Pest Control for Cockroaches

Just the sight of a cockroach crawling across the floor is enough to make anyone uncomfortable. But what exactly are you dealing with?

Cockroaches are large, hardy insects with six legs and 18 joints. There are more than 5,000 species worldwide, but the most common include the German cockroach and the American cockroach.

How Cockroaches Enter the Home

Cockroaches often enter homes from outside by finding small cracks, gaps under doors, and other entry points. They are attracted to warmth, darkness, and accessible food or water sources, such as:

  • Open garbage bins

  • Unwashed dishes

  • Spilled or exposed food

Despite their size, cockroaches can squeeze through openings as small as a dime when young and a quarter when fully grown. Because they avoid light, infestations often go unnoticed until they become more severe.

Signs of Infestation

One common indicator of a cockroach problem is the presence of droppings, which appear as small, black, gritty specks with an oily texture. These are often found in:

  • Cupboards

  • Under appliances

  • Basement corners

  • Other dark, hidden areas

Getting Rid of Cockroaches

Good hygiene is the first step in controlling cockroaches. This includes:

  • Removing rotting food and food waste

  • Storing food in sealed containers

  • Using tightly sealed garbage bins

  • Cleaning under appliances and in hidden areas

Once cleanliness is addressed, treatment options include DIY methods or professional pest control services, depending on the severity of the infestation.

Common control methods include:

  • Contact insecticides (direct kill sprays)

  • Residual sprays (long-lasting treatments that continue working for 2–3 weeks)

  • Bait stations such as “roach motels” placed in infested areas

In some cases, a combination of treatments is necessary for full control. After elimination, preventative measures such as boric acid powder can be used in wall voids and around foundations to help deter reinfestation.

Safety Considerations

Pesticides can be harmful to humans and pets if not used correctly. Always:

  • Remove food, dishes, and pets before treatment

  • Follow product instructions carefully

  • Use proper ventilation and protective equipment when required
