The Silent Invasion: Facing Cockroaches in Your Home


Cockroaches, those unwanted and often invisible guests, can be a real headache for homeowners. Despite their tendency to stay hidden, their presence is no less a major problem. If you’re wondering how these little intruders get into our homes, the answer is often simpler than one might think. Attracted by warmth and food, they find in our homes the perfect refuge.

Contrary to what one might think, detecting a cockroach infestation is not always obvious. However, there are telltale signs: tiny droppings, eggs, or even a peculiar odor. Knowing where to look is essential. These creatures often hide in dark and damp places, like under sinks or behind household appliances.

But then, how to get rid of these pests once their presence is confirmed? It’s crucial to understand that home solutions are often not enough and that calling in professionals might be the best decision. In the meantime, maintaining strict hygiene and limiting sources of water and food can help make your home less attractive to these little invaders.


Cockroaches are attracted to our homes by several factors, often related to our daily habits. Here are some of the most common elements that attract them:

  • Food Sources:
    • Crumbs on the floor or work surfaces.
    • Uncovered or inadequately stored food.
    • Dirty dishes and food residues in the sink.
    • Compost and decomposing organic matter.
    • Pet food left out in the open can attract them.
    • Uncovered or poorly managed trash cans.
  • Water and Moisture:
    • Water leaks, even minor ones, under sinks or around pipes.
    • Wet areas like bathrooms or basements.
    • Indoor plant saucers where water can stagnate.
  • Shelter and Warmth:
    • Warm and dark areas like behind refrigerators or ovens.
    • Cracks in walls, baseboards, or around windows.
    • Clutter and disorder, offering ideal hiding spots.

By understanding what attracts cockroaches, you can take preventive measures to reduce the risk of infestation. Keeping the house clean, properly storing food, and repairing water leaks are key steps to keep them at bay.

Detecting a cockroach infestation can be challenging, as these insects are often nocturnal and hide during the day. Here are some signs indicating their presence:

  • Living or dead cockroaches, often seen at night.
  • Exuviae (skins left behind after molting) in hidden areas.
  • Oothecae (egg sacs) in corners or cracks.
  • Small black or brown droppings, resembling grains of pepper.
  • Dark spots or traces of droppings on surfaces or walls.
  • Observation of greasy marks or regularly traveled trails by these insects.
  • Sudden or exacerbated allergic reactions, due to allergens left by cockroaches.

The presence of these signs strongly suggests a cockroach infestation. In this case, it’s advisable to act quickly to control and eliminate the problem before it worsens.

Cockroaches prefer dark, damp, and warm places to hide. Here are some of their most common hiding spots:

  • Under and behind the refrigerator.
  • Beneath and around the kitchen sink and bathroom basin.
  • Inside electrical appliances, like ovens, dishwashers, and microwaves.
  • In food storage areas.
  • In kitchen cabinets.
  • Behind the bathroom mirror.

Practical Tip: A simple way to check for cockroaches is to move the refrigerator or dishwasher. These areas are often overlooked during cleaning and can harbor cockroach activity. If you observe signs of their presence, such as droppings or the cockroaches themselves, it’s time to consider control measures.

By identifying and regularly inspecting these potential hiding spots, you can detect a cockroach infestation earlier and take necessary steps to eliminate them.


Eliminating cockroaches can be challenging, but with the right methods, it’s possible to control and reduce their population. Here are some effective strategies:

Traps, Baits, and Non-Repellent Insecticides

  • Use sticky traps or specific chemical baits for cockroaches.
  • Place them strategically in areas where cockroach activity has been observed.

Avoid Repellents

  • Avoid using repellents that can disperse cockroaches to other areas of the house.

Thorough Cleaning

  • Ensure your kitchen and bathroom are clean and free from crumbs or food residues.
  • Regularly empty trash cans and keep them closed.

Elimination of Water Sources

  • Repair water leaks and dry out damp areas.
  • Avoid leaving stagnant water in plant saucers or dish pans.

Securing Food

  • Store food in airtight containers.
  • Do not leave pet food out in the open.

While these measures can help reduce the presence of cockroaches, a significant infestation may require a more professional approach.
