Roaches are one of the most common pest problems in American homes. They are also one of the most difficult pests to get rid of. There are many different species of roaches, but all have one thing in common: they prefer to live in dark, moist places, and they are experts at seeking out humans.
Why? Because we humans often and unwittingly provide the perfect environment for roaches to thrive. Our homes are excellent sources of food, shelter, and water.
As we’ve already mentioned, roaches can be notoriously difficult to get rid of. Removal can be even more complicated if you have roaches in your walls.
Are you wondering how to get rid of roaches in walls? Then you’ve come to the right place.
Let’s Talk About Roaches
Roaches are not only difficult to get rid of, but they can also be dangerous to your health.
Cockroaches are hard-bodied insects that live in colonies in warm, dark places like sewers and basements. They are one of the most common pests in the United States, as we mentioned above.
Cockroaches belong to the order Blattodea. There are over 4,000 species of cockroaches in the world. The most common cockroach is the German cockroach (Blattella germanica), which is also known as the sewer roach. Other common species include the American cockroach (Periplaneta americana), Australian cockroach (P. australasiae), brown-banded cockroach (Supella longipalpa), and oriental cockroach (Blatta orientalis).
If you’re here looking into how to get rid of roaches in walls, it’s important to take a moment to discuss the different types of roaches you might be dealing with. Correctly identifying your roach problem is key to ensuring you are treating it effectively and efficiently.
The American Cockroach
The American cockroach is the largest of the species and the most common pest in the United States. It’s about one inch long, is reddish-brown with a pale yellow band behind its head, and has wings that are shorter than its body. It is also known as the water bug or Palmetto bug, because of its preference for living in moist areas like kitchens and bathrooms.
The American cockroach is also one of the most common roach species found in homes and businesses throughout the United States.
Female American cockroaches produce an egg case about once every two weeks that contains about 30 eggs each. The female carries this egg case for about two weeks before dropping it to the ground and leaving it there to hatch on its own. The American cockroach can live up to one year if conditions are ideal.
The Brown Banded Cockroach
The brown banded cockroach is about half an inch long and has two dark stripes on its wings. It can be found outdoors near trees, under rocks and logs, or inside buildings. It prefers to live outdoors in warm weather but will come indoors to seek shelter from cold temperatures. This species of cockroach can be identified by the two dark bands on its wing covers, which are visible when it flies away from danger.
The brown banded cockroach prefers damp locations such as sewers and septic tanks where it can hide during daylight hours on moist substrates such as wood chips or mulch in landscaping areas around homes.
The German Cockroach
The German Cockroach was introduced into New York City in 1894 and has since spread throughout much of North America, including Canada, Mexico, and South America. It prefers warm climates and can be found in apartments or other buildings with favorable conditions such as steam heat and food sources such as garbage or pet food. This cockroach has become resistant to many insecticides due to its high reproductive rate and ability to survive long periods without food or water.
The Oriental Cockroach
The Oriental cockroach is another invasive species of cockroach that arrived in the United States in the 1920s. It’s now found in southern states, including Florida and Texas. This cockroach has a tan body with two dark longitudinal lines on its back.
The Oriental cockroach can live for up to two years and has a relatively long life cycle. The female lays her eggs on a safe surface such as cardboard or paper and then hides them away so that they aren’t exposed to light or predators. After about two weeks, the eggs hatch into nymphs that look like smaller versions of adults but have no wings yet. The nymphs are white at first but turn darker over time.
The Smoky Brown Cockroach
The smoky brown cockroach is a medium to large species of cockroach, reaching around 4 cm (1.5 in) in length. It is usually a dark brown or black color with two pale yellow spots on the pronotum (the shield-like area behind the head). The abdomen has two parallel white stripes along each side, and there are also two short white stripes on the wings.
The smoky brown cockroach is a common household pest that has made its way across the ocean from Africa.
Are Roaches Dangerous To People And Pets?
Roaches can often worsen chronic illnesses like allergies or asthma.
The fact that roaches are so prevalent is not surprising given how well they adapt to their environment. Roaches can live for weeks without food and months without water. They also have an amazing ability to withstand extreme heat or cold, which makes them ideal for surviving our fluctuating climate.
While all of this is amazing, it doesn’t distract from the fact that roaches are seen as gross, dirty, and disgusting pests. More importantly, a roach infestation in your home or walls can also be dangerous. In fact, roaches can spread a number of diseases, and they are some of the most common culprits for spreading food-borne illnesses.
One common way roaches can make you sick is through their droppings. Roach droppings contain bacteria and other germs that can make you ill if you come into contact with them. These droppings have also been shown to worsen chronic illnesses in people suffering from asthma or those struggling with compromised immune systems.
Roaches also carry various diseases, including salmonella, which can cause food poisoning; typhoid fever; dysentery; and cholera.
The diseases that roaches spread are often transmitted by eating food that’s been contaminated by their feces or urine. Roaches sometimes defecate on food items before they’re sold in stores, which can lead to contamination even if you don’t buy the item from a place where roaches have been found. However, people are most likely to be exposed to these diseases when they encounter roaches in their homes or offices.
In addition, roaches produce allergens that can cause an allergic reaction in some people who aren’t allergic to them but breathe in their droppings or shed skins.
Lastly, there’s evidence that roach infestations can contribute to mental health problems such as depression and anxiety. This makes perfect sense if you’re dealing with roaches and are wondering how to get rid of roaches in walls.
But why do you have roaches in your walls at all? Keep reading to find out.
Why Do I Have Roaches In The Walls?
Roaches are common pests that invade homes for a number of reasons.
Roaches are naturally attracted to moisture, so if there is excess moisture in your homes like leaky pipes or faucets, this could attract them. However, roaches are also attracted to food sources and will eat almost anything humans eat. They also seek out shelter from predators, and our basements, crawlspaces, and kitchen cabinets can make the perfect hideout for these pests.
If roaches have entered your home, you could very easily wind up with roaches not only running around your basement, bathroom, or kitchen but also in your walls.
The most common way for roaches to get into your walls is through cracks in the foundation or siding, or through vents or ducts. They can also enter through open doors or windows and if there are holes in your walls from previous infestations or other issues like plumbing leaks or plumbing problems that cause water damage.
The following are some common signs that it’s time for you to look into how to get rid of roaches in walls:
Roach droppings are 2mm to 4mm long brown or black pellets that are shaped like coffee grounds. If you see these droppings on your floor or walls, then it is usually an indication that there is a roach infestation in your home.
Egg capsules are flat, brown discs that contain eggs. They are about 1 mm in size and look like small pieces of paper glued together. These egg capsules can be found under appliances such as refrigerators and stoves where food crumbs accumulate.
Roaches lay their eggs inside these capsules so that when they hatch, there is food for them to eat nearby. Roach eggs hatch after 3 weeks but it takes up to 60 days for them to become adults if conditions are favorable for growth and development.
If you notice smear marks on your bathroom walls or even on your kitchen cabinets, then this is another sign that there is an infestation occurring somewhere in your home. Roaches leave behind smeared fecal matter on surfaces as they walk around.
The shed skins of roaches look like pieces of paper or tissue paper, but they are actually the exoskeletons of the roaches themselves. Once these shed skins accumulate on your walls or cabinets, then it becomes an easy way for you to identify whether or not there are any roaches living in those areas of your home.
One of the first signs that you have a roach infestation is seeing signs of cockroach damage in your home. This includes things like holes chewed through walls and other sources of food such as cardboard boxes and paper bags.
A Strange Odor
If you notice a strange odor coming from your walls at any point along with other signs of a roach infestation in your home, then this could be another sign that it’s time to look into how to get rid of roaches in walls. Roaches tend to leave behind an unpleasant smell when they die or decompose.
Strange Sounds From Walls
Roaches are nocturnal pests who are most active at night when we’re all asleep — which means they’ll be making noise as they scurry around our walls looking for food and water sources. You might also hear scurrying, hissing, or even chirping from inside your walls at night if you have a roach infestation. Yikes!

