Keith's Pro Tips

"Baby roaches are fast and evasive creatures that can be hard to identify at first glace. It would be best to learn what a baby roach looks like by first trapping them with a roach glue trap like the Solutions Pro Glue Board - Peanut Butter Scent. The most common way to identify a baby roach is to examine their color, size, and the lack of wings which later develop in its last developmental stages depending on the species."

Baby Roaches: A Complete Guide to Identification and Control

This page is a general guide that distinguishes each cockroach nymph stage (baby roaches) and explains what it means to see baby roaches in your home. Follow each cockroach control link within this DIY guide and use the recommended products for complete cockroach nymph removal.

Nothing brings on a shudder such as seeing cockroaches scurry across your floor, but this leads to the question what do baby roaches look like and how serious are they? Baby roaches, otherwise known as nymphs, can be just as harmful as their adult stages as they spend their time crawling through pipes picking up harmful bacteria and eating their own feces.

Nymph cockroaches cannot fly because their wings are not fully developed until the baby roach becomes an adult. For this reason, baby cockroaches tend to jump or scuttle causing them to hide in tight crack and crevices or other hard to reach places. If you have encountered one of these pests in your house, then most likely there is a nest nearby leading to the possibility of a current infestation or one about to begin.

Like other insects, baby cockroaches must molt multiple times before reaching adulthood. Depending on the cockroach, the baby roach can reach sexual maturity within 6 months to a year. Read on to learn more information about baby roaches, which will help to make it more quicker and easier to control the cockroach infestation before it gets out of hand.

What Does a Baby Roach Look Like

American Cockroach Nymph

The fastest way to identify between baby cockroaches and adult ones is to look for wings. During the nymph stage cockroaches will not have these wings, typically until 6 months to a year after hatching.

Roaches that are white in coloration means they are just freshly hatched. As they mature baby roaches will become darker in coloration, but will have no markings depending on the species. Listed below is the cockroach nymph characteristics of the most encountered roach species in the United States in order to determine which pest is infesting your home.

American CockroachesAmerican cockroach nymphs measure about one-quarter of an inch in length with soft bodies. In their first nymph stages the American cockroach nymph is gray-brown coloration. These nymphs can go through 6 to 14 molting's before reaching adulthood in about one to three months. After molting, the American cockroach nymph turns reddish-brown with its posterior siding of the thoracic and abdominal parts being a darker coloration.

German CockroachesThe nymphs of German cockroaches are usually dark brown to black in coloration with the same distinct parallel bands running across their heads as in their adult stages. When they hatch the German cockroach nymph is about 1/8 inch long and white in coloration for a short period. The biggest difference between a nymph and adult German cockroach is the absence of the wings, which sometimes occur after the sixth molting. When the environments temperature is ideal the German cockroach can complete its growth in 60 days.

Brown-Banded Cockroaches: Like German cockroach nymphs, the brown-banded cockroach is quite small measuring about 1/8 inches long. However, they can be told apart from German cockroaches with the absence of two dark pronotal stripes. In both their adult and nymph stage the brown-banded cockroach has two light brownish bands across the body at the base of the abdomen and at mid-abdomen. They will molt 6 to 8 times before reaching maturity, over a period of 276 days.

Oriental CockroachesOriental cockroach nymphs measure around one-quarter inch in length and range from red to brown as they develop. These cockroaches will become darker in coloration as they mature with the adult stage appearing almost black in coloration. Oriental cockroach nymphs go through 7 molts before reaching adulthood, which takes up to 1 year. In contrast to the American and German cockroach, these roaches will move much slower.

Smoky Brown CockroachesSmaller than the American cockroach, the smoky brown cockroach nymphs are about 3/8 inches long in length. They are dark brown to black in color and have two white bands on their body and tip of their antennae. Older nymphs become lighter in color appearing as reddish brown before reaching their smoky brown coloration. Upon hatching the smoky brown cockroach takes up to 320 days before becoming an adult.

