Cockroach Control

Cockroaches thrive in areas that are warm and moist, and they’ll do whatever it takes to survive. Finding a cockroach doesn’t always mean your house is untidy. Even if you regularly clean, a cockroach can easily make its way into your home in search of food and water.

While you may be tempted to use store-bought pest products, you may only cause the cockroach infestation to spread. Fortunately, Antworks is here for you. We’ll perform a thorough inspection of your property to allow us to find typical signs of cockroaches and identify any potential shelter sites. We’ll then quickly treat your property and clean it afterward, leaving you with a safe and clean environment.

Common Cockroaches in the Portland and Vancouver Area

In the Pacific Northwest (PNW), we see several types of cockroaches, including:

American Cockroaches

What Is an American Cockroach?

A large reddish-brown American cockroach; common in Portland commercial buildings and sewer systems, requiring professional extermination.

American cockroaches are the largest cockroach species in the Pacific Northwest, with adults growing up to 1½”. Their color ranges from red to brown, and they have a distinctive light-brown band around the head. 

The American roach will regularly use its wings to fly. Adult American cockroaches may live up to around 15 months.

American cockroaches are found in large numbers in restaurants, multifamily housing, residential homes, and hospitals. American cockroaches are often found in restaurants and other commercial structures where food is prepared or stored, but they also attempt to gain access to multifamily or residential structures (often through sewer systems and piping).

How We Treat American Cockroaches

  • Inspection: A thorough inspection of conducive conditions, recommendations for prevention, and an assessment of infested areas are important for developing a treatment plan that works.
  • Treatment: There is a wide range of products available for roach control. Treatment may include a combination of gel baits, dusts, or liquid products to be applied. Your service technician will use the products they deem most appropriate and likely to produce the desired outcome.
  • Ongoing Prevention: In some cases, follow-up treatment may be necessary to control the roach infestation. Additionally, vigilance in keeping all areas as clean, sanitized, and clutter-free as possible will contribute to effective cockroach control.

Brown-Banded Cockroaches

What is a Brown-Banded Cockroach?

A brown-banded cockroach showing its light-colored bands; an indoor pest that infests dry areas of Vancouver homes like bedrooms and electronics.

Brown-banded cockroaches usually measure roughly ½” in size, and in color range from dark brown to dark red. 

Both male and female brown-banded roaches have wings, but only males can fly. 

Both genders have a light brown band running across the bases of the wings. Brown-banded cockroach nymphs will take three to six months to develop.

Unlike other cockroaches that prefer to infest kitchen and bathroom areas, brown-banded roaches will infest any room inside a house, making them harder to control.

How We Treat Brown-Banded Cockroaches

  • Inspection: Brown-banded cockroaches prefer warm, dry areas and are often found in upper cabinets, closets, electronics, and behind wall decor, so a focused inspection will target these elevated hiding spots and identify the extent of activity.
  • Treatment: Control usually involves strategic placement of gel baits, insect growth regulators, dusts, or residual products in cracks and high harborage areas where brown-banded roaches like to live and breed.
  • Ongoing Prevention: Since this species spreads quickly and easily throughout structures, follow-up visits are recommended. We also recommend reducing clutter, sealing entry points, and maintaining clean, dry conditions to prevent reinfestation.

German Cockroaches

What is a German Cockroach?

A light brown German cockroach with two dark stripes; the most common kitchen infesting roach for apartments and restaurants in the Portland metro area.

German cockroaches are the most common cockroach species in the Pacific Northwest. 

Brown in color, German cockroaches are typically up to about ½” long when fully developed.

One distinct characteristic is that adults will usually possess two dark brown stripes behind their heads. Adult German cockroaches have wings but rarely use them to fly. The German cockroach’s lifespan is typically around 1 year. German cockroaches reproduce more quickly than most cockroach species in the area, and they carry their eggs (40+) in an ootheca until they hatch. This makes them extremely prolific breeders and especially troublesome from a control standpoint.

