I'm a bit disappointed that there's no mention of mini laser cannons strapped to these drones. That would be way cooler, especially at night, and much more environmentally friendly compared to pesticides.
Seems like the laser technology is patented and they are aiming for fixed defenses though, so it won't be in drones anytime soon. Also lasers have more safety concerns than insecticide.
Maybe a spike on one side of the drone, and it flies into the target. Or a spike shoots out one side, along with a counterweight motion, and then retracts.
Edit: on second thought, it’s likely less practical to impale the things than to inject a small dose of poison or electrocute them or something, and it’s probably easier to use a ground-based robot for such precision tasks, with less energy and mass constraints.
