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.

"A release tube is connected to the mosquito breeding bin and sized to release mosquitoes from the mosquito breeding bin. A valve is connected to the release tube and is operable by remote control so that when opened, the mosquitoes have an open pathway out of the container through the release tube."
