If you are moving back and forth form one activity to another than you have to destroy the banner, always destroy banner before loading a new banner,

so while going form activity A to B destroy banner in A than go to B and load the in B.

  IronSource.destroyBanner(banner);

and while coming back form B to A than also destroy in B and again reload the banner in A

you can use onBackPressed to destroy the banner

    public void onBackPressed() {
        super.onBackPressed();
        IronSource.destroyBanner(banner);
        finish();
    }

If there is a backbutton on nav bar

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {
            IronSource.destroyBanner(banner);
            finish();
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

this may vary in your case android.R.id.home
