I've used the Sawyer permethrin and haven't had any bites, so I think it
works well.

I just received this concentrated permethrin:

A guy on Whiteblaze had researched concentrated permethrin and found that
most of them had a lingering scent, but found that the concentrated
permethrin above was an exception.

I can't really say how well it works since I haven't had a tick bite with
either treated or untreated clothing, and I haven't tested the new stuff.
