I was returning from Texas one night and made it into Louisiana around 1 am before I got too tired to continue.
So I found a shopping mall and parked near the middle away from any trees or brush.
It was warm so I cracked a few windows to get some fresh air and fell immediately to sleep.
I was awakened about an hour after I fell asleep to buzzing in my ears and burning all over.
To my shock and horror I was covered with what must have been 5,000 mosquitoes ! I was covered and jumped up frantically
beating them away and jumped out of the van trying to get them off. Clouds of them!
I left immediately and then noticed I was swelling from head to toe from hundreds if not thousands of mosquito bites.
I had big red horribly itching whelps covering me completely, face, feet, legs, arms, ears....every square inch.
I didn't stop again and drove through the night to my destination in North Georgia.
It took a week to recover and it was miserable.
I will try anything and everything including the link in the OP after that.
Had I known I would have left the motor running and used the AC.
Gawd I hate those nasty creatures.
