How to Spot, Prevent & Eliminate Cockroach Infestations
Cockroaches are some of the most persistent (and unanimously despised) pests on the planet. These nocturnal insects can squeeze into tiny cracks, survive for weeks without food, and even develop resistance to certain pesticides.
But beyond their ability to totally gross you out, cockroaches can pose serious health risks by spreading bacteria, triggering allergies and contaminating food.
If you’ve spotted one in your home, building or business, there’s a good chance more are hiding nearby. Here’s what you need to know about cockroach infestations and how to stop them before they take over.
Signs of a Cockroach Infestation
Cockroaches are experts at staying out of sight, but they leave behind plenty of evidence. Some of the most common signs include:
- Droppings: small, dark, and similar in appearance to coffee grounds or black pepper
- Egg Casings: brown, oval-shaped sacs (called oothecae) that contain multiple eggs
- Musty Odor: a strong, unpleasant smell that worsens as the infestation grows
- Shed Skins: cockroaches molt multiple times before reaching adulthood, leaving behind their exoskeletons
- Smear Marks: dark streaks on walls or floors where roaches travel frequently
- Live Sightings: spotting roaches during the day often indicates a severe infestation
Why Cockroaches Are So Hard to Get Rid Of
Cockroaches multiply quickly, making infestations difficult to control. Some species can lay dozens of eggs at a time, and their ability to hide in hard-to-reach areas allows them to avoid DIY treatments. They’re also highly adaptable — some can survive without food for a month and without water for a week.
Additionally, roaches can develop resistance to over-the-counter insecticides, making store-bought sprays and baits ineffective over time.
How to Prevent Cockroach Infestations
- ✔ Eliminate Food Sources: keep food in sealed containers, clean up crumbs and spills immediately, and don’t leave dirty dishes in the sink
- ✔ Reduce Moisture: fix leaky pipes, use dehumidifiers, and empty pet water bowls overnight
- ✔ Seal Entry Points: fill in cracks around windows, doors, and plumbing with caulk or weather stripping
- ✔ Declutter: roaches love hiding in cardboard boxes, stacks of paper, and dark corners—keep storage areas tidy
- ✔ Take Out the Trash: use a trash can with a tight-fitting lid and empty it regularly
