Most of these Tantras speaks about specific results, depending upon the exact place of the body on which the House Lizard has fallen and these body-parts are further sub-divided into exact locations. For example the face is sub-divided into the fore-head, cheeks, ears, nose lips, chin and eyes and the end results of the falling of the House Lizard depends upon the specific location, some locations are considered to be auspicious where others inauspicious.
There are also diverse opinions and writings in various texts as to the end fruits of the falling of the House Lizards on these locations.
Therefore, in my opinion it is best to ignore this incident, if ever it happens to you or someone close to you. There are of-course many people who will cling on to such an incident and it will prey on their minds and leave them feeling either scared or depressed or both, for these people, I will explain a simple remedy, which is specific to the incident of the Lizard falling o the body.
It it ever happens to you, you should have a bath wearing the same clothes you were wearing when the House Lizard fell on your body.
Then, you must, wear fresh clothes and light a Ghee Diya before an idol or photograph of Shiva, either at home or in a Shivalaya.
Then, finally you must chant the Shiva Mantra – Om Namah Shivaya- ॐ नमः शिवाय, 1100 times. This is said to remove forever the Dosha resulting from the falling of the Chipkali on any part of your body.
Note- This Hindu Paranormal Remedy is of-course for those people who believe that something bad will happen to them as a result of the falling of the House Lizard on their body, others, who do not feel so strongly can simply ignore the incident and think nothing about it.
