Camel Cricket (Cave Cricket)
Ceuthophilus spp.
Camel crickets are an occasional pest concern in commercial buildings, primarily in facilities with below-grade or semi-underground areas providing the dark, humid conditions the species requires.
Basements, utility tunnels, crawl spaces beneath commercial buildings, and storage areas beneath loading docks are the most common commercial harbouring sites.
While the camel cricket causes less direct product contamination risk than some pest species, its presence during a customer visit or facility inspection creates a significant negative impression. In food facilities, its presence in any area accessible to food products represents a potential contamination risk and audit finding.
Habitat
Commercial facilities providing camel cricket habitat typically have one or more of: unfinished basement areas with concrete or soil floors, utility tunnels connecting buildings, storage areas with chronic moisture issues, crawl spaces beneath older structures, or areas with damaged waterproofing creating sustained wall or floor wetness.
These spaces may receive infrequent cleaning and inspection, allowing camel cricket populations to build undetected for extended periods.
Any commercial facility with below-grade or semi-enclosed dark spaces adjacent to exterior soil should include those areas in regular pest monitoring inspections.
Active Areas
Windsor
Tecumseh
LaSalle
Amherstburg
Lakeshore
Essex
Kingsville
Leamington
Chatham-Kent
Moderate prevalence in damp basements and crawl spaces across Chatham-Kent. Common in older homes with moisture issues.
St. Thomas
Moderate prevalence. Basements and crawl spaces in St. Thomas homes are typical habitat.
Seasonality
Commercial pest monitoring should note that camel cricket activity in below-grade facility areas is not strictly seasonal — established populations can persist year-round in stable indoor environments.
The primary ingress risk is in autumn (September–November), but inspections of harbouring areas should continue year-round. Commercial properties with known camel cricket history should increase inspection frequency in these areas during autumn and early spring.

Appearance
For commercial pest identification, the camel cricket is 12–25 mm, tan to brown, hump-backed, wingless, and conspicuously long-legged.
The absence of wings and the pronounced thoracic arch make it clearly distinguishable from house crickets and all other common commercial pests.
Staff encountering camel crickets in facility inspections should document the discovery area, number of individuals, and any associated moisture conditions, as this information is essential for effective investigation and corrective action planning.
- Distinctly hump-backed appearance — the thorax arches strongly upward when viewed from the side
- Very long antennae (often twice the body length) and extremely long, powerful jumping hindlegs
- Completely wingless and produces no sound — fully silent at all life stages
- Capable of surprisingly powerful, high, erratic jumps when startled — often directly toward the perceived threat
- Found in permanently dark, damp areas: basements, crawl spaces, garages, utility rooms
- Attracted to moisture and organic debris — feeds on fungi, decaying matter, and occasionally fabrics
Behaviour
In commercial facilities, camel cricket populations in below-grade areas can build to substantial numbers before discovery because the species makes no sound. Routine inspection of crawl spaces, utility areas, and below-grade storage rooms using a torch is the only reliable way to detect them before populations become large.
During facility inspections, the sudden explosive jump of a disturbed camel cricket from a harbouring site can startle inspectors and staff.
Commercial pest management plans should ensure that below-grade areas are included in monitoring programmes with appropriate inspection frequency.
Lifecycle
Females deposit eggs in moist soil or organic material. Development from egg through multiple nymph instars to adult takes several months. In stable indoor environments, breeding can occur year-round at low levels, with seasonal peaks in autumn. The number of eggs per female is variable by species but sufficient to establish persistent indoor populations in ideal harbouring conditions. Adults typically live one season.
Egg
Egg deposition in below-grade areas of commercial facilities indicates an established, reproducing population.
Discovery of egg masses during inspection of crawl spaces or below-grade storage areas should be documented and treated as confirmation of an established infestation requiring systematic intervention.
Nymph
Nymphs present in a commercial facility’s harbouring areas indicate established in-house reproduction, a more serious situation than adult-only ingress.
