How to remove blank space on the menu bar?

For some reason I have a blank space on my menubar, It doesn't happen on my second screen, and when i click it disappears but appears in the other screen and so forth.

I haven't done anything to the system like trying to remove the spotlight icon or that sort of thing. I have OS X 10.9.4

I've tried removing all other apple icons and this happens:

When I activate istat menu, the issue goes away temporarily but I'd rather not use istat forever.

Are there any other solutions to this?

Solution 1:

Restart your menubar

This might be due to some error within the placements of the icons in your menubar. You can restart your menubar and your icons will 'reload' and settle correctly.

Run the following in Terminal to reload the menubar:

killall -KILL SystemUIServer

Solution 2:

it was LittleSnitch, even though it had it "show status in menu bar" disabled, on one screen it will always show that empty space.

Solution 3:

Some applications (like Google drive) will reserve the space to the right of it for messages.
