ELI5: How can an Aardvark consume so many ants at once and endure the pain of the ants biting its tongue?

Sort of a left field question, but I was thinking that there would be considerable pain inflicted when consuming a mound of fire ants.

Not an aardvark, but anteaters have certain defenses:

"To avoid the jaws, sting, and other defences of the invertebrates, anteaters have adopted the feeding strategy of licking up large numbers of ants and termites as quickly as possible — an anteater normally spends about a minute at a nest before moving on to another — and a giant anteater has to visit up to 200 nests to consume the thousands of insects it needs to satisfy its caloric requirements." (from Wikipedia).

Also, aardvarks are native to Africa, but fire ants are native to South America.
