👉 A cockroach, also known as a cockerel, is an insect that is commonly found in gardens and is often referred to as a "cockcrow" due to its appearance. It can be very small and can grow up to 1 inch long, with wings that are slightly longer than the body. Cockroaches are typically harmless insects but if they become infested with fleas or other pests, they can cause damage to plants and homes.
