This is virtually the question many Nigerians ask after a naval officer was bitten and killed by a snake when she went to use the toilet.
Basically, snakes as well as other reptiles and amphibians such as frogs get access to toilets through openings and cracks from sock-away pit and control chambers.
They then climb their way up and surface in the toilet water closet system.
People living in ground floors are more likely to have snakes get into their toilets, as well as those living in areas that have old and structurally damaged sock-aways.
How to keep snakes from your toilets:
A sure way to keep snakes as well as other reptiles from your toilets is to flush your toilet with a mixture of about 2 to 4 liters of kerosinme and 100 Naira salt.
Snakes and other reptiles cannot survive in a such environment and will definitely flee.
