Bests & Worsts Reviews from Amazon

This item is advertised as a "mosquito repellent device". Imagine my surprise when I read the fine print on the box---it is actually a heat-release vaporizer dispensing the insecticide Allethrin. That is a synthetic pyrethrin-type insecticide which scrambles nerve signals in insects--causing them to fall down twitching and not bite you. This is NOT a "repellent", this is an insect killer, although its package uses the word "repellent" over and over. I would not have knowingly bought an insecticide fogger. The package has numerous warnings that do not appear on the Amazon sales page, such as "do not contaminate water, food or feed" by use or disposal of the ThermaCell; "harmful if inhaled", and "do not breathe vapors" (good luck avoiding THAT around a vaporizer appliance!) The package also states that the insecticide is toxic to fish and other aquatic life (probably not suitable for use near a garden pond.) Finally, a Wikipedia search revealed that the pyrethrin-type insecticides are highly toxic to cats. Since I bought this thing to ward off mosquitoes on a patio we enjoy with our three cats, it's absolutely NOT acceptable. Sadly, as a butane-burning appliance, it is also NOT RETURNABLE to Amazon, so please, BUYER BEWARE.
