Most Common Cockroaches in the US
The American cockroach was probably originally native to tropical Africa. It was spread by ship and is now found in the entire tropical and subtropical belt. In the temperate latitudes it occurs, due to trade, in the warehouses of the port cities, but also in the tropical houses of zoological gardens.
The females fasten the 8 mm long egg container to a suitable surface a few hours to four days after being pushed out, usually in crevices with high humidity near a feeding place. At an average room temperature, development is complete after 600 days.
In the warmer states, the American roach occurs regularly in public buildings, in restaurants, bakeries, grocery stores, hospitals, hotels, storage facilities and in the food processing industry. Under warm conditions, the species is also found outside of buildings in gardens and sports facilities as well as in the field.
In the USA, the American cockroach is the most common species in the canal systems of cities from which the above-mentioned habitats in buildings are settled. The American cockroach can feed on all sorts of organic substances, but it shows a pronounced preference for fermenting food components.
How to identify cockroach types in the US?
Here’s how to know what type of cockroaches became the unwanted occupier of your house. No matter what type, approaches to getting rid of roaches are similar for all pests.
Identification of larger cockroaches

- They are bright red-brown in color.
- The wings of the males are longer than the body. In females they just cover the abdomen.
- American roach can run quickly (even fly at very high temperatures).
Australian cockroaches (Periplaneta australasiae)
- This red-brown cockroach species is similar in appearance to the American cockroach (Periplaneta americana).
- It is about 25-35mm tall.
- The Australian cockroach can be easily identified by a yellow stripe along the outer leading edge of each wing (yellow shoulder).
Oriental cockroaches (Blatta orientalis)
- Oriental cockroaches reach a size of 25 to 30 mm.
- They are dark brown to black.
- In the females the wings are rudimentary, in the males they cover three quarters of the abdomen.
- Because oriental cockroaches are big and heavy, they are relatively difficult to climb and mainly walk on the ground.
Identification of smaller cockroaches
Brown ribbon cockroaches (Supella longipalpa)
- Brown band cockroaches are 10 to 14 mm in size.
- They are yellow-brown in color. The pronotum is surrounded by a light, translucent border.

- These pests grow to be between 12 and 15 mm.
- They are brown and have two dark stripes on the chest.
- The wings of both males and females are as long as the body or a little longer.
- German cockroaches run very fast and can climb (smooth) walls.
How do cockroaches get into the house?
Roaches do not infest living spaces because of a lack of hygiene or cleanliness. The pests are usually introduced via food packaging, used kitchen appliances or with holiday luggage. They can also move into the house or apartment from adjacent food factories or restaurants. Here are the most common ways cockroaches enter the house:
- Though food storage cupboards with large, opened food packages in private households
- Restaurants and pubs can leave food supplies in large sacks outside. Storage costs are high and a new delivery can be made within a few hours.
- Grocery stores are regularly checked by pest controllers and set traps. If a roach infestation is found, an expert distributes insecticidal gels at certain points in the supermarket and in the storage room. But the infestation can occur at any time.
As soon as they are in your home, however, the roaches multiply rapidly. An infestation should be combated as soon as it is recognized. However, it is difficult to spot the pests in time: during the day, cockroaches hide in hiding places. They only come out of their hiding places at dusk or at night and are only discovered then.
If you see a cockroach during the day, the infestation is already very strong. In this case, be sure to contact a professional pest controller.
How do you know if you have roaches in your home
Even if you don't see any pests, there are several signs that could indicate a cockroach infestation:
- In their developmental stages, the insects molt several times. The old skin usually remains in the vicinity of the nests as a translucent shell. Sometimes it is also eaten by fellow species.
- Cockroaches also usually lay their egg packets, which are about the size of half a coffee bean, close to their shelter.
- In addition, the vermin excretions can indicate an infestation. They look like crumbs from coffee powder and are about a millimeter long.
- The dots often run in a track on walls or other vertical surfaces.
- Roaches usually live together in larger populations and communicate and orientate themselves using species-like fragrances that are sometimes perceptible to humans as a penetrating smell.
- Damage to food and packaging also suggests that cockroaches have spread in the apartment.
- The same applies to any living or dead roach specimens found.
Be careful: You should dispose of captured animals in a tightly closed, airtight bag with the residual waste.

