It is spelled Permanone. Permanoneand Duranon are simply marketing names for the exact same insecticide. Let me say that again. It is an insecticide; not a repellent, even though Sawyer and Repel advertise them as a repellent. Deet is a repellent.

What you want to look for is the active ingredient in both which is PERMETHRIN. Permethrin uses clothing as the delivery system for it to work as an insecticide. So you have to put it on until it is soaking wet and then dries. You can't just spray it on and walk into the field and expect it to work like Deet. Yes, Deet smells, Permethrin smells very little to not at all when dry. Both have pro's and cons', but you have to know what they do and how they do it for either of them to be effective.

So what does this mean? Permethrin products will kill insects when they come in contact with the delivery system. Deet will repel insects, but not kill them. The most effective method is to use both. Does it spook deer to use Deet? Some say yes, some say no. I don't know myself, but if I had the problem and was worried about the smell of Deet, I would use permethrin impregnated clothing tucked into rubber boots tightly.
