Owing to the open-ended wording of your wish, since there are no ants inside your body, all ants in a 50-radius have instantaneously taken residence within every available cavity of your body. You find yourself amazed by just how many ants that actually is in the few seconds you have before your body bursts and you die in horrific but brief agony.

Granted but every time you do, you draw every other insect in the radius to your location

Granted. The conservation of entropy theorem that is the backbone of teportation means that upon teleport, the difference in entropy between origin and destination measured in mass-energy-entropy would have to be “antimatter ants” for each equivalent unit of mass-energy-entropy as you specified only a destination, that means that you probably only 10x’d the net quantity of ants whenever this teleportation is used.