How We Treat German Cockroaches

  • Inspection: German cockroaches thrive in warm, humid areas close to food and water, so inspection typically focuses on kitchens, bathrooms, appliances, plumbing voids, and tight cracks near sinks and stoves to determine the level and spread of activity.
  • Treatment: Effective control relies on carefully placed gel baits, growth regulators, and targeted residual applications in harborages such as cabinet hinges, drawer tracks, wall voidsnd behind appliances where German roaches hide and reproduce.
  • Ongoing Prevention: Because German cockroaches are notorious for being rapid reproducers, scheduled follow-up services are often necessary, along with sanitation improvements, moisture control, and sealing gaps to prevent reinfestation.

Oriental Cockroaches

What is an Oriental Cockroach?

A dark, glossy Oriental cockroach (water bug); frequently found in damp crawl spaces, basements, and foundation areas in Vancouver and Portland.

The oriental cockroach is the darkest in color of the four Pacific Northwest species, often appearing quite glossy and dark brown or black. 

Both males and females can typically grow to over an inch in length and possess large wings (although neither uses them to fly).

Oriental cockroach nymphs will take much longer than other species to develop (up to a year), but will remain the same color through to adulthood.

How We Treat Oriental Cockroaches

  • Inspection: Oriental cockroaches are commonly linked to damp conditions, so inspections concentrate on crawl spaces, basements, floor drains, utility rooms, and exterior foundation areas where excess moisture creates ideal harborage sites.
  • Treatment: Moisture-focused treatment often includes targeted residual applications, granular treatments around foundations, and bait placements in damp voids, along with addressing standing water and drainage issues that attract this species.
  • Ongoing Prevention: Oriental cockroaches are strongly associated with moisture; ongoing control depends on improving ventilation, repairing leaks, sealing entry points, and scheduling follow-up visits to ensure populations remain under control.

Helping Prevent Cockroaches from Spreading

Cockroaches are not only unsettling, but they’re a health threat. They are known to carry over 30 diseases, including Salmonella and E. Coli. The pests find will gain access into your home a variety of ways, whether it’s under your door or through your plumbing. And if they get into your home, they can live in your walls — without you knowing for months.

While it may be disturbing to hear, know that if you have one cockroach in your home, you likely have more. A single cockroach can not only multiply on its own for years without the help of a male, but cockroaches also reproduce at an alarming rate. This is why it’s important to find a company that is well-versed in cockroach control.

Frequently Asked Questions About Cockroach Extermination

While cockroaches do thrive in places where food is readily available, they most likely did not just appear there overnight.

Cockroaches are very adept at hitching a ride in the least expected places. They are frequently carried into homes via grocery bags or in sacks of vegetables.

They can also find their way into luggage in hotel rooms, or into shopping bags or totes.

So, if you see a cockroach, it does not mean that you are a poor housekeeper. It just means that a new visitor has arrived.

Unfortunately, as the saying goes, for every cockroach you see, there are many that you don’t see. These invasive insects multiply and lay eggs quickly and can become a much larger problem if they aren’t stopped as soon as they’re spotted.

While roaches are often carried into homes and businesses via grocery sacks, tote bags, luggage, and other packages, sometimes they manage to find their way in through cracks under doors, windows, or other structural weaknesses in buildings.

Sealing these entrances with caulk or other sealants may help prevent new cockroaches from entering, but it does nothing to kill the ones already present.

The best way to fully rid your home or business of cockroaches is to hire a professional exterminator who is trained to remove different types of cockroaches.

While even the cleanest homes can get cockroaches, it is true that roaches love dirt and crumbs. They especially like to gather in areas with cardboard and paper on the floor. Therefore, keeping materials such as this picked up and put away will go a long way toward discouraging cockroaches.

Keeping floors swept, vacuumed, and mopped will also help. Cockroaches are always on the lookout for food and water, so keeping food crumbs swept up and spills is just as important.
