Do I let go of a wild house gecko?

If the wild house gecko is not causing any harm and is living peacefully in your home, you might consider letting it stay, as they can help control insect populations. However, if it poses a health risk or you simply prefer not to have it inside, you can safely catch it and release it outside, ideally in a suitable habitat. Make sure to release it far enough from your home to prevent it from returning. Always handle the gecko gently to avoid harming it.
