The document discusses developing prototypes to trap cockroaches. Five prototypes were designed and tested: 1) A box with carpet, vaseline, and food to attract roaches inside. 2) A trap with honey coating the inside from top to bottom. 3) A trap using peanut butter. 4) Jam jars with vaseline around the top and food inside. 5) Plastic bottles with sugar water, tissue, and a dark cylinder to attract roaches inside. Prototypes 1-3 were tested for 3 days with limited success, while prototypes 4 and 5 were tested for a week in a shed, with prototype 4 catching 6 roaches and prototype 5 catching none.