What Does Each Baby Cockroach Share

  • Two long antennae.
  • Head hidden by a part of the thorax, along with mouth parts pointed backwards.
  • Have six spiny legs with three legs on each side of the thorax.
  • A cerci, which is two small appendages at the base of their body. They are used to sense vibrations through the air or ground to warn the roach of impending dangers.
  • Bodies are flat in shape and hard. Cockroach babies are usually wingless until the last stages of growth just as their about to become adults.

Are Baby Cockroaches Dangerous

Cockroach Droppings

It's unpleasant for any homeowner to think about, but each stage of cockroaches can carry all types of diseases to people. They can spread diseases and bacteria from crawling through various pipes, sewers, toilets, and garbage. These harmful pests will eat just about anything from their own or other pests fecal matter, deceased pests, and garbage material causing food or surfaces they come into contact with to become contaminated.

With their ability to travel through the smallest of openings baby roaches can further spread these bacteria and pathogens with their droppings, saliva, or direct contact. Of course, in their nymph stage these droppings will be smaller than their adult counterparts. Nymphs from larger cockroaches species excrete small, round droppings with ridges whereas nymphs from smaller cockroaches appear as as small black or brown specs.

How to Get Rid of Baby Cockroaches

Seeing one of these baby cockroaches is a sign of a much larger infestation or possibly a current one in your home. To protect yourself from pesticide material and cockroach bacteria, you will need to wear the proper personal protective equipment (PPE).

Quick control is needed when one baby cockroach is spotted in or around your home. To get rid of cockroach nymphs and adults, you will need to use several integrated pest management tools as well as cockroach sprays, gel baits, and long-lasting residual insecticides.

Step 1: Get Rid of Resources

Food Sealed in Plastic Container

To control a future cockroach infestation, you must first remove their resouces of food and water. Even if the nymphs or adults are removed, more can follow. Cockroach nymphs can survive off the smallest drops of food or water.

However, you can limit access to larger quantities of food by storing them into airtight or sealable plastic containers. This also includes using sealable plastic garbage bags for your trashcans and securing the lids. Trash cans should not be overfilled and be immediately disposed off to an outdoor garbage container that is several feet away from your homes foundation.

Garbage bags stored on the floor can entice cockroach nymphs with food aromas or provide small crumbs for the pest to feed on. Besides crumbs, these sites can also provide ideal habitats for cockroaches and nymphs to hide. Keep your kitchen, bathroom, and floors as tidy as possible by wiping off surfaces with soap and water and vacuuming the ground or furniture.

Most species of cockroach nymphs heavily depend on moisture for their survival. These pests can find these water sites from various sites in and around your home such as leaky pipes, rain gutters, and fallen leaves which collects moisture underneath as they decompose. Leaking pipes, plumbing, AC vents, or anywhere else in your home that collects water may need to be repaired.

Step 2: Apply Gel Baits

Apex Bait in Crevice

Apex Cockroach Gel Bait contains 11 different attractants which roaches like the American, German, Oriental, Smoky Brown, and other species including the nymph stages find irresistible. This gel bait is designed to kill roaches slowly once ingested, allowing the cockroach nymph to return back to areas where other cockroaches may be hiding. As other cockroaches ingest the deceased roach or its fecal matter they will also die thus eliminating entire infestations.

Once all other food and water sources have been secured, including pet food and water dishes and surfaces have been cleaned can you proceed with product application. We recommend not using household cleaners or detergents when applying Apex Cockroach Gel Bait as this may deter roach nymphs from consuming bait materials.

Determine how much Apex Cockroach Gel Bait to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment site in feet then multiply (length X width = square footage). Depending on the species of cockroach nymphs, the amount of Apex Cockroach Gel Bait will vary. To control small roaches like German Cockroaches, you will need to apply 3 drops of Apex Cockroach Gel Bait or approximately 0.0047 oz. of product per square yard. To control larger roaches like the American or oriental cockroach, apply 5 drops of product or 0.0071 oz. of product per square yard. It would be best to place this product on an index card for easy cleanup and application.

