Cockroaches are one of the world’s most tenacious creatures. After decades of dwindling numbers due to the advancement in professional pest control products, they have rebounded with a vengeance! These persistent critters are becoming resistant to commonly-used pesticides and are now building up their populations once again. They continue to persevere due to a number of survival strategies that have evolved over the span of 300 million years.

There are many species of cockroaches, the most common are the German Cockroach.

Characteristics of German Cockroaches

The German cockroach is brown with two black horizontal stripes on their pronotum (the shield-like structure partially covering the insects head and thorax) from behind their head to the base of wings. They are 11 mm to 16 mm in size (adults are 1/2 to 5/8 inches long). Adults are winged although they cannot fly. After mating, females can produce an egg sac every six weeks containing 30 – 48 eggs.

Cockroaches prefer warm, moist environments and like to hide in kitchens, washrooms, and laundry rooms although they can also be detected in all areas of a residence.

German cockroaches carry disease-causing organisms on their legs and bodies and can deposit them in your food, on your dishes and utensils. Their cast skins (cockroaches shed their skin as they grow) and excrement can cause allergic reactions and aggravate symptoms of asthma.

Signs of Cockroaches

  • Cockroach droppings are dark brown or black and cylindrical-shaped (I – 2 mm long).
  • Cockroaches shed their skin several times as they mature. The shed skins are usually found close to their hiding-places.
