Key Takeaways

  • Using weak household pesticides makes cockroaches gain immunity, requiring stronger doses.
  • Neglecting to seal cracks provides safe havens that pesticides can't reach.
  • Leaving food crumbs and dirty dishes at night is an open invitation for roaches.
  • Unfixed water leaks (under the sink) provide the humidity needed for roach eggs to survive.
  • Spot spraying isn't enough; nests must be targeted using long-lasting gel technology.

Cockroaches are the world's most adaptable creatures. Many families in Saudi Arabia suffer from a repeated "spray and reappear" cycle. The truth is that pesticide alone is not a magic solution without sealing the gaps that allow them back.
