Cockroach Infestation- What to Look For?

Since roaches are nocturnal insects, they often look for dark and moist locations to hide and breed. So, ideally, they will find a shelter that provides them with a constant source of food. Here are the places where you can find them lurking around.

  • Kitchen: If there are any leaks or broken storage areas, you can easily find roaches inhabiting such areas. Not only that, sometimes they hide under bigger appliances, such as stoves and refrigerators.
  • Bathrooms: This is like their favorite home. Since the area is moist compared to other areas of your home, you can find them moving around in the pipes, bathtubs, showers, or drains.
  • Basement: They can squeeze within cracks, holes, or leaky pipes.
  • Laundry Room: You will find cockroaches hiding under the washers or a pile of clothes.

Now that you are familiar with their hideout places, the next step is to figure out the signs to identify them quickly. But before that, let’s take a moment to understand the types of roaches found in our homes.

To those who have no idea about cockroaches, let’s get one thing clear. They are omnivores and not at all fussy about their food. So, whether it’s a delicious pie or garbage, it’s a tasty treat for them.

As a result, they can retain disease-laden pathogens in their digestive systems. And when they poop, it can leave the pest body. And since pests don’t follow any bathroom hygiene, these droppings can pollute the food containers or kitchen surfaces. And eventually, result in spreading microbes to people.

In fact, as per the WHO, there are more than 60 different types of pathogens that can reside in these creepy crawlers like Salmonella, E.coli, Giardia, Staphylococcus aureus, and so on. Thus, it goes without saying that it could impact the health of the family in many ways.

For instance, as per a study, more than 63% of homes with cockroaches resulted in the rise of people with asthma. As per professionals, you can catch a disease in many ways. However, the most common reason is eating the food items that are contaminated with these creepy crawlers’ poop or saliva.
