Cockroaches are both unpleasant and unsanitary. Getting rid of roaches can be tricky because the two most common roach types (German or American roaches) are eliminated using different techniques. The first step to get rid of roaches is to identify which type of roach you have. To determine which type of roach you have, first look at their sizes. Afterwards, compare physical features and habitats from the information and links below. After determining what kind of cockroach you have, we have tips on how to inspect for roaches, critical sanitation/exclusion procedures, and best treatment options to get rid of roaches.

Roach Identification by Adult Size and Habitat

The first question that we ask when someone says that they have roaches is “Where are they living and how big are they?” Correctly identifying what kind of cockroach you have is vital and a key to successfully treating a roach infestation. Getting rid of smaller-sized adult roaches is different than getting rid for larger-sized adult roaches. Cockroaches are nocturnal and will scatter if disturbed. The young immature roaches look like the adults, but do not have wings. Once you have correctly identified the cockroach in your area, you can successfully choose treatment options to get rid of your roach problem. Within these pages, we have provided examples of the most common types of roaches found in the USA.

Smaller Types of Roaches

German RoachSmaller adult roaches include the German roach and the Brown-Banded roach. The most invasive of these two types of cockroaches is the German Cockroach .

The smaller German roach is just 1/2"-1 " in the adult stage. They have two stripes behind their heads and have a light/golden brown color. The Brown-Banded roaches have stripes along their wings. Both the German roach and Brown-Banded roach live and breed inside. Treatment for both these roaches would be the same. The German roach is the most common of the smaller roaches and the most difficult to control. You find these roaches in places that have water or food such as kitchens and bathrooms. These roaches commonly live behind and under sinks, stoves, and refrigerators. In commercial kitchens, they can be found in floor drains. They live in dark places and are nocturnal. It is very common to spot these roaches when you enter a kitchen or bathroom and turn on the light. These small, golden brown roaches will be seen scampering along the counters.

Habitat and Entry

These roaches do not forage from the outside but travel from one apartment/ suite unit to the adjoining unit. They are brought inside or hitchhike in items such as luggage, boxes and grocery products. German roaches live and breed inside; they can live all season long since they are in a warm, comfortable environment. German roaches can be brought in via luggage, furniture, handbags, or boxes from an infested location. During the warmer months, they can move from building to building. In commercial settings, they can move from one connecting unit to the next thru drop ceilings and common plumbing and electrical elements.

Health hazards of the German roach and Brown-Banded roaches

Carrying bacteria that is transmitted to humans, German cockroaches, and Brown-banded cockroaches are health hazards. The primary diseases are gastroenteritis including food poisoning, dysentery, and diarrhea. Asthma and allergies may be triggered by the German roaches' feces, body parts, or salvia that are circling in the air. Children are particularly affected by these hazards.

How to get rid of German and Brown-banded roaches

Identifying the presence of German or Brown-Banded roaches is essential for proper control measures. They breed inside and contaminate their living environments while most larger adult cockroaches do not reproduce inside. The most common larger roaches breed outside, and target treatment areas would be different.

German roaches and Brown-Banded roaches are primarily treated using roach baits and insect growth regulators. Other types of roaches such as the larger American roach are treated using insecticide concentrates sprayed outside and entry points to your house.

Using Roach baits and using growth regulators are kets to getting rid of these roaches. We have both roach baits and insect growth regulators (IGRs) combined in kits for greater savings.

The American roach is reddish brown and is about 1.5 " or longer. Many people refer to these types of roaches as water bugs or palmetto bugs. These larger sized roaches are not known to spread disease as compared to the German roach. All the treatment options are similar for the larger roaches.

Habitat and Entry

The American roaches are common in warmer climates or during the warmer spring, summer and fall months. They mostly live and breed outside and wander inside for water and food. They are often found inside after extreme weather conditions, like heavy rain or drought conditions. They mainly live outside in organic, mulch material. They will also be found in basements, woodpiles, attics, hollow trees, under roof shingles, and in attics. They are common in steam tunnels in the northern states in the USA. Most of the time, they breed outside. However, if conditions are right, they will reproduce inside. For example, you may find an American roach population behind a wall that has had a water leak causing a moist environment.

Health hazards of American roaches

Since American roaches move from sewers into homes or commercial establishments, they can be a health concern. They carry bacteria, viruses, and parasites on their bodies which lead to dysentery, diarrhea, and salmonella. These health concern are not at the same magnitude of the health concern from German roaches since most of the time they live and breed outside.

Sanitation and Exclusion

Sanitation and exclusion techniques are important tools in your roach control program. Roaches need food, water and a safe place to harbor. As much as possible eliminate the food, water, and harbor sources as you choose and apply your roach control treatment plan.

German and Brown-Banded Roaches

For the German roach type, it is critical to clean your kitchen and bathrooms while beginning a roach baiting program. This cleaning includes some deep cleaning in both the kitchen and bathrooms. Pay attention to crumbs and grease in the kitchen and unclean tubs, showers, bathroom countertops in the bathrooms. If you do not clean well, it will be more difficult to get rid of these types of roaches.

  • Keep clean dishes, kitchen sinks, counters and cabinets.
  • Keep pet food picked up.
  • Remove all grease and food particles by cleaning and vacumming. Do not leave any food out in the open and seal all food containers.
  • Remove indoor trash.
  • Get rid of cardboard boxes, empty soda bottles, and stored paper bags.

  • Remove trash regularly and kitchen clean
  • Keep dumpsters clean and use a tight lid on garbage cans.

If possible, inspect at night, since roaches are usually nocturnal. If you see German cockroaches during the daytime, it is an indicator of a significant infestation. When there is a musty type of smell, it indicates a roach infestation.

Inspection will help you identify the kind of roach that you have. Look for fecal droppings and egg cases. The smaller German and Brown-Banded cockroaches will leave fecal material that looks like black pepper. It is essential to remove these droppings as soon as possible because they can cause health problems such as asthma. Use a vacuum to pull up these droppings.
