Cockroaches are hardy, flat-bodied insects that most people recognize instantly. They have been around for hundreds of millions of years, and part of what makes them so well-known is just how good they are at surviving. With their long antennae, quick movements, and tough exoskeletons, cockroaches can slip into tiny spaces and scavenge just about anything. They are not picky eaters at all rotting food, paper, fruits, almost nothing is off-limits. That\u2019s one reason they do so well in human homes, especially in warm, dark, and damp places like kitchens and basements.<\/p>\n

Despite their reputation, cockroaches don\u2019t bite, and they are not aggressive. Still, they can be a problem indoors because they are known to carry bacteria and allergens, especially when infestations get out of hand. But outside of human spaces, many species of cockroaches live relatively unnoticed, doing important ecological work. In forests, for example, they help break down decaying plant material, speeding up the process of nutrient recycling.<\/p>\n

      \u00a0Diet & feeding habits<\/h4>\n

      Cockroaches are omnivorous scavengers. They eat:<\/p>\n

        \n
      • \n

        Decaying plant matter<\/p>\n<\/li>\n

      • \n

        Starches, sweets, meat scraps<\/p>\n<\/li>\n

      • \n

        Paper and cardboard in extreme cases<\/p>\n<\/li>\n<\/ul>\n

        They use chewing mouthparts to grind food and can survive on very little, sometimes just glue or soap.<\/p>\n

          Egg<\/strong> \u2013 Produced in a protective case (ootheca)<\/p>\n<\/li>\n

          Adult<\/strong> \u2013 Fully developed wings in many species<\/p>\n<\/li>\n<\/ol>\n

          Females can produce multiple oothecae containing 10\u201350 eggs each.
          Some species can reproduce without males (parthenogenesis).<\/p>\n
