If you are not aware, screw worm is rapidly gaining ground towards the United States' southern border.
No animals are being allowed to cross over the border at this time. If you have questions or concerns, please feel free to ask me or another animal health professional about it.
In brief, these are flesh eating flies that get into wounds and newborn animal's navels causing stress/illness and even death. Imagine a fly season where you had to worry about every scrape or baby getting infested with flesh eating maggots.
Thankfully, there is a weakness to them. The females only mate once during their life, so if the male fly they mate with is sterile, none of their eggs hatch. There are sterile male flies ready to go and already being used in Mexico.