This discovery should escalate the management response to include comprehensive harbouring site treatment and moisture remediation.
Adult
Adults entering from the exterior in autumn and any adults from established indoor populations are the primary management target.
Commercial facilities should deploy sticky traps in harbouring areas to monitor adult population density. Any increase in trap catch should prompt investigation of moisture conditions and harbouring site integrity.
Signs You May Have a Problem
- Camel crickets found in sticky monitoring traps deployed in below-grade areas, utility tunnels, or crawl spaces during scheduled facility inspections
- Staff reports of startling jump encounters in basement storage areas, utility rooms, or crawl spaces
- Individuals found in or near food storage areas in below-grade commercial spaces, triggering a pest log entry and corrective action requirement
- Chewing damage on stored cardboard, packaging material, or fabric items in affected below-grade areas
- Damp conditions confirmed in crawl spaces or utility areas where camel crickets are discovered — moisture is always an associated finding
- Nymphs discovered alongside adults in an inspection area, confirming that the population is established and reproducing within the facility
Risks & Concerns
Commercial risks include contamination of stored products or surfaces in affected areas, staff distress from unexpected encounters, and audit findings if the animals are present in food-related areas.
The conditions sustaining camel cricket populations — chronic moisture, organic debris, poor lighting — are independently problematic for food safety and facility management.
A camel cricket infestation in a food storage or preparation area requires documented corrective action addressing both the pest and the contributing moisture conditions. In hospitality settings, customer discovery of camel crickets in accessible areas represents a serious reputational risk.
Prevention
- Include all below-grade and crawl space areas in the facility's regular pest monitoring programme
- Maintain crawl spaces and utility tunnels in a clean, dry condition with adequate ventilation
- Deploy sticky monitoring traps in all below-grade harbouring areas and review catches at each scheduled inspection
- Seal all exterior entry points at ground level and address all moisture infiltration issues in below-grade areas
- Ensure that below-grade storage areas are included in cleaning schedules and that organic debris and clutter are regularly removed
- Install permanent lighting in below-grade areas used for storage to deter camel cricket use of those spaces
DIY Control
- Deploy commercial sticky monitoring traps in all identified harbouring areas and review catches at each inspection visit
- Apply residual insecticide in below-grade harbouring sites using products labelled for commercial non-food areas
- Document all sightings, trap catches, and corrective actions in the facility's pest management programme
- Initiate moisture remediation as the primary long-term control measure
Professional Control
- Professional inspection of all below-grade areas including crawl spaces, utility tunnels, and basement storage with population assessment and documentation
- Targeted residual insecticide treatment in harbouring sites by licensed applicators using products appropriate for the risk zone
- Moisture assessment and remediation recommendations integrated into the corrective action plan
- Ongoing monitoring programme with scheduled inspections of below-grade areas included in the commercial pest management agreement
Frequently Asked Questions
Do camel crickets make noise?
The absence of chirping from camel crickets means they can establish large populations in basement and crawlspace areas without any auditory cue. Sticky trap monitoring is more useful than listening for activity.
What do camel crickets eat?
Camel cricket feeding damage to stored goods in basement areas is a real concern in larger infestations. Inspect stored items in affected areas for chew marks or frass.
How do I tell camel crickets from house crickets?
The humpbacked profile and very long legs make camel crickets unmistakable once you know the identification features.
How do I reduce camel crickets in my basement or crawlspace?
Dehumidification, harborage removal, sticky trap monitoring, and professional perimeter treatment are the standard management tools for commercial camel cricket infestations.
Are camel crickets dangerous?
Camel crickets pose no health or safety risk. Customer reactions to their appearance are the primary commercial concern.
Why do camel crickets jump so erratically?
The erratic jumping behaviour is alarming to customers and staff encountering camel crickets unexpectedly. Prompt treatment of infested basement or crawlspace areas reduces this nuisance.
