You walk into the basement, turn on the light, and something with outrageously long legs launches itself toward your face. Congratulations: you may have met a camel cricket, nature’s way of testing whether you can remain calm while carrying a laundry basket.
Also called cave crickets or spider crickets, these humpbacked insects thrive in cool, dark, humid locations. They are usually harmless, but a large population can become an unpleasant household nuisance, leave droppings on surfaces, and occasionally damage stored belongings. More importantly, their presence may point to excess moisture, foundation gaps, or clutter that deserves attention.
Professional camel cricket control is not about spraying every corner until the basement smells like a chemistry lab. The most reliable strategy combines correct identification, inspection, moisture control, exclusion, trapping, sanitation, and carefully targeted pesticide use only when necessary.

What Is a Camel Cricket?
Camel crickets belong to the insect family Rhaphidophoridae. They are related to other members of the order Orthoptera, which includes crickets, grasshoppers, and katydids, but they look very different from the familiar black field cricket sitting outside and performing a free midnight concert.
The name “camel cricket” comes from the insect’s arched, hump-like back. “Cave cricket” describes its preference for dark, damp habitats, while “spider cricket” refers to its extremely long legs and antennae. Despite that nickname, it is not a spider. A camel cricket has six legs, while a spider has eight.
Several camel cricket species occur in the United States. Native species in the genus Ceuthophilus are common, while an Asian greenhouse camel cricket has also become widespread in many parts of the country. From a homeowner’s perspective, the control strategy is generally the same: remove moisture, shelter, food sources, and access.
How to Identify Camel Crickets
Correct identification prevents wasted treatments. A product or method designed for cockroaches, spiders, or chirping field crickets may not address the conditions attracting camel crickets.
Look for a Hump-Shaped Body
Viewed from the side, a camel cricket has a noticeably rounded or arched back. Its body may be light tan, mottled gray, reddish brown, or dark brown. Adults commonly measure about one-half inch to one and one-half inches long, excluding their enormous legs and antennae.
Check for Very Long Antennae and Hind Legs
Camel crickets have threadlike antennae that may extend beyond the length of the body. Their muscular rear legs are built for powerful jumps. When frightened, they often leap unpredictably toward movement rather than carefully plotting an attack. It feels personal, but it is usually just a panicked escape response.
Notice the Lack of Wings
Adult camel crickets are wingless. They cannot fly, and they do not have the wing structures that house and field crickets use to produce their familiar chirping songs.
Listen for Absolutely Nothing
Camel crickets do not chirp. A loud cricket serenading you from behind the furnace is more likely a house cricket or field cricket. A silent, humpbacked insect bouncing around the crawl space is a stronger match for a camel cricket.
Count the Legs When Possible
Camel crickets have six legs. Cellar spiders and other long-legged arachnids have eight. House centipedes have many more legs and move rapidly across walls and floors rather than jumping with enlarged hind legs.
Physical identification characteristics supported by NC State Extension, University of Maryland Extension, University of Missouri Extension, and University of Minnesota Extension.
Where Camel Crickets Hide
Outdoors, camel crickets usually live in cool, sheltered places with steady moisture. Common hiding spots include:
- Under logs, stones, boards, and landscape timbers
- Inside woodpiles and stacks of lumber
- Beneath thick mulch, leaf litter, and ground cover
- Under decks, porches, sheds, and outdoor equipment
- Near drainage areas, foundation walls, and shaded vegetation
Inside a building, they are most often discovered in basements, crawl spaces, garages, utility rooms, bathrooms, laundry rooms, storage areas, wall voids, and spaces near fireplaces. They favor locations that are dark, quiet, cluttered, and humid.
Extreme weather can increase indoor activity. Heavy rainfall may flood outdoor hiding places, while extended hot or dry weather can push camel crickets toward cooler, more humid structures. Late summer and fall are common seasons for indoor encounters in many regions.

Why Are Camel Crickets in Your House?
A camel cricket infestation usually requires three ingredients: moisture, shelter, and an entry route. Your basement may be accidentally advertising all three.
Excess Moisture
Leaking pipes, condensation, poor crawl-space ventilation, clogged gutters, groundwater seepage, and damp foundation walls can create ideal conditions. A dehumidifier may reduce airborne moisture, but it will not repair a plumbing leak or correct water flowing toward the foundation.
Easy Entry Points
Camel crickets can enter through foundation cracks, gaps beneath doors, damaged screens, dryer vents, crawl-space access doors, basement windows, utility penetrations, siding gaps, and openings around plumbing or HVAC lines.
