I did try rubbing some crushed powder to the bite, but could not notice any effect before I got impatient. Ketamine on my tongue has an instant numbing effect, but to my knowledge nothing transdermaly. I took it insufflated, the short duration of action and general anesthesia makes it decently practical. (Of course it sounds pretty silly to recommend Ketamine for a small everyday itch. But that's what I had on hand, and I happen to dislike mosquitos with a very particular intensity =] )
