Fighting mosquitos indoor
Not sure how well it works (haven't had a chance to use them, yet) but the Off Clip-on Mosquito Repellent seems quite convenient.  You can clip them on and keep mosquitoes away while you work in the yard, this way you can't mistakenly wonder out of the protected range of candles, and you don't have to spray chemicals on your skin (that wear off as you sweat anyway).

WebMD says 


  "Mosquito traps, a relatively new
  product, may be the answer. They work
  by emitting substances that biting
  mosquitoes find attractive -- such as
  carbon dioxide, heat, moisture, and
  other mosquito-friendly byproducts.
  They attract, then trap or kill female
  mosquitoes. When placed strategically
  near breeding spots, "they have
  knocked [mosquito] populations down,""


Placing one of these Mega-Catch™ Alpha Mosquito Traps a little way from your deck or patio, should lure the mosquitoes away from you and into the trap.
