I'm the guy that mosquitoes love. If I'm around, you don't need any repellents because they will swarm me and leave you alone.
I went camping this weekend and covered myself head to toe in OFF! Deep Woods for Sportsmen, which is supposed to be the best stuff, had a citronella candle, and a few coil repellents, and still ended up covered in bites, while those I went with who used the same stuff did not get one bite.
I've read that catnip oil is supposed to be very effective. Has anyone used it? Does anyone know of any good repellents?
