Good business opportunity here. Selling lasers and particularly masers that can shoot the drones down. MASER - Microwave Amplification by Stimulated Emission of Radiation. Where can you find a simple maser? In your microwave oven. Simply take the working microwave 'gun' out of a microwave oven, wrap some aluminum flashing around it to protect yourself from microwaves - leave a hole in the front for the MWs to get out, add a source of power, and turn it on, directing it at the drones. BE CAREFUL, YOU CAN BURN OR BLIND PEOPLE, OR WORSE, IF YOU AIM IT AT THEM. You might want to make it portable by adding a battery pack and transformer unit. USE AT YOUR OWN RISK.
