Identification
Physical Characteristics
Adult Shelfordella Cockroach can be identified by their distinctive physical features. They typically measure 15-28mm and display This species exhibits strong sexual dimorphism. Males are a striking orange to rusty-red color with yellowish wings that extend past the abdomen. Females are wingless (or have tiny, non-functional wing stubs), with a pear-shaped body that is a glossy, dark brown to black, often with creamy-white markings along the edges of the thorax and abdomen.. The dramatic visual difference between the sexes is the primary distinguishing feature. The colourful, winged male looks like a completely different species from the dark, wingless, beetle-like female. This dimorphism is much more pronounced than in other pest species like the American or Oriental cockroach. Their inability to climb smooth surfaces like glass or plastic is another key trait, which makes them easy to contain in captivity as feeder insects. When identifying them as pests, they are often mistaken for Oriental cockroaches due to the females' appearance, but the males are very distinct.
Key Identifying Features
The stark contrast between the sexes is the number one identifier. If you see slender, reddish-orange flying cockroaches together with stout, black, beetle-like wingless ones, it is almost certainly Shelfordella lateralis. Their inability to climb smooth surfaces is another useful clue, especially when they are found trapped in a smooth-sided sink or tub. Wing development: Males are fully winged and are capable, if somewhat clumsy, fliers. Females are effectively wingless and cannot fly.. Antennae: Long and thread-like in both sexes..
Similar Species
The wingless females are often confused with the Oriental cockroach (Blatta orientalis). However, Oriental cockroach females have small, non-functional wing pads, whereas S. lateralis females are virtually wingless. The males are quite distinct and not easily confused with other pest species. They are smaller and more brightly coloured than American cockroaches. Professional identification ensures accurate species determination for targeted control strategies.
Signs of Presence
No specific damage signs., including Feces are not a primary identification sign as they are dispersed outdoors. and Large infestations can produce a characteristic musty cockroach odor..
Biology & Lifecycle
Lifecycle Details
Habitat & Distribution
Preferred Environments
Shelfordella Cockroach typically inhabits In their native range (Central Asia, Middle East), they are found outdoors under stones, in leaf litter, and in animal burrows. As an invasive pest, they heavily infest outdoor man-made structures like water meter boxes, irrigation valve boxes, sewer systems, compost piles, and the voids of hollow concrete blocks.. Temperature preferences: They are a heat-loving species and do best in warm to hot climates. This is why they have become a major pest in the hot, arid regions of the southwestern United States..
Microhabitat Selection
Specific microhabitat requirements include Outdoors, their primary hiding spots are water meter boxes, cracks in pavement, expansion joints, and voids in retaining walls. They rarely infest the interiors of homes but can invade garages, basements, and wall voids connected to outdoor populations.. These locations provide shelter and breeding opportunities.
Urban vs. Natural Habitats
In its invasive range, it is primarily a suburban and urban pest associated with man-made structures and irrigation., with human-modified landscapes often providing ideal conditions for population establishment.
Distribution Patterns
Geographic Range
Shelfordella Cockroach is found across Not known to be established as a pest in Australia. It is considered a significant biosecurity risk.. Climate zones: Native to Central Asia and the Middle East. It has become a major invasive pest in the hot, arid regions of the southwestern United States..
Introduction History
Any presence in Australia would be the result of accidental importation. It is commonly bred overseas as a feeder insect, and illegal importation for this purpose poses a major biosecurity risk to Australia. States like Queensland have explicitly prohibited this species.
Current Distribution Patterns
No known spread in the wild in Australia. It is critical that any sightings are reported to biosecurity authorities immediately to prevent its establishment. Population densities vary based on local environmental conditions and habitat suitability.
Behavior & Diet
Activity Patterns
Primarily nocturnal. They remain hidden during the day and emerge at night to forage for food and water. Males may be attracted to lights. Peak activity typically occurs during optimal environmental conditions.
Feeding Behavior
Omnivorous scavengers, they will eat almost any organic material, including garbage, decaying plant matter, pet food, and dead insects. This generalist diet allows them to thrive in urban and suburban environments. Food source availability influences habitat selection and population distribution.
Social Interactions
Gregarious, they live in large, dense aggregations. They communicate using pheromones to signal food sources and suitable harbourages. Their tendency to form large colonies is a key reason they are successful as both feeders and pests. Not known to be territorial.
