Small Cockroach – What type? (Are you in TROUBLE?)

If you have just spotted a small cockroach in your house, it’s time to act quickly.

Small roaches are the most infectious ones and can proliferate.

However, you may have spotted a baby roach, which could be an offspring of a large species. The large species of cockroaches typically tend to live outdoors.

If the roach you have spotted is around 1-2 cm, it’s either a German roach, Asian roach, or Brown-Banded. It can also be a close sibling to the mentioned one.

If it’s one of these, you can be in trouble.

If the tiny roach is a baby roach of an American Cockroach, then you are not in much trouble.

Identify the type of Small Roach

Cockroaches come in different sizes; some of the biggest cockroaches, like one found by a Facebook user Locutor O. Paniagua on September 4, 2020, measured 4.5 inches, holding a world record. However, small roaches have more propensity to infest homes than bigger roaches.

Almost 90 percent of the time, when you spot a tiny cockroach, it will be either a German Roach or a german baby nymph.


All tiny cockroaches are pretty identical in appearance. It’s tough to distinguish the species as a german roach is very similar to an Asian Cockroach.

A brown-banded roach has two strips on its back, but the strips usually are not visible due to the identical wings on top. The bands can be seen in baby brown-banded roaches.

Generally, small roaches are light brown, tannish colored, with thin and flat bodies. The wings are translucent and folded on each other. Two distinctive bands run across their bodies.


Most tiny roaches, including the German cockroach, Brown-banded cockroach, Asian cockroach, measure between 0.3 inches to 0.5 inches long.

Early instar nymphs are about 2 to 3 mm; middle instar nymphs are about 8 to 9 mm long.

    Types of Small Cockroaches

    As explained above, there are not many types of small roaches. Its 90 percent of the cases, you will spot German roach.

    1. German Cockroach
    2. Brown Banded Cockroach
    3. Asian Cockroach
    4. Wood Cockroach (Identical to Asian Roach and won’t infest homes)
    5. Red Runner Roach (You won’t find them as they are highly desierable as feeder roaches)
    6. Dubia Roaches (You won’t find them as they are highly desierable as feeder roaches)


    Most of the little roaches have wings, except the baby nymphs who lack wings until puberty.

    To know whether your place is infested withlittle roaches, look for cockroach smear marks around the damp corners. They are an indication of an infestation.

    Small Roaches Babies vs Large Roaches Babies

    A baby nymph is quite small in size and you can confuse them with a small roach. However, its quite easy to distinguish a large cockroach baby vs a fully grown small roach.

    Small Roaches have Wings

    A fully grown small roach will always have wings, while a small roach baby or a large roach baby won’t have wings.

    Color of Baby Roaches

    The color of a baby roach canhelp it distinguish it from small roach babies vs large roach babies.

    Tiny red roaches are usually babies of American Roaches, which generally live in sewer systems and don’t like infesting homes. However, they can still infest if it’s dark, humid, and with plenty of scrap food.

    Tiny black roaches are usually german baby roaches as their babies will appear dark black at the early stage of life. Therefore, spotting baby german roaches rings an alarm of already ongoing infestation.

    Habitat and Eating Habits of Small Roaches

    German Roaches (The most common type of small roaches) are the timidest roaches out there and usually crawl around the house at night to stay away from encountering humans. Mini roaches love a warm and humid environment with plenty of garbage, spilled food, easy-to-access drains, and a safe place to nest and lay eggs; plenty of them.

    Small roaches are omnivorous, but they love to eat filth, decomposing food, garbage, starchy, and sweet food items. Mini roach dwells inside gutters, sewage lines, bathroom drains, closed cabinets, fridges, old worn-out clothes, and behind the furniture.

    Do Small Roaches Bite?

    Roaches are timid creatures, and they rarely bite humans. However, in case of heavy infestation and when the food is scarce, they can sometimes mistake humans for food hence biting.

    Small Roaches can be a Problem

    The pace with which roaches reproduce is astonishingly fast. For example, one German cockroach can give rise to almost 360 baby roaches in her lifetime.

    Once the small roaches enter the house, they nest at difficult places to reach. They will love to nest around the electric back panel of the fridge, under the furniture in the attic, and damp basements.

    Tiny roaches can also be a problem for your neighbors; they will soon migrate and infest their house or apartment.

    The exoskeleton from a molting nymph, the poop, and saliva from small roaches can trigger allergies and asthma episodes. They can also transfer bacteria, including Salmonella Typhi, from sewage to your food.

    Therefore, getting rid of Skinny roaches should always be your top priority.

    Sometimes, we can mistakenly refer to bed bugs as small roaches, which are a problem of their own. Here is a complete article on bugs that looks just like cockroaches.

    How to get rid of small roaches?

    Small roaches are difficult to exterminate because they usually nest under challenging areas to reach. Moreover, because they are shy and nocturnal, they rarely visit rooms during the day.

    However, I recommend you to read seven ways to get a cockroach out of hiding before attempting to kill small roaches.

    To get rid of small roaches, use one of the following methods,

    Method 1: Use Gel Baits

    Baits are the most effective method for killing small roaches; that’s why professional exterminators use them. Because of its fragrance, bait tricks small roaches into consuming it and killing them.

    The market is flooded with several baits to kill baby roaches. However, I recommend using Advion Cockroach Gel Bait because of its superiority and ease of use over other baits.

    To use bait for killing baby roaches, all you need to do is,

    1. Place the advion gel bait at multiple location around the house including attic, basement corners, kitchen cabinets, drawers, bathroom and entry points.
    2. Wait for next few days to see the results.

    You can also prepare your own bait using boric acid and mix them with consumable ingredients. However, it Is a bit messy and slow method.

    Method 2: Use Bait Traps and Killers

    Using traps to kill small roaches is also quite effective, but it is slower.

    Hot Shot Liquid Cockroach Trapper and Killer is the best trapper; it is chemical-free and safe to use around pets and kids.

    All you need to do is,

    1. Place the traps at recommended locations around the house especially near the roach nest.
    2. Remove the traps after a week.

    Method 3: Using Insecticide Spray or Foggers

    The quick and lethal action of using insecticide spray makes it a method of choice for many. However, the results are not lasting because small roaches usually hideaway.

    For this method to work, spray the insecticide generously at the hiding places and wait for 25 minutes before ventilating the room.

    I recommend Bengal Roach Killer because it contains Nyler, which prevents reinfestation for up to 6 months.

    Preventing Small Roaches Infestation

    Preventing small roaches from infesting your house is not a difficult job. All you need to do is,

    1. Clean your House Regularly.
    2. If your floor is carpeted vaccum clean it regularly and if tiled mope it with phenol.
    3. Cover drains and garbage bins properly especially at night.
    4. Fix leaking water and sewrage lines.
    5. Cover crevices and gaps in doors and windows with masking tape.
    6. Use Natural Bug Repellents to keep roaches at bay.
    7. Remove source of humidity and ventilate your home well.
    8. Fix lightning problems.
    9. Pick up clutter, spilled food and garbage.
    10. Maintain your wardroab and cabinets orderly.
    11. Use IGR spray to keep baby roaches from maturing into adult bugs.
