Cockroaches are irritating insects that can nest anywhere in a home and become a real problem. They are among the species that most annoy people, and the issue is that they can be present without notice. The truth is that when they are seen during the day, it often means the infestation has already reached a large level because cockroaches are nocturnal and tend to stay hidden during daylight hours.

Where do cockroaches hide?

To be precise, cockroaches don’t simply hide; they establish nests. As noted earlier, they are nocturnal creatures. Here are four characteristics of ideal nesting habitats for cockroaches:

  • Heat
  • Moisture
  • Darkness
  • Food, especially organic residues and oils

Cockroaches can shelter in damp and shadowy corners.

Therefore, any space that gathers them can host a nest:

  • In cracks and behind baseboards
  • Drains and pipes
  • Behind kitchen cabinets
  • In exhaust hoods
  • Near motors of household appliances
