What Are Cockroaches?

Learn About Cockroach Infestations and How to Get Rid of Them Fast

Cockroaches are one of the most common—and unwanted—household pests. These insects have been around for over four million years and thrive in warm, moist environments. With more than 3,500 species worldwide, they are known for their ability to spread disease and contaminate food.

🐜 Most Common Type: The German Cockroach

The German cockroach is the most common species found in homes and buildings across the globe. These small, tan-colored insects (1.3 to 1.6 cm in length) have two dark stripes running down their backs. They prefer warm, humid environments and are often found in:

• Kitchens
  
  

• Bathrooms
  
  

• Restaurants
  
  

• Hotels
  
  

• Nursing homes
  
  

Note: German cockroaches have wings but cannot fly.

⚠️ Are Cockroaches Dangerous?

Yes, cockroaches can be a serious health hazard:

• They contaminate food and surfaces by walking through garbage, drains, and sewers.
  
  

• Their droppings, saliva, and shed skin can trigger allergies and asthma—especially in children.
  
  

• They spread bacteria such as E. coli and Salmonella.
  
  

Their presence does not always mean your home is dirty—they are attracted to any space with food, water, and shelter.

🚪 How Do Cockroaches Get Into Your Home?

Cockroaches can hitchhike into your home through:

• Used furniture
  
  

• Grocery bags and food containers
  
  

• Cardboard boxes and drink bottles
  
  

• Plumbing and utility openings
  
  

Once inside, they multiply quickly and are most active at night, making early detection difficult.

DIY Jar Trap Instructions:
