Geckos are generally harmless to humans—they don’t bite, aren’t venomous, and actually help by eating insects. Still, having them inside your home can feel uncomfortable. The good news is you can discourage them without harming them.
1. Remove Their Food Source
Geckos are attracted to insects like mosquitoes and flies. If you reduce indoor bugs—by keeping food covered, cleaning regularly, and avoiding standing water—you make your home less appealing to them.
2. Seal Entry Points
These small reptiles can slip through cracks, gaps around windows, or under doors. Check your walls, install door sweeps, and seal openings with caulk or mesh to prevent them from entering.
3. Reduce Light That Attracts Insects
Outdoor lights often attract insects, which in turn attract geckos. Switching to warm-colored or less intense lighting near entrances can help reduce this chain effect.
4. Use Natural Repellents
Some people find that strong smells like garlic, onion, or certain essential oils (like peppermint) help keep geckos away. While not scientifically guaranteed, they can be worth trying as a harmless deterrent.
5. Keep Walls and Corners Clean
Geckos like quiet, undisturbed areas. Regularly cleaning corners, behind furniture, and storage areas removes hiding spots and makes your home less inviting.
Final Thought
Geckos may be unsettling, but they’re not dangerous. With a few simple steps—mainly reducing insects and sealing your home—you can keep them out effectively and humanely.
