Spiders use Earth's electric field to travel "go ballooning"

Spiders commute, they "go ballooning" with the electrostatic force reaction between their spider silk and Earth's electric field.

"Many spiders balloon using multiple strands of silk that splay out in a fan-like shape, which suggests that there must be a repelling electrostatic force involved," explains lead researcher Dr. Erica Morley, an expert in sensory biophysics.
The solution to the mystery could lie in the Atmospheric Potential Gradient (APG), a global electric circuit that is always present in the atmosphere. APGs and the electric fields (e-fields) surrounding all matter can be detected by insects. For example, bumblebees can detect e-fields arising between themselves and flowers, and honeybees can use their charge to communicate with the hive.
In their study, the findings of which appear today in the journal Current Biology, Bristol's researchers exposed Linyphiid spiders to lab-controlled e-fields that were quantitatively equivalent to those found in the atmosphere. They noticed that switching the e-field on and off caused the spider to move upwards (on) or downwards (off), proving that spiders can become airborne in the absence of wind when subjected to electric fields.

"electric fields (e-fields) surrounding all matter can be detected by insects" ... This might be why it is so tricky to swat a fly with your hand.

That's why I take out flies with a stealthy rubber band. I can even shoot them out of the air. (The flying rubber band is like a shotgun blast.) That is, if the cat doesn't get them first.
