Is Naphthalene crystals in my ceiling dangerous to my health.?

Question

Can anyone please tell me the risks of having mass amounts of Naphthalene crystals scattered throughout my ceiling, even sitting on exhaust fan covers in the kitchen and bathroom. The owner has just done this hoping to deter possoms but now my house stinks like mothballs. Is it toxic to inhale? Does it react to heat(heater in winter)? Is it a fire risk? Thanks

Answer 1

naphalene is fine, but if its on every air passage in your living space, it may be dangerous. dun worry about fire hazards though, naphalene sublimes on heating, so unless ur heating it in a glass vessel, ur fine

Answer 2

Its bad for you.  In some states it is considered a carcinogen and that stuff permeates everything you own.  Eventually all your clothing, carpeting and walls will smell like mothballs.
