Why Cockroaches Are in Your Home or Yard

Attracted to Food and Water Sources

• Crumbs, spills, and improperly stored food attract cockroaches.
• Leaking pipes, standing water, and moisture-rich areas provide hydration.

Seeking Shelter

• Cockroaches look for warm, dark, and secluded places to hide and breed.
• Yards with overgrown vegetation, woodpiles, or debris provide excellent outdoor hiding spots.

Seasonal Movement

• In summer, roaches may move indoors to escape extreme heat.
• During cooler months, they seek warmth inside homes.
