If you’ve ever lived in a tropical or subtropical region, chances are you’ve encountered those small, seemingly harmless creatures that scuttle across your walls – wall geckos. These unassuming house guests often provoke questions and even concerns among homeowners. Are wall geckos dangerous? Do they pose any risks to humans or our homes? In this blog post, we will unravel the mystery of the common house lizard and explore whether they are truly a cause for worry.

Meet the Common House Gecko

Wall geckos, scientifically known as Hemidactylus frenatus, are a type of gecko that has adapted to living in and around human dwellings. They are typically small in size, measuring about 4-5 inches in length, with a distinctive appearance characterized by their beige or light brown coloration and rows of dark spots running down their bodies.

Geckos are known for their remarkable climbing abilities, thanks to the adhesive pads on their feet, which allow them to cling to vertical surfaces with ease. They are also known for their distinctive vocalizations, often heard as chirping or clicking sounds, particularly during the nighttime.

Are Wall Geckos Dangerous to Humans?

The short answer is no, wall geckos are not dangerous to humans. In fact, they are generally considered beneficial housemates for several reasons:

  1. Pest Control: Wall geckos are voracious insect hunters. They feed on a wide range of pests, including mosquitoes, flies, ants, and cockroaches. Having geckos in your home can help naturally reduce the populations of these nuisance insects.
  2. Harmless to Humans: Wall geckos are not venomous, and they do not bite humans. They are quite skittish and will usually flee from human contact rather than confront it.
  3. Disease Control: By preying on disease-carrying insects like mosquitoes, geckos indirectly contribute to disease prevention in the household.
  4. Low Maintenance: Geckos require no special care or feeding from homeowners. They are self-sufficient and thrive in their natural habitat.
  5. Cultural Significance: In some cultures, geckos are considered symbols of good luck or house protectors, further highlighting their positive reputation.

However, it’s essential to note that while geckos are generally harmless, some people may find their presence unsettling or unpleasant due to their appearance or vocalizations.

Are Wall Geckos Harmful to Homes?

Wall geckos are not known to cause any direct harm to homes. They do not chew on electrical wires, damage structures, or carry out destructive behaviors. They simply coexist within the household environment, hunting for insects and maintaining a low profile.

Tips for Coexisting with Wall Geckos

If you find the presence of wall geckos bothersome, consider these tips for peacefully coexisting with them:

  1. Maintain Good Hygiene: Keep your home clean and free of food debris to discourage insects that attract geckos.
  2. Use Screens: Install screens on windows and doors to prevent insects from entering your home while allowing geckos to exit if they wish.
  3. Natural Deterrents: Some natural repellents, like garlic or citrus scents, may discourage geckos from frequenting certain areas.
  4. Gentle Relocation: If you feel compelled to remove a gecko from your living space, do so gently using a piece of cardboard or similar tool.


In conclusion, wall geckos are generally not dangerous to humans or homes. They play a vital role in pest control, helping to keep your living space insect-free. Instead of viewing them as nuisances, consider them as eco-friendly, natural exterminators that share your living environment. If you can learn to coexist with these small reptiles, you may find that they bring more benefits than drawbacks to your home. So, the next time you see a wall gecko scurrying across your wall, you can rest assured that it’s a helpful houseguest, not a dangerous intruder.
