Pro 8 Investigates: Are river wasps dangerous?
As our Sister City prepares to release tens of thousands of wasps in an effort to help control the rapid growth of the carrizo cane, some residents on this side of the border question if the insects could threaten our health or even safety.
When you think of wasps, you picture larger ones, which often are more dangerous than bees. But the tens of thousands of wasps to be released along the Rio Grande in Nuevo Laredo do not have any stingers.
Environmental scientist, Tom Miller says the wasp is a "Tetramesa Romana."
He took us through a trail along the Rio Grande in search of that insect.
We found one sticky trap and it's so small that most people wouldn't even see it.
Miller says the first purpose of getting rid of this invasive plant is because it consumes large amounts of water. With 30 to 40-thousand acres of cane scattered from Laredo to Del Rio, that's equal to billions of gallons of water every year.