Home Remedies that Declare War on Cockroaches
Laurel: If there's one thing cockroaches can't stand - besides bright light - it's the smell of laurel. Simply spread a few leaves of the plant in the place where the cockroaches have made themselves comfortable such as kitchen. The insects will run away quickly - but this is no guarantee that they won't just make themselves comfortable in another place.
Catnip: This plant works in the same way as bay leaf. Just spread them where you think the roaches are - or all over the house.
Vinegar and pepper: in combination you can really make life difficult for the roaches. Because vinegar is considered a barrier for cockroaches. If you sprinkle some more pepper on it, you hardly have a chance to overcome it. So once you've identified the hiding place for the insects in the kitchen, simply spread vinegar and pepper around it - as far as your soil can tolerate vinegar - and they will have a hard time getting to their food sources around the house.
Baking soda and sugar: mix the two agents in equal parts and scatter around the house. The roaches are attracted by the sugar and taste it - but the baking soda produces gases that kill the pests.
Borax is used in households for soap and water softeners. But it also works against cockroaches. As soon as they come into contact with it, the water is withdrawn from them and they perish.
Best cockroach treatment methods in 2021
Roaches are one of the most difficult enemy insects for humans to control. Scientists have proven that these tiny creatures can survive a nuclear attack and many natural disasters.

10 Steps to Effectively Removing Cockroaches from the House
Anyone who has been infected by cockroaches definitely needs an action plan. While households deal with their particular situations, there are a number of steps that will be helpful in roach eradication.
Step 1. Identify the problem. Set detention traps in the areas where you have seen cockroaches to make sure they are cockroaches you are dealing with and understand the scale of the problem, i.e. how severe the infestation is.
Step 2. Examine the house. Any kitchen, old furniture, cardboard, and other old stuff will most likely act as a shelter for these pests. You'd better dispose of this stuff as eggs cannot be disposed of in the crevices. Then find any cracks and crevices in the walls, baseboards, etc. and caulk or repair them. Keep the food in containers or in the refrigerator.
Step 3. Thoroughly clean up the infested space and make a habit of doing this on a regular basis. Try cleaning hard-to-reach areas with a vacuum cleaner, soapy water, and detergent.
Step 4. Start with natural and safer solutions. Maybe they'll solve the problem and no longer have to resort to heavy chemicals. Instead, baking soda, diatomaceous earth, and boric acid, as well as home-made traps like a glass trap and duct tape, are good options.
Step 5. If these methods are found to be ineffective, re-monitor the presence of the insects. The infestation may be too severe and you need professional help from modern methods. This increases the chance of getting rid of roaches once and for all. You can find some useful tips on how to make the right choice in the article below.
Step 6. If you still want to get rid of roaches through your efforts, try poisonous traps. It will take you some time to see the result, as the most effective poisons are slow to act but kill a large number of pests. Apply closed bait stations in kitchens and premises where children and pets can reach the substance. Gel poisons without bait stations are more effective, but less safe.
Step 7. Don't limit your pest control practice to a single application. Repeat the application making sure that you have covered all the ways the cockroaches have in your house and kitchen especially.
Step 8. Apply ultrasonic pest control devices which get rid of roaches. When adult roaches are gone, they are unable to lay eggs that grow into IGRs are ideal here, as this solution is aimed at future generations.
Step 9. If you still have roaches but their numbers are low, use fast-acting solutions that kill insects on contact. These are sprays and aerosols that contain various insecticides. As soon as a cockroach shows up, spray it and it will be killed!
Step 10. Set ultrasonic pest chasers in the places where the cockroaches will still appear such as kitchen. This will help you eliminate the remaining roaches.
What are some quick ways to keep roaches out?
When it comes to pest control, it may be tempting to try do-it-yourself methods like electronic cockroach repellent. However, this often winds up being more trouble than it’s worth.
First, it’s important to consider effectiveness issues. Of course, electronic repellent probably won’t work. Other DIY options like bait stations may only partially eliminate cockroaches, and boric acid can be easily misapplied. With methods like these, following label instructions and professional training is very important.
Electronic cockroach repellent supposedly works by emitting ultrasonic, or very high frequency, sound waves. This noise is supposed to cause response which can confuse, and may even kill, certain pests like roaches.
These systems plug into wall outlets and can be purchased at any home hardware store. The sound is too high for humans to hear and should cause no disruption for members of the household. Some consumers may find electronic cockroach repellent preferable because of its ease of use. They may even perceive it as a more humane method of dealing with household pests.
Cockroaches are world champions in camouflage. Since the insects hide during the day and only become active at night in the dark, they usually remain undetected in households for a long time. German cockroach, Oriental cockroach or full-grown American cockroach - they are all gross.
A cockroach rarely comes alone. Therefore, where you see one or two crawling, hundreds are waiting in their hiding place. If you suspect that roaches are up to mischief in your own home, you should consider getting rid of them by protecting your home and its inhabitants with simple and effective electronic pest control device treatment.
If you want to eliminate roaches, you should rely on roach treatment help from modern and safe pest control methods such as electronic repelling. What’s best, ultrasounds also chase away any larvae that could now hatch from previously laid eggs. Roach control treatment such as roach bait treatment and traps are ineffective for combating a cockroach population. You should refrain from spraying insecticides - there is a risk of poisoning if sprays of this type get into the human respiratory tract. In contrast, electronic devices are completely harmless to humans and pets. It’s time to move on from poisons to natural and safe methods of getting rid from cockroaches.
