Product review (1 stars): Worst product I have ever purchased.
I cannot believe anyone would continue using this in their humidifier. It smell horrendous. Burns my eyes and nose and gives me constant headache. Seriously, this is poisonous insecticide. Read the label before purchasing. You have to bring this to the EPA to dispose off. There are all kinds of warnings. Dangerous to humans and domestic pets! Nothing but poison and you're putting this in a humidifier? Worst product I have every purchased.
