You could use something like the switch implemented in this
mw ex project attached.

The slider serves as the switch when the user clicks on the
spacebar and the slider is on 0, then the turtle is activated
and the slider is switched to 1.

Then when slider is in 1, the turtle is deactivated and the
slider is switched to 0 again.

The code in that project is:

to start
forever [
 if 32 = ascii readchar [
  ifelse 0 = on-off 
   [t1, clickon]
   [t1, clickoff]
  seton-off 1 - on-off