Safer Brand Diatomaceous Earth Crawling Insect Killer
Safer Brand Diatomaceous Earth Crawling Insect Killer is a safe, odorless, and non-staining powder that works to kill crawling insects like roaches on contact. This product can be used to rid your home of not only roaches but also ants, fleas, and other pests.
This product is made from a naturally occurring sedimentary rock that contains fossilized remains of diatoms (a type of hard-shelled algae). The powder also contains borax, which acts as a carrier for the DE. Borax is a natural mineral compound made up of sodium, boron, and oxygen that has been used for centuries as an insecticide.
Hot Shot Liquid Roach Bait
Hot Shot Liquid Roach Bait contains indoxacarb, which is a highly effective ingredient used in many different insecticides today because it has no known resistance from insects. Indoxacarb blocks the activity of glutamic acid-activated protein channels on nerve cells in insects’ nervous system, which leads to paralysis and death.
This ingredient efficiently kills cockroaches within 24 hours after consumption by direct contact with the bait or ingestion through contaminated food sources found near baits.
TERRO Ready-to-Use Indoor Roach Bait
TERRO Ready-to-Use Indoor Roach Bait is another product we recommend for those looking at how to get rid of roaches in walls. This product comes with a small tray that fits underneath your sink or behind your refrigerator; it attracts the roaches and entices them to eat the bait, then kills them.
Because roaches live in colonies, the roach that eats the bait often brings it back to the colony, effectively killing other roaches living inside your walls as well.

Roaches will feast on the instant potatoes, and when they take a drink the instant potatoes will expand inside of them, killing them instantly.

Leave the powdery substance out in areas you have noticed roach activity along with a bowl of water. For best results, use this method in conjunction with other methods of roach removal.
Kill Roaches Using A Mix of Bleach or Ammonia Spray
Roaches are repelled by strong smells like bleach and ammonia. If sprayed directly on roaches’ bodies, this spray will dehydrate them. Spray bleach or ammonia around your home and in areas you suspect roaches have been.
