The EMP Communication Device, also called the Ant Training Device, is a contraption created by Hank Pym to communicate with Ants. It uses electromagnetic waves to stimulate the olfactory nerve center of insects and mimic their pheromones, allowing the user to communicate with and control them. It takes mental and emotional commitment to get the insects to respond to the device's effect. The device is now a part of the Ant-Man Suit and also comes in the form of earpieces give to his daughter and Scott Lang.
