Surinam Cockroaches

Surinam cockroaches. Suriname roaches, which are tropical cockroaches, are the most active in hot and humid weather conditions, making Florida an ideal habitat.

They are most active and problematic outside of our homes, and they don’t enjoy being indoors.

Warm, moist soil beneath rocks, leaf mounds, woodpiles, and other debris are preferred by them.

These roaches are also known as “greenhouse roaches.” They prefer the soil inside greenhouses.

Surinam cockroaches are nocturnal, like other cockroaches. They are most active at night, when they feed on plants and cause extensive damage to them.

General Information

Surinam cockroaches are occasionally discovered in indoor environments across the United States and other areas with warmer climates.

Tropical insects, scientifically known as Pycnoscelus surinamensis, are commonly found hiding in potted plants, soil and mulch from their natural habitats.

Surinam cockroaches can still cause damage in the buildings they inhabit, despite not being considered household pests in the same manner as other cockroach species.

The Surinam cockroach is thought to have been first discovered in the country. As a result, Carl Linnaeus, a Swedish naturalist, named it Pycnoscelus surinamensis.

Suriname cockroaches are the only kind that exist. Through a process known as parthenogenesis (unfertilized eggs are laid by females), these females may reproduce asexually.



A burrowing cockroach species, the Surinam cockroach (Pycnoscelus surinamensis) is found in greenhouses.

It is a widespread plant bug that has spread from tropical and subtropical parts of the globe to temperate climates, where protective habitat such as greenhouses provide shelter for individuals who are inadvertently imported in the soil of plants.

It has evolved numerous clonal strains from its sexual progenitor P. It has a nearly entirely female population and reproduces via parthenogenesis. Indicus is an Indian name.


The length of adult Surinam cockroaches ranges from 18 to 25 mm. On most areas of the body, their bodies are dark brown or black, and glossy.

The similar oriental cockroach Blatta orientalis has a glossy surface on all segments, while the back sections of the abdomen have a rough, dull surface.

Adults can have either a wing or no wing at all. Males have longer wings than females, but they are not good flyers in either sex. Brown or olive brown wings are possible.

The pronotum (head shield) of winged adults is diamond-shaped and somewhat broader than the wings, with a pale stripe around sections of the border.

Small and mostly hidden, the cerci are sensory organs at the end of the abdomen.

The reproduction of Pycnoscelus surinamensis is exclusively parthenogenesis, with embryos arising from unfertilized eggs. They reproduce via parthenogenesis, with thelkytokous offspring being almost entirely female.

Males are completely unknown in several populations. 30 to 36 young are born alive when eggs hatch internally. After hatching, the ootheca’s remnants are ejected from the host and devoured by the newborn nymphs.


While it also hides in other cracks and crevices around such places, such as beneath boards, this cockroach is typically discovered hiding in the soil of potted plants or interiorscapes.

It can wreak havoc on commercial flowers in greenhouses by feeding on foliage and fruit.

Outside buildings in humid, warm regions of the nation, it may also be discovered. In the United States, for example, Only females have been discovered in this species, which appears to be parthenogenetic.

The egg capsule is retained by the female and gives birth to live children. A capsule contains 24 average eggs.


Behavior and Habitat of Surinam Cockroaches

The egg capsule is retained in the abdomen of the female Surinam cockroach, who gives birth to live offspring.

In the United States, no males have been discovered, and reproduction is not required. South Florida, Texas, Louisiana, and humid tropical and sub-tropical climates are where you’ll find Surinam cockroaches.

These are earth-burrowing insects that can harm a wide range of plants. In potted plants, Surinam cockroaches are often brought into homes, shopping malls, and restaurants.

No male service.

In North America, there are no Surinam cockroaches. Only female offspring are produced by Surinam cockroaches, which are always female.

Surinam cockroaches are a parthenogenetic species, and they reproduce without the need of male participation. We know what you’re thinking, “What about the birds and the bees?”

The parent female clone her daughters. As a result, just one Surinam cockroach can become a serious problem.

The United States and Canada, but notably Virginia and the southeast Gulf Coast, have discovered Surinam cockroaches (Pycnoscelus surinamensis).

Cockroaches from Suriname can only survive indoors in the northern parts of the country due to their cold tolerance.

In our region, roaches from Suriname are mostly seen burrowing in the soil of indoor plant displays at shopping malls, restaurants, workplaces, greenhouses, and other structures.

Parasite Host

P. is a species of plant that can be found in the Caribbean and Central America. Parasitic roundworms Oxyspirura mansoni and Oxyspirura parvorum infect the eyes of poultry, and surinamensis serves as an intermediate host.

O = OK The chicken eyeworm, also known as MSO, may cause mild conjunctivitis to severe ophthalmia and substantial vision loss in its final hosts: chickens, turkeys, guineafowls, and peafowls.

The life cycle of a P. osculans egg starts with it passing through a bird’s lachrymal duct, then being swallowed and excreted.

The eye worm larvae migrate up the oesophagus and pharynx to the bird’s eye, while surinamensis cockroaches devour their feces, producing larvae.

If O is used, this would be a good time to use it. The notabilis moth is found in many regions of the globe, particularly in tropical and subtropical locations where P. notabilis may be found.

The term “permanent” has been used to describe surinamensis.


Surinam Cockroach Habitat and Food Source

In Virginia and the Southeast Gulf Coast of Florida, Louisiana, and Texas, this cockroach species is quite established.

The United States is home to no males of this species. Australia, as well as humid tropics across the globe, are home to this species. It does not breed indoors and spends the majority of its time outdoors.

As a result, it has been designated as a pest insect. It can be seen in malls and zoos in Northern states, mostly in atriums and potted plants brought from Florida by the Southern.

