Locust Swarm is a basic common zombie trick card in Plants vs. Zombies Heroes and a member of the Beastly class. It costs 5 to play, and its ability instantly destroys a selected plant on the field. Its plant counterpart is Squash.
It is based on a swarm of locusts, species of short-horned grasshoppers in the family Acrididae which possess both a solitary phase and a swarming phase.
Its description is a reference to how locust swarms are a major threat to plants. It might also reference the fact that the collective noun for locusts is "a plague," and that one of the Ten Plagues of Egypt was a plague of locusts. It may also be a reference to Mercutio's last words in Romeo and Juliet: "A plague upon both your houses!"

Locust Swarm does not have any restrictions on what it can destroy, and it is reliable (unlike B-flat). But on the downside, Locust Swarm is very expensive. It is also outclassed by many other instant-kills in most situations, even if they have limits. Locust Swarm also cannot affect Untrickable plants. Still, even if you consider the negatives, Locust Swarm is a great card to have for many Beastly decks nonetheless.
Locust Swarm is also a pet trick, so if there is a Zookeeper or Cat Lady on the field and you saved 5 brains, you can destroy a plant while boosting your pets. However, this part should only be taken as extra gravy, as swarming cheaper pets is a more viable strategy for a pet deck.
Most Beastly heroes would bring Locust Swarm to destroy any strong plant, so pay attention to the brain counter. If you see your opponent has saved at least 5 brains, then there is a high chance that Locust Swarm will be played. The best counter to this trick is Umbrella Leaf, as she makes all plants invulnerable to it, although Umbrella Leaf herself isn't. If you don't have her, conserving your stronger cards is a good (but slightly risky) strategy too.
You should also be wary if your opponent has a Zookeeper or Cat Lady on the field, because Locust Swarm can activate their abilities.
