What Attracts Cockroaches in your house? 

Cockroaches are one of the most common and annoying pests that can infest your home. They are attracted by various factors, but mainly by food, water, and shelter.

Here are some of the things that can attract cockroaches to your home:

  • Food: Cockroaches are not picky eaters. They will feed on almost anything that contains organic matter, such as crumbs, spills, leftovers, pet food, garbage, paper, glue, and even feces. They are especially drawn to strong smells and sugary or starchy foods.
  • Water: Cockroaches drink water to stay hydrated and to dissolve their food. They can go for weeks without food, but only a few days without water. Therefore, they are attracted to moist and humid environments, such as pipes, drains, faucets, sinks, bathtubs, toilets, and puddles. They can also get water from condensation, leaks, or damp materials. Additionally, cockroaches are attracted to toothbrushes. The problem of Cockroaches on Toothbrushes is an issue that needs to be addressed promptly.
  • Shelter: Cockroaches like to hide in dark and cozy places where they feel safe from predators and disturbances. They are attracted to cracks, crevices, gaps, holes, and other openings in walls, floors, ceilings, cabinets, furniture, appliances, and electrical outlets. They can also hide under carpets, rugs, cardboard boxes, paper bags, books, magazines, and clothes.
