On May 1, 2039, I caught a picture of this machine. Called the Sprayer-Slayer, it's an exterminator for your backyard. Pest DNA is inserted to a neutral liquid held in its tank. The spray will only harm the creature of that DNA. It constantly roams and scans the yard, finding pests that need to be exterminated. It saves money on exterminators, using a fail-proof method to verify that only targeted pests are affected. Above, it's inserting the blue ant DNA while eliminating an ant colony.
