Scarabs travel in large swarms through narrow passages, and their loud skittering can be heard from far off. They will pause and embed themselves in the rock when Samus comes close. A single shot from any weapon will dispatch them, and the blast will often take out several at a time. However, don't get too close, or they will explode. A single Scarab will deal just a tiny amount of damage, but if you try to bulldoze through them, be prepared to lose a full Energy Tank.
