Bite Blocker does repel ticks as well as DEET. BuzzAway Extreme (not the regular BuzzAway) uses a similar formula. What they fail at is the Asian tiger mosquitoes. Just like any other insect control, nothing works on all species (and if it does, it probably works on humans too ).

I just got some essential oil of lemon eucalyptus (from PlantTherapy, recommended to me as very high quality essential oils) and added some to the bug spray I bought. We don't really have Asian tiger mosquitoes at home (yet, thank goodness, and may they stay away), but there are a few places we go where there are "pockets" of them. So I'll find out whether it works on them, if not I'll bring my picaridin based, toxic "inert" ingredient laden, repellent as backup.