Outdoor Harborage Near the Foundation
Firewood stacked against the house, dense ivy, deep mulch, leaf piles, lumber, stones, and miscellaneous clutter provide protected staging areas. From there, the trip indoors may be only a few inches.
Indoor Clutter
Cardboard boxes, paper piles, stored clothing, and objects resting directly on the floor create hiding places and reduce airflow. Clutter also makes inspections harder, allowing a population to grow unnoticed.
Are Camel Crickets Dangerous?
Camel crickets are primarily nuisance pests. They are not venomous, do not sting, and are not considered serious medically important household insects. Their signature move is an alarming jump, not an organized assault on your ankles.
They also do not normally cause structural damage like termites or carpenter ants. However, a large, long-standing population may leave dark fecal smears on floors, joists, walls, or stored objects. When normal food is limited, camel crickets may nibble organic debris, cardboard, paper, fungi, dead insects, or stained fabrics. Meaningful damage is uncommon, but garments, linens, and other stored items should not be left exposed in an infested, humid room.
University sources generally describe camel crickets as nuisance pests, while NC State notes possible damage to stored garments and linens during unchecked infestations.
How to Inspect for Camel Crickets Like a Professional
Do not begin by chasing the first cricket you see. Start by identifying where the population is concentrated and why that location is attractive.
1. Inspect After Dark
Camel crickets are generally more active at night. Enter the suspected room quietly with a flashlight and check along walls, behind stored objects, beneath sinks, around floor drains, near water heaters, and beside foundation openings.
2. Follow the Walls
Many crawling insects travel along edges rather than crossing open floors. Inspect wall-floor junctions, corners, sill plates, utility lines, and the perimeter of crawl spaces.
3. Look for Moisture Clues
Check for condensation, wet insulation, plumbing drips, discolored wood, damp concrete, musty odors, clogged drainage, and water stains. The cricket may be the messenger. The moisture problem is often the actual story.
4. Search for Droppings
Heavy activity may produce dark smears or spots on joists, walls, floors, and stored objects. Concentrated droppings can help identify frequently used hiding or resting areas.
5. Use Sticky Traps as Monitoring Tools
Place numbered sticky boards along walls, in corners, behind appliances, near crawl-space doors, and beside suspected entry points. Record how many crickets each trap catches. The busiest traps reveal where corrective work should begin.
Continue monitoring after treatment. A declining trap count tells you the plan is working. A trap that remains busy may indicate an overlooked leak, gap, or outdoor harborage.

How to Get Rid of Camel Crickets Step by Step
Step 1: Vacuum Visible Crickets
A vacuum is one of the fastest low-toxicity tools for removing camel crickets indoors. Use a hose attachment or shop vacuum to collect adults, nymphs, shed material, and debris from corners and wall edges.
Empty the vacuum outdoors into a sealed trash bag. Vacuuming provides immediate relief, but it must be paired with moisture control and exclusion. Otherwise, you are simply operating a cricket shuttle service.
Step 2: Reduce Indoor Humidity
Run a properly sized dehumidifier in damp basements or enclosed storage areas. Improve air circulation, keep interior doors open when appropriate, and avoid allowing boxes or furniture to block airflow against foundation walls.
In crawl spaces, moisture correction may require drainage improvements, vapor barriers, insulation repairs, ventilation changes, or professional encapsulation. Building design and local climate matter, so avoid assuming that opening vents is always the correct solution.
Step 3: Repair the Moisture Source
Inspect plumbing, appliance connections, floor drains, gutters, downspouts, grading, window wells, and foundation walls. Extend downspouts away from the structure, correct soil that slopes toward the house, and repair water intrusion rather than repeatedly drying the same puddle.
Building experts generally recommend controlling moisture at its source instead of relying only on a last-line defense such as a portable fan or dehumidifier.
Basement moisture correction guidance supported by University of Minnesota Extension and EPA indoor environmental recommendations.
Step 4: Remove Indoor Hiding Places
Replace deteriorating cardboard boxes with sealed plastic containers. Store belongings on shelving rather than directly on the floor. Leave space between storage units and walls so you can inspect, clean, and maintain airflow.
Discard unnecessary paper, fabric scraps, wood pieces, and miscellaneous basement clutter. Keep pet food, birdseed, and other dry products in tight containers.
Step 5: Seal Entry Points
Use appropriate materials to close cracks around windows, doors, foundations, vents, pipes, cables, and mechanical lines. Install tight-fitting door sweeps and replace damaged weatherstripping. Screen crawl-space vents and repair broken window screens.
Pay special attention to the garage door and crawl-space access door. A gap that looks small from standing height may resemble a luxury entrance to a camel cricket.
