Iirc there is a massive breeding factory in Central America that breeds sterile flies to help decrease the fly population. It works great, they produce tens of millions of these sterile, sexy (to other flies) bugs every year. The other flies fuck them and they never produce offspring.
So the Trump admin stopped funding them because "hurr durr why are we funding a fly bordello in panama". Now they're producing like 10% of what they were before
So: voíla, flesh eating flies and now we have to start funding the lab again AND stop an invasive species that's here now.
