Can roaches climb glass or plastic?
Some species of roaches can climb right up glass or plastic and others can not. Orange Headed Roaches, Discoid Roaches, Orange Spotted Roches and Turkistan Roaches are non-climbers. Hissing Roaches and Lobster Roaches will climb but can easily be contained by smearing a two inch strip along the top of the tank with Vaseline or olive oil.
