Ants probably can’t create so much electricity. But every higher living being can create a little voltage inside them, thanks to neurons(About 0,03 V). But since they have triple helix, the third strand can enhance existing genes, so they could create much more electricity. And when there is a lot of them, it could create pretty big blast. On the other hand, electric eels have cells called electrocytes, which can create electricity same way neurons do. But hey, that’s just a theory! :D
