Quick answer

What to know first

Cockroach prevention focuses on the rooms where food, warmth, and moisture overlap. Kitchens, bathrooms, laundry rooms, and utility areas should be kept dry, sealed, and easy to inspect.

Check first

  • Droppings in cabinets, drawers, or behind appliances
  • Musty odor in enclosed storage areas
  • Nighttime sightings near sinks or food storage

Avoid this

  • Treating only insects that are visible during the day
  • Spraying over bait placements or leaving competing food available
  • Ignoring leaks, appliance voids, and neighboring-unit activity

FAQ

Do cockroaches mean a home is dirty?

Not always. Roaches can enter through shared walls, boxes, drains, and deliveries, but sanitation reduces survival and breeding.

Where should monitors go?

Place them where walls meet appliances, pipes, cabinets, and other protected edges.
