Yes, and they can fly as well as stick to vertical surfaces. Just imagine if they were OUR size...

The structure allows bacteria to stick to surfaces is FLAGELLA
The material is tacky and sticks to the surfaces it contacts.
It doesn't wet surfaces. It doesn't stick to glass.
Surface tension
The majority of walking stick-type insects do not migrate. The majority, instead, hibernate during colder seasons. They also have a short lifespan,
It depends if you want it to fly up or down. At take off you would pull the stick
It sticks best to smooth and dry surfaces.
Water molecules are both cohesive and adhesive: they can stick together or stick to other surfaces.
The short answer is that the pilot uses a stick which, combined with the rudder pedals, tells a computer what he wants to do. The software then determines the appropriate way to do that by sending commands to the control surfaces and engines. That part is what's called 'fly by wire'.
