see a lizard’s visit as a sign of prosperity and protection. It’s believed that lizards bring luck to the household and ward off evil spirits, especially when they linger inside the home.
Scientific and Ecological Perspective
While folklore adds charm to the idea of lizards as messengers, science offers a more grounded explanation:
- Pest control – House geckos feed on mosquitoes, flies, ants, and cockroaches, making them natural allies in keeping your home pest-free.
- Temperature changes – Lizards are cold-blooded animals that may seek warmth indoors when outside temperatures drop, or shade and safety when it’s too hot.
- Food availability – If you see more lizards than usual, it may mean there’s an increase in insect activity in your home.
Facts and Studies
- Pest Control Benefit – A study published in the Journal of Pest Science (2016) found that house geckos (Hemidactylus frenatus) significantly reduce the presence of disease-carrying insects in urban homes.
- Indicator Species – Environmental scientists classify lizards as “bioindicators.” According to a 2019 biodiversity study, sudden changes in their presence indoors can indicate shifts in insect populations or environmental conditions nearby.
- Urban Adaptation – Research from the Herpetological Conservation and Biology Journal (2021) shows that some lizard species thrive in human dwellings because our homes provide stable temperatures and abundant food sources.