Dispersal Behavior
Dispersal is mainly through crawling and running. Males can fly, but they are not strong fliers. Human activity is the main driver of long-distance spread, through the transport of infested materials or via the pet trade. Understanding movement patterns aids in predicting infestation development.
Dietary Preferences
Primary Food Sources
Omnivorous scavengers, they will eat almost any organic material, including garbage, decaying plant matter, pet food, and dead insects. This generalist diet allows them to thrive in urban and suburban environments. Food preferences influence habitat selection and infestation patterns.
Nutritional Requirements
Essential nutrients include proteins, carbohydrates, and moisture sources that support growth and reproduction. Seasonal availability of preferred foods affects population dynamics.
Foraging Behavior
Foraging strategies involve systematic searching of potential food sources, with established trails and communication methods guiding group feeding activities.
Health Risks
Always consult healthcare professionals for medical concerns related to pest exposure.

Detection & Signs
Visual Inspection
Regular visual inspections focus on areas where Shelfordella Cockroach typically harbors. No specific damage signs.
Monitoring Tools
Professional monitoring tools include sticky traps, pheromone lures, and inspection equipment that enable early detection and population assessment.
Environmental Indicators
Large infestations can produce a characteristic musty cockroach odor. Seeing large numbers of fast-moving roaches swarming out of a water meter box or irrigation valve cover at night is a classic sign of a heavy infestation.
Professional Assessment
Professional inspection services provide accurate species identification and population assessment, enabling targeted treatment planning and monitoring protocols.
Prevention
Sanitation Measures
Focus on outdoor sanitation. Keep garbage cans sealed and clean them regularly. Remove yard waste like piles of wood, leaves, and rocks that provide harbourage. If you have a compost bin, ensure it is well-maintained and located away from the house foundation. Clean up fallen fruit from trees and avoid leaving pet food outdoors overnight, as these are easy food sources. Regular cleaning and proper food storage prevent population establishment.
Exclusion Techniques
This is a critical step to prevent outdoor populations from moving indoors. Seal all cracks and crevices in the foundation of your home. Use weather stripping on doors and windows. Install fine-mesh screens over all vents, soffits, and weep holes. Pay special attention to where utility lines (pipes, wires) enter the house and seal any gaps around them with caulk, copper mesh, or expandable foam. Sealing entry points and installing barriers provide long-term protection.
Environmental Management
Eliminate sources of moisture around your property. Repair leaky pipes, taps, and air conditioning drip lines. Ensure that sprinklers are not spraying directly against the house foundation. Improve drainage to prevent water from pooling near the house. Since they congregate in places like water meter boxes, ensuring these areas are dry can help deter them. Landscape management eliminates outdoor harborage sites.
Ongoing Maintenance
Regular maintenance and monitoring ensure continued effectiveness of prevention measures. Professional prevention programs provide comprehensive protection strategies.
Control Methods

Frequently Asked Questions
Why are Turkestan cockroaches used as feeder insects?
Turkestan cockroaches, or 'Red Runners', are popular feeder insects for several reasons. They breed very quickly, providing a continuous food source. They have a good nutritional profile for reptiles and other insectivores. Crucially, unlike many other feeder roaches, they cannot climb smooth surfaces like plastic or glass, making them easy to contain in a tub. Their active, fast-running behaviour also stimulates a natural hunting response in captive animals. These traits make them commercially valuable but also contribute to their potential as an invasive pest.
Is the Turkestan cockroach a pest in Australia?
Currently, the Turkestan cockroach is not considered an established pest in the wild in Australia. However, it is viewed as a serious biosecurity threat. Its success as an invasive outdoor pest in similar hot, dry climates in the United States shows that it could easily establish here, particularly in suburban areas. It is illegal to import or keep in many Australian states to prevent this from happening. Any suspected sightings should be reported to the Department of Agriculture, Fisheries and Forestry immediately.
How can I tell a Turkestan cockroach from an Oriental cockroach?
The easiest way to tell them apart is by looking at the males and females. A male Turkestan cockroach is a bright, reddish-orange colour and can fly. A male Oriental cockroach is a uniform dark brown to black and cannot fly. The females can look similar as both are dark and flightless. However, an Oriental cockroach female has small but visible wing pads, whereas a Turkestan female is practically wingless, appearing more like a beetle. The presence of the colourful males is the most definitive clue.
