Outdoor fans do help to keep bugs away.
When bugs and insects are bugging you and pestering you then using fans such as barrel fans, oscillating fans or even a box fan can help to keep bugs and insects away.
The more powerful the fan the better job it will do at keeping bugs and other insects and including mosquitoes away from you.
I use a barrel fan to keep bugs and mosquitoes away from me outside.
On the patio or porch I use a box fan and oscillating fan which not only keeps me cool but also keeps the mosquitoes and other insects away from me.
The bugs cannot fly properly in the wind of the fan so they get blown away.
They still try to come near you but the fan works to blow them away.
Some bugs may get annoyed themselves and then fly off somewhere else.
Using bug zappers and even co2 traps can also help to keep bugs away including mosquitoes.
Citronella candles and Tiki Torches are also good to keep bugs away.
Another way to keep bugs away is to use a fire pit and have a smoky fire as the bugs hate the smoke and will stay away.
