What Causes Cockroaches in Your House & How to Get Rid of Them

Few household pests are as unsettling as finding a cockroach scurrying across your kitchen floor or disappearing under your appliances. Whether you spot one in the middle of the night or discover signs of a larger cockroach infestation, it’s important to act quickly. Cockroaches contaminate food, spread bacteria, trigger allergies, and multiply rapidly if left untreated.

Cockroaches are one of the most common pests found in Maryland homes, including Baltimore and the surrounding communities. While DIY methods may help reduce small infestations, severe problems often require professional cockroach extermination from an experienced Maryland pest control company.

Below, we’ll explain how to identify the most common species of cockroaches, what attracts them to your home, and the best ways to eliminate them.

Identifying Cockroaches in Maryland

Correctly identifying the species you’re dealing with can help determine the most effective cockroach treatment.

American Cockroach

The American cockroach is one of the largest species found in Maryland, measuring up to two inches long. Despite its name, it actually originated in Africa. These reddish-brown roaches are commonly found in basements, crawl spaces, utility rooms, and sewer systems before making their way indoors.

German Cockroach

The German cockroach is the most common indoor species and the one most likely to cause a serious cockroach infestation. Measuring only about half an inch long, these light brown roaches reproduce extremely quickly and often hide behind appliances, inside cabinets, and near food sources.

Because they breed so rapidly, German cockroaches often require professional cockroach extermination rather than DIY treatments.

Oriental Cockroach

The Oriental cockroach is dark brown to shiny black and about one inch long. These roaches prefer cool, damp environments such as basements, crawl spaces, drains, and around leaking pipes.

Signs of a Cockroach Infestation

Many homeowners don’t actually see cockroaches until the infestation has grown. Watch for these common signs of a cockroach infestation:

  • Cockroaches seen during the daytime

  • Small black droppings that resemble coffee grounds

  • Egg cases (oothecae)

  • Musty or oily odors

  • Smear marks along walls

  • Shed skins

  • Damage to food packaging

If you notice several of these warning signs, it’s time to contact a roach exterminator in Maryland before the infestation becomes more difficult to eliminate.

What Attracts Cockroaches?

Understanding what attracts cockroaches can help prevent future infestations. Cockroaches are constantly searching for three things:

  • Food

  • Water

  • Shelter

Common attractants include:

  • Dirty dishes left overnight

  • Food crumbs

  • Grease buildup

  • Pet food left out

  • Leaking pipes

  • Standing water

  • Overflowing trash cans

  • Cardboard boxes

  • Cluttered storage areas

Removing these food and moisture sources is an important part of long-term cockroach prevention.

How to Get Rid of Cockroaches

If you’re wondering how to get rid of cockroaches or how to get rid of roaches, there are several treatment options available.

Cockroach Traps

Glue traps and baited traps are inexpensive and readily available. They attract cockroaches with food or pheromones before trapping them inside. While traps help monitor activity and reduce small populations, they rarely eliminate an entire infestation because they do not reach hidden nests.

Cockroach Baits

One of the most effective DIY methods is using insecticide bait stations. Worker cockroaches consume the bait and carry it back to the nest, where it is shared with other cockroaches. This allows the treatment to spread throughout the colony and kill multiple generations. Proper placement is critical. Position bait stations:

  • Behind refrigerators

  • Under sinks

  • Behind stoves

  • Near dishwashers

  • Inside cabinets

  • Along baseboards

Seal Entry Points

Even after eliminating existing cockroaches, new ones can enter your home through surprisingly small openings.

Inspect your home for:

  • Cracks in foundations

  • Gaps around plumbing

  • Utility penetrations

  • Damaged weatherstripping

  • Openings around doors and windows

Sealing these entry points is one of the best ways to improve long-term roach prevention.

Keep Your Home Clean

Good sanitation is one of the simplest ways to discourage cockroaches.

Make it a habit to:

  • Wipe down kitchen counters daily

  • Sweep crumbs regularly

  • Store food in sealed containers

  • Take out trash frequently

  • Fix plumbing leaks promptly

  • Vacuum under appliances

  • Clean grease from stovetops and cabinets

A clean home won’t always prevent cockroaches, but it makes your property much less attractive to them.

Boric Acid

Boric acid has been used for decades as an effective DIY cockroach treatment.

Mix equal parts:

The sugar attracts the cockroaches while the boric acid destroys their digestive system. Be sure to keep boric acid away from children and pets, and always follow product label instructions.

Baking Soda

Another popular home remedy combines chopped onion with baking soda. The onion attracts cockroaches, while the baking soda reacts with acids inside their digestive system. Although inexpensive, baking soda generally works best on small populations and should not be relied upon for a severe roach infestation.

Lemon Juice

Cockroaches dislike citrus scents. Adding lemon juice to mop water or mixing it with water in a spray bottle may help discourage cockroaches from entering certain areas of your home. While lemon juice is safe and natural, it should be viewed as a preventative measure rather than a complete solution for cockroach removal.

Are Cockroaches Dangerous?

Many homeowners ask, “Are cockroaches dangerous?”

Unfortunately, yes.

Cockroaches can carry bacteria and other pathogens on their bodies after traveling through garbage, sewers, and drains. They may contaminate food preparation surfaces and have been associated with bacteria such as Salmonella and E. coli. Their droppings, saliva, and shed skins can also trigger allergies and worsen asthma symptoms, especially in children.

Because of these health concerns, it’s important to address a cockroach infestation as soon as possible.

When Should You Call a Professional Cockroach Exterminator?

DIY treatments can sometimes reduce small infestations, but they rarely eliminate every hiding place or egg case.

If you continue seeing cockroaches after treatment, notice increasing activity, or find cockroaches in multiple rooms, it’s time to call a cockroach exterminator in Maryland.

A professional roach exterminator can:

  • Identify the species

  • Locate hidden nesting areas

  • Apply professional-grade products

  • Eliminate active infestations

  • Recommend long-term prevention strategies

  • Help prevent future infestations

Professional cockroach control in Maryland is often the fastest and most effective way to completely eliminate roaches from your home.