Step 6: Modify the Exterior
Move firewood, lumber, bricks, stones, and plant debris away from the foundation. Trim ground cover and shrubs so they do not touch siding. Avoid deep organic mulch directly against the house; a dry gravel strip near the foundation may provide less shelter.
Clean leaves from window wells, improve drainage, and remove clutter beneath decks. Elevate garbage containers or place them on a hard surface to eliminate damp hiding spots underneath.
Step 7: Deploy Sticky Traps
Place glue boards along travel routes, not randomly in the middle of the room. Good locations include corners, wall edges, behind the washer, beside utility penetrations, under shelving, and near crawl-space entrances.
Keep traps away from children and pets. Check them regularly and replace dusty or full boards. Sticky traps are useful both for reducing a small population and measuring whether prevention work has succeeded.
Step 8: Consider a Labeled Pesticide Only When Necessary
For persistent or heavy infestations, an exterior barrier treatment or labeled bait may supplement exclusion and moisture control. Treatment is generally more useful around outdoor entry points, foundation walls, vents, windows, doors, and crawl-space access areas than as indiscriminate spraying throughout living spaces.
Use only an EPA-registered product whose label specifically permits control of crickets in the intended location. Follow all directions regarding application sites, amounts, protective equipment, ventilation, pets, children, and reentry. More pesticide does not produce more professionalism; it produces more pesticide.
Confined crawl spaces require special caution because ventilation may be poor and safe access may be difficult. A licensed pest management professional is often the better choice for pesticide work in these areas.

Camel Cricket Control Methods That Often Fail
Spraying Without Fixing Moisture
A pesticide may kill exposed insects, but the room remains attractive to replacements. Persistent humidity can also contribute to mold, odors, damaged materials, and other pest problems.
Using Total-Release Foggers
Foggers distribute pesticide into open air and onto exposed surfaces, but camel crickets often hide in protected cracks, voids, clutter, and crawl spaces. A fogger does not repair a leaking pipe or close a foundation gap.
Relying on Ultrasonic Devices
Plug-in ultrasonic pest devices are not a substitute for inspection, exclusion, drying, and monitoring. Even the most optimistic electronic beep cannot install a door sweep.
Sealing Only the Visible Crack
Finding one gap does not mean you have found every entry route. Inspect the entire lower exterior of the building, including utility penetrations, vents, basement windows, doors, siding transitions, and crawl-space access points.
Leaving Full Glue Traps in Place
Old traps lose effectiveness as they collect dust, insects, and debris. They also stop providing useful monitoring information. Date each trap and replace it when necessary.
How to Prevent Camel Crickets From Returning
A professional prevention program is simple enough to summarize: keep the structure dry, sealed, uncluttered, and unattractive.
- Inspect basements and crawl spaces for leaks several times a year.
- Clean gutters and direct downspouts away from the foundation.
- Maintain door sweeps, weatherstripping, screens, and vent covers.
- Keep mulch, dense vegetation, firewood, and debris away from exterior walls.
- Store belongings in sealed containers on raised shelving.
- Use sticky traps as an early-warning system in previously affected areas.
- Vacuum occasional invaders before they accumulate.
- Investigate sudden population increases after heavy rain or prolonged dry weather.
This approach follows integrated pest management, or IPM. Rather than depending on routine pesticide applications, IPM uses inspection, monitoring, sanitation, habitat modification, physical exclusion, and the lowest-risk effective treatment when action is necessary.
IPM principles supported by current EPA guidance emphasizing prevention, monitoring, exclusion, and reduced reliance on routine pesticides.
When to Call a Pest Control Professional
Professional help may be appropriate when:
- Sticky traps repeatedly catch large numbers of camel crickets.
- The infestation continues after moisture and entry points are corrected.
- Crickets appear throughout multiple floors or living spaces.
- The suspected source is an inaccessible wall void or confined crawl space.
- Water intrusion, damaged insulation, or structural deterioration is present.
- You cannot safely inspect or treat the affected area.
- Children, pets, respiratory concerns, or pesticide sensitivities complicate treatment.
Ask the company to explain where the crickets are entering, what environmental conditions support them, which nonchemical corrections are recommended, and exactly where any pesticide will be applied. A good technician should offer a plan, not merely a dramatic spray wand.
Frequently Asked Questions
Do camel crickets bite people?
Camel crickets do not normally bite people and generally avoid direct contact. Their sudden jumps are defensive escape behavior rather than aggression.
Why do camel crickets jump toward people?
They have limited defenses and use powerful, unpredictable jumps to escape perceived threats. They may leap toward movement or light simply because that direction offers an open route.
Can camel crickets reproduce indoors?
