The Biden administration’s open border policies created more than just a security crisis.
They may have opened a pathway for deadly parasites to invade America.
And a nightmare scenario got more terrifying as this deadly threat moves toward the border.
Border crisis creates perfect storm for biological invasion
For four years, the Biden-Harris administration allowed millions of illegal aliens to pour across the southern border through well-established caravan routes.
Those same pathways that brought drugs, criminals, and unvetted migrants into American communities are now being used by something far more sinister.
Flesh-eating flies known as New World Screwworms are moving north through Mexico using the exact same routes that over 1.2 million migrants used to reach the United States between 2021 and 2024.
The timing is no coincidence.
These parasitic insects lay hundreds of larvae in open wounds of animals and humans, which hatch within hours and begin consuming the victim’s flesh from the inside out.
Officials in Mexico have discovered several cases in the southern states of Chiapas, Oaxaca, and Veracruz – all key stops along the migrant caravan route that the Biden administration refused to secure.
Mexico reported its first human case in April 2025 – a 77-year-old woman from Acacoyagua, Chiapas, who was stabilized and treated with antibiotics.
A second case involved a 50-year-old man from the same region who was bitten by a dog, creating an open wound that became infested with the parasitic larvae.
America’s food supply under threat
The economic devastation these insects could cause is staggering.
Texas alone is home to 14 percent of all cattle in the United States.
If these flesh-eating flies establish themselves in America, beef and dairy prices would skyrocket as livestock die from the infestations.
Food shortages would follow, hitting working families already struggling with inflation the hardest.
"It can have a huge impact, certainly an economic impact, because it decreases the health and wellness of our livestock," Texas Tech School of Veterinary Medicine Associate Professor Jennifer Koziol told Drovers.
The professor warned about the broader implications: "We’re thinking about loss of animal use, and certainly thinking about our wildlife populations that could be decimated by this disease."
In the early 1900s, screwworms cost America $200 million – equivalent to $1.8 billion today – in infected livestock before the United States successfully eradicated them in 1982.
Now they’re back, and they’re following the same routes that brought millions of illegal aliens into our country.
Climate change excuse masks border failures
Predictably, so-called experts are blaming climate change for the spread of these deadly parasites.
According to a 2019 study, at least five states – Texas, Florida, Louisiana, Arizona, and California – could be infested with screwworms by 2055 due to "rising temperatures."
But the real culprit isn’t the weather.
These insects broke through containment barriers at Panama’s Darién Gap in 2022 – the same treacherous passage that over 1.2 million migrants crossed to reach America during the Biden administration’s border catastrophe.
The Darién Gap became notorious for its high injury rates among the massive caravans attempting to reach the United States through Mexico.
Those open wounds created the perfect breeding ground for New World Screwworm infestations.
The insects then followed the migrant trail north, just like the drugs, criminals, and gang members who used the same pathways.
Trump administration takes action
President Donald Trump’s administration is already working to address this crisis that was inherited from the previous administration.
In May, the United States officially suspended imports of live cattle, horses, and bison from Mexico after screwworm cases were found within 700 miles of the southern border.
Agriculture Secretary Brooke Rollins announced a $21 million partnership with the Mexican government to eradicate the insects before they can spread further north.
The money will fund efforts to renovate an existing fruit fly production facility in Metapa, Mexico, which will produce 60 to 100 million sterile male flies every week.
"The investment is one of many efforts my team is making around the clock to protect our animals, our farm economy, and the security of our nation’s food supply," Secretary Rollins said in a statement.
Additionally, the Trump administration announced an $8.5 million sterile fly dispersal facility at Moore Air Base in Texas, which will be operational by the end of 2025.
"Producing sufficient numbers of sterile flies and getting them released in the correct places and at the right time is critical," said Phillip Kaufman, a professor of entomology at Texas A&M University.
"If the flies move further north than the isthmus in southern Mexico, it becomes more and more challenging to contain them," he told Newsweek.
The flesh-eating flies are now just 700 miles from the American border and moving north along the same routes that brought chaos to our communities for four years.
This is what happens when a government abandons its most basic responsibility to secure the nation’s borders.
The Biden administration’s reckless open border policies didn’t just create a humanitarian crisis – they may have opened the door to a biological invasion that could devastate America’s food supply and threaten the lives of American citizens.
President Trump inherited this mess, but he’s already taking decisive action to protect the homeland that his predecessor left vulnerable to attack.
