How to Tell If You Have a Cockroach Infestation
Do you think you have a roach infestation but haven't seen any actual roaches? Because cockroaches are primarily nocturnal insects, it is more likely you will see signs of a cockroach problem before you see a roach itself.
Roaches only leave their hiding spots to search for food. This usually happens late at night when they have a lesser chance of being caught. Cockroaches love all sorts of food including garbage, pantry snacks, and even somethings we would not think of like paper and packaging.
If you believe you have a roach problem in your home it is best to call a pest professional as soon as possible.
Signs of Cockroaches
Since we know that cockroaches are primarily nocturnal we know that we will not see roaches themselves very often. Even if we do not see them, they can still be spreading dirt and bacteria all over your home. Here are a few easy signs to look out for when trying to identify a cockroach infestation.
Like every other animal, roaches poop too. Cockroach droppings look similar to coffee grounds, black pepper or spotted mold. Inspect areas under and around your garbage, refrigerator and sink. If you find or suspect cockroach droppings it is important to wear a glove and mask when inspecting and cleaning. Because roaches anything and everything, their droppings are filled with lots of bacteria and harmful pathogens.
Some cockroaches lay up to 40 eggs at one time in what is known as an egg capsule. Capsules look different for different types of cockroaches. In general, they tend to be long rounded tan or brown capsules. Some capsules like the German Cockroaches' egg sack has many ridges and others are quite smooth. This photo by the University of Nebraska Department of Entomology shows a few of the different types of egg capsules.
Smear marks are caused by a roaches body rubbing or smudging areas in high moisture. You may see these marks on walls or floor boards where roaches crawl or rest.
Like many other insects, when cockroaches grow, they shed their skin. A cockroach may shed its skin 5-8 times on its way to adulthood. These left pieces of exoskeleton vary in size and shape. Some pieces may look like a little white roach ghost while other pieces may tan segments or legs.
As we know, roaches will eat just about anything and everything. Because of this, you may notice nibbles on chip bags, leather goods, and even book pages. This can be tough to identify if you do not know what you are looking for.
Roaches leave unpleasant scents behind for a variety of reasons. Many cockroaches spend their time exploring garbage and sewage. Roaches can help spread those already gross smells around your home. As well, the roaches themselves release pheromones that create a musty sort of scent. The larger the cockroach infestation the stronger the smell will be.
Because roaches are nocturnal, it is unlikely you will see them during the day; however, a quick midnight trip to the fridge or bathroom may reveal many unwanted guests. Different roaches like to spend their time in different areas. For example, the German Cockroach prefers to live in warm humid places such as a bathroom. In comparison, the American Cockroach spends more time outside in areas like the garage and basement.
