No, not really. The sticks will be too big, and the diet will not meet the betta's nutritional needs. It will not harm him, and can be fed short term, but you should buy a betta diet as well, and feed this as an occasional treat, at best.
Bettas are very picky eaters. Some love flakes, some want granules. In the wild, they eat mostly vegetation and insect larvae. Bettas have very special intestinal systems, and should not be overfed. It is also best to give them a diet designed especially for them, because of this.