Some camel crickets may survive or reproduce in consistently humid, sheltered indoor environments, particularly crawl spaces, greenhouses, and damp basements. Many indoor individuals, however, have wandered in from nearby outdoor habitat.
Will a dehumidifier eliminate them?
A dehumidifier can make a basement less attractive, but it may not solve leaks, groundwater intrusion, outdoor hiding places, or entry gaps. It works best as one component of a broader control plan.
Will sticky traps solve a large infestation?
Sticky traps can remove insects and reveal activity zones, but a large population usually requires moisture correction, clutter reduction, exterior habitat changes, and exclusion.
Are camel crickets a sign that a house is dirty?
Not necessarily. Even a clean house can have camel crickets if it offers humidity and access. Clutter can make the problem worse, but drainage, foundation, ventilation, and plumbing issues are often more important.
Practical Experiences and Field Lessons From Camel Cricket Problems
The following experience-based scenarios reflect common patterns homeowners and pest professionals encounter. They are not claims about one specific property; they illustrate why successful control depends on diagnosis rather than cricket-by-cricket combat.
The Basement That Needed a Gutter Repair
One common situation begins with several camel crickets appearing near a basement wall after rain. The homeowner sets traps and catches a few, but new insects keep arriving. A closer exterior inspection reveals an overflowing gutter and a short downspout dumping water beside the foundation.
Once the gutter is cleaned, the downspout is extended, and a small basement window gap is sealed, trap counts fall sharply. The lesson is easy to miss: the indoor insects were the visible symptom, but the water management problem was the cause. Treating the basement alone would have produced temporary results.
The Crawl Space With Plenty of Shelter
Another typical case involves a humid crawl space filled with cardboard, scrap lumber, leftover insulation, and forgotten construction materials. Sticky boards catch camel crickets throughout the space, especially near the access door and plumbing lines.
The successful cleanup starts with removing unnecessary materials, placing needed items on raised shelves, repairing the access door, sealing utility gaps, and addressing damp soil. Traps remain in place to measure progress. The population decreases gradually rather than disappearing overnight, which is normal when many hiding places existed.
The main lesson is that clutter is not merely unattractive. It creates stable humidity pockets, blocks inspection, protects insects from disturbance, and prevents air from moving across surfaces.
The Garage Where Spraying Was Not Enough
A homeowner may repeatedly apply an indoor insecticide along garage baseboards yet continue seeing camel crickets. Inspection outside the garage reveals ivy touching the siding, firewood stacked against the wall, and a worn rubber seal beneath the garage door.
After moving the firewood, trimming the vegetation, replacing the door seal, and placing traps along both sides of the garage, activity drops. This experience demonstrates why perimeter conditions matter. Killing a cricket after it enters is less efficient than removing the protected habitat and doorway that delivered it.
The Laundry Room With a Quiet Leak
In another common scenario, camel crickets are repeatedly found behind a washing machine. The room looks clean, and indoor humidity seems normal. Moving the appliance reveals a slow supply-line leak that has dampened the wall and flooring.
Repairing the hose, drying the area, checking for damaged materials, and sealing the nearby pipe opening solve the recurring problem. Without moving the appliance, the moisture source might have remained hidden for months.
The Importance of Monitoring After Cleanup
Homeowners sometimes stop the project as soon as visible crickets disappear. Professionals continue monitoring. Numbered sticky traps left near former hot spots can reveal whether the population is truly declining or has merely shifted to another corner.
For example, empty traps near the furnace but continued catches near a basement window suggest that the moisture correction worked while an entry point remains open. Monitoring turns pest control from guesswork into a simple evidence-based process.
The broader experience is consistent across homes: camel crickets are easiest to control when treated as an environmental clue. Vacuuming handles today’s insects. Drying, sealing, organizing, and modifying exterior habitat prevent tomorrow’s insects. That combination is what makes the job professional, even when the person holding the flashlight is wearing pajamas.
Conclusion
Camel crickets may look like spiders designed by a committee with too many legs in its budget, but they are usually manageable nuisance pests. Identify them by their humpbacked, wingless bodies, extremely long antennae, oversized hind legs, silent behavior, and preference for damp, dark spaces.
For lasting camel cricket control, begin with inspection and monitoring. Vacuum visible insects, reduce humidity, repair leaks, remove clutter, seal entry points, move exterior harborage away from the foundation, and use sticky traps to track progress. Reserve pesticides for persistent infestations, and use only products labeled for the pest and application site.
The goal is not simply to kill every cricket you see. It is to change the conditions that made your home appealing in the first place. Do that successfully, and your basement can return to its proper purpose: storing holiday decorations you promise to organize next year.