With a gloved hand, apply Apex Cockroach Gel Bait as a spot or crack and crevice treatment in your home. Place the appropriate amount of Apex Cockroach Gel Bait near roach harborages or where these pests have been active such as underneath baseboards and sinks, countertops, cabinets, and where the pipe penetrates the wall. Do not apply where insecticides have been recently used and only in areas out of reach of children and pets.

Within 3 to 5 days there should be a reduction in roach nymph activity. Allow 1 to 2 weeks to pass until roach activity is no longer witnessed.

Step 3: Residual Spray Indoors with Novacide Flea & Tick Killer

Novacide Treatment

Once one to two weeks have passed since the application of Apex Cockroach Gel Bait, you will then spray a residual insecticide indoors. Novacide Flea & Tick Killer is a powerful aerosol insecticide that combines four different chemicals, one of which is an insect growth regulator. This product is a synthetic pyrethroid that works by interfering with the roaches nervous system while the IGR pyriproxyfen prevents the insect from reaching sexual maturity, effectively stopping roach infestations from growing.

This effective roach killer comes in an ready to use aerosol can and once sprayed lasts up to 7 months. In your home, all food preparation surfaces and utensils should be removed prior to application and then utensils should be washed before use. Remove all pets, birds, children, and cover fish aquariums before spraying Novacide Flea & Tick Killer.

To apply Novacide Flea & Tick Killer, simply hold the can upside down at arms length and direct the spray toward the area to be treated from a distance of at least 36 inches. Spray for 10 seconds to treat an area of 100 sq. ft. (10 ft. X 10 ft.) but not to point of run-off or drip. Begin spraying from the back of your home towards the front, make sure to spray floor, carpet, and furniture within kitchen, bathroom, and in other labeled areas where roach nymph activity has been witnessed.

Because of the wide variety of floor types and finishes it would be best to test in a small, hidden area before full treatment with Novacide Flea & Tick Killer for color fastness or dulling. Avoid contact with antique finishes.

Do not enter or allow others like children and pets to enter the treated areas until vapors, mists, and aerosols have dispersed, and the treated area has been thoroughly ventilated and dried.

Step 4: Residual Insecticidal Spray Outdoors

Perimeter Spray

Cockroaches are prolific breeders that commonly invade the inside of homes by traveling through outdoor cracks and crevices or plumbing. Other species tend to infest the outside of your home as well as the inside like the American Cockroach. For this reason, you will want to spray a residual insecticide on your homes exterior foundation.

Supreme IT Insecticide is a bifenthrin insecticide concentrate designed for broad-spectrum control over 70 different insects, including cockroaches. Once applied this products residual will leave no offensive odor and continue to repel and kill cockroaches for up to 90 days. To use Supreme IT Insecticide you will need to apply this product with a handheld pump sprayer.

Determine how much Supreme IT Insecticide to use by measuring the square footage of your treatment area. To find the square footage, measure the length and width of the treatment area in feet then multiply (length X width = square footage). To find acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acreage). To treat cockroaches, apply 1 fl. oz. of Supreme IT Insecticide per 1 gallon of water per 1,000 sq. ft. of treatment area.

To mix, fill your handheld pump sprayer with half a gallon of water and add your measured amount of Supreme IT Insecticide. Add the rest of the water up to the 1 gallon line then close the sprayer and shake until solution is evenly mixed. Pump the sprayer a few times to produce a low pressure spray.

Apply your mixed solution as a perimeter treatment around your homes foundation by spraying 3 feet up the structure and 3 feet out. Treat the entry points that cockroach nymphs and adults can use to invade your home by spraying door and window frames, openings created by utility pipes, porches, garbage areas, lawn areas, garages, and other entry points.

Do not allow contact with treated surfaces by people or pets until spray has dried.
