Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results

Why do you have controls in an experiment?
The controls shows the normal state of affairs, so as to allow a comparison with the experiment results, and to help ascertain that the results obtained were due to the factors tested in the experiment, and not a natural occurence/incidence. Having controls in an experiment can thus be said to validate the experiment itself.
