Yes, you can use Counter spells to trigger this card's ability when an opponent Transforms into a card from field/hand. Do note that due to the "once per chain" rule, you can only cast/use one Counter in response to their Transform, so if the card Transformed into has more than 3000 defense, or 6000 if you cast The Hot Zone, it won't be destroyed. You have other opportunities to cast Counter spells, such as; the opponent casting any card, using any [Act] abilities, or automatic abilities, and start and end of each phase, though.