In areas with thick layers of mulch, heavy ground cover, and landscape timbers, Surinam cockroaches establish huge populations around landscape beds.

Only indoors in Northern areas can these roaches tolerate chilly temperatures. Suriname cockroaches may be found all the way up to Canada in the indoors.

Piles of firewood, leaves, mulch, lumber piles, and other outdoor harborages are home to Surinam cockroaches. They shun bright environments and prefer moist, gloomy settings.

Cockroaches hide in barrels, holes, cracks, and crevices in building walls; under stones and mulch; and under wood. Cockroaches from Surinam dig three to four inches into the ground.

Nymphs and incubating females are housed in burrows they create.

During the night, when they come out in full force to gnaw the stems of plants, they are omnivorous and mostly feed on a wide variety of plants.

Surinam Cockroach Infestation

That is excellent news for these garden dwellers, who are substantially more comfortable in soil and dirt than in your basement. The bad news is that if you aren’t careful, your garden might be overrun with these females.

With certain types, you don’t have to worry about removing your food scraps, but you must keep an eye on your plants! Unlike other roaches, Surinam cockroaches feast on fresh plant growth rather than omnivores.

The dishes include potted plants, flowers, tree leaves, and even weeds, so keep an eye on your petunias for bite marks.

The fact that these cockroaches are thriving despite the lack of a male in the United States for quite some time is particularly interesting.

Parthenogenesis, which means no male is necessary in the process of reproduction, is the reason for this.

As a result, they have been extinct for a long time, and the females are the only ones who carry on their genes.

These insects are considered a damaging pest because of their habitat and diet, and they may cause significant damage to gardens over time.

This species is a quick breeder because it does not need to find a mate and the females can reproduce on their own.

As a result, just a few of your Surinam cockroaches can quickly grow into an infestation and do significant damage to your garden.



P. has an unusual quality about it. Parthenogenesis, a sort of asexual reproduction in which embryos develop from unfertilized eggs, is the mode of reproduction for surinamensis.

P. is a common abbreviation for the word “pepper.” Thelytokous parthenogenesis, a form of parthenogenesis in which progeny are practically predominantly female clones, is used by surinamensis to reproduce.

In about 1% of known animal species, thelytokous parthenesis is known.

In several cockroach species, when females are isolated from males, parthenogenesis occurs in the optional teslkytokous form.

This includes the common household pests Blatta orientalis, Blattella germanica, and Periplaneta Americana. It is the only way of reproduction for surinamensis, which is obligatory parthenogenesis.

P. was formerly classified under a taxonomy. Surinamensis is a species that reproduces both sexually and asexually in certain populations, but only sexually in others.

Only P. parthenogenotes was known to do obligatory parthenogenesis.

Until 2003, when it was classified as Phyllodromica subaptera, this species was known as surinamensis. P. can be found in several asexual forms. Most Mediterranean nations are home to subaptera.

Surinam Cockroach Control

First, there’s the line with 1. To identify the type of cockroach that has invaded suspected infestation locations, call in a professional exterminator.

2. Large bait stations and sticky traps are placed around the base of infested plants by a pest control professional to capture pests as they leave.

In active Surinam cockroach harborages, an exterminator may use granular cockroach baits.

Foundations, mulches, plantings, potted plants, and any other infested area may all be treated with residual insecticides.

Treating the home’s barriers with insecticide may help to significantly reduce Surinam cockroach populations.

3. Plants that include Surinam cockroaches must be removed and treated off the premises if they are to be exterminated.

Are Surinam Cockroaches Dangerous?

Our temperature-controlled houses aren’t suitable for Surinam cockroaches because they need extremely high heat and humidity levels to live. Surinam cockroaches get inside most often through a potted plant or in or on it.

Surinam cockroaches pose a bigger danger to plants than they do to humans, so if these roaches get into your house, they may transmit harmful bacteria and diseases.

Problems Caused by Surinam Cockroaches:

If you move them to a new environment, surinam cockroaches can live and thrive inside.

Suriname cockroaches have the potential to create infestations that may wreak havoc on houseplants if they are not detected and allowed to reproduce.

Surinam cockroach invasions on a wider scale may cover the floor vegetation in greenhouses and retail malls, resulting in unattractive landscaping and damaging plant store business.

DIY and Green Solutions for Surinam Cockroach Control


First, remove the 1. Have a look around, please. Before bringing potted plants into your home, make sure to inspect them closely for signs of infection.

2. Spread it out! To make Surinam cockroaches less comfortable, thinly spread mulch piles.

3. Put a stop to it! To keep Surinam cockroaches out of your home, fill any cracks or crevices in the foundation. Tight-fitting screens should cover all foundation and attic vents.

4. Do some yardwork! Remove dead leaves from flowerbeds near the base of the plant. Remove landscape timbers by stacking firewood on a rack. Pull weeds and cut grass very short.

5. The fact that the number is five is what makes it special. Tease them! Tease them until they beg for mercy!

A excellent way to control these roaches is to use granular roach bait. Water-resistant products are common on flowerbeds and in damp settings.

Soak the soil where Surinam cockroaches have been burrowing with liquid insecticide. The staying power of insecticide will be affected by the sun and rain.

To keep a Surinam cockroach-free, reapply treatments and repeat the previous stages.

How to Get Rid of Them

Surinam cockroaches can be controlled using granular roach bait. Bait is water-resistant, allowing it to be used in flowerbeds and other damp places.

Drenching the soil where the roaches have been burrowing may be effective with liquid insecticide.

These treatments must be reapplied frequently due to the impact of sun and rain. Pest control experts making these treatments and controlling these pests is often more convenient for homeowners.
