In plain English, they made mosquitos like repellent.

Could this already be happening out in the wild?

I hope these mosquitoes were not released in the wild.

The simple answer would be to add a natural strongly repellent gentle oil to the DEET spray.

that explains. I was always wondering why in Siberia (where i worked for 2 summers back then at university times) coming out from house with freshly applied DEET you're getting covered with mosquitos - i was attributing that to the especial ferociousness of the mosquitos there - yet it sounds like the smell of DEET for them in those towns may have become like a BBQ smell for us :)
