In 2014, a patent was filed with the United States Patent and Trademark Office (USPTO) that outlines the future – which is now the present – of chemical and biological warfare.
Entitled “Toxic mosquito aerial release system,” the patent, which was issued as US8967029B1, outlines a system of spraying for biological, chemical, or other materials using “unmanned aerial vehicle[s] operable by remote control.”
“It carries a container holding a central processing unit and a mosquito breeding bin, which is a self-contained volume housing mosquitoes and a mosquito food having a toxin suitable to be transmitted by mosquito bite after the mosquito consumes the mosquito food,” the abstract further states.
