Review (5/5): Works Super Fast!
My landlord hired a new pest control guy to service our 100 year old wood frame apartment building. The pest control guy decided to keep critters out of the crawlspace under the building using mothballs. This is stupid (not to mention illegal) as mothballs are a pesticide with very strict usage requirements (read the packaging) and can contaminate groundwater and soil for years. The odor was coming through the cracks in our wooden floor but mostly through the air conditioning vents (I guess he threw a few mothballs in there for good measure). My landlord and I tried EVERYTHING to get rid of the smell, we had the vents professionally cleaned, I sprayed a few bottles of fabreze into the AC intake. I used a professional "odor bomb" (like a bug bomb but with deodorant), candles, sprays, baking soda, everything, but nothing worked.
Then, a Google search directed me to Smelleze's website. I bought a 2lb can and sprinkled a little into each vent in the house and into the intake. Within an hour the smell was almost gone - within a week it was gone completely! This stuff really works and fast. I probably spent over $100 trying to get rid of the odor and this stuff finally did it, i'm shocked that they don't sell it in retail stores(right next to the moth balls).
On a personal note, it is astounding to me that anyone living in the 21st century would use mothballs for anything; they're toxic, they smell like death, they linger and there are effective alternatives that don't make you want to leave your house as much as the pests they get rid of.
