In NM we called the ones out there G nats and used skin so soft on bare skin. Applied thick if they landed they died.
I bug bomb my garages when needed. Takes care of spiders and flys at the same time.
Bug bombs? I just use some common black powder sprinkled around the inside of the garage to take care of the creepy-crawlers, it works good, just remember to start the car, with the exhaust pointing out the door.
The dag-gone spiders will build a web overnight on the door/mirror of my truck, sitting outside in the driveway beside the garage, but none inside.
