Icaridin generally doesn't last as long as DEET though. For fans, I have seen people make mosquito traps by attaching a bug net to a fan, sometimes combined with a CO2 generator as bait. I don't know how effective it is in practice. What we do sometimes is to put a fan under the table, it helps a little against low flying mosquitoes, definitely not as effective as DEET though.
