Cockroaches can measure over 50 mm (2 in) length, with tropical species tending to be larger than those found in other climates. Cockroaches have six legs, two antennae, and some even have wings. However, most winged cockroaches are not particularly adept at flying. With flat, oval-shaped bodies, these pests are often oily to the touch and may feel cool or warm, depending on the temperature of their environment.Cockroaches in the house are better at hiding than you are at finding them, and their eggs are naturally protected from many over-the-counter insecticides and are elusive when it comes to cockroach traps. Without special equipment, materials, and know-how, pest control for cockroaches can be a losing battle.
