Mosquito Repellant from Garden - Chaste Berry tincture

Mosquitoes have been fierce this year. Did some digging, came across this:

Some chaste berries have been picked from the hedge-row, smashed, and soaked in rum. Preliminary results are promising.

Soaked in rum?  Perhaps it is the bat on the Bacardi label that scares them off!  LOL

LOL - bats crazy, J.P.!

Here's another study that showed that yarrow (Achillea millefolium) has repellant properties. I also read about thyme, and have some I just harvested, and have read multiple reports of white vinegar being a repellant (and that could be a base, cheaper than alcohol).

Also have an abundance of lemon grass, which has shown to be repellant, that will go in the mix and sweeten it up for human noses.

Anyone else got ideas for what to use to use in concoctions to keep the flying tigers at bay?

  I've been using pennyroyal from the garden, tinctured in vodka, then diluted in a spray bottle, for years with success against all biters. Needs reapplying once an hour or so, but as a bonus it smells nice and is cooling. I always spray my hat and clothes, too.
  And when we owned a camp near a swamp, I accidentally discovered that eating tons of pickled ginger kept them from biting. May have had something to do with the vinegar?
